Health system

From Wikipedia, the free encyclopedia
 
A health system, also sometimes referred to as health care system or as healthcare system, is the organization of people, institutions, and resources that deliver health care services to meet the health needs of target populations. 
 
There is a wide variety of health systems around the world, with as many histories and organizational structures as there are nations. Implicitly, nations must design and develop health systems in accordance with their needs and resources, although common elements in virtually all health systems are primary healthcare and public health measures. In some countries, health system planning is distributed among market participants. In others, there is a concerted effort among governments, trade unions, charities, religious organizations, or other co-ordinated bodies to deliver planned health care services targeted to the populations they serve. However, health care planning has been described as often evolutionary rather than revolutionary.

Goals

The World Health Organization (WHO), the directing and coordinating authority for health within the United Nations system, is promoting a goal of universal health care: to ensure that all people obtain the health services they need without suffering financial hardship when paying for them. According to WHO, healthcare systems' goals are good health for the citizens, responsiveness to the expectations of the population, and fair means of funding operations. Progress towards them depends on how systems carry out four vital functions: provision of health care services, resource generation, financing, and stewardship. Other dimensions for the evaluation of health systems include quality, efficiency, acceptability, and equity. They have also been described in the United States as "the five C's": Cost, Coverage, Consistency, Complexity, and Chronic Illness. Also, continuity of health care is a major goal.

Definitions

Often health system has been defined with a reductionist perspective, for example reducing it to healthcare system. In many publications, for example, both expressions are used interchangeably. Some authors have developed arguments to expand the concept of health systems, indicating additional dimensions that should be considered:
  • Health systems should not be expressed in terms of their components only, but also of their interrelationships;
  • Health systems should include not only the institutional or supply side of the health system, but also the population;
  • Health systems must be seen in terms of their goals, which include not only health improvement, but also equity, responsiveness to legitimate expectations, respect of dignity, and fair financing, among others;
  • Health systems must also be defined in terms of their functions, including the direct provision of services, whether they are medical or public health services, but also "other enabling functions, such as stewardship, financing, and resource generation, including what is probably the most complex of all challenges, the health workforce."

World Health Organization definition

The World Health Organization defines health systems as follows:
A health system consists of all organizations, people and actions whose primary intent is to promote, restore or maintain health. This includes efforts to influence determinants of health as well as more direct health-improving activities. A health system is therefore more than the pyramid of publicly owned facilities that deliver personal health services. It includes, for example, a mother caring for a sick child at home; private providers; behaviour change programmes; vector-control campaigns; health insurance organizations; occupational health and safety legislation. It includes inter-sectoral action by health staff, for example, encouraging the ministry of education to promote female education, a well known determinant of better health.

Providers

Healthcare providers are institutions or individuals providing healthcare services. Individuals including health professionals and allied health professions can be self-employed or working as an employee in a hospital, clinic, or other health care institution, whether government operated, private for-profit, or private not-for-profit (e.g. non-governmental organization). They may also work outside of direct patient care such as in a government health department or other agency, medical laboratory, or health training institution. Examples of health workers are doctors, nurses, midwives, dietitians, paramedics, dentists, medical laboratory technologists, therapists, psychologists, pharmacists, chiropractors, optometrists, community health workers, traditional medicine practitioners, and others.

Financial resources

There are generally five primary methods of funding health systems:
  1. general taxation to the state, county or municipality
  2. national health insurance
  3. voluntary or private health insurance
  4. out-of-pocket payments
  5. donations to charities
Most countries' systems feature a mix of all five models. One study based on data from the OECD concluded that all types of health care finance "are compatible with" an efficient health system. The study also found no relationship between financing and cost control. 

The term health insurance is generally used to describe a form of insurance that pays for medical expenses. It is sometimes used more broadly to include insurance covering disability or long-term nursing or custodial care needs. It may be provided through a social insurance program, or from private insurance companies. It may be obtained on a group basis (e.g., by a firm to cover its employees) or purchased by individual consumers. In each case premiums or taxes protect the insured from high or unexpected health care expenses. 

By estimating the overall cost of health care expenses, a routine finance structure (such as a monthly premium or annual tax) can be developed, ensuring that money is available to pay for the health care benefits specified in the insurance agreement. The benefit is typically administered by a government agency, a non-profit health fund or a corporation operating seeking to make a profit.

Many forms of commercial health insurance control their costs by restricting the benefits that are paid by through deductibles, co-payments, coinsurance, policy exclusions, and total coverage limits and will severely restrict or refuse coverage of pre-existing conditions. Many government schemes also have co-payment schemes but exclusions are rare because of political pressure. The larger insurance schemes may also negotiate fees with providers. 

Many forms of social insurance schemes control their costs by using the bargaining power of their community they represent to control costs in the health care delivery system. For example, by negotiating drug prices directly with pharmaceutical companies negotiating standard fees with the medical profession, or reducing unnecessary health care costs. Social schemes sometimes feature contributions related to earnings as part of a scheme to deliver universal health care, which may or may not also involve the use of commercial and non-commercial insurers. Essentially the more wealthy pay proportionately more into the scheme to cover the needs of the relatively poor who therefore contribute proportionately less. There are usually caps on the contributions of the wealthy and minimum payments that must be made by the insured (often in the form of a minimum contribution, similar to a deductible in commercial insurance models). 

In addition to these traditional health care financing methods, some lower income countries and development partners are also implementing non-traditional or innovative financing mechanisms for scaling up delivery and sustainability of health care, such as micro-contributions, public-private partnerships, and market-based financial transaction taxes. For example, as of June 2011, UNITAID had collected more than one billion dollars from 29 member countries, including several from Africa, through an air ticket solidarity levy to expand access to care and treatment for HIV/AIDS, tuberculosis and malaria in 94 countries.

Payment models

In most countries, wage costs for healthcare practitioners are estimated to represent between 65% and 80% of renewable health system expenditures. There are three ways to pay medical practitioners: fee for service, capitation, and salary. There has been growing interest in blending elements of these systems.

Fee-for-service

Fee-for-service arrangements pay general practitioners (GPs) based on the service. They are even more widely used for specialists working in ambulatory care.

There are two ways to set fee levels:
  • By individual practitioners.
  • Central negotiations (as in Japan, Germany, Canada and in France) or hybrid model (such as in Australia, France's sector 2, and New Zealand) where GPs can charge extra fees on top of standardized patient reimbursement rates.

Capitation

In capitation payment systems, GPs are paid for each patient on their "list", usually with adjustments for factors such as age and gender. According to OECD, "these systems are used in Italy (with some fees), in all four countries of the United Kingdom (with some fees and allowances for specific services), Austria (with fees for specific services), Denmark (one third of income with remainder fee for service), Ireland (since 1989), the Netherlands (fee-for-service for privately insured patients and public employees) and Sweden (from 1994). Capitation payments have become more frequent in "managed care" environments in the United States."

According to OECD, "Capitation systems allow funders to control the overall level of primary health expenditures, and the allocation of funding among GPs is determined by patient registrations. However, under this approach, GPs may register too many patients and under-serve them, select the better risks and refer on patients who could have been treated by the GP directly. Freedom of consumer choice over doctors, coupled with the principle of "money following the patient" may moderate some of these risks. Aside from selection, these problems are likely to be less marked than under salary-type arrangements."

Salary arrangements

In several OECD countries, general practitioners (GPs) are employed on salaries for the government. According to OECD, "Salary arrangements allow funders to control primary care costs directly; however, they may lead to under-provision of services (to ease workloads), excessive referrals to secondary providers and lack of attention to the preferences of patients." There has been movement away from this system.

Value-Based Care

In recent years, providers have been switching from fee-for-service payment models to a value-based care payment system, where they are compensated for providing value to patients. In this system, providers are given incentives to close gaps in care and provide better quality care for patients. 

Information resources

Sound information plays an increasingly critical role in the delivery of modern health care and efficiency of health systems. Health informatics – the intersection of information science, medicine and healthcare – deals with the resources, devices, and methods required to optimize the acquisition and use of information in health and biomedicine. Necessary tools for proper health information coding and management include clinical guidelines, formal medical terminologies, and computers and other information and communication technologies. The kinds of health data processed may include patients' medical records, hospital administration and clinical functions, and human resources information

The use of health information lies at the root of evidence-based policy and evidence-based management in health care. Increasingly, information and communication technologies are being utilised to improve health systems in developing countries through: the standardisation of health information; computer-aided diagnosis and treatment monitoring; informing population groups on health and treatment.

Management

The management of any health system is typically directed through a set of policies and plans adopted by government, private sector business and other groups in areas such as personal healthcare delivery and financing, pharmaceuticals, health human resources, and public health

Public health is concerned with threats to the overall health of a community based on population health analysis. The population in question can be as small as a handful of people, or as large as all the inhabitants of several continents (for instance, in the case of a pandemic). Public health is typically divided into epidemiology, biostatistics and health services. Environmental, social, behavioral, and occupational health are also important subfields.

Today, most governments recognize the importance of public health programs in reducing the incidence of disease, disability, the effects of ageing and health inequities, although public health generally receives significantly less government funding compared with medicine. For example, most countries have a vaccination policy, supporting public health programs in providing vaccinations to promote health. Vaccinations are voluntary in some countries and mandatory in some countries. Some governments pay all or part of the costs for vaccines in a national vaccination schedule. 

The rapid emergence of many chronic diseases, which require costly long-term care and treatment, is making many health managers and policy makers re-examine their healthcare delivery practices. An important health issue facing the world currently is HIV/AIDS. Another major public health concern is diabetes. In 2006, according to the World Health Organization, at least 171 million people worldwide suffered from diabetes. Its incidence is increasing rapidly, and it is estimated that by the year 2030, this number will double. A controversial aspect of public health is the control of tobacco smoking, linked to cancer and other chronic illnesses.

Antibiotic resistance is another major concern, leading to the reemergence of diseases such as tuberculosis. The World Health Organization, for its World Health Day 2011 campaign, is calling for intensified global commitment to safeguard antibiotics and other antimicrobial medicines for future generations.

Health systems performance

Since 2000, more and more initiatives have been taken at the international and national levels in order to strengthen national health systems as the core components of the global health system. Having this scope in mind, it is essential to have a clear, and unrestricted, vision of national health systems that might generate further progresses in global health. The elaboration and the selection of performance indicators are indeed both highly dependent on the conceptual framework adopted for the evaluation of the health systems performances. Like most social systems, health systems are complex adaptive systems where change does not necessarily follow rigid management models. In complex systems path dependency, emergent properties and other non-linear patterns are seen, which can lead to the development of inappropriate guidelines for developing responsive health systems.

An increasing number of tools and guidelines are being published by international agencies and development partners to assist health system decision-makers to monitor and assess health systems strengthening including human resources development using standard definitions, indicators and measures. In response to a series of papers published in 2012 by members of the World Health Organization's Task Force on Developing Health Systems Guidance, researchers from the Future Health Systems consortium argue that there is insufficient focus on the 'policy implementation gap'. Recognizing the diversity of stakeholders and complexity of health systems is crucial to ensure that evidence-based guidelines are tested with requisite humility and without a rigid adherence to models dominated by a limited number of disciplines. Healthcare services often implement Quality Improvement Initiatives to overcome this policy implementation gap. Although many deliver improved healthcare a large proportion fail to sustain. Numerous tools and frameworks have been created to respond to this challenge and increase improvement longevity. One tool highlighted the need for these tools to respond to user preferences and settings to optimize impact.

Health Policy and Systems Research (HPSR) is an emerging multidisciplinary field that challenges 'disciplinary capture' by dominant health research traditions, arguing that these traditions generate premature and inappropriately narrow definitions that impede rather than enhance health systems strengthening. HPSR focuses on low- and middle-income countries and draws on the relativist social science paradigm which recognises that all phenomena are constructed through human behaviour and interpretation. In using this approach, HPSR offers insight into health systems by generating a complex understanding of context in order to enhance health policy learning. HPSR calls for greater involvement of local actors, including policy makers, civil society and researchers, in decisions that are made around funding health policy research and health systems strengthening.

International comparisons

Health systems can vary substantially from country to country, and in the last few years, comparisons have been made on an international basis. The World Health Organization, in its World Health Report 2000, provided a ranking of health systems around the world according to criteria of the overall level and distribution of health in the populations, and the responsiveness and fair financing of health care services. The goals for health systems, according to the WHO's World Health Report 2000 – Health systems: improving performance (WHO, 2000), are good health, responsiveness to the expectations of the population, and fair financial contribution. There have been several debates around the results of this WHO exercise, and especially based on the country ranking linked to it, insofar as it appeared to depend mostly on the choice of the retained indicators

Direct comparisons of health statistics across nations are complex. The Commonwealth Fund, in its annual survey, "Mirror, Mirror on the Wall", compares the performance of the health systems in Australia, New Zealand, the United Kingdom, Germany, Canada and the United States Its 2007 study found that, although the United States system is the most expensive, it consistently underperforms compared to the other countries. A major difference between the United States and the other countries in the study is that the United States is the only country without universal health care. The OECD also collects comparative statistics, and has published brief country profiles. Health Consumer Powerhouse makes comparisons between both national health care systems in the Euro health consumer index and specific areas of health care such as diabetes or hepatitis.

Social determinants of health in poverty

From Wikipedia, the free encyclopedia

Health gap in England and Wales, 2011 Census
 
The social determinants of health in poverty describe the factors that affect impoverished populations' health and health inequality. Inequalities in health stem from the conditions of people's lives, including living conditions, work environment, age, and other social factors, and how these affect people's ability to respond to illness. These conditions are also shaped by political, social, and economic structures. The majority of people around the globe do not meet their potential best health because of a "toxic combination of bad policies, economics, and politics". Daily living conditions work together with these structural drivers to result in the social determinants of health.

Poverty and poor health are inseparably linked. Poverty has many dimensions – material deprivation (of food, shelter, sanitation, and safe drinking water), social exclusion, lack of education, unemployment, and low income – that all work together to reduce opportunities, limit choices, undermine hope, and, as a result, threaten health. Poverty has been linked to higher prevalence of many health conditions, including increased risk of chronic disease, injury, deprived infant development, stress, anxiety, depression, and premature death. According to Loppie and Wien, these health afflictions of poverty most burden outlying groups such as women, children, ethnic minorities, and the disabled. Social determinants of health – like child development, education, living and working conditions, and healthcare - are of special importance to the impoverished. 

According to Moss, socioeconomic factors that affect impoverished populations such as education, income inequality, and occupation, represent the strongest and most consistent predictors of health and mortality. The inequalities in the apparent circumstances of individual's lives, like individuals' access to health care, schools, their conditions of work and leisure, households, communities, towns, or cities, affect people's ability to lead a flourishing life and maintain health, according to the World Health Organization. The inequitable distribution of health-harmful living conditions, experiences, and structures, is not by any means natural, "but is the result of a toxic combination of poor social policies and programmes, unfair economic arrangements, and bad politics". Therefore, the conditions of individual's daily life are responsible for the social determinants of health and a major part of health inequities between and within countries. Along with these social conditions, "Gender, education, occupation, income, ethnicity, and place of residence are all closely linked to people's access to, experiences of, and benefits from health care." Social determinants of disease can be attributed to broad social forces such as racism, gender inequality, poverty, violence, and war. This is important because health quality, health distribution, and social protection of health in a population affect the development status of a nation. Since health has been considered a fundamental human right, one author suggests the social determinants of health determine the distribution of human dignity.

Definitions and measurements

Social determinants of health in poverty reveal inequalities in health. Health is defined "as feeling sound, well, vigorous, and physically able to do things that most people ordinarily can do". Measurements of health take several forms including subjective health reports completed by individuals and surveys that measure physical impairment, vitality and well being, diagnosis of serious chronic disease, and expected life longevity.

The World Health Organization defines the social determinants of health as "the conditions in which people are born, grow, live, work and age", conditions that are determined by the distribution of money, power, and resources at global, national, and local levels. There exist two main determinants of health: structural and proximal determinants. Structural determinants include societal divisions between social, economic, and political contexts, and lead to differences in power, status, and privilege within society. Proximal determinants are immediate factors present in daily life such as family and household relationships, peer and work relationships, and educational environments. Proximal determinants are influenced by the social stratification caused by structural determinants. According to the World Health Organization, social determinants of health include early child development, globalization, health systems, measurement and evidence, urbanization, employment conditions, social exclusion, public health conditions, and women and gender equality. Different exposures and vulnerabilities to disease and injury determined by social, occupational, and physical environments and conditions, result in more or less vulnerability to poor health. The World Health Organization's Social Determinants Council recognized two distinct forms of social determinants for health- social position and socioeconomic and political context. The following divisions are adapted from World Health Organization's Social Determinants Conceptual Framework for explaining and understanding social determinants of health.

Social position

Poverty gradient and severity

Within the impoverished population exists a wide range of real income, from less than US$2 a day, to the United States poverty threshold, which is $22,350 for a family of four. Within impoverished populations, being relatively versus absolutely impoverished can determine health outcomes, in their severity and type of ailment. According to the World Health Organization, the poorest of all, globally, are the least healthy. Those in the lowest economic distribution of health, marginalized and excluded, and countries whose historical exploitation and inequality in global institutions of power and policy-making, suffer the worst health outcomes. As such, two broad categories distinguish between relative severity of poverty. Absolute poverty is the severe deprivation of basic human needs such as food, safe drinking water and shelter, and is used as a minimum standard below which no one should fall regardless of where they live. It is measured in relation to the 'poverty line' or the lowest amount of money needed to sustain human life. Relative poverty is "the inability to afford the goods, services, and activities needed to fully participate in a given society." Relative poverty still results in bad health outcomes because of the diminished agency of the impoverished. Certain personal, household factors, such as living conditions, are more or less unstable in the lives of the impoverished and represent the determining factors for health amongst the poverty gradient. According to Mosley, these factors prove challenging to individuals in poverty and are responsible for health deficits amongst the general impoverished population. Having sufficient access to a minimum amount of food that is nutritious and sanitary plays an important part in building health and reducing disease transmission. Access to sufficient amounts of quality water for drinking, bathing, and food preparation determines health and exposure to disease. Clothing that provides appropriate climatic protection and resources to wash clothes and bedding appropriately to prevent irritation, rashes, and parasitic life are also important to health.  Housing, including size, quality, ventilation, crowding, sanitation, and separation, prove paramount in determining health and spread of disease. Availability of fuel for adequate sterilizing of eating utensils and food and the preservation of food proves necessary to promote health. Transportation, which provides access to medical care, shopping, and employment, proves absolutely essential. Hygienic and preventative care, including soap and insecticides, and vitamins and contraceptives, are necessary for maintaining health. Differential access to these life essentials depending on ability to afford with a given income results in differential health.

Gender

Gender can determine health inequity in general health and particular diseases, and is especially magnified in poverty. Socioeconomic inequality is often cited as the fundamental cause for differential health outcomes among men and women. According to the World Health Organization, the health gap between the impoverished and other populations will only be closed if the lives of women are improved and gender inequalities are solved. Therefore, the WHO sees gender empowerment as key in achieving fair distribution of health. The rate at which girls and women die relative to men is higher in low- and middle-income countries than in high-income countries. "Globally, girls missing at birth and deaths from excess female mortality after birth add up to 6 million women a year, 3.9 million below the age of 60. Of the 6 million, one-fifth is never born, one-tenth dies in early childhood, one- fifth in the reproductive years, and two-fifths at older ages. Excess female deaths have persisted and even increased in countries immensely affected by the HIV/AIDS epidemic, like South Africa. In South Africa, excess female mortality between 10 and 50 years of age rose from close to zero to 74,000 deaths per year in 2008. In impoverished populations, there are pronounced differences in the types of illnesses and injuries men and women contract. According to Ward, poor women have more heart disease, diabetes, cancer, and infant mortality. Poor women also have significant comorbidity, or existence of two ailments, such as psychiatric disorders with psychoactive substance use. They are also at greater risk for contracting endemic conditions like tuberculosis, diabetes, and heart disease. Women of low socioeconomic status in urban areas are more liable to contract sexually transmitted diseases and have unplanned pregnancies. Global studies demonstrate that risk for contracting cervical cancer, exclusive to women, increases as socioeconomic status decreases.

Household causes

Health of poor women is impacted by gender inequalities through discriminating distribution of household goods, domestic violence, lack of agency, and unfair distribution of work, leisure, and opportunities between each gender. The way in which resources such as income, nourishment, and emotional support are traded in the household influences women's psychosocial health, nutrition, wellness, access to healthcare services, and threat of violence. The exchange of these elements in a home mediates in the impacts of geographical, cultural, and household patterns that result in inequality in health status and outcomes. Health-related behaviors, access and use of healthcare, stress, and psychosocial resources like social ties, coping, and spirituality all serve as factors that mediate health inequality. Household discrimination causes missing girls at birth, and the persistence of discrimination and poor service delivery perpetuates high female mortality.

Societal causes

Socioeconomic status has long been related to health, those higher in the social hierarchy typically enjoy better health than do those below.

With respect to socioeconomic factors, poor institutions of public health and services can cause worse health in women. According to Moss, components of the geopolitical system that spawn gender and economic inequality, such as history of a nation, geography, policy, services, legal rights, organizations, institutions, and social structures, are all determinants of women's health in poverty. These structures, like socieo-demographic status and culture, norms and sanctions, shape women's productive role in the workplace and reproductive role in the household, which determines health. Women's social capital, gender roles, psychological stress, social resources, healthcare, and behavior form the social, economic, and cultural effects on health outcomes. Also, women facing financial difficulty are more likely to report chronic conditions of health, which occurs often in the lives of the impoverished. Socioeconomic inequality is often cited as the fundamental cause for differential health outcomes among men and women. Differences in socioeconomic status and resulting financial disempowerment for women explain the poorer health and lower healthcare utilization noted among older women compared to men in India, according to a study. According to another study, psycho-social factors also contribute to differences in reported health. First, women might report higher levels of health problems as a result of differential exposure or reduced access to material and social factors that foster health and well-being (Arber & Cooper, 1999). Second, women might report higher health problems because of differential vulnerability to material, behavioral, and psychosocial factors that foster health.

Prenatal and maternal health

Prenatal care also plays a role in the health of women and their children, with excess infant mortality in impoverished populations and nations representing these differentials in health. According to Ward, poverty is the strongest predictor of insufficient prenatal care, which is caused by three factors that reduce access. These include socieodemographic factors (such as age, ethnicity, marital status, and education), systematic barriers, and barriers based on lack of knowledge, attitudes and life-styles. Several studies show the complex associations between poverty and education, employment, teen births, and the health of the mother and child. In 1985, The World Health Organization estimated that maternal mortality rates were 150 times higher in developing countries than developed nations. Furthermore, increased rates of postpartum depression were found in mothers belonging to low socioeconomic status.

Differential health for men

There also exist differentials in health with respect to men. In many post-transition countries, like the Russian Federation, excess female mortality is not a problem, but rather there has been an increase in mortality risks for men. Evidence suggests that excess male mortality correlates with behavior considered socially acceptable among men, including smoking, binge drinking, and risky activities. According to Moss, "Women are more likely to experience role strain and overload that occur when familial responsibilities are combined with occupation-related stress."

Age

Social determinants can have differential effects on health outcomes based on age group.

Youth health

Adolescent health has been proven to be influenced by both structural and proximal determinants, but structural determinants play the more significant role. Structural determinants such as national wealth, income inequality, and access to education have been found to affect adolescent health. Additionally, proximal determinants such as school and household environments are influenced by stratification created by structural determinants, can also affect adolescent health. Access to education was determined to be the most influential structural determinant affecting adolescent health.Proximal determinants include household and community factors, such as household environment, familial relationships, peer relationships, access to adequate food, and opportunities for recreation and activity. The most influential proximal determinant has proven to be family affluence. Family affluence directly affects food security, which correlates with adolescent nutrition and health. Family affluence also influences participation in regular physical activity. While nutrition and physical activity promote physical well-being, both promote psychological health as well. Thus family affluence is correlated with reduced psychological stress during adolescence. Family affluence also affects access to healthcare services; however, in countries with universal healthcare systems, youth belonging to less-affluent households still display poorer health than adolescents from wealthier families. One study (that followed individuals from childhood to adulthood) showed that housing environment impacted mortality, with the main cause of death being the presence of pollutants in the house. Higher rates of chronic diseases such as obesity and diabetes, as well as cigarette smoking were found in adolescents aged 10–21 belonging to low socioeconomic status.

Infant health

Poverty during pregnancy has been reported to cause a wide range of disparities in newborns. Low maternal socioeconomic status has been correlated with low infant birth weight and preterm delivery, physical complications such as ectopic pregnancy, poorer infant physical condition, compromised immune system and increased susceptibility to illness, and prenatal infant death. Sixty percent of children born into poor families have at least one chronic disease. Infant mental complications include delayed cognitive development, poor academic performance, and behavioral problems. Poor women display greater rates of smoking, alcohol consumption, and engagement in risky behaviors. Such risk factors function as stressors that, in combination with social factors such as crowded and unhygienic living environments, financial difficulties, and unemployment, affect fetus health.

Ethnicity

Ethnicity can play an especially large part in determining health outcomes for impoverished minorities. Poverty can overpower race, but within poverty, race highly contributes to health outcomes. African Americans, even in some of the wealthiest cities in the United States, have lower life expectancy at birth than people in much poorer countries like China or India. In the United States, specifically for African American women, as of 2013 for every 100,000 births 43.5 black women would not survive compared to the 12.7 of white women According to studies, black individuals in South Africa suffer worse morbidity and mortality rates due to the limited access to social resources. Poverty is the chief cause of the endemic amounts of disease and hunger and malnutrition among this population. A disproportionate number of cases of the AIDS epidemic in North America are from American minorities, with 72% of women's AIDS cases among Hispanic or African-American women. Among those American minorities, African Americans comprise 12% of the American population yet, made up 45% of new HIV diagnoses. Blacks in American account for the highest proportion of those living with HIV and AIDS in America.

Farmer says the growing mortality differentials between whites and blacks must be attributed to class differentials- which includes recognizing race within impoverished populations. Recognition of race as a determining factor for poor health without recognizing poverty has misled individuals to believe race is the only factor. A 2001 study showed that even with health care insurance, many African Americans and Hispanics lacked a health care provider; the numbers doubled for those without insurance (uninsured: White 12.9%, Black 21.0%, Hispanics 34.3%). With both race and insurance status as obstacles, their health care access and their health suffered.

Health differentials amongst races can also serve as determining factors for other facets of life, including income and marital status. AIDS-affected Hispanic women hold smaller salaries than average women, are part of poorer families, and are more likely to head households. According to one study, black teenage women living in dysfunctional homes were more likely to have serious health issues for themselves or children.

Education

Education plays an especially influential part in the lives of the impoverished. According to Mirowsky and Ross, education determines other factors of livelihood like occupation and income that determines income, which determines health outcomes. Education is a major social determinant of health, with educational attainment related to improved health outcomes, due to its effect on income, employment, and living conditions. Social resources, such as education, determine life expectancy and infant mortality, which measures health. Education has a lasting, continuous, and increasing effect on health. Education is a special determinant of health because it enables people toward self-direction, which leads them to seek goals such as health. Education helps the impoverished develop usable skills, abilities, and resources that help individuals reach goals, including bettering health. Parent's educational level is also important to health, which influences the health of children and the future population. Parent's education level also determines child health, survival, and their educational attainment (Caldwell, 1986; Cleland & Van Ginneken, 1988). "Children born to more educated mothers are less likely to die in infancy and more likely to have higher birth weights and be immunized. Studies in the United States suggest maternal education results in higher parity, greater use of prenatal care, and lower smoking rates, which positively affects child health. An increase in child schooling in Taiwan during the educational reform of 1968 reduced the infant morality rate by 11%, saving 1 infant per 1000 births.

"Fig. 2.1 shows variation between countries in infant mortality from just over 20/1000 live births in Colombia to just over 120 in Mozambique. It also shows inequities within countries – an infant's chances of survival are closely related to her mother's education. In Bolivia, babies born to women with no education have infant mortality greater than 100 per 1000 live births; the infant mortality rate of babies born to mothers with at least secondary education is under 40/1000.All countries included in Fig. 2.1 show the survival disadvantage of children born to women with no education."

Political education and Engagement

Mortality inequalities are produced and reproduced by policies that promotes structural violence for those who are already vulnerable to poverty, while reinforcing the paradigm and the ontological order of power hierarchy. Hence, the political engagement of an individual and their communities play an important factor in determining their access to health care. The Commission on the Social Determinants of Health discusses that explicit commitment to action through multidisciplinary public policies are required for better access to healthcare. One of the recommended action is to expand knowledge and empower the participation of broad segment of society. A manifestation of such action is the mobilization of the population that has been historically oppressed and to raise question about the systemic issues affecting their life. According to WHO, civic participation does not just better physical health, but also mental health status, and overall life quality. History exhibits that when the masses become politically aware of the problems around them, they are more empowered to find their own voice and revolt against systemic inequalities to take control of their lives and improve healthcare accessibility and affordability. On the contrary, nations that do not empower its citizens to be politically educated have way worse health outcomes than nations whose citizens are politically engaged. For instance, there has been a surge in mortality differentials and unwavering decline in health benefits coverage, especially among for the population living under poverty line. As stated in Global Health Promotion, over the last 10 years there has been a steady loss of health coverage for 1 million people every year. Losing health coverage means that an individual could no longer seek affordable treatment or access healthcare, so their health quality would eventually deteriorate. However, if the citizens were to raise their concerns collective to the government, they would have been able to address this systemic factor and subsequently improve their health outcomes.

Occupation

Impoverished workers are more likely to hold part-time jobs, move in and out of work, be migrant workers, or experience stress associated with being unemployed and searching unsuccessfully for unemployment, which all in turn affects health outcomes. According to the World Health Organization, employment and working conditions greatly affect health equity (Kivimaki et al., 2003). This occurs because poor employment conditions exposes individuals to health hazards, which are more likely for low-status jobs. Evidence confirms that high job demand, low control, and low rewards for effort in these low status jobs are risk factors for mental and physical health problems, such as a 50% excess risk of heart disease (Stansfeld & Candy, 2006). The growing power of massive, conglomerate global corporations and institutions to set labor policy and standards agendas has disempowered workers, unions, and the job-seeking by subjecting these individuals to health-damaging working conditions. (EMCONET, 2007). In high- income countries, there has been a growth in job insecurity and precarious employment arrangements (such as informal work, temporary work, part-time work, and piecework), job losses, and a weakening of regulatory protections. Informal work can threaten health through its precarious job instability, lack of regulation to protect working conditions and occupational health and safety. Evidence from the WHO suggests mortality is greater among temporary workers than permanent workers. (Kivimaki et al., 2003). Since most of the global workforce operates under the informal economy, particularly low- and middle-income countries, impoverished populations are greatly affected by these factors.

Socioeconomic and political context

Location

Nation-state/geographical region

Which particular nation an impoverished person lives in deeply affects health outcomes. This can be attributed to governmental, environmental, geographical, and cultural factors. Using life expectancy as a measure of health indicates a difference between countries in likeliness of living to a certain age. Where people are born dramatically impacts their life chances. High-income countries like Japan or Sweden have a life expectancy of 80 years, Brazil-72, India-63. The WHO cites that for rich countries, only 56 (Iceland) to 107 (US) of 1000 adults between 15 and 60 years old will die each year, while Western and Central African countries have adult mortality rates exceeding 300 and 400 of every 1000. The rates are even higher in African nations suffering the AIDS epidemic, such as Zimbabwe where 772 of 1000 adults die each year (WHO 2010). Also, the type of health affliction varies by countries for populations in poverty. Over 80% of cardiovascular disease deaths, that totaled 17.5 million people globally in 2005, occur in low- and middle-income countries. According to the WHO,13500 people die from smoking every day, and soon it will become the leading cause of death in developing countries, just as in high income countries. (Mathers & Loncar, 2005).

Infant and maternal mortality also reveals disparity in health between nations. There exist great inequalities in infant death rates within and between countries, ranging from 20/10000 births in Columbia to 120/10000 in Mozambique. In 1985, The World Health Organization estimated that maternal mortality rates were 150 times higher in developing countries than developed nations.

Urban or rural location

Urban
The location where people live affects their health and life outcomes, which means impoverished people's health outcomes are especially determined by whether they live in a metropolitan area or rural area. In the 19th and 20th century, slums developed in cities and the ensuing crowding, poor sanitation, and inadequate dwellings brought infectious disease and illnesses, causing public health concerns. With the prevalence of inner city ghettos and slums around the globe in cities, with approximately 1 billion people living in slums globally, living situation is an especially strong determinant of health in poverty. Urban areas present health risks through poor living conditions, limited food resources, traffic accidents, and pollution. Urbanization is immensely altering public health problems, particularly for the poor, by directing it towards non-communicable diseases, accidental and violent injuries, and death and health impacts from ecological disaster. (Capbell &Campbell, 2007; Yusuf et al., 2001). Daily living conditions enormously impact health equity too. Equity in living conditions, such as access to quality housing and clean water and hygiene, have been greatly degraded in urban areas by increasing car dependence, land use for roads, inconvenience of non-car transportation, air quality, greenhouse gas emissions, and lack of physical activity (NHF, 2007). The challenges of urban areas, such as high population density, crowding, unsuitable living conditions, and little social support, provide a special challenge to the disabled and populations in low and middle income countries(Frumkin et al., 2004).
  • Obesity: Obesity is a paramount problem, especially among the poor and socially disadvantaged, in cities worldwide, according to the WHO (Hawkes et al., 2007; Friel, Chopra & Satcher, 2007). The increased amount of obesity can be contributed to the nutrition transition that describes how people are now increasingly turning to high-fat, sugar, and salt food sources because of their availability and price. This food transition has fueled the obesity epidemic. This nutrition transition tends to start in cities because of "greater availability, accessibility, and acceptability of bulk purchases, convenience foods, and 'supersized' portions" (Dixon et al., 2007). Physical activity and exercise is strongly determined by the design of cities, including density of homes, heterogeneous land uses, the extent to which streets and sidewalks connect, the walkability, and the provision of and access to local public accommodations and parks for recreation and play. These factors, along with increasing reliance on cars, results in the shift of the population toward physical inactivity, which damages health (Friel, Chopra & Satcher, 2007).
  • Crime: Violence and crime are major urban health challenges. Worldwide, 90% of the 1.6 million annual violent deaths occur in low and middle income counties(WHO, 2002). A large number of deaths and injuries occur because of crime, which affects health.
  • Traffic: Individuals in ghettos and urban areas are the most affected by traffic injuries and vehicle-created air pollution, which causes 800,000 annual deaths due to air pollution, and 1.2 million from traffic accidents. (Roberts & Meddings, 2007; Prüss- Üstün & Corvalán, 2006). This results in greater health risks, like death, for impoverished populations in cities.
  • Mental illness: Living in a ghetto increases the likelihood of developing a mental illness, especially in children. People in this environment are less likely to receive effective mental health services. Children exposed to ongoing poverty, present in a ghetto, present a high level of depression, anxiety, social withdrawal, peer conflict and aggression. Mental health symptoms are increased in the ghetto due to exposure to community crime, gang induced violence, neighborhood drug infestations, and substandard housing conditions.
  • Other: In the United States, HIV is more prevalent in cities along the east coast, with prevalence among African-American women in cities 5 to 15 times higher than for women in all areas of that state. "Inner-city women are the most likely of all in the United States to birth dead or extremely sick babies, partially because the massive erosion of prenatal care availability in their area. Slums, made up exclusively of extremely poor populations, provide a particularly strong threat for poor health. Child mortality in the slums of Nairobi, which 60% of the population inhabits, is 2.5 times greater than in other areas of the city. In the slums of Manila, 39% of children have TB, which is twice the national average. The term ‘housing instability’ describes a condition in which people have been or will be homeless in the future. People facing such instability have poorer health care access and more acute health problems than the rest of the population. A city populations grew and rents rose, those receiving Section 9 housing vouchers could no longer afford the rising rents and were forced to move away.
Rural
Living in a rural community, whether in the United States, or around the globe, reduces access to medical services, health insurance, and changes health culture. Differentials exist between rural and urban communities, and some health disadvantages exist for impoverished rural residents. Since health of a population increases in geographical locations that have a higher prevalence of primary care physicians, rural areas face worse health. According to certain studies, measures of health and well-being indicate that rural populations have worse health outcomes. Rural residents have a greater rate of premature mortality (less than age 75 at death) than urban residents. According to certain studies in the United States, the death rate of individuals age 1–24 years was 31% higher than those in urban counties. The death rate of adults 25 to 64 years old was 32% higher among rural residents than those of suburban counties and of urban counties. These higher death rates were contributed to unintentional injuries, suicide, and chronic obstructive pulmonary disease. In 1997 in the United States, 18% of adults in rural areas had chronic health conditions, compared to only 13% of suburban adults. The National Health Interview Survey indicated that in 1998, 16% of rural adults reported poor health. Poor rural residents have only 21% Medicaid coverage, while poor urban populations report 30% coverage. Demographic and socioeconomic factors vary between rural and urban areas, which contributes to some health disparities. For extremely poor rural communities, variables in the community, like ecological setting, including climate, soil, rainfall, temperature, altitude, and seasonality greatly impact health. "In rural subsistence societies, these variables can have strong influence on child survival by affecting the quantity and variety of food crops produced, the availability and quality of water, vector-borne disease transmission"

Governance/policy

Type and structure of governments and their social and economic policy more deeply affects the health of the impoverished than other populations. Every component of government- from finance, education, housing, employment, transportation, and health policy- affects population health and health equity. Life expectancy variation between countries can be partially attributed to the type of political regime, whether that be fascist, communist, conservative, or social-democratic. However, changing the status of government regime does not always end the type of policies in place, as seen in South Africa. The end of South Africa's apartheid regime has still not dismantled the structures of inequality and oppression, which has led the persistent social inequality to perpetuate the spread of HIV, diminishing population health. Also, the political economy, encompassing production organization, physical infrastructure, and political institutions play a large role in determining health inequalities.

Social service and healthcare availability

health care source

Impoverished people depend on healthcare and other social services to be provided in the social safety net, therefore availability greatly determines health outcomes. Since low living standards greatly influence health inequity, generous social protection systems result in greater population health, with lower mortality rates, especially in disadvantaged populations. A successful example of such social service program is the Senior Companion program, an extension of the United States federal program Senior Corps. The program provides assistance for adults who have physical and mental disadvantages. It pairs up senior volunteers with patients who come from low-income background to help them increase their social capability, ability to live independently and more accessibility to healthcare. A mixed-method study explores that the program does target various social determinants of health and have positive effects on enrolled elders' health status (although less positive correlation long-term). It concludes that the program does have enthusiastic impacts on clients and volunteers' overall wellness. The result is homogeneous with conclusions from other studies, with emerging themes include: companionship, reduced depression, access to healthcare, isolation, and increased social network.

Nations that have more generous social protection systems have better population health (Lundberg et al., 2007). More generous family policies correlate with lower infant mortality. Nations that offered higher coverage and reimbursement for pensions and sickness, unemployment, and employment accident insurance have a higher LEB (Lundberg et al., 2007), as well as countries with more liberal pensions have less senior mortality. (Lundberg et al., 2007)

Healthcare

The health care system represents a social determinant of health as well as it influences other determining factors. People's access to health care, their experiences there, and the benefits they gain are closely related to other social determinants of health like income, gender, education, ethnicity, occupation, and more. For poor people, systematic barriers in the social structure are formidable, especially financing. Medicaid and maternity coverage structures have complex and time-consuming registration processes, along with long waits and unsure eligibility. A study of the Emergency Department found that the majority of patients presenting with mental illness were those on Medical (20.4%) and Medicare (31.5%), whereas only 12.4% of privately insured patients presented with mental illness. California has expanded its eligibility of Medi-Cal under federal law to cover as many people as possible. Inequalities in health are also determined by these socioeconomic and cultural factors. Health care is inequitably distributed globally, with pronounced inequality for the poor in low- and middle-income countries. One study demonstrated that doctors treat poor populations differently, showing that disadvantaged patients are less likely to receive the recommended diabetic treatments and are more likely to undergo hospitalization due to the complications of diabetes (Agency for Health Care Research and Quality, 2003). According to the WHO, healthcare systems can most improve health equality when institutions are organized to provide universal coverage, where everyone receives the same quality healthcare regardless of ability to pay, as well as a Primary Healthcare system rather than emergency center assistance.

These structural problems result in worse healthcare and therefore worse health outcomes for impoverished populations. Health care costs can pose absolutely serious threats to impoverished populations, especially in countries without proper social provisions. According to US HHS, "In 2009, children 6–17 years of age were more likely to be uninsured than younger children, and children with a family income below 200% of the poverty level were more likely to be uninsured than children in higher-income families." In elderly populations, individuals below 400% of the poverty line were between 3 and 5 times more likely to lack insurance. Children below 200% of the poverty line were also less likely to have insurance than wealthier families. Also, in 2009 in the US, 20% of adults (ages 18–64) below 200% of the poverty line did not receive their necessary drugs because of cost, compared to only 4% of those above 400% of the poverty line. Increasing healthcare costs (including higher premiums) imposed a burden on consumers. In 2010, President Obama introduced the Patient Protection and Affordable Care Act (ACA), expanding health care to many that lacked coverage. The U.S. had the highest rate of uninsured people, and the highest health care costs, of all industrialized nations at the time. The ACA helped 20 million Americans get coverage and decreased the rates of uninsured from 16% in 2010 to 8.6% in 2016. The ACA brought coverage to people who had suffered from downgrades in Employee Insurance programs, by providing a health insurance marketplace, giving them access to private insurance plans along with income-based government subsidies. This can be seen in other nations, where in Asia, payments for healthcare pushed almost 3% of the population of 11 countries below 1 US$ per day.

Societal psychological influences

In impoverished communities, different social norms and stressors exist than in other populations, which can greatly affect health outcomes in disadvantaged populations. According to the National Institutes of Health, "low socioeconomic status may result in poor physical and/or mental health ... through various psychosocial mechanisms such as poor or 'risky' health-related behaviors, social exclusion, prolonged and/ or heightened stress, loss of sense of control, and low self-esteem as well as through differential access to proper nutrition and to health and social services (National Institutes of Health 1998)." These stressors can cause physiological alterations including increased cortisol, changed blood-pressure, and reduced immunity which increases their risks for poor health.

Structural violence

Underlying social structures that propagate and perpetuate poverty and suffering- structural violence- majorly determine health outcomes of impoverished populations. Poor and unequal living conditions result from deeper structural conditions, including "poor social policies and programs, unfair economic arrangements, and bad politics," that determine the way societies are organized. The structure of the global system causes inequality and systematic suffering of higher death rates, which is caused by inequity in distribution of opportunities and resources, which is termed structural violence.

Definition

Structural violence is a term devised by Johan Galtung and liberation theologians during the 1960s to describe economic, political, legal, religious, and cultural social structures that harm and inhibit individuals, groups, and societies from reaching their full potential. Structural violence is structural because the causes of misery are "embedded in the political and economic organization of our social world; they are violent because they cause injury to people." Structural violence is different from personal or behavioral violence because it exclusively refers to preventable harm done to people by no one clear individual, but arises from unequal distribution of power and resources, pre-built into social structure. Structural violence broadly includes all kinds of violations of human dignity: absolute and relative poverty, social inequalities like gender inequality and racism, and outright displays of human rights violations. The idea of structural violence is as old as the study of conflict and violence, and so it can also be understood as related to social injustice and oppression.

Effects

Structural violence is often embedded in longstanding social structures, ubiquitous throughout the globe, that are regularized by persistent institutions and regular experience with them. These social structures seem so normal in our understanding of the world that they are almost invisible, but inequality in resource access, political power, education, healthcare, and legal standing are all possible perpetrators of structural violence. Non citizens do not have access to medical insurance and healthcare and must seek care in clinics and outpatient departments. Structural violence occurs "whenever persons are harmed, maimed, or killed by poverty and unjust social, political, and economic institutions, systems, or structures" Structural violence can contribute to worse health outcomes through either harming or killing victims, just like armed violence can have these effects. This type of unintended harm perpetuated by structural violence progressively promotes misery and hunger that eventually results in death, among other effects. Ehrlich and Ehrlich reported in 1970 that between 10 and 20 million of the 60 million annual deaths across the globe result from starvation and malnutrition. Their report also estimated that structural violence was responsible for the end of one billion lives between 1948 and 1967 in the third world.

Structural violence connection to health

Inequality in daily living conditions stem from unseen social structures and practices. This systematic inequality is produced by social norms, policies, and practices that promote the unfair distribution of power, wealth, and other social resources, such as healthcare. "The poor health of the poor, the social gradient in health within countries, and the marked health inequities between countries are caused by the unequal distribution of power, income, goods, and services, globally and nationally." First, structural violence is often a major determinant of the distribution and outcome of disease. It has been known for decades that epidemic disease is caused by structural forces. Structural violence can affect disease progression, such as in HIV, where harmful social structures profoundly affect diagnosis, staging, and treatment of HIV and associated illnesses. The determinants of disease and their outcome are set by the social factors, usually rampant with structural violence, that determine risk to be infected with the disease. Understanding how structural violence is embodied at the community, individual, and microbial levels is vital to understanding the dynamics of disease. The consequences of structural violence is post pronounced in the world's poorest countries and greatly affects the provision of clinical services in these countries. Elements of structural violence such as "social upheaval, poverty, and gender inequality decrease the effectiveness of distal services and of prevention efforts" presents barriers to medical care in countries like Rwanda and Haiti Due to structural violence, there exists a growing outcome gap where some countries have access to interventions and treatment, and countries in poverty who are neglected. With the power of improved distal interventions, the only way to close this outcome gap between countries who do and do not have access to effective treatment, lies on proximal interventions to reduce the factors contributing to health problems that arise from structural violence.
