CENTER ON SOCIAL DISPARITIES IN HEALTH University of California, San Francisco What are “health inequalities”? Differences, variations: descriptive terms Most official U.S.A. definitions refer only to differences between unspecified groups But we really mean: Health differences that are unfair (in a particular way) Whitehead: unfair, avoidable, and unjust But notions of fairness, avoidability, and justice vary
CENTER ON SOCIAL DISPARITIES IN HEALTH University of California, San Francisco Are all health differences unfair? Many women have obstetric problems; men do not Arm/leg fractures more likely in skiers than non-skiers Wealthy people in Manhattan have some health problems that wealthy people in Hollywood do not Younger adults are generally healthier than the elderly Some claim that any avoidable health difference is unfair Who determines what is avoidable?
CENTER ON SOCIAL DISPARITIES IN HEALTH University of California, San Francisco What if the causes are not known? to have low birth weight to be born prematurely which predict infant mortality, childhood disability and development, and adult chronic disease The causes are not known Can we call it unfair? In the USA, compared with European-American (“White”) newborns, African-American (“Black”) newborns are 2 to 3 times as likely:
CENTER ON SOCIAL DISPARITIES IN HEALTH University of California, San Francisco Other challenges: Which groups? The U.S. National Institutes of Health (NIH) has a new institute on minority health and health disparities (NIMHD). Should NIMHD prioritize health of: Veterans? People with autism? People with rare but catastrophic diseases? Higher incidence of breast cancer among White women? Shorter life expectancy among men?
CENTER ON SOCIAL DISPARITIES IN HEALTH University of California, San Francisco Other challenges: Individuals v. groups A few researchers (then in leadership roles at WHO) once proposed that health inequalities should not be measured by comparing health of pre-selected social groups, e.g., rich - poor Because it pre-judges causality, obstructing comprehensive inquiry into causes Their approach: compare individuals (not groups) on health only, then seek explanatory variables During their tenure, WHO ended an initiative providing technical assistance to countries to collect & analyze health data according to markers of social position Removed fairness & justice from the agenda for health monitoring
CENTER ON SOCIAL DISPARITIES IN HEALTH University of California, San Francisco Other challenges: the reference group for a health equity comparison Some propose using the average as the reference group, or the healthiest, regardless of their social characteristics Active dispute now in some U.S. public health agencies What is wrong with using the population average –or the healthiest-- as the reference group? Average underestimates inequalities where a higher % of population are disadvantaged Many reasons –including biologic--for healthiest group to be healthiest
CENTER ON SOCIAL DISPARITIES IN HEALTH University of California, San Francisco Human rights principles provide guidance to address these challenges The right to achieve the highest attainable standard of health Rights to: education, living standard adequate for health, benefits of progress All rights are inter-connected and indivisible Ratifying human rights agreements obligates governments to progressively remove obstacles to realizing all rights Particularly for groups who have more obstacles
CENTER ON SOCIAL DISPARITIES IN HEALTH University of California, San Francisco Relevant human rights principles, e.g.: Non-discrimination and equality All persons have equal rights and should be able to realize all their rights without discrimination Including de facto (unconscious, institutional) discrimination – not just deliberate, inter-personal Prohibit policies with either intent or effect of discrimination Affirmative action is needed to achieve equal rights for vulnerable groups
CENTER ON SOCIAL DISPARITIES IN HEALTH University of California, San Francisco Human rights principles: Non-discrimination and equality Specifies vulnerable groups: defined by race or ethnic group, skin color, religion, language, or nationality; socioeconomic resources or position; gender, sexual orientation or gender identity; age; physical, mental, or emotional disability or illness; geography; political or other affiliation Implicit: vulnerability due to history of discrimination or marginalization, lower social position
A rights-based definition of health inequality A health difference closely linked with social or economic disadvantage Health disparities adversely affect groups of people who have systematically experienced greater social or economic obstacles to health based on their racial or ethnic group; religion; socioeconomic status; gender; mental health; cognitive, sensory, or physical disability; sexual orientation or gender identity; or other characteristics historically linked to discrimination or exclusion
A rights-based definition of health inequalities Not all health differences -- or even all health differences warranting attention A particular subset of health differences that reflect social injustice Plausibly avoidable, systematic health differences adversely affecting a socially disadvantaged group May reflect social disadvantage – but in any case put already disadvantaged groups at further disadvantage with respect to their health
CENTER ON SOCIAL DISPARITIES IN HEALTH University of California, San Francisco Challenges addressed: Burden of proof regarding causation The causes of many important health inequalities (e.g., racial disparities in low birth weight, premature birth or in stage-specific breast cancer survival) are unknown Regardless of causes, health inequalities are unfair because they put already disadvantaged groups at further disadvantage on health Health inequalities are further obstacles to achieving rights
CENTER ON SOCIAL DISPARITIES IN HEALTH University of California, San Francisco Challenges addressed: Groups or individuals? Which groups? Compare groups with different levels of social advantage: resources, power, prestige/acceptance Human rights principles define the groups Racial/ethnic, religious, or tribal Socioeconomic (income/wealth, education, occupation) Gender, gender identity, sexual orientation, age, mental or physical disability/illness, geographic Implicit: groups that have historically experienced discrimination or marginalization Appropriate groups verifiable based on evidence of wealth, power (e.g., high political/executive office), social inclusion (e.g., hate crime victims).
CENTER ON SOCIAL DISPARITIES IN HEALTH University of California, San Francisco Measurement challenges: The reference group The most socially privileged group (greatest power, wealth, prestige), e.g., High income/wealthy individuals, households, or neighborhoods Most privileged racial/ethnic group Indicates what should be possible for all groups (the “highest attainable standard of health”) The population average is too low a standard, especially where large proportions are disadvantaged The healthiest group may be healthiest for reasons not reflecting social justice
CENTER ON SOCIAL DISPARITIES IN HEALTH University of California, San Francisco Contributions of a human rights framework Addresses de facto discrimination/exclusion Sets benchmark at highest attainable standard of health Entitlement v. charity Addresses multiple dimensions of material and social deprivation and disadvantage Poverty as well as race-based and other discrimination and their physical and psychosocial consequences Supports addressing inequalities in social determinants of health (rights to education, living standard adequate for health, social participation…) Reflects global consensus on values and concepts
CENTER ON SOCIAL DISPARITIES IN HEALTH University of California, San Francisco Concepts and measurement of health inequalities and health equity: not just a technical issue Based on values Equity is the ethical principle underlying a commitment to reduce inequalities Health inequalities are the metric by which health equity is assessed Human rights principles can guide analysis, measurement, and action Implications for policy agendas, resource allocation, & accountability Inherently political
