Immigration and Health • Hispanics and Asian Americans tend to have equivalent

or better health status than whites

• Immigrants of all racial/ethnic groups tend to have better health than their native born counterparts

• With length of stay in the U.S., the health advantage of immigrants declines

• Latinos and Asians differ markedly in their levels of human capital upon arrival in the U.S.

• Given the low SES profile of Hispanic immigrants and their ongoing difficulties with educational and occupational opportunities, the health of Latinos is likely to decline more rapidly than that of Asians and

to be worse than the U.S. average in the future

Challenges

What are the relevant factors and what is the relative contribution of each to shaping the relationship between migration status/generational status and health for racial/ethnic minority populations?

What interventions, if any, can reverse the downward health trajectory of immigrants with length of stay in the U.S.?

The Persistence of Racial Disparities

• We have FAILED! • In spite of:

-- a War on Poverty-- a Civil Rights revolution-- Medicare & Medicaid-- the Hill-Burton Act-- Major advances in medical research &

technology We have made little progress in reducing the elevated

death rates of blacks and American Indians relative to whites.

SES: A Key Determinant of Heath

• Socioeconomic Status (SES) usually measured by income, education, or occupation influences health in virtually every society.

• SES is one of the most powerful predictors of health, more powerful than genetics, exposure to carcinogens, and even smoking.

• The gap in all-cause mortality between high and low SES persons is larger than the gap between smokers and non-smokers.

• Americans who have not graduated from high school have a death rate two to three times higher than those who have graduated from college.

• Low SES adults have levels of illness in their 30s and 40s that are not seen in the highest SES group until after the ages of 65-75.

Added Burden of Race

• Race and SES reflect two related but not interchangeable systems of inequality

• SES accounts for a large part of the racial differences in health

• BUT, there is an added burden of race, over and above SES that is linked to poor health.

Why Race Still Matters1. All indicators of SES are non-equivalent across race.

Compared to whites, blacks receive less income at the same levels of education, have less wealth at the equivalent income levels, and have less purchasing power (at a given level of income) because of higher costs of goods and services.

2. Health is affected not only by current SES but by exposure to social and economic adversity over the life course.

3. Personal experiences of discrimination and institutional racism are added pathogenic factors that can affect the health of minority group members in multiple ways.

Race and Economic Hardship 1995African Americans were more likely than whites to experience the following hardships 1:

1. Unable to meet essential expenses

2. Unable to pay full rent on mortgage

3. Unable to pay full utility bill

4. Had utilities shut off

5. Had telephone shut off

6. Evicted from apartment1 After adjustment for income, education, employment status, transfer payments, home ownership, gender, marital status, children, disability, health insurance and residential mobility.

Bauman 1998; SIPP

Page 28: Dr David Williams on Health Disparities

Racism: Potential Mechanisms• Institutional discrimination can restrict economic

attainment and thus differences in SES and health.• Segregation creates pathogenic residential

conditions.• Discrimination can lead to reduced access to

desirable goods and services.• Internalized racism (acceptance of society’s

negative beliefs) can adversely affect health.• Racism can lead to increased exposure to

traditional stressors (e.g. unemployment). • Experiences of discrimination may be a neglected

psychosocial stressor.

Discrimination Persists

• Pairs of young, well-groomed, well-spoken college men with identical resumes apply for 350 advertised entry-level jobs in Milwaukee, Wisconsin. Two teams were black and two were white. In each team, one said that he had served an 18-month prison sentence for cocaine possession.

• The study found that it was easier for a white male with a felony conviction to get a job than a black male whose record was clean.

Every Day DiscriminationIn your day-to-day life how often do the following things happen to

you?• You are treated with less courtesy than other people.• You are treated with less respect than other people.• You receive poorer service than other people at restaurants or

stores.• People act as if they think you are not smart.• People act as if they are afraid of you.• People act as if they think you are dishonest.• People act as if they’re better than you are.• You are called names or insulted.• You are threatened or harassed.

Everyday Discrimination and Subclinical Disease

In the study of Women’s Health Across the Nation (SWAN):

-- Everyday Discrimination was positively related to subclinical carotid artery disease (IMT; intima-media thickness) for black but not white women

-- chronic exposure to discrimination over 5 years was positively related to coronary artery calcification (CAC)

Arab American Birth Outcomes

• Well-documented increase in discrimination and harassment of Arab Americans after 9/11/2001

• Arab American women in California had an increased risk of low birthweight and preterm birth in the 6 months after Sept. 11 compared to pre-Sept. 11

• Other women in California had no change in birth outcome risk pre-and post-September 11

differences in: -- self-reported physical and/or mental health in the

U.S. (Williams et al, 1997; Ren et al, 1999; Pole et al, 2005), Australia (Larson et al, 2007), South Africa (Williams et al. 2008) & New Zealand (Harris et al. 2006)

-- birth outcomes (Mustillo et al. 2004) -- health care trust (Adegmembo et al, 2006) -- sleep quality and physical fatigue (Thomas et al.

2006)

Page 38: Dr David Williams on Health Disparities

Discrimination and Health Behaviors

Recent studies indicate that experiences of discrimination are associated with:

• Delays in seeking treatment

• Lower adherence to treatment regimes

• Lower rates of follow-up

• Poorer perceived quality of care

• Alcohol, tobacco and other drug use

Van Houteven et al. 2005, Banks & Dracup, 2006; Wagner & Abbott 2007; Wamala et al. 2007

Page 39: Dr David Williams on Health Disparities

Policy Area: Stress & Resources

Social status determines the types of stressors and level of exposure to stressors for social groups, as well as, the availability (and efficacy?) of resources to cope with stress

Page 40: Dr David Williams on Health Disparities

Stress and Health

• Stressors can lead to altered functioning of neuroendocrine and other pathways that can adversely affect health.

• Stressors and the negative emotional states created by them can lead to health behaviors such as impaired sleep patterns, decreased physical activity, increased substance use and food consumption that all increase risk of chronic disease.

The Effect of Race and Sex on Physicians'Recommendations for Cardiac Catheterization

• 720 physicians viewed recorded interviews

• Reviewed data about a hypothetical patient

• The physicians then made recommendations about that patient's care

Page 44: Dr David Williams on Health Disparities

The Effect of Race and Sex on Physicians'Recommendations for Cardiac Catheterization

• Women (OR =0.60) and blacks (OR =0.60) were less likely to be referred for cardiac catheterization than men and whites, respectively.

• Black women were significantly less likely to be referred for catheterization than white men (OR= 0.4)

Schulman et. al., NEJM 1999;340:618.

Page 45: Dr David Williams on Health Disparities

STUDY CHARGE • Assess the extent of racial and ethnic differences in healthcare that are not otherwise attributable to known factors such as access to care (e.g., ability to pay or insurance coverage);

• Evaluate potential sources of racial and ethnic disparities in healthcare, including the role of bias, discrimination, and stereotyping at the individual (provider and patient), institutional, and health system levels; and,

• Provide recommendations regarding interventions to eliminate healthcare disparities.

Page 48: Dr David Williams on Health Disparities

Race and Medical Care

• Across virtually every therapeutic intervention, ranging from high technology procedures to the most elementary forms of diagnostic and treatment interventions, minorities receive fewer procedures and poorer quality medical care than whites.

• These differences persist even after differences in health insurance, SES, stage and severity of disease, co-morbidity, and the type of medical facility are taken into account.

• Moreover, they persist in contexts such as Medicare and the VA Health System, where differences in economic status and insurance coverage are minimized.

Ethnicity and AnalgesiaChart review of 139 patients with isolated long-bone

fracture at UCLA Emergency Department (ED):• All patients aged 15 to 55, had the injury within 6

hours of ER visit, had no alcohol intoxication.• 55% of Hispanics received no analgesic compared

to 26% of non-Hispanic whites.• Simultaneous adjustment for sex, primary language,

insurance status, occupational injury, time of presentation, total time in ED, fracture reduction and hospital admission, Hispanic ethnicity was the strongest predictor of no analgesia.

• After adjustment for all factors, Hispanics were 7.5 times more likely than non-Hispanic whites to receive no analgesia.

Reducing Inequalities -IHealth Care

• Improve access to care and the quality of care– Give emphasis to the prevention of illness– Provide effective treatment– Develop incentives to reduce inequalities in the

quality of care

Page 51: Dr David Williams on Health Disparities

Care that Addresses the Social context

• Effective health care delivery must take the socio-economic context of the patient’s life seriously

• The health problems of vulnerable groups must be understood within the larger context of their lives

• The delivery of health services must address the many challenges that they face

• Taking the special characteristics and needs of vulnerable populations into account is crucial to the effective delivery of health care services.

• This will involve consideration of extra-therapeutic change factors: the strengths of the client, the support and barriers in the client’s environment and the non-medical resources that may be mobilized to assist the client

Nurse Family Partnership• Nurses make prenatal and postnatal visits to pregnant

women.• Nurses enhance parents’ economic self-sufficiency by

addressing vision for future, subsequent pregnancies, educational and job opportunities.

• Three randomized control trials (Elmira, NY; Memphis, TN; Denver, CO)

• Improved prenatal behaviors, pregnancy outcomes, maternal employment, relationships with partner.

• Reduces child abuse and neglect, subsequent pregnancies, welfare and food stamp use

• $17,000 return to society for each family served

Olds 2002, Prevention Science

Page 53: Dr David Williams on Health Disparities

Needed Interventions

Policies to reduce inequalities in health must also address fundamental non-

medical determinants.

Page 54: Dr David Williams on Health Disparities

Guiding Principles

1. Health Policy must be re-defined to include policies in all sectors of society that have health consequences.

2. Policies which improve average health may have no impact on social inequalities in health.

3. We need policies that improve health overall and targeted interventions to address social inequalities.

4. Major gains are possible through strategies that tackle health problems that occur most frequently.

5. Families with children should be a priority.

Page 55: Dr David Williams on Health Disparities

Needed Behavioral Changes

• Reducing Smoking

• Improving Nutrition and Reducing Obesity

• Increasing Exercise

• Reducing Alcohol Misuse

• Improving Sexual Health

• Improving Mental Health

Page 56: Dr David Williams on Health Disparities

Reducing Inequalities IReducing Negative Health Behaviors?

*Changing health behaviors requires more than just more health information. “Just say No” is not enough.

*Interventions narrowly focused on health behaviors are unlikely to be effective.

*The experience of the last 100 years suggests that interventions on intermediary risk factors will have limited success in reducing social inequalities in health as long as the more fundamental social inequalities themselves remain intact.

House & Williams 2000; Lantz et al. 1998; Lantz et al. 2000

Page 57: Dr David Williams on Health Disparities

Changes in Smoking Over Time -I

Successful interventions require a coordinated and comprehensive approach:

• The active involvement of professionals and volunteers from many organizations (government, health professional organizations, community agencies and businesses)• The use of multiple intervention channels (media, workplaces, schools, churches, medical and health societies)

Warner 2000

Page 58: Dr David Williams on Health Disparities

Changes in Smoking Over Time -2

The use of multiple interventions – • Efforts to inform the public about the dangers of cigarette smoking (smoking cessation programs, warning labels on cigarette packs)• Economic inducements to avoid tobacco use (excise taxes, differential life insurance rates)• Laws and regulations restricting tobacco use (clean indoor air laws, restricting smoking in public places and restricting sales to minors)

Even with all of these initiatives, success has been only partial

Warner 2000

Page 59: Dr David Williams on Health Disparities

Moving Upstream

Effective Policies to reduce inequalities in health must address fundamental

non-medical determinants.

Page 60: Dr David Williams on Health Disparities

WHY?

WHY?

WHY?

Page 61: Dr David Williams on Health Disparities

Centrality of the Social Environment

An individual’s chances of getting sick are largely unrelated to the receipt of medical care

Where we live, learn, work, play and worship determine our opportunities and chances for being healthy

Social Policies can make it easier or harder to make healthy choices

Page 62: Dr David Williams on Health Disparities

SES and Health Risks

SES is linked to:

*Exposures to health enhancing resources *Exposures to health damaging factors *Exposure to particular stressors *Availability of resources to cope with stress

Health practices (smoking, poor nutrition, drinking, exercise, etc.) are all socially patterned

Page 63: Dr David Williams on Health Disparities

Making Healthy Choices Easier

Factors that facilitate opportunities for health:

• Facilities and Resources in Local Neighborhoods

• Socioeconomic Resources

• A Sense of Security and Hope

• Exposure to Physical, Chemical, & Psychosocial Stressors

• Psychological, Social & Material Resources to Cope with Stress

Page 64: Dr David Williams on Health Disparities

Redefining Health Policy

Health Policies include policies in all sectors of society that affect opportunities to choose health, including, for example,

• Housing Policy

• Employment Policies

• Community Development Policies

• Income Support Policies

• Transportation Policies

• Environmental Policies

Page 65: Dr David Williams on Health Disparities

Policy Implications

Since the socio-political environment and SES is a key determinant of health,

improving social and economic conditions is critical to improving health

and reducing health disparities

Page 66: Dr David Williams on Health Disparities

Policy Area

Place Matters!

Geographic location determines exposure to risk factors and resources

that affect health.

Page 67: Dr David Williams on Health Disparities

Racial Segregation Is …1. …"basic" to understanding racial inequality in

America (Myrdal 1944) .

2. …key to understanding racial inequality (Kenneth Clark, 1965) .

3. …the "linchpin" of U.S. race relations and the source of the large and growing racial inequality in SES (Kerner Commission, 1968) .

4. …"one of the most successful political ideologies" of the last century and "the dominant system of racial regulation and control" in the U.S (John Cell, 1982).

5. …"the key structural factor for the perpetuation of Black poverty in the U.S." and the "missing link" in efforts to understand urban poverty (Massey and Denton, 1993).

Page 68: Dr David Williams on Health Disparities

How Segregation Can Affect Health

1. Segregation determines quality of education and employment opportunities.

2. Segregation can create pathogenic neighborhood and housing conditions.

3. Conditions linked to segregation can constrain the practice of health behaviors and encourage unhealthy ones.

Segregation: Distinctive for Blacks• Blacks are more segregated than any other

racial/ethnic group.

• Segregation is inversely related to income for Latinos and Asians, but is high at all levels of income for blacks.

• The most affluent blacks (income over $50,000) are more highly segregated than the poorest Latinos and Asians (incomes under $15,000).

• Thus, middle class blacks live in poorer areas than whites of similar SES and poor whites live in much better neighborhoods than poor blacks.

• African Americans manifest a higher preference for residing in integrated areas than any other group.

Residential Segregation and SES

A study of the effects of segregation on young African American adults found that the elimination of segregation would erase black-white differences in

Racial Differences in Residential Environment

• In the 171 largest cities in the U.S., there is not even one city where whites live in ecological equality to blacks in terms of poverty rates or rates of single-parent households.

• “The worst urban context in which whites reside is considerably better than the average context of black communities.” p.41

Reducing Inequalities IIAddress Underlying Determinants of Health

• Improve conditions of work, re-design workplaces to reduce injuries and job stress

• Enrich the quality of neighborhood environments and increase economic development in poor areas

• Improve housing quality and the safety of neighborhood environments

Page 75: Dr David Williams on Health Disparities

Improving Residential Circumstances

Policies to reduce racial disparities in SES and health should address the concentration of economic disadvantage and the lack of an infrastructure that promotes opportunity that co-occurs with segregation and exists on many American Indian reservations.

That is, eliminating the negative effects of segregation on SES and health requires a major infusion of economic capital to improve the social, physical, and economic infrastructure of disadvantaged communities.

Neighborhood Renewal and Health - I

• A 10-year follow-up study of residents in 5 neighborhood types in Norway found that changes in neighborhood quality were associated with improved health.

• The neighborhood improvements: a new public school, playground extensions, a new shopping center with restaurants and a cinema, a subway line extension into the neighborhood, a new sports arena & park, and organized sports activities for adolescents.

• Residents of the area that had experienced these dramatic improvements in its social environment reported improved mental health 10 years later

• This effect was not explained by selective migration

Dalgard and Tambs 1997

Page 77: Dr David Williams on Health Disparities

Neighborhood Renewal and Health - II

• Neighborhood improvement in a poorly functioning area in England was linked to improved health and social interaction.

• Improvements: housing was refurbished (made safe & sheltered from strangers), traffic regulations improved, improved lighting & strengthening of windows, enclosed gardens for apartments, closed alleyways, and landscaping. Residents involved in planning process.

• One year later:

– Levels of optimism, belief in the future, identification with their neighborhood, trust in other neighbors, and contact between the neighbors had all increased.

– Symptoms of anxiety and depression had declined.

Halpern, 1995

Page 78: Dr David Williams on Health Disparities

Neighborhood Change and Health

• The Moving to Opportunity Program randomized families with children in high poverty neighborhoods to move to less poor neighborhoods.

• It found, three years later, that there were improvements in the mental health of both parents and sons who moved to the low-poverty neighborhoods.

Leventhal and Brooks-Gunn, 2003

Reducing Inequalities IIIAddress Underlying Determinants of Health

• Improve living standards for poor persons and households

• Increase access to employment opportunities

• Increase education and training that provide basic skills for the unskilled and better job ladders for the least skilled

• Invest in improved educational quality in the early years and reduce educational failure

Page 80: Dr David Williams on Health Disparities

Increased Income and Health

• A study conducted in the early 1970s found that mothers in the experimental income group who received expanded income support had infants with higher birth weight than that of mothers in the control group.

• Neither group experienced any experimental manipulation of health services.

• Improved nutrition, probably a result of the income manipulation, appeared to have been the key intervening factor.

Kehrer and Wolin, 1979

Page 81: Dr David Williams on Health Disparities

Income Change and Health

• A natural experiment assessed the impact of an income supplement on the mental health of American Indian children.

• It found that increased family income (because of the opening of a casino) was associated with declining rates of deviant and aggressive behavior.

Costello et al. 2003

Health Effects of Civil Rights Policy• Civil Rights policies narrowed black-white economic gap

• Black women had larger gains in life expectancy during 1965 - 74 than other groups (3 times as large as those in the decade before)

• Between 1968 and 1978, black males and females, aged 35-74, had larger absolute and relative declines in mortality than whites

• Black women born 1967 - 69 had lower risk factor rates as adults and were less likely to have infants with low-birth weight and low APGAR scores than those born 1961- 63

• Desegregation of Southern hospitals enabled 5,000 to 7,000 additional Black babies to survive infancy between 1965 to 1975

Early Life

• Brain circuits in fetal and early childhood periods are affected by exposure to stress

• Toxic stress during this period, such as poverty, abuse, or parental depression, can adversely affect brain architecture and lead to elevated levels of cortisol and adrenaline

• When stress hormones are activated too often and for too long, they can damage the hippocampus

• This can lead to impairments in learning, memory and the ability to regulate stress responses

Family Structure and SES

Compared to children raised by 2 parents those raised by a single parent are more likely to:

• grow up poor• drop out of high school• be unemployed in young adulthood• not enroll in college • have an elevated risk of juvenile delinquency and

participation in violent crime.

McLanahan & Sandefur 1994; Sampson 1987

Page 93: Dr David Williams on Health Disparities

• Economic marginalization of males (high unemployment & low wage rates) is the central determinant of high rates of female-headed households.

• Marriage rates are positively related to average male earnings.

• Marriage rates are inversely related to male unemployment.

Page 98: Dr David Williams on Health Disparities

High/Scope Perry Preschool 123 young African-American children, living in poverty

and at risk of school failure.

Randomly assigned to initially similar program and no-

program groups.

4 teachers with bachelors’ degrees held a daily class of 20-

25 three- and four-year-olds and made weekly home visits.

Children participated in their own education by planning,

doing, and reviewing their own activities.

Page 99: Dr David Williams on Health Disparities

Results at Age 40 Those who received the program had better academic

performance (more likely to graduate from high school)

Program recipients did better economically (higher

employment, annual income, savings & home ownership)

The group who received high-quality early education had

fewer arrests for violent, property and drug crimes

The program was cost effective: A return to society of $17

for every dollar invested in early education_____________________________________________________________________Schweinhart & Montie, 2005

Religion & Health: Potential Mechanisms

1. Religious institutions can provide support, intimacy, a sense of connectedness and belonging

2. Religious beliefs and values can provide systems of meaning to interpret and re-interpret stress

3. Religious beliefs can provide feelings of strength to cope with adversity

4. By encouraging moderation in all things and reducing risk taking behavior, religious involvement can reduce exposure to stress.

5. Religious participation can discourage negative health behaviors (tobacco, alcohol, drugs, risky sexual practices)

6. Religious institutions can generate stress: time demands, role conflicts, social conflicts, criticism

Page 102: Dr David Williams on Health Disparities

Religion and Adolescent Risk Behavior• Religious high school seniors are less likely than their

non-religious peers to– Carry a weapon (gun, knife, club) to school– Get into fights or hurt someone– Drive after drinking– Ride with driver who had been drinking– Smoke cigarettes– Engage in binge drinking (5 or more drinks in a

row)– Use marijuana

• Religious seniors were more likely to– Wear seat belts– Eat breakfast, green vegetables and fruit– Get regular exercise– Sleep at least 7 hours per night

Conclusions -I

1. Health officials and organizations cannot improve health by themselves

2. Improving health and reducing inequalities in health is not just about more health programs, it is about a new path to health

3. All policy that affects health is health policy

4. Health officials need to work collaboratively with other sectors of society to initiate and support social policies that promote health and reduce inequalities and health

Page 119: Dr David Williams on Health Disparities

Conclusions -II

1. Inequalities in health are created by larger inequalities in society.

2. SES and racial/ethnic disparities in health reflect the successful implementation of social policies.

3. Eliminating them requires political will for and a commitment to new strategies to improve living and working conditions.

4. Our great need is to begin in a systematic and comprehensive manner, to use all of the current knowledge that we have.

5. Now is the time
