Health Inequalities: Trends, Progress, and Policy

Health inequalities, which have been well documented for decades, have more recently become policy targets in developed countries. This review describes time trends in health inequalities (by sex, race/ethnicity, and socioeconomic status), commitments to reduce health inequalities, and progress made to eliminate health inequalities in the United States, United Kingdom, and other OECD countries. Time-trend data in the United States indicate a narrowing of the gap between the best- and worst-off groups in some health indicators, such as life expectancy, but a widening of the gap in others, such as diabetes prevalence. Similarly, time-trend data in the United Kingdom indicate a narrowing of the gap between the best- and worst-off groups in some indicators, such as hypertension prevalence, whereas the gap between social classes has increased for life expectancy. More research and better methods are needed to measure precisely the relationships between stated policy goals and observed trends in health inequalities.

Race/Ethnicity and Hypertension: The Role of Social Support

BACKGROUND Social support is an important determinant of health, yet understanding of its contribution to racial disparities in hypertension is limited. Many studies have focused on the relationship between hypertension and social support, or race/ethnicity and social support, but few have examined the inter-relationship between race/ethnicity, social support, and hypertension. The objective of this study was to determine whether the relationship between race/ethnicity and hypertension varied by level of social support. METHODS Data from the National Health and Nutrition Examination Survey (NHANES) 2001-2006 were used to calculate the odds ratios (ORs) for the association between hypertension and race/ethnicity by levels of social support. Hypertension was defined as systolic blood pressure (BP) >or=140 mm Hg and/or diastolic BP >or=90 mm Hg or having been prescribed antihypertensive medication. Social support was defined by emotional and financial support, and marital status. RESULTS Black/white ORs of hypertension increased as social support decreased; that is, the race difference among those without social support was larger compared to those with social support. Contrarily, Mexican American/white ethnic differences were only observed among those with social support; Mexican Americans with social support had lower odds of hypertension than their white counterparts. CONCLUSIONS This study observed that the relationship between race (but not ethnicity) and hypertension varies by social support level. Results suggest there may be beneficial effects of social support on hypertension among blacks, however, the possible impact of social support on ethnic differences in hypertension remains unclear.

The Effect of Religious Service Attendance on Race Differences in Depression: Findings from the EHDIC-SWB Study

In the EHDIC-SWB study, African-Americans are less likely to have depression than non-Hispanic whites. Religious service attendance is one possible explanation because studies have shown an inverse relationship between religious service attendance and depression. We examined the relationship between race, religious service attendance, and depression in 835 African-American and 573 non-Hispanic white adults aged 18 and older in the Exploring Health Disparities in Integrated Communities-Southwest Baltimore (EHDIC-SWB) study. Religious service attendance was measured according to participants’ response to “how often do you attend religious services?” Depression was measured using the Patient Health Questionnaire. African-Americans attended religious services more frequently than non-Hispanic whites, and had a lower percentage of depression (10.1% vs. 15.4%; p-value <0.05). After adjusting for the demographic variables and health-related characteristics, African-Americans displayed lower odds of having depression (OR = 0.68, 95% CI: 0.47–0.97) compared to non-Hispanic whites. However, when including religious service attendance in the model, we found race differences in depression (OR = 0.76, 95% CI: 0.52–1.11) were no longer significant. We concluded that among individuals living in a low-income, integrated urban environment, race disparities in depression were eliminated after accounting for race differences in religious service attendance. This suggests religious service attendance may serve as a protective factor against depression for African-Americans.

Race, social and environmental conditions, and health behaviors in men

Although understanding race differences in health behaviors among men is an important step in reducing disparities in leading causes of death in the United States, progress has been stifled when using national data because of the confounding of race, socioeconomic status, and residential segregation. The purpose of this study is to examine the nature of disparities in health behaviors among African American and white men in the Exploring Health Disparities in Integrated Communities Study-Southwest Baltimore, which was conducted in a racially integrated neighborhood of Baltimore to data from the 2003 National Health Interview Survey. After adjusting for age, marital status, insurance, income, educational attainment, poor or fair health, and obesity status, African American men in National Health Interview Survey had greater odds of being physically inactive (odds ratio [OR] = 1.48; 95% confidence interval [CI], 129-1.69), reduced odds of being a current smoker (OR = 0.77; 95% CI, 0.65-0.90), and reduced odds of being a current drinker (OR = 0.58; 95% CI, 0.50-0.67). In the Exploring Health Disparities in Integrated Communities Study-Southwest Baltimore sample, African American and white men had similar odds of being physically inactive (OR = 0.79; 95% CI, 0.50-1.24), being a current smoker (OR = 0.86; 95% CI, 0.60-1.23), or being a current drinker (OR = 1.34; 95% CI, 0.81-2.21). Because race disparities in these health behaviors were ameliorated in the sample where African American and white men were living under similar social, environmental, and socioeconomic status conditions, these findings suggest that social environment may be an important determinant of health behaviors among African American and white men. Public health interventions and health promotion strategies should consider the social environment when seeking to better understand mens health disparities.

Disparities in alcohol use: Does race matter as much as place?

OBJECTIVES National estimates of race differences in alcohol use suggest that whites are more likely to be current and binge users of alcohol. These findings fail to account for race differences in the social and environmental context where people live. This study aims to determine whether race disparities persist in alcohol use among individuals who share similar social and environmental conditions. METHODS We compared race disparities between individuals living in a low-income racially integrated urban community without race differences in socioeconomic status (EHDIC-SWB) to individuals from the National Health Interview Survey (NHIS 2003) to determine if race disparities in alcohol use were attenuated in the integrated environment. RESULTS In the NHIS 2003 sample, compared to whites, African Americans had lower odds of being a current drinker (OR=0.56, 95% CI=0.49-0.64) and binge drinker (OR=0.68, 95% CI=0.58-0.80) independent of covariates. However in the EHDIC-SWB sample, African Americans had similar odds of being a current drinker (OR=0.94, 95% CI=0.67-1.33) and binge drinker (OR=1.02, 95% CI=0.77-1.35) compared to whites. CONCLUSIONS Among individuals who share similar social and environmental risk exposures, race group differences in alcohol use patterns are similar.

Disentangling Race and Social Context in Understanding Disparities in Chronic Conditions among Men

Disparities in men’s health research may inaccurately attribute differences in chronic conditions to race rather than the different health risk exposures in which men live. This study sought to determine whether living in the same social environment attenuates race disparities in chronic conditions among men. This study compared survey data collected in 2003 from black and white men with similar incomes living in a racially integrated neighborhood of Baltimore to data from the 2003 National Health Interview Survey. Multivariable logistic regression models estimated to determine whether race disparities in chronic conditions were attenuated among men living in the same social environment. In the national sample, black men exhibited greater odds of having hypertension (odds ratio [OR] = 1.58, 95 % confidence interval [CI] 1.34, 1.86) and diabetes (OR = 1.62, 95 % CI 1.27–2.08) than white men. In the sample of men living in the same social context, black and white respondents had similar odds of having hypertension (OR = 1.05, 95 % CI 0.70, 1.59) and diabetes (OR = 1.12, 95 % CI 0.57–2.22). There are no race disparities in chronic conditions among low-income, urban men living in the same social environment. Policies and interventions aiming to reduce disparities in chronic conditions should focus on modifying social aspects of the environment.

Addressing health inequalities in the United States: Key data trends and policy action

Health inequalities, which have been well documented for decades, have recently become policy targets in the United States. This report summarizes current patterns and trends in health inequalities, commitments to reduce health inequalities, and progress made to eliminate health inequalities. Time trend data indicate improvements in health status and major risk factors but increases in morbidity, with black and lowereducation individuals experiencing a disproportionate burden of disease. A common policy response has been priority setting in the form of national objectives or goals to address health inequalities. More research and better methods are needed to precisely measure relationships between stated policy goals and observed trends in health inequalities. Despite these challenges, the United States has made commitments to advancing research and policy to eliminate health inequalities. There remain considerable opportunities for local public health systems and practioners to develop innovative solutions to address the problem of health inequalities, particularly related to action steps, and for researchers to address knowledge gaps in the scientific literature related to the evaluation and measurement of progress aimed at addressing health inequalities.

Differences in Obesity Among Men of Diverse Racial and Ethnic Background

Racial/ethnic disparities exist in obesity prevalence among men, with Hispanic men exhibiting the highest prevalence compared with non-Hispanic White and non-Hispanic Black men. Most studies do not parse out Hispanic groups; therefore, it is unclear whether the increases in obesity rates among Hispanic men applies to all groups or if there are particular groups of Hispanic men that are driving the increase. The goal of this study is to examine the variations in obesity among men of diverse racial/ethnic backgrounds and determine if obesity is affected by nativity. The data used in this study were from 11 years (2002-2012) of the National Health Interview Survey. Logistic regression was used to examine the relationship between race/ethnicity, obesity, and nativity. After adjusting for covariates, there are differences in obesity prevalence, with the largest prevalence among Puerto Rican men and Mexican American men. Consistent with previous literature, it has been suggested that men born in the United States are more likely to be obese than men born outside the United States. This study underscores the importance of distinguishing Hispanic groups when examining obesity, and provides information for future, targeted intervention strategies related to obesity among high-risk groups.

Race disparities in cardiovascular disease risk factors within socioeconomic status strata

PURPOSE Racial differences in socioeconomic status (SES) explain some, but not all, of racial disparities in cardiovascular disease (CVD) risk. To address this, race disparities among higher SES individuals need to be assessed. The purpose of this study was to assess whether racial disparities in CVD risk factors differ by SES levels. METHODS Data from the National Health and Nutritional Examination Survey 2007-2014 were used to calculate racial differences in hypertension, high cholesterol, diabetes, and obesity. Interactions between race and SES were assessed. RESULTS African Americans had higher odds of hypertension (odds ratio [OR], 1.90; 95% confidence interval [CI], 1.72-2.09), diabetes (OR, 1.66; 95% CI, 1.33-2.07), and obesity (OR, 1.64; 95% CI, 1.46-1.83) than whites. Significant interactions between race and income greater than or equal to

The Role of Marital Status in Physical Activity Among African American and White Men

100,000 were observed for obesity (OR, 1.55; 95% CI, 1.24-1.94) and between race and education (college graduate or more; OR, 1.58; 95% CI, 1.16-2.15). Disparities in diabetes were observed in the highest SES groups, but not among those in the lowest SES groups. CONCLUSIONS Race disparities in some CVD risk factors varied by SES levels. Results suggest that race disparities in obesity are larger among those with income greater than or equal to
