Using data from the 2006 Medical Expenditure Panel Survey and the 2000 Census, we explored whether race/ethnic disparities in healthcare use were associated with residential segregation. We used five measures of healthcare use: office based physician visits, outpatient department physician visits, visits to nurses and physician’s assistants, visits to other health professionals, and having a usual source of care (USC). For each individual, we controlled for age, gender, marital status, insurance status, income, educational attainment, employment status, region, and health status. We used the racial-ethnic composition of the zip code to control for residential segregation. Our findings suggest that disparities in healthcare utilization are related to both individuals’ racial and ethnic identity and the racial and ethnic composition of their communities. Therefore, efforts to improve access to health care services and to eliminate healthcare disparities for African Americans and Hispanics should not only focus on individual-level factors but also include community-level factors.

Objective To examine the association between residential segregation and geographic access to primary care physicians (PCP) in MSAs. Data Sources We combined zip code level data on primary care physicians from the 2006 American Medical Association master file with demographic, socioeconomic and segregation measures from the 2000 US Census. Our sample consisted of 15,465 zip codes located completely or partially in an MSA. Methods We defined PCP shortage areas as those zip codes with no PCP or a population to PCP ratio of greater than 3500. Using logistic regressions, we estimated the association between a zip code’s odds of being a PCP shortage area and its minority composition and degree of segregation in its MSA. Principal Findings We found that odds of being a PCP shortage area were 67% higher for majority African American zip codes but 27% lower for majority Hispanic zip codes. The association varied with the degree of segregation. As the degree of segregation increased, the odds of being a PCP shortage area increased for majority African American zip codes, however the converse was true for majority Hispanic and Asian zip codes. Conclusions Efforts to address PCP shortages should target African American communities especially in segregated MSAs.

Multiple factors influence county-level mortality. Although county demographic and socioeconomic characteristics are important, there are independent, although weaker, associations of other environmental characteristics. Future studies should investigate these factors to better understand community mortality risk.

Background Place of residence, particularly residential segregation, has been implicated in health and health care disparities. However, prior studies have not focused on care for diabetes, a prevalent condition for minority populations. Objective To examine the association of residential segregation with a range of access and quality of care outcomes among Black and Hispanic diabetics using a nationally representative U.S. sample. Research Design Cross-sectional study using data for 1598 adult diabetics from the 2006 Medical Expenditure Panel Survey (MEPS) linked to residential segregation information for Blacks and Hispanics based on the 2000 census. Relationships of five dimensions of residential segregation (dissimilarity, isolation, clustering, concentration and centralization) with access and quality of care outcomes were examined using linear, logistic and multinomial logistic regression models, controlling for respondent characteristics and community utilization and hospital capacity. Results Black and Hispanic diabetics had comparable or better access to providers, but received fewer recommended services. Living in a segregated community was associated with more recommended services received, but also problems with seeing a specialist. The relationship of residential segregation to diabetes care varied depending on type of segregation and race/ethnic group assessed. Conclusions Residential segregation influences the care experience of diabetics in the U.S. Our study highlights the importance of investigating how different types of segregation may affect diabetes care received by patients from different race and ethnic groups.

This study’s purpose is to determine if neighborhood disadvantage, air quality, economic distress, and violent crime are associated with mortality among term life insurance policyholders, after adjusting for individual demographics, health, and socioeconomic characteristics. We used a sample of approximately 38,000 term life policyholders, from a large national life insurance company, who purchased a policy from 2002 to 2010. We linked this data to area-level data on neighborhood disadvantage, economic distress, violent crime, and air pollution. The hazard of dying for policyholders increased by 9.8% (CI: 6.0–13.7%) as neighborhood disadvantage increased by one standard deviation. Area-level poverty and mortgage delinquency were important predictors of mortality, even after controlling for individual personal income and occupational status. County level pollution and violent crime rates were positively, but not statistically significantly, associated with the hazard of dying. Our study provides evidence that neighborhood disadvantage and economic stress impact individual mortality independently from individual socioeconomic characteristics. Future studies should investigate pathways by which these area-level factors influence mortality. Public policies that reduce poverty rates and address economic distress can benefit everyone’s health.

Few studies have examined the relationship between education and diabetes among men in the United States and whether this relationship differs by race/ethnicity. This study examined whether racial disparities in diabetes existed by educational attainment in 336,746 non-Hispanic White, non-Hispanic Black, and Hispanic men 18 years of age and older in the United States. Logistic regression models were specified to examine the odds of reporting diabetes by educational attainment. Within race/ethnicity, both White and Hispanic men who had less than a high school education (odds ratio [OR] = 1.42, 95% confidence interval [CI] = [1.19, 1.69], and OR = 1.64, 95% CI = [1.22, 2.21], respectively) had consistently higher odds of diabetes than men with a bachelor’s degree or higher level of educational attainment. Educational attainment did not appear to be associated with reporting a diagnosis of diabetes in non-Hispanic Black men. Identifying why educational attainment is associated with diabetes outcomes in some racial/ethnic groups but not others is essential for diabetes treatment and management.

Racial disparities in hypertension remain a persistent public health concern in the US. While several studies report Black–White differences in the health impacts of gentrification, little is known concerning the impact of living in a gentrifying neighborhood on hypertension disparities. Data from the American Community Survey were used to identify gentrifying neighborhoods across the US from 2006 to 2017. Health and demographic data were obtained for non-Hispanic Black and White respondents of the 2014 Medical Expenditure Panel Survey (MEPS) residing in gentrifying neighborhoods. Modified Poisson models were used to determine whether there is a difference in the prevalence of hypertension of individuals by their race/ethnicity for those that live in gentrifying neighborhoods across the US. When compared to Whites living within gentrifying neighborhoods, Blacks living within gentrifying neighborhoods had a similar prevalence of hypertension. The non-existence of Black–White hypertension disparities within US gentrifying neighborhoods underscores the impact of neighborhood environment on race differences in hypertension.
