Race-Ethnicity, Poverty, Urban Stressors, and Telomere Length in a Detroit Community-based Sample

Residents of distressed urban areas suffer early aging-related disease and excess mortality. Using a community-based participatory research approach in a collaboration between social researchers and cellular biologists, we collected a unique data set of 239 black, white, or Mexican adults from a stratified, multistage probability sample of three Detroit neighborhoods. We drew venous blood and measured telomere length (TL), an indicator of stress-mediated biological aging, linking respondents’ TL to their community survey responses. We regressed TL on socioeconomic, psychosocial, neighborhood, and behavioral stressors, hypothesizing and finding an interaction between poverty and racial-ethnic group. Poor whites had shorter TL than nonpoor whites; poor and nonpoor blacks had equivalent TL; and poor Mexicans had longer TL than nonpoor Mexicans. Findings suggest unobserved heterogeneity bias is an important threat to the validity of estimates of TL differences by race-ethnicity. They point to health impacts of social identity as contingent, the products of structurally rooted biopsychosocial processes.

The Role of Socioeconomic Factors in Black–White Disparities in Preterm Birth

OBJECTIVES We investigated the role of socioeconomic factors in Black-White disparities in preterm birth (PTB). METHODS We used the population-based California Maternal and Infant Health Assessment survey and birth certificate data on 10 400 US-born Black and White California residents who gave birth during 2003 to 2010 to examine rates and relative likelihoods of PTB among Black versus White women, with adjustment for multiple socioeconomic factors and covariables. RESULTS Greater socioeconomic advantage was generally associated with lower PTB rates among White but not Black women. There were no significant Black-White disparities within the most socioeconomically disadvantaged subgroups; Black-White disparities were seen only within more advantaged subgroups. CONCLUSIONS Socioeconomic factors play an important but complex role in PTB disparities. The absence of Black-White disparities in PTB within certain socioeconomic subgroups, alongside substantial disparities within others, suggests that social factors moderate the disparity. Further research should explore social factors suggested by the literature-including life course socioeconomic experiences and racism-related stress, and the biological pathways through which they operate-as potential contributors to PTB among Black and White women with different levels of social advantage.

CAN'T BUY ME WHITENESS

A basic tenet of public health is that there is a robust relationship between socioeconomic status and health. Researchers widely accept that persons at average or median levels of socioeconomic status have better health compared to those at lower levels—with a detectable, if diminishing, gradient at even higher levels of socioeconomic status. The research on which this tenet is based, however, focuses largely on Whites, especially on White men. Yet according to the full range of extant findings, the magnitude and in some cases the direction of this relationship vary considerably for other demographic groups. I argue that the failure to clearly qualify study conclusions when they are restricted to the study of Whites impedes our understanding of the varying relationship between socioeconomic status and health for different demographic groups. Such an impediment is particularly harmful when considering health inequalities among populations defined by race and ethnicity. Frameworks and models based on traditional socioeconomic measures may mask heterogeneity, overestimate the benefits of material resources, underestimate psychosocial and physical health costs of resource acquisition for some groups, and overlook the value of alternative sociocultural orientations. These missed opportunities have grave consequences: large racial/ethnic health disparities persist while the health disadvantages of Black Americans continue to grow in key aspects. A new knowledge base is needed if racial/ethnic health disparities are to be eliminated, including new guiding theoretical frameworks, reinterpretations of existing research, and new empirical research. This article aims to initiate discussion on all three dimensions.

Race/Ethnicity, Socioeconomic Characteristics, Coethnic Social Ties, and Health: Evidence From the National Jewish Population Survey

OBJECTIVES We explored whether a White ethnic group with a history of structural disadvantage, Jewish Americans, shows evidence of continuing health impact independent of socioeconomic position (SEP), whether coethnic social ties appear health protective, and whether the strength of any protection varies by SEP. METHODS In a series of ordered logistic regressions, we analyzed data from the National Jewish Population Survey, 2000-2001, regressing self-rated health on race/ethnicity, education, and income for US Blacks, Jews, and other Whites and, for Jews alone, indicators of coethnic social ties. RESULTS controlling for SEP indicators, the self-rated health of Jews converged with that of Blacks and was significantly worse than that of other Whites. Access to coethnic social ties was associated with better self-rated health among Jews, with the strongest estimated association among those of lower SEP. CONCLUSIONS The finding that a White ethnic group with a favorable socioeconomic profile reported significantly worse health than did other Whites, after controlling for SEP, calls for better understanding of the complex interplay of cultural, psychosocial, and socioeconomic resources in shaping population health.

Sociocultural and Socioeconomic Influences on Type 2 Diabetes Risk in Overweight/Obese African-American and Latino-American Children and Adolescents

Purpose. It is unclear whether sociocultural and socioeconomic factors are directly linked to type 2 diabetes risk in overweight/obese ethnic minority children and adolescents. This study examines the relationships between sociocultural orientation, household social position, and type 2 diabetes risk in overweight/obese African-American (n = 43) and Latino-American (n = 113) children and adolescents. Methods. Sociocultural orientation was assessed using the Acculturation, Habits, and Interests Multicultural Scale for Adolescents (AHIMSA) questionnaire. Household social position was calculated using the Hollingshead Two-Factor Index of Social Position. Insulin sensitivity (SI), acute insulin response (AIRG) and disposition index (DI) were derived from a frequently sampled intravenous glucose tolerance test (FSIGT). The relationships between AHIMSA subscales (i.e., integration, assimilation, separation, and marginalization), household social position and FSIGT parameters were assessed using multiple linear regression. Results. For African-Americans, integration (integrating their familys culture with those of mainstream white-American culture) was positively associated with AIRG (β = 0.27 ± 0.09, r = 0.48, P < 0.01) and DI (β = 0.28 ± 0.09, r = 0.55, P < 0.01). For Latino-Americans, household social position was inversely associated with AIRG (β = −0.010 ± 0.004, r = −0.19, P = 0.02) and DI (β = −20.44 ± 7.50, r = −0.27, P < 0.01). Conclusions. Sociocultural orientation and household social position play distinct and opposing roles in shaping type 2 diabetes risk in African-American and Latino-American children and adolescents.
