Although much research documents the growth of a “professional middle class” among African Americans over the past several decades, we know comparatively little about how Blacks see themselves in social class terms, and whether this has changed over time. In the current study, we use data from the 1974 to 2010 General Social Surveys to analyze trends in, and the determinants of, Blacks’ social ...

Blacks have different dominant polymorphisms in the vitamin D-binding protein (DBP) gene that result in higher bioavailable vitamin D than whites. This study tested whether the lack of association between 25-hydroxyvitamin D (25OHD) and multiple sclerosis (MS) risk in blacks and Hispanics is due to differences in these common polymorphisms (rs7041, rs4588). We recruited incident MS cases and co...

The purpose of the present study was to determine sympathetic vascular transduction in young normotensive black and white adults. We hypothesized that blacks would demonstrate augmented transduction of muscle sympathetic nerve activity (MSNA) into vascular resistance. To test this hypothesis, MSNA, forearm blood flow, heart rate, and arterial blood pressure were measured during lower body negat...

This study examined racial or ethnic differences in cognitive function, cross-sectionally and longitudinally, using survey data from the Asset and Health Dynamics Among the Oldest Old. A version of the Telephone Interview for Cognitive Status (TICS), proxy assessments of cognition, and difficulties in performing daily tasks were assessed. Blacks performed below Whites on the TICS at baseline an...

1. Plasma noradrenaline concentration and plasma renin activity were measured in a control, British, urban population (n = 115) in which blacks were matched for age and sex with whites. 2. Similar measurements were made in subjects with essential hypertension (77 white and 23 black), and 48 healthy normotensive white civil servants. 3. In controls blood pressure was significantly higher in blac...

W e thank Drs. Kilpatrick and Bloomgarden (1) for their interest in our study. While we agree that the higher mean HbA1c in blacks compared with whites is well established, the collective evidence suggests that risk associations are similar. The goal of our recent study (2) was to compare the prognostic value of HbA1c to fasting glucose for risk of major complications in black and white adults....

Most studies show that blacks have higher blood pressures than whites, and that hypertension-related mortality is significantly greater. Significant pathophysiological differences are present, on the average, between blacks and whites. Blacks tend to have higher blood volume, lower plasma renin activity, and lower kallikrein excretion. While there may be black-white differences of genetic origi...

This study addresses an unexplained finding in the alcoholism treatment field: despite the health and socioeconomic disparities that exist between blacks and whites at intake, blacks and whites achieve equivalent treatment outcomes. Using Project MATCH data, this study explores religiousness and spirituality as strengths in the African American community that may account in part for equivalent ...
