BACKGROUND Gastric cancer incidence in African Americans is twice that of whites, and differing prevalence of Helicobacter pylori strain-specific isolates may help explain the disparity. METHODS Serum levels of antibodies to each of 15 H. pylori proteins were assessed using multiplex serology for a sample of 689 African American and white participants from the Southern Community Cohort Study....

We examined differences in positive aspects of caregiving (PAC) among 275 African American and 343 Caucasian caregivers of individuals with Alzheimer's disease from the National Institutes of Health Resources for Enhancing Alzheimer's Care Health (REACH) study sites in Birmingham, Memphis, and Philadelphia. African Americans reported higher scores on PAC than did Caucasians. African Americans' ...

Recent theoretical and empirical studies of the social determinants of health inequities have shown that economic deprivation, multiple levels of racism, and neighborhood context limit African American health chances and that African Americans' poor health status is predicated on unequal opportunity to achieve the American Dream. President Obama's election has been touted as a demonstration of ...

Based on questionnaire responses from 412 undergraduate students, this study sought to examine specific perceptions (i.e., occupational roles, negative personality characteristics, low achieving status, and positive stereotypes) of African American portrayals on television. Results revealed that television viewers perceive the occupational roles and personality characteristics that African Amer...

The impact of participation in Head Start is investigated using a national sample of children. Comparisons are drawn between siblings to control for selection. Head Start is associated with large and significant gains in test scores among both whites and African-Americans. However, among African-Americans, these gains are quickly lost. Head Start significantly reduces the probability that a whi...

OBJECTIVE Nearly half of African-Americans are classified as obese. Perceived racism has been associated with obesity, yet the internal experiences of racism have received little attention. African Americans who face racism may "ready themselves" to cope through survival strategies, including race-related vigilance. This study explores the association between race-related vigilance and obesity ...

African Americans have high incidence rates of end-stage renal disease (ESRD) labeled as due to hypertension. As recent studies showed strong association with idiopathic and HIV-related focal segmental glomerulosclerosis and non-muscle myosin heavy chain 9 (MYH9) gene polymorphisms in this ethnic group, we tested for MYH9 associations in a variety of kidney diseases. Fifteen MYH9 single-nucleot...

Knowledge of the impact of racism on the psyches of African-Americans is limited by the following considerations: the tendency among European-Americans to deny, minimize, and rationalize the existence of racism; the tendency among European-Americans to ascribe inferior status to African-Americans; the application of many stereotypes and myths to African-Americans that serve to have them viewed ...

The World Health Organization estimates that the number of obese and overweight adults has increased to 1.6 billion, with concomitant increases in comorbidity. While genetic factors for obesity have been extensively studied in Caucasians, fewer studies have investigated genetic determinants of body mass index (BMI; weight (kg)/height (m)(2)) in African Americans. A total of 38 genes and 1,086 s...
