Many studies have suggested that African Americans have a higher prevalence of hypertension than whites. The authors conducted a prospective study of hypertension incidence from 1987-1988 to 1994-1995 in 140 African American and 237 white adults aged 30 to 54 years at baseline. The study participants were screened for participation in the Trials of Hypertension Prevention, phase 1, an 18-month ...

OBJECTIVE To identify unique cultural variables for African Americans that might limit the effectiveness of behavioral interventions in clinical trials. DESIGN Focus group discussions lasting 90 minutes. SETTING Outpatient, clinical research center. PATIENTS Twenty-six African-American men and women, who completed the screening process but were ineligible for the PREMIER study, participat...

BACKGROUND Colorectal cancer (CRC) is a common form of malignancy and a leading cause of death in the United States. Screening decreases CRC incidence and mortality. African Americans are at an increased risk of developing CRC, and recommendations are to initiate screening at the age of 45. This study aims to assess the rate of screening for colorectal cancer in African Americans between the ag...

4. Community-based outreach is a strategy based on the assumption that a. older African Americans are disinterested in their own health care. b. older African Americans are reluctant to leave their communities. c. it is impossible to fully understand an individual without knowing his or her community. d. it is impossible to effectively deliver audiology and speechlanguage pathology services to ...

African-Americans have been under-represented in genetic studies of rheumatoid arthritis (RA) susceptibility and severity. Genetic and non-genetic factors influencing the radiographic severity of RA and its response to treatment are poorly understood, particularly in African-Americans. The Consortium for the Longitudinal Evaluation of African-Americans with early RA (CLEAR) Registry, a collabor...

OBJECTIVE African Americans often report greater pain than do Caucasians, but the factors responsible for this discrepancy are not known. We examined whether alexithymia-the trait of difficulty identifying and describing one's feelings and lacking introspection-may contribute to this ethnic group difference. We tested whether the mean level of alexithymia is higher, and whether alexithymia and ...

BACKGROUND Regular aspirin use, particularly as secondary prevention, reduces morbidity from heart disease and stroke. Few studies have examined racial/ethnic differences in aspirin use for the prevention of cardiovascular disease (CVD). METHODS Data from the 2001 Behavioral Risk Factor Surveillance System (n=2,514 African Americans; n=865 Hispanics; n=28,038 Whites) were used to assess racia...

Quantifying patterns of population structure in Africans and African Americans illuminates the history of human populations and is critical for undertaking medical genomic studies on a global scale. To obtain a fine-scale genome-wide perspective of ancestry, we analyze Affymetrix GeneChip 500K genotype data from African Americans (n = 365) and individuals with ancestry from West Africa (n = 203...

This study examined whether African American children's perceptions of occupational status and their own vocational interests are affected by racial segregation of the workforce. Children (N = 92) rated familiar occupations with respect to status, desirability, and stereotyping. Children also rated novel jobs that had been depicted with African Americans, European Americans, or both African and...

This study was conducted to compare lipid components of sebum from persons from three ethnic backgrounds-Caucasian, African American and Northern Asian. Men and women with no acne in two age groups (18‒25 y and 35‒45 y) were recruited. Skin surface hydration (SkiCon 200EX and NovaMeter), barrier function (Delfin VapoMeter), high-resolution clinical imaging, self-assessments and two pairs of seb...
