Ethnicity-related variation in XXXX risk factors.

@entity1 @entity167 @entity0 @entity28
BACKGROUND: A variety of factors are predictors of @entity0 risk. However, the studies conducted to establish these risk factors have rarely included African American @entity1 . The few studies with sufficient numbers of African-American @entity1 suggest that risk factors for @entity0 among African-American @entity1 are similar to those of white @entity1 . Although risk factors may be similar for African-American and white @entity1 , differences in the prevalence of risk factors may explain the differences in patterns of incidence. METHODS: The authors reviewed the epidemiologic studies of @entity0 among African-American @entity1 and identified resources with information regarding the prevalence of risk factors among African American and white @entity1 . RESULTS: Considerable variation exists in the studies of @entity0 risk factors among African American @entity1 . Because few studies have included sufficient numbers of African-American @entity1 , no firm conclusions can be drawn regarding whether risk estimates for African American @entity1 differ from those of white @entity1 . Estimates of the prevalence of @entity0 risk factors indicate that African American and white @entity1 differ in terms of their ages at menarche, menstrual cycle patterns, birth rates, lactation histories, patterns of oral contraceptive use, levels of @entity28 , frequency of menopausal hormone use, physical activity patterns, and @entity167 intake. CONCLUSIONS: The risk factor profile of African-American @entity1 appears to differ from that of white @entity1 . This may explain in part, the higher incidence rates for African Americans before age 45 years and the lower incidence rates at older ages. Discussions of these data at a workshop highlighted the need for future research on @entity0 risk among African Americans. This research should acknowledge the heterogeneous heritage, cultural beliefs, and cultural knowledge of African-American @entity1 . Studies conducted in collaboration with the African-American community of @entity1 and with the @entity0 advocacy community can benefit from assistance in the design of questionnaires and recruitment of @entity1 .
