Racial and Ethnic Differences in Breast Cancer Risk Factors.
Abstract
Data collection has begun for a population-based case-control study of breast cancer conducted in the San Francisco Bay Area. Cases include African-American and white women aged 35-79 years and diagnosed with breast cancer between 1 995 and 1 998. Controls are identified through random-digit dialing. Information on physical activity, sunlight exposure, dietary intake of vitamin D and phytoestrogens, and other risk factors, is collected by in-person interview. The home visit also includes measurements of anthropometry and skin pigmentation using a Chromameter. To date, 200 interviews have been completed. Data from this study will be pooled with the data collected in two on-going case-control studies that use the same methodology and questionnaire. The combined data for an estimated 1 600 cases and 1 600 controls will allow us to examine the risk factor profile among white (high risk), African-American (moderate risk), and Latina (low risk) women. We will compare the prevalence of risk factors among controls, and the magnitude of relative risks associated with the risk factors being assessed. Performing attributable risk calculations, we will estimate to what extent differences in the relative risk and/or prevalence of risk factors account for the pronounced differences in breast cancer incidence rates in these populations.
