Ethnicity, Soybean Consumption, and Mammographic Densities
Abstract
In a cross sectional design, healthy women from different ethnic backgrounds, recruited at mammography screening clinics in Hawaii, completed self-administered questions related to medical, reproductive, and diet history. After scanning the cranio-caudal mammogram films into a PC, computerized mammographic density assessment was performed. Student's t-tests, analysis of variance, and multiple linear regression were applied. The mean area of the breast was 50% larger for women with Caucasian and Native Hawaiian ancestry than for women with Chinese and Japanese ancestry. The mean dense area was 15% smaller in Chinese and Japanese women than in the Caucasian/Hawaiian group. In comparison to Caucasian/Hawaiian women, the percent densities were 20% higher in Chinese and Japanese women. Body mass index, age, menopausal status, age at menarche, parity, and hormone replacement therapy were associated with mammographic density patterns.
