Ethnicity, Soybean Consumption, and Mammographic Densities
Abstract
The purpose of this study is to determine whether mammographic density patterns differ by ethnic background and to explore the possible association of a soy rich diet with mammographic density patterns. So far, 693 women have been recruited at mammography clinics in Honolulu and 465 women have completed all questionnaires. Mammographic density assessment and an exploratory analysis has been performed for 458 women for whom mammograms were available. Preliminary results on mammographic density suggest that the area of dense tissue in the breast may be smaller in Asian than in Caucasian women. However, because of their relatively smaller breast size, the percent of the breast occupied by dense tissue in Asian women may be equal to or higher than in Caucasian women. The strongest determinants of mammographic density patterns appear to be body mass index, age, and estrogen replacement therapy. We have identified associations of several reproductive and dietary factors with mammographic densities. Whereas the relation between tofu and mammographic densities was inverse before menopause, the relation was direct after menopause. Quality control of mammographic density assessments and more detailed statistical analyses are necessary to complete this project.
