Description:Purpose
Research on the role of red meat and poultry consumption in breast carcinogenesis is inconclusive, but the evidence in African American (AA) women is lacking. The association between consuming meat and breast cancer risk was examined in the Women’s Circle of Health Study involving 803 AA cases, 889 AA controls, 755 Caucasian cases, and 701 Caucasian controls.
Methods
Dietary information was collected using a Food Frequency Questionnaire. Odds ratios (OR) and 95% confidence intervals (CI) were obtained from logistic regression models adjusting for potential covariates.
Results
Comparing the fourth vs. the first quartile, among Caucasian women, processed meat (OR=1.48; 95% CI: 1.07–2.04), unprocessed red meat (OR=1.40; 95% CI: 1.01–1.94) and poultry intakes (OR=1.42; 95% CI: 1.01–1.99) increased breast cancer risk. Risk associated with poultry intake was more dominant in premenopausal women (OR=2.33; 95% CI: 1.44–3.77) and for women with ER- tumors (OR=2.55; 95% CI: 1.29–5.03) in the Caucasian group. Associations in AA women were mostly null except for a significant increased risk trend with processed meat consumption for ER+ tumors (OR=1.36; 95% CI: 0.94–1.97, p trend=0.04).
Conclusions
Overall, associations between breast cancer risk and consumption of red meat and poultry were of different magnitude in AA and Caucasian women, with further differences noted by menopausal and hormone receptor status in Caucasian women. This is the first study to examine racial differences in meat and breast cancer risk, and represents some of the first evidence in AA women.
