N2 - To identify the determinants of pp-dichlorodiphenyldichloroethane (pp-DDE) in adipose tissue in subjects who participated in a cross-sectional study, we analyzed fatty acids, antioxidants, and pp-DDE in aspirates of adipose tissue of 328 postmenopausal women from 5 European countries. The overall mean of p,p'-DDE concentration was 1.66 mu g/g of fatty acids (95% confidence interval = 1.46, 1.88). In a multiple-regression analysis, the main predictors of log(10)(pp-DDE) were center of recruitment (p <.0001), adipose arachidic acid (p =.001), and adipose retinol (p =.04). These factors explained 14.9% of the overall variability of log(10)(pp-DDE), In our subjects, adipose tissue pp-DDE concentrations were only weakly related with biomarkers reflecting intake of fish and other foods. This result is consistent with the notion that p,p'-DDE exists in different foods and, given the widespread contamination of the food chain, is relatively evenly distributed among foods.
