ā trends calculated by binary logistic regression. Model 1 has adjusted for age and energy intake. Model 2 is model 1+SES and number of offspring. Model 3 is models 1 and 2+dietary fiber intake. Model 4 is models 1, 2, and 3+carbohydrate and protein intake. Model 5 is the further adjustment for BMI, supplementation, physical activity, and fat intake. TRAP: total radical-trapping antioxidant parameter; FRAP: ferric reducing ability of plasma; TEAC: Trolox equivalent antioxidant capacity.
