¹All values are prevalence ratios; 95% CIs in parentheses. Conducted by using Poisson regression analyses. P values refer to Wald's test. Adjusted analyses were adjusted for family income at birth, maternal schooling at birth, maternal skin color, birth order, maternal age, maternal prepregnancy weight, maternal height, smoking during pregnancy, type of payment for delivery (National Health System, private practice, private health insurance), birth weight, family income (at 4, 11, 15, or 23 y of age), schooling (at 11, 15, or 23 y of age), physical activity (at 11, 15, or 23 y of age), and smoking and alcohol consumption (at 15 or 23 y of age).
