^*CI, confidence interval; HDL, high density lipoprotein; LDL, low density lipoprotein.

^†Minimally adjusted models included study center, time, baseline characteristics (body weight, height, waist circumference, education, smoking status, dieting to lose weight, oral contraceptive use, dietary carbohydrates and saturated fat, alcohol intake, and physical activity score), and time-dependent age and number of short pregnancies.

^‡Fully adjusted models additionally included time-dependent covariates (smoking status, months of oral contraceptive use, education, and changes in body weight, waist circumference, physical activity score, and alcohol intake).
