P value was obtained by cox regression analysis, adjusted for age, having job with income, pre-pregnancy body mass index, history of cardiovascular disease, hypertension, hypothyroidism, hyperthyroidism, pregnancy hypertension, order of pregnancy, nausea during current pregnancy, multivitamin use during current pregnancy, physical activities, weight gain during current pregnancy and total energy intake.
