Longitudinal change of serum TG level of pregnant women from gestation to 42 days postpartum
There was a tendency that serum TG level increased with gestational weeks. Particularly, TG level rise by 3-fold from the first to third trimester, and decreased until 42 days postpartum (Fig. 1 A ). The cutoff point of postpartum hypertriglyceridemia defined by the P75 of non-fasting TG level at 42 days postpartum was 2.66 mmol/L.
Compared with low weight and normal weight group, TG levels of overweight and obese group were consistently higher throughout gestation and postpartum (Fig. 1 B ). Besides, at the 24th gestational week and 42 days postpartum, mean TG levels of pregnant women with normal pre-BMI were higher than those of low weight. TG levels of pregnant women with GDM were significantly higher than normal pregnant women at each gestational week and 42 days postpartum (Fig. 1 C ).
