Main findings
In this prospective study of pregnant women, we specified the increasing
trend of gestational TG and its decline after delivery. There was a
tendency that overweight and obese women and women with GDM had higher
serum TG throughout gestation and postpartum than normal women. Serum TG
during pregnancy were positively associated with TG at 42 days
postpartum. High gestational TG level increased the risk of postpartum
hypertriglyceridemia, especially in early pregnancy. TG trend of change
during pregnancy was positively associated with postpartum TG and risk
of postpartum hypertriglyceridemia. TG level should be controlled under
a threshold as 1.12, 1.93, 2.35 and 3.08 mmol/L at
6-8th, 16th, 24thand 36th gestational week, respectively. The
association between gestational TG and increased risk of postpartum
hypertriglyceridemia was more significant among pregnant women with
normal pre-BMI and without GDM.
