Abstract:
Objective To evaluate the relations between hypertensive disorders (HDP) in pregnancy and early-term birth.Methods A total of 3 474 pregnant women were consecutively recruited.Demographic information was collected in early pregnancy.HDP was diagnosed in the first,second and third trimesters,respectively.On the basis of precise evaluation on gestation age,early-term birth was defined as gestational age of 37-38 weeks + 6 days.Logistic regression models were conducted to examine the associations between HDP and early-term birth.Results The current study included 3 260 pregnant women,with the rates of HDP,pregnancy-induced hypertension syndrome and pre-eclampsia as 6.0％ (n=194),4.2％ (n=137) and 1.8％ (n=57),respectively.After controlling for potential confounders,no significant differences between pregnancy-induced hypertension syndrome and early-term birth (OR=1.49,95％C1:0.94-2.36) were found.Pre-eclampsia appeared to have increased the risk of early-term birth (OR=4.46,95％ CI:2.09-9.54).Conclusion Pre-eclampsia could significantly increase the risk of early-term birth.This finding suggested that early detection and intervention programs were helpful in reducing the risk of early-term birth.
