摘要
The purpose of this study was to investigate effect of in-crease in body mass index(BMI )category on obstetric outcomes.A cohort study was conducted from 1999to2002.Women with singleton pregnancies were placed in standard BMI categories.Increase i n BMI was calculated as difference between initial BMI an d delivery BMI.ANOVA was used to compare continuous variables,and chi -square test for categorical variables.This study in-cluded 5131women:49.8%had no change in BMI cate-gory,43.9%increased by 1BMI category,and 6.3%by>1category.Increase in BMI category was associated with higher rates of gestational diabete s(P =.005),failed in-duction(P<.001),lacerations(P<.001),cesarean de-liveries(P<.001),and postpartum infection(P =.007)in normal weight women.Overweightw omen also had in-creased rates of preeclampsia(P =.002)and operative vaginal deliveries(P<.001).Obese women had higher rates of chorioamnionitis(P =.003),failed induction(P<.001),and cesarean deliveries(P =.016).In-crease in BMI category is associated with increased risk of complications.
