Abstract：Objective To discuss the effects of pre-pregnancy body mass index (BMI) of gestational diabetes mellitus on perinatal outcomes.Methods Two hundred and thirty-eight cases of pregnant women with gestational diabetes mellitus, regularly checked-up and delivery in Navy Gene-ral Hospital during April 2012 to March 2013, were divided into four groups based on the pre-preg-nancy BMI.BMI<18.5 kg/m 2 for low body weight group, 18.5 kg/m 2≤BMI<25.0 kg/m 2 for nor-mal group, 25.0 kg/m 2≤BM<28.0 kg/m 2 for overweight group, and BMI≥28.0 kg/m 2 for obesity group, the perinatal outcomes including the preterm delivery rates, incidence of macrosomia, cesa-rean section rates, neonatal birth weight, neonatal blood glucose levels were compared between groups.The difference of accepting regular treatment rate was analyzed.Results Macrosomia rate, cesarean section and ratio to receive formal treatment were significantly different among each group. The incidence of macrosomia in the overweight group and obesity group was obviously higher than that in the normal group (P<0.05), but was almost the same with that in the low body weight group (P>0.05).The incidence of cesarean section and the ratio without formal treatment increased sig-nificantly in the overweight group than those in the low body weight and normal group (P<0.05), but was almost the same with that in the obese group(P>0.05).The weight gain and the BMI growth during the period of gestation decreased significantly in the obesity group than those in the other three groups (P<0.05).The neonatal blood glucose level was lower in the overweight group than that in the low body weight group (P<0.01).There were no significant differences between the four groups on the premature delivery rate and neonatal weight ratio(P>0.05).Conclusion The pre-pregnancy body mass index of gestational diabetes mellitus has significant correlation with the perinatal outcomes.The BMI should be controlled between 18.5- 25.0 kg/m 2 before pregnancy.We should strengthen the management on the pre-pregnancy overweight and obese groups, control the weight gain during pregnancy to reduce the adverse pregnancy outcomes.
