| Objective To investigate the effect of pregnancy body mass index (BMI) and BMI growth during pregnancy on pregnancy complications and neonatal outcome. Methods The clinical data of 1261 cases admitted to our hospital from December 2014 to December 2014 were retrospectively analyzed, the cased were grouped as thin, normal, overweight and obese according to BMI before childbirth, and then were divided into BMI<3.8 kg/m2 group (group A), 3.8 kg/m2 ≤ BMI<7.5 kg/m2 group (group B) and BMI ≥ 7.5 kg/m2 group (group C) based on the physique growth index during pregnancy. The pregnancy complications and neonatal outcome of each group were analysed and compared. Results The incidence of pregnancy induced hypertension (PIH), gestational diabetes mellitus (GDM), cesarean section, macrosomia of overweight and obese group was higher than that of normal and thin group(P<0.05); the incidence of PIH, GDM, cesarean section, macrosomia of Group C was higher than that of group A and B(P<0.05); the incidence of premature birth, low birth weight of thin group and A group was higher than that of other groups(P<0.05); there was no statistically significant difference in the incidence of premature rupture of membranes, postpartum hemorrhage in all groups (P>0.05). Conclusion Weight is one of the most important factors affecting pregnancy complications and neonatal outcome, and attention should be paid to pregnancy weight gain and control in appropriate range. |
