Correlation of maternal weight gain during pregnancy with the outcome of pregnancy and neonatal birth weight

Objective To explore the correlation of maternal weight gain during pregnancy with the outcome of pregnancy and neonatal birth weight. Methods A total of 346 patients of single fetal primipara in my hospital from January 2011 to December 2011 were enrolled in the study. The general characteristics, maternal pre-pregnancy body mass index (BMI), the value of weight gain during pregnancy, pregnancy outcome, and birth weight were retrospective analyzed. The correlation between maternal weight gain during pregnancy and neonatal birth weight was analyzed. Results The incidences of hypertension and diabetes in the obesity group were significantly increased. In the pregnant women with weight gain of 15.1~20 kg, the incidence of pregnancy-induced hypertension, gestational diabetes were significantly increased (P0.05). The neonatal weight ratio showed no significant difference between the normal weight group and the obesity group (P0.05). Conclusion Excessive weight gain of women before pregnancy has a great influence on the outcome of pregnancy, resulting in a potential risk, but weight gain has little influence on neonatal birth weight
