ABSTRACT
Objective To investigate the relationship between perinatal outcome and weight gain of pregnant women with gestational diabetes mellitus (GDM).Methods Ninety-two cases pregnant women with GDM were collected.The rate of weight increasing was recorded throughout the pregnancy and body mass index (BMI) was calculated.Based on the amplitude of packets of body weight increasing,24 cases was selected during pregnancy as insufficient weight gain group,suitable weight gain group of 42 cases,and excessive weight gain group of 26 cases.Their perinatal outcome were compared.Results In excessive weight gain group,the proportion of the gestational hypertension (19.23％) and postpartum hemorrhage (23.07％) were significantly higher than suitable weight gain group and insufficient weight gain group(7.14％,8.33％ and 4.76％,4.17％),the differences were statistically significant (x2 =8.132,10.453,P ＜ 0.001).Among the three groups,no significant difference was found in terms of the incidence of anemia (3.85％,4.76％,4.17％),preterm labor (7.69％,7.14％,8.33％),premature rupture of membranes (11.54％,11.90％,12.50％) in pregnancy (P2 =0.572,0.492,0.212,P=0.63 1,0.692,0.783).The huge birth weight children rate in excessive weight gain group(15.38％) was significantly higher than suitable weight gain group and insufficient weight gain group (4.76％ and 4.17％).Among three groups,no significant difference was found in terms of the fetal distress (15.38％,16.67％,12.50％) and proportion of low birth weight children (3.85％,4.76％,4.17％) (P2 =1.034,0.572,P =0.310,0.631).Conclusion Excessive weight gain during pregnancy in GDM patients will significantly increase the gestational hypertension,the incidence of huge children and postpartum hemorrhage.Therefore,patients should be closely monitored during pregnancy weight and timely taken intervention.
