Appropriate weight gain during pregnancy in women complicated with gestational abnormal glucose metabolism / 中华围产医学杂志

ABSTRACT

Objective To investigate the appropriate range of gestational weight gain in pregnant women with abnormal glucose metabolism.Methods A retrospective study was conducted on 661 term singleton pregnant women with gestational abnormal glucose metabolism,who delivered in the Department of Obstetrics and Gynecology of Peking University First Hospital from Jan.2005 to Dec.2007,by reviewing the medical records.All sujects were divided into 4 groups according to their body mass index (BMI) before pregnancy:group Ⅰ (n=40):BMI<18.5;group Ⅱ (n=400):BMI18.5-23.9;group Ⅲ (n=162):BMI 24.0-27.9;group Ⅳ (n=59):BMI≥28.0.The weight gain among different groups and that between women who delivered normal birth weight infant and maerosomia were analyzed.The weight gain of pregnant women who delivered babies weighing 3000～3500 g in each group was determined as the appropriate weight gain for that group.Results The same results were achieved that the weight gain in pregnant women who delivered macrosomia was significantly higher than those who delivered normal birth weight newborns in each group,ie,the weight gains for women who had macrosomia and normal birth weight infants were (17.0±5.2) kg and (14.1±4.7) kg in group Ⅱ,(16.8±7.3) kg and (11.9±5.1) kg in group Ⅲ and (18.3±6.7) kg and (11.2±5.4) kg in group Ⅳ,respectively (P<0.05).The appropriate ranges of weight gain for each group were (15.6±3.3) kg,(14.0-18.0) kg for group Ⅰ,(13.9±4.6) kg,(11.0-16.5) kg for group ]],(11.5±5.2)kg,(9.0-15.0) kgforgroup Ⅲ,(10.1±2.9) kg,(7.0-12.7) kg forgroup Ⅳ.Conclusions Appropriate weight gain based on prepregnant BMI,together with glucose monitoring in women with gestational abnormal glucose metabolism,is helpful for fetal weight control.
