摘　　要：目的探索妇女孕前体重及孕期增重对产后体重滞留的影响。方法采用历史-前瞻性队列研究设计,选择合肥市某区的产后妇女作为观察对象,于产后3个月建立观察队列,通过孕期保健档案和信息系统获取产前检查信息,于产后3、6、9和12个月连续观察。观察指标包括基线资料、孕前体重和孕期增重、产后一年内不同时间点的体重。结果产后3、6、9和12个月时BMI恢复到正常范围者所占的比例分别为61.92%、68.73%、78.18%和84.24%。孕前BMI不同的妇女孕期增重和体重滞留在3、6、9和12个月各个时间点上均存在差异,孕前BMI较高组与孕前BMI适中组、孕前BMI较低组分别进行比较,差异具有统计学意义。孕期增重和时间对产后体重的恢复均具有独立的效应,但两者之间不存在交互效应。结论孕前BMI、孕期体重增加是产后体重滞留的重要因素。根据孕前BMI指导孕期合理体重增加,能减少产后体重滞留,促进产后恢复。Objective To explore the relationship between pre-pregnancy BMI, antepartum weight gain and postpartum weight retention. Methods 793 postpartum women from certain district of Hefei city were recruited as the observational cohort at 3rd month after delivery. We obtained antepartum information from pregnancy care management system and conducted questionnaire and measurement at 3,6,9 and 12 months postpartum. The observation items included baseline data, antepartum weight, weight gain during pregnancy, weight of different timing during one year after delivery. Results The proportion of pregnant women whose BMI back to normal during 3, 6, 9 and 12 months were respectively 61.92%, 68.73%, 78.18% and 84.24%. Pre- pregnancy BMI of women＇ s weight gain and weight retention during 3, 6, 9 and 12 months differs. After comparing the differences between higher pre-pregnaney BMI group, medium pre-pregnancy BMI group and lower pre-pregnaney BMI group, the differences were statistically significant. There were independent effects between weight gain during pregnancy, time and postpartum weight recovery, but no interactions were shown between them. Conclusion Pre-pregnancy BMI and weight gain during pregnancy were important factors for postpartum weight retention. Using pre-pregnancy BMI as guidance to build reasonable weight gain during pregnancy might reduce the occurrence of postpartum weight retention and promote postpartum recovery.
