摘　　要：目的:探讨孕前BMI及孕期增重对妇女产后2年体重变化的影响。方法:采用历史-前瞻性队列研究设计,选择合肥市某区妇幼保健站进行产后42天体检的418例妇女为研究人群并建立观察队列,采用问卷调查和查阅孕产妇管理档案的方法收集基线资料,于产后42天及6月、12月、18月、24月对其进行连续性随访观察各时点的体重值。结果:418例产妇产后42天、6月、12月、18月、24月恢复至孕前体重率分别为7.42%、15.38%、32.58%、24.89%、27.97%。孕前BMI各组(<18.5kg/m2组,18.5kg/m2≤BMI<24kg/m2组,≥24kg/m2组)产后各时点比较,差异均有统计学意义(P<0.05)。孕期增重3组(孕期增重较少组、孕期增重适中组和孕期增重较多组)妇女产后42天、18月和24月体重变化值比较,差异均有统计学意义(P<0.05)。结论:孕前BMI、孕期增重影响产后2年体重的变化,根据孕前BMI将孕期增重控制在合理范围内可有效促进妇女产后体重恢复到孕前水平并控制远期肥胖的发生。Objective：To explore the relationship between the pre-pregnant BMI and weight gain during pregnancy with weight changes two years after delivery. Methods：418 women who attained postpartum examination 42 days after delivery in a district of Maternal and Child Health Center in Hefei were recruited in this history prospective cohort study. We ob-tained the baseline data from pregnancy care management system. Participants were followed up 42 days,6,12,18,24months postpartum. The information about weight were collected during follow-up investigations. Results：418 participants returned to pre-pregnancy weight rates were 7. 42%,15. 38%,32. 58%,24. 89%,27. 97% 42 days,6,12,18,24months postpartum,re-spectively. Pre-pregnant BMI and weight changes were significantly correlated （ P〈0. 05 ） at different time points across groups. Three groups ＇ weight changes were significantly different. Weight gains during pregnancy and weight changes were significantly correlated （ P〈0 . 05 ） 42 days,18,24 months postpartum. Conclusion：Pre-pregnacy BMI and weight gain during preg-nancy were important factors for weight changes postpartum. Controlling weight gain during pregnancy within a reasonable range can effectively promote women to return to pre-pregnancy weight levels after delivery and control the weight in the long-term according to different pre-pregnant BMI.
