目的：本随机试验旨在测试妊娠期代餐行为干预是否能提高妇女恢复孕前体重的比例，并在分娩后12个月减少产后体重潴留。方法将264例妊娠13.7周体重超重或肥胖妇女随机分为常规护理组和干预组。干预减少了妊娠期体重增加，并在分娩时停止。随访时，83.7%完成了12个月的评估。结果与常规护理相比，产前干预对12个月时达到孕前体重的几率（38/128[29.7%]比41/129 [31.8%],P = 0.98）和减轻体重的幅度（3.3比3.1 kg, P = 0.82）没有显著影响。分娩后，干预组的代餐量、体重控制行为和饮食限制均显著下降（P < 0.0001）。与组无关，较低的妊娠体重增加是12个月达到孕前体重的最强预测因子（P = 0.0008）。结论采用代餐的产前行为干预减少妊娠体重增加对产后12个月体重保持无显著影响。
Objective This randomized trial tested whether a behavioral intervention with meal replacements in pregnancy could increase the proportion of women who returned to prepregnancy weight and reduce postpartum weight retention by 12 months after delivery. Methods Women (N = 264; 13.7 weeks' gestation) with overweight or obesity were randomly assigned to usual care or intervention. The intervention reduced excess gestational weight gain and was discontinued at delivery. At follow-up, 83.7% completed the 12-month assessment. Results Compared with usual care, prenatal intervention had no significant effect on odds of achieving prepregnancy weight (38/128 [29.7%] vs. 41/129 [31.8%]; P = 0.98) or in reducing the magnitude of weight retained (3.3 vs. 3.1 kg; P = 0.82) at 12 months. After delivery, significant (P < 0.0001) declines in meal replacements, practice of weight control behaviors, and dietary restraint were observed in the intervention group. Independent of group, lower gestational weight gain was the strongest predictor of achieving prepregnancy weight at 12 months (P = 0.0008). Conclusions A prenatal behavioral intervention with meal replacements that reduced pregnancy weight gain had no significant effect on 12-month postpartum weight retention.
