Excess postpartum weight retention (PPWR) is related to long-term weight gain. Therefore, this study was conducted to identify the risk factors for PPWR to provide guidance for preventive strategies.
This cohort study surveyed 461 women who gave birth at a medical center between March 2014 and March 2016. The participants completed a questionnaire within 1 month of delivery, and their 6-month postpartum weight was tracked.
The results showed that the mean pre-pregnancy BMI was 21.4 ± 3.3 kg/m2, and the mean gestational weight gain (GWG) was 12.8 ± 4.1 kg. The mean PPWR was 4.6 ± 3.5 kg at 1 month and 2.1 ± 3.3 kg at 6 months. Multivariate analysis revealed that GWG (adjusted OR: 1.92 (1.70-2.17)), pre-pregnancy BMI (adjusted OR: 0.85 (0.77-0.94)), and exclusive breastfeeding (adjusted OR: 0.55 (0.32-0.94)) were significantly correlated with a 1-month PPWR higher than the median value. In addition, GWG (adjusted OR: 1.30 (1.22-1.39)) and exclusive breastfeeding (adjusted OR: 0.37 (0.24-0.58)) were significantly correlated with a 6-month PPWR higher than the median value.
Our findings indicate that the key to reducing PPWR is to control GWG and engage in exclusive breastfeeding.
产后体重滞留过多(PPWR)与长期体重增加有关。因此,本研究旨在确定 PPWR 的风险因素,为预防策略提供指导。
本队列研究调查了 2014 年 3 月至 2016 年 3 月在一家医疗中心分娩的 461 名妇女。参与者在分娩后 1 个月内完成了一份问卷,并跟踪了她们产后 6 个月的体重。
结果显示,参与者的孕前 BMI 平均值为 21.4 ± 3.3 kg/m2,妊娠期体重增加(GWG)平均值为 12.8 ± 4.1 kg。1 个月时的平均 PPWR 为 4.6 ± 3.5 kg,6 个月时为 2.1 ± 3.3 kg。多变量分析显示,GWG(调整后的 OR:1.92(1.70-2.17))、孕前 BMI(调整后的 OR:0.85(0.77-0.94))和纯母乳喂养(调整后的 OR:0.55(0.32-0.94))与 1 个月时 PPWR 高于中位数显著相关。此外,GWG(调整后的 OR:1.30(1.22-1.39))和纯母乳喂养(调整后的 OR:0.37(0.24-0.58))与 6 个月时 PPWR 高于中位数显著相关。
我们的研究结果表明,降低 PPWR 的关键是控制 GWG 和进行纯母乳喂养。
