This study analyzed the effects of gestational weight gain and breastfeeding on postpartum weight retention. The study followed 2,607 women from the BRISA cohort. The variables were age, socioeconomic status, parity, pre-gestational body mass index, gestational weight gain, duration of maternal breastfeeding, length of postpartum follow-up, and postpartum weight gain. Structural equation modeling was used to evaluate the total, direct, and indirect effects of the explanatory variables on postpartum weight retention. An increase of one standard deviation in gestational weight gain corresponded to a significant increase of 0.49 standard deviations in postpartum weight retention (p < 0.001). An increase of one standard deviation in duration of breastfeeding corresponded to mean decrease of 0.10 standard deviations in postpartum weight retention (p < 0.001). Independently of pre-gestational BMI, gestational weight gain is a risk factor and duration of breastfeeding is a protective factor against postpartum weight retention.
本研究分析了孕期体重增加和母乳喂养对产后体重滞留的影响。该研究对来自BRISA队列的2607名女性进行了跟踪调查。变量包括年龄、社会经济地位、产次、孕前体重指数、孕期体重增加、母乳喂养持续时间、产后随访时长以及产后体重增加情况。采用结构方程模型来评估解释变量对产后体重滞留的总体、直接和间接影响。孕期体重增加每增加一个标准差，产后体重滞留就显著增加0.49个标准差（p < 0.001）。母乳喂养持续时间每增加一个标准差，产后体重滞留平均减少0.10个标准差（p < 0.001）。独立于孕前体重指数，孕期体重增加是产后体重滞留的一个风险因素，而母乳喂养持续时间是预防产后体重滞留的一个保护因素。
