Women with excessive gestational weight gain are at increased risk of postpartum weight retention and potentially also unfavorable body composition. Insight into the lifestyle behaviors that play a role in the evolution of postpartum weight and body composition among these women could aid identification of those at highest risk of long-term adverse outcomes. This secondary analysis of the INTER-ACT randomized controlled trial investigates control group data only (n = 524). The evolution of weight retention, percentage loss of gestational weight gain, fat percentage, waist circumference, and associated lifestyle behaviors between 6 weeks and 12 months postpartum were assessed using mixed model analyses. At six weeks postpartum, every sedentary hour was associated with 0.1% higher fat percentage ( = 0.01), and a higher emotional eating score was associated with 0.2% higher fat percentage ( < 0.001) and 0.3 cm higher waist circumference ( < 0.001). Increase in emotional eating score between 6 weeks and 6 months postpartum was associated with a 0.4 kg ( = 0.003) increase in postpartum weight retention from six months onwards. Among women with overweight, an increase in the uncontrolled eating score between 6 weeks and 6 months postpartum was associated with a 0.3 kg higher postpartum weight retention ( = 0.04), and 0.3% higher fat percentage ( = 0.006) from six months onwards. In conclusion, sedentary and eating behaviors play important roles in postpartum weight and body composition of women with excessive gestational weight gain and should therefore be incorporated as focal points in lifestyle interventions for this population.
女性如果孕期体重增加过多，产后体重滞留和可能出现不良身体成分的风险会增加。了解在这些女性中导致产后体重和身体成分变化的生活方式行为，可以帮助确定那些长期不良结局风险最高的人。本研究是 INTER-ACT 随机对照试验的二次分析，仅分析对照组数据（n = 524）。使用混合模型分析评估了产后 6 周到 12 个月体重滞留、孕期体重增加损失百分比、体脂百分比、腰围的变化以及相关的生活方式行为。产后 6 周时，每久坐 1 小时，体脂百分比就会增加 0.1%（ = 0.01），而情绪性进食评分每增加 1 分，体脂百分比就会增加 0.2%（ < 0.001），腰围增加 0.3 厘米（ < 0.001）。产后 6 周到 6 个月期间情绪性进食评分的增加与产后体重滞留的增加有关，从 6 个月开始，体重滞留增加 0.4 公斤（ = 0.003）。在超重女性中，产后 6 周到 6 个月期间无法控制的进食评分增加与产后体重滞留增加 0.3 公斤（ = 0.04）和体脂百分比增加 0.3%（ = 0.006）有关。总之，久坐和进食行为在孕期体重增加过多的女性产后体重和身体成分中起着重要作用，因此应将其作为该人群生活方式干预的重点。
