Postpartum weight retention is associated with adverse health among both civilian and military women.
The current study evaluated a stepped-care weight management intervention, Moms Fit 2 Fight, adapted for use in a pregnant and postpartum military population.
Active duty women and other TRICARE beneficiaries (N = 430) were randomized to one of three conditions: gestational weight gain only (GWG-only) intervention (n =144), postpartum weight loss only (PPWL-only) intervention (n =142), or a combined GWG + PPWL intervention (n = 144). Those participants who received the PPWL intervention (i.e., the PPWL-only and GWG+PPWL conditions) were combined consistently with the pre-registered protocol and compared to those participants who did not receive the PPWL intervention in the primary analyses. Primary outcome data (i.e., postpartum weight retention) were obtained at 6-months postpartum by unblinded data collectors, and intent-to-treat analyses were conducted.
Retention at 6-months postpartum was 88.4%. Participants who received the PPWL intervention retained marginally less weight (1.31 kg) compared to participants that received the GWG-only intervention (2.39 kg), with a difference of 1.08 kg (p = .07). None of the measured covariates, including breastfeeding status, were significantly associated with postpartum weight retention. Of the participants who received the PPWL intervention, 48.1% participants returned to their pre-pregnancy weight at 6-months postpartum, with no significant differences compared to those who received the GWG-only intervention.
A behavioral intervention targeting diet and physical activity during the postpartum period had a trend for reduced postpartum weight retention.
The trial is registered on clinicaltrials.gov (NCT03057808).
产后体重滞留与平民和军人女性的健康不良有关。
本研究评估了一种针对怀孕和产后军人人群的分步式体重管理干预措施，即 Moms Fit 2 Fight。
现役女性和其他 TRICARE 受益人（N=430）被随机分为以下三种条件之一：仅妊娠体重增加（GWG-only）干预组（n=144）、仅产后体重减轻（PPWL-only）干预组（n=142）或 GWG+PPWL 联合干预组（n=144）。那些接受 PPWL 干预的参与者（即 PPWL-only 和 GWG+PPWL 条件）与预先注册的方案一致，在主要分析中与未接受 PPWL 干预的参与者进行比较。产后 6 个月时，由未设盲的数据收集者获取主要结局数据（即产后体重滞留），并进行意向治疗分析。
产后 6 个月的保留率为 88.4%。接受 PPWL 干预的参与者比接受 GWG-only 干预的参与者体重滞留减少了 1.31 公斤，差值为 1.08 公斤（p=0.07）。包括母乳喂养状况在内的所有测量的协变量均与产后体重滞留无显著相关性。在接受 PPWL 干预的参与者中，48.1%的人在产后 6 个月时体重恢复到怀孕前的水平，与接受 GWG-only 干预的人相比没有显著差异。
针对产后期间饮食和身体活动的行为干预措施有降低产后体重滞留的趋势。
该试验在 clinicaltrials.gov 上注册（NCT03057808）。
