To study the effects of lifestyle intervention in pregnancy on weight retention 6 months postpartum among obese women from the "Lifestyle in Pregnancy" (LiP) study, and to determine associations between breastfeeding with postpartum maternal weight.
Six months postpartum follow up after a randomized controlled intervention trial.
Two university hospitals in Denmark.
A total of 360 women with pregestational body mass index ≥30 kg/m(2) .
The intervention involved lifestyle changes (diet and exercise) during pregnancy. The control group received routine pregnancy care. Both groups received standard postnatal care.
Gestational weight gain, postpartum weight retention and breastfeeding.
Follow up was completed in 238 women of whom 46% in the intervention group and 57% in the control group had retained weight 6 months postpartum (p = 0.088). Women with gestational weight gain ≤9 kg, (recommended by the Institute of Medicine), retained less postpartum weight compared with those who exceeded 9 kg (median -0.7 vs. 1.5, p < 0.001). Ninety-two percent in both weight gain groups initiated breastfeeding. The number of breastfeeding mothers was higher among women with postpartum weight retention ≤5 kg compared with those with weight retention > 5 kg (94% vs. 85%, p = 0.034).
We could not detect sustained weight control at 6 months postpartum despite a lower gestational weight gain for obese women during pregnancy who received a lifestyle intervention rather than standard care. Women who adhered to gestational weight gain recommendations had significantly lower postpartum weight retention. Breastfeeding for 6 months was negatively associated with postpartum weight retention.
通过“孕期生活方式”（LiP）研究，探讨孕期生活方式干预对肥胖女性产后6个月体重保留的影响，并确定母乳喂养与产后母亲体重之间的关联。
随机对照干预试验后进行产后6个月随访。
丹麦的两家大学医院。
共有360名孕前体重指数≥30kg/m²的女性。
干预措施包括孕期生活方式改变（饮食和运动）。对照组接受常规孕期护理。两组均接受标准产后护理。
孕期体重增加、产后体重保留和母乳喂养情况。
238名女性完成随访，其中干预组46%、对照组57%在产后6个月体重有所保留（p = 0.088）。孕期体重增加≤9kg（医学研究所推荐）的女性，产后体重保留比超过9kg的女性少（中位数-0.7 vs. 1.5，p < 0.001）。两个体重增加组中92%的女性开始母乳喂养。产后体重保留≤5kg的女性中母乳喂养的母亲数量高于体重保留>5kg的女性（94% vs. 85%，p = 0.034）。
尽管接受生活方式干预而非标准护理的肥胖女性孕期体重增加较少，但我们在产后6个月未检测到持续的体重控制。遵循孕期体重增加建议的女性产后体重保留明显较低。母乳喂养6个月与产后体重保留呈负相关。
