背景资料：怀孕期间体重增加而产后体重没有减轻可能导致育龄妇女肥胖。目的：我们的目的是确定母乳喂养是否会降低完全母乳喂养常见且母乳喂养持续时间长的人群的产后体重保留（PPWR）。设计：我们从丹麦国家出生队列中选择了母乳喂养的妇女（> 98%），在产后6个月（n = 36030）和18个月（n = 26846）进行访谈。我们使用回归分析来研究在调整母亲孕前体重指数（BMI）和妊娠期体重增加（GWG）后，母乳喂养（根据持续时间和强度进行评分）是否会降低产后6个月和18个月的PPWR。除孕前体重指数最重的妇女产后6个月（P < 0.0001）和18个月（P < 0.05）外，所有妇女的母乳喂养与PPWR呈负相关。当与可能的混杂因素调整一起建模时，这些相关性略有减弱。我们计算出，如果妇女完全母乳喂养6个月的建议，PPWR可以消除的时候，妇女与GWG值接近12公斤，并可能主要的体重增加（>= 5公斤），可以减少在所有，但最重的women.Conclusion：母乳喂养与较低的PPWR在所有类别的孕前BMI。这些结果表明，当结合GWG值约12公斤，母乳喂养的建议，可以消除许多妇女产后6个月的体重保留。美国临床营养杂志2008; 88：1543-51。
Background: Weight gained during pregnancy and not lost postpartum may contribute to obesity in women of childbearing age.Objective: We aimed to determine whether breastfeeding reduces postpartum weight retention (PPWR) in a population among which full breastfeeding is common and breastfeeding duration is long.Design: We selected women from the Danish National Birth Cohort who ever breastfed (> 98%), and we conducted the interviews at 6 (n = 36 030) and 18 (n = 26 846) mo postpartum. We used regression analyses to investigate whether breastfeeding (scored to account for duration and intensity) reduced PPWR at 6 and 18 mo after adjustment for maternal prepregnancy body mass index (BMI) and gestational weight gain (GWG).Results: GWG was positively (P < 0.0001) associated with PPWR at both 6 and 18 mo postpartum. Breastfeeding was negatively associated with PPWR in all women but those in the heaviest category of prepregnancy BMI at 6 (P < 0.0001) and 18 (P < 0.05) mo postpartum. When modeled together with adjustment for possible confounding, these associations were marginally attenuated. We calculated that, if women exclusively breastfed for 6 mo as recommended, PPWR could be eliminated by that time in women with GWG values of approximate to 12 kg, and that the possibility of major weight gain (>= 5 kg) could be reduced in all but the heaviest women.Conclusion: Breastfeeding was associated with lower PPWR in all categories of prepregnancy BMI. These results suggest that, when combined with GWG values of approximate to 12 kg, breastfeeding as recommended could eliminate weight retention by 6 mo postpartum in many women.
