Excessive postpartum weight retention puts women at risk for health problems. This study aimed to investigate the effects of dairy foods on weight retention and risk of obesity in postpartum women in the Nurses’ Health Study II. Weight was reported every 2 years. We identified the pre-pregnancy and postpartum exams that were approximately 2 years before and after the birth year. Dairy consumption was averaged during these 4 years. Linear models were used to assess postpartum weight retention. Multivariable models were used to estimate risk of obesity. Women with higher yogurt (≥2 servings/week vs. <1 serving/month) intakes had 0.61 pounds less postpartum weight retention. Consuming ≥ 5 cheese servings/week was associated with 0.63 pounds less weight retention than the lowest intake. Among sedentary women, only yogurt intake was associated with lower risk of postpartum obesity (RR: 0.84; 95% CI: 0.71−1.00), though of borderline statistical significance. Among women with less healthy diets, yogurt consumption was also associated with lower postpartum obesity risk (RR: 0.70; 95% CI: 0.57−0.85). In sum, higher yogurt and cheese intakes were associated with less postpartum weight retention and among higher risk women (sedentary or lower diet quality) greater yogurt intake was associated with lower risks of postpartum obesity.
产后体重滞留过多会使妇女面临健康问题的风险。这项研究旨在调查在护士健康研究 II 中，乳制品对产后妇女体重滞留和肥胖风险的影响。体重每两年报告一次。我们确定了大约在出生前两年和出生后两年的孕前和产后检查。在这 4 年期间，平均计算了乳制品的摄入量。线性模型用于评估产后体重滞留。多变量模型用于估计肥胖风险。与每月食用<1 份酸奶（≥2 份/周）相比，摄入更多酸奶（≥2 份/周）的女性产后体重滞留减少了 0.61 磅。与最低摄入量相比，每周食用≥5 份奶酪与减少 0.63 磅体重滞留相关。在久坐不动的女性中，只有酸奶摄入量与较低的产后肥胖风险相关（RR：0.84；95%CI：0.71−1.00），尽管具有边缘统计学意义。在饮食不健康的女性中，酸奶的摄入量也与较低的产后肥胖风险相关（RR：0.70；95%CI：0.57−0.85）。总之，较高的酸奶和奶酪摄入量与产后体重滞留减少有关，而对于高风险女性（久坐不动或饮食质量较低），摄入更多的酸奶与较低的产后肥胖风险相关。
