对56例产妇从分娩到产后6个月的体重和体脂变化进行了研究。纯母乳喂养(BF)、纯配方奶粉喂养(FF)以及母乳和配方奶混合喂养母亲(CF)的6个月体重减少量(p<；0.01)为8.30+-。0.74，8.19。+-。0.96和7.22。+-。0.74 kg，但只有BF在3~6个月有显著变化。在6个月内，髂上和肩胛下皮褶厚度减少(p<；0.01)，其中髂上区域反映了显着的喂食法效应。3个月时三头肌脂肪厚度的增加表明，随着孕期能量储备的调动，体脂发生了暂时的重新分配。哺乳期母亲摄入更多(P<；0.01)千卡(BF，2055.+-)。435；对比文件，2005年。+-。515)，而非哺乳期母亲(FF，1453.+-)。503)。年龄、胎次和孕前体重具有显著的协变量效应。结果表明，哺乳确实对产后体重和体脂减少起到了作用，但目前的RDA可能太高了，不允许这样的减少。
Maternal weight and body fat changes were studied in 56 women from delivery to 6 mo postpartum. Six-month weight losses (p < 0.01) in exclusively breast-feeding (BF), exclusively formula-feeding (FF), and combination breast- and formula-feeding mothers (CF) were 8.30 .+-. 0.74, 8.19 .+-. 0.96, and 7.22 .+-. 0.74 kg respectively; however, only BF experienced a significant change between 3 and 6 mo. Suprailiac and subscapular skinfold thickness decreased over 6 mo (p < 0.01) with the suprailiac region reflecting a significant feeding-method effect. Increases in triceps fatfold measurements at 3 mo suggest that a temporary redistribution of body fat occurs as the energy stores of pregnancy are mobilized. Lactating mothers consumed more (p < 0.01) kilocalories (BF, 2055 .+-. 435; CF, 2005 .+-. 515) than did nonlactating mothers (FF, 1453 .+-. 503). Age, parity, and prepregnancy weight exerted significant covariable effects. Results suggest that lactation does play a role in postpartum weight and body fat loss but that the current RDA may be too high to permit such losses.
