Some women in rural Pakistan are chronically undernourished, and consequently underweight. Concerns have been expressed that the degree of undernourishment might be sufficiently severe to affect lactation performance. We have obtained data on maternal body composition and infant breast milk intake using stable isotope methods in a group of thirty three mother and infant pairs at approximately six months of age. The maternal body mass index ranged from 16.6 to 29.1 kg·m(-2). In this population we found that exclusive breast-feeding tended to be associated with lower maternal body fat, and that there was no evidence for compromised lactational performance due to malnourishment. Finally we note that when our data is combined with that from other studies there may be a generalised negative correlation between breast milk intake and maternal body fat.
巴基斯坦农村的一些妇女长期营养不良,因此体重不足。有人担心营养不良的程度可能严重到足以影响泌乳表现。我们使用稳定同位素方法,在一组约6个月大的33对母婴中获取了母亲身体成分和婴儿母乳摄入量的数据。母亲的体重指数范围为16.6至29.1 kg·m(-2)。在这个群体中,我们发现纯母乳喂养往往与较低的母亲体脂有关,而且没有证据表明营养不良会损害泌乳表现。最后,我们注意到,当我们的数据与其他研究的数据相结合时,母乳摄入量与母亲体脂之间可能存在普遍的负相关。
