测量了50名冈比亚农村妇女怀孕期间的体脂增加（体重-总身体水分/0.73），这些妇女暴露于自给农业的季节性能量需求和每年收获前的粮食短缺。28名妇女接受了先前显示会增加出生体重的膳食补充剂。在未补充的妇女中，脂肪增加受到怀孕进展的季节的深刻影响，在一年中的不同时间，估计损失4.7公斤到净增加3公斤。然而，季节调整显示，怀孕本身对体脂含量没有影响。补充增加怀孕期间的脂肪增加约2 kg（p < 0.05），并能保护机体免受季节对能量平衡的最坏影响。这些发现有助于我们理解1）怀孕期间食物摄入量低的后果和2）膳食补充剂对出生体重的影响。
Body-fat gain during pregnancy (weight-total body water/0.73) was measured in 50 rural Gambian women exposed to seasonal energy demands of subsistence farming and to annual preharvest food shortages. Twenty-eight women received dietary supplements in amounts previously shown to increase birth weight. In unsupplemented women, fat gain was profoundly affected by the seasons through which the pregnancy progressed, ranging from an estimated loss of 4.7 kg to a net gain of 3 kg at various times of the year. Adjustment for season revealed, however, that pregnancy per se was without effect on body fat content. Supplementation increased fat gain during pregnancy by .apprx. 2 kg (p < 0.05) and gave protection against the worst effects of season on energy balance. These findings contribute to our understanding of 1) the consequences of low food intake during pregnancy and 2) the effects of dietary supplementation on birth weight.
