Three hundred and thirty two pregnant women who were attending three antenatal clinics in Morogoro Municipality in Tanzania were followed in their third trimester of pregnancy in a study which aimed at finding if there was any association between weight gain in third trimester and birth weight of singleton deliveries. The relationship between weight and gestational period, age of the mother, parity and maternal weight near term were also studied. Univariate regression analysis showed that there was a strong positive correlation between birth weight and gestational period. Correlation was also found between birth weight and age of the mother, parity and weight near term, while a week correlation was found between birth weight and maternal weight gain in the third trimester. Multiple regression analysis showed that only the gestation period and weight near term were independently related to birth weight. Despite low maternal weight gain, birth weight was not affected, this shows that there might be some physiological adaptation which come into play to protect the foetus where a woman is subjected to inadequate nutrition during pregnancy.
在坦桑尼亚莫罗戈罗市的三家产前诊所就诊的332名孕妇在妊娠晚期接受了跟踪调查，该研究旨在探究妊娠晚期体重增加与单胎分娩出生体重之间是否存在关联。同时还研究了体重与妊娠期、母亲年龄、产次以及孕晚期母亲体重之间的关系。单变量回归分析表明，出生体重与妊娠期之间存在强正相关。出生体重与母亲年龄、产次和孕晚期体重之间也存在相关性，而出生体重与妊娠晚期母亲体重增加之间的相关性较弱。多元回归分析表明，只有妊娠期和孕晚期体重与出生体重独立相关。尽管母亲体重增加较少，但出生体重并未受到影响，这表明在孕期女性营养不足的情况下，可能会有一些生理适应机制发挥作用来保护胎儿。
