The association between maternal weight gain during pregnancy and the infant's birth weight was studied in 14,121 term singleton births. The parturients were stratified into four body-mass categories, three age groups, four parity groups, and three levels of educational attainment. A separate multiple regression analysis was performed for each category to control for the confounding effect of gestational age, maternal social class, ethnicity, cigarette consumption, marital status, age, parity, education, and weight for height. A significant positive influence of prenatal weight gain on birth weight was found for all subgroups. The effect varied depending on maternal pre-pregnancy body mass, age, parity, and the level of formal education.
在14121例足月单胎分娩中研究了孕期母亲体重增加与婴儿出生体重之间的关联。将产妇分为四个体重类别、三个年龄组、四个产次组和三个教育程度水平。对每个类别分别进行多元回归分析，以控制孕周、母亲社会阶层、种族、吸烟量、婚姻状况、年龄、产次、教育程度和身高体重等混杂因素的影响。在所有亚组中均发现产前体重增加对出生体重有显著的正向影响。其影响因母亲孕前体重、年龄、产次和正规教育水平的不同而有所差异。
