The influence of height and delivery weight (pregravid and gestational gain), expressed as percent ideal weight for height, upon birth weight was examined in 696 uncomplicated term pregnancies. Each gravida was classified by delivery weight as short, average, or tall. Mean infant birth weight paralleled increasing maternal delivery weight percent in all three height groups, although the effect was most pronounced among gravidas of short stature (r = +0.997). In that group, a 10% increase in delivery weight was reflected by an increase of 127 gm in mean infant birth weight. Among gravidas of average stature, a 10% increase in delivery weight resulted in an increase of 74 gm in mean infant birth weight (r = +0.983). A 10% increase in delivery weight among gravidas of tall stature resulted in an increase of 87 gm in mean infant birth weight (r = +0.938). The incidence of both severe and moderate intrauterine growth retardation was found to be inversely proportional to increasing delivery weight percent among gravidas of short and average stature. Adequate pregravid weight and liberal gains appeared to augment optimal growth in all gravidas studied but were of particular benefit to the infant of the short gravida.
在696例无并发症的足月妊娠中，研究了身高和分娩体重（孕前体重和孕期体重增加）以身高理想体重百分比表示对出生体重的影响。每位孕妇按分娩体重分为矮、中、高三个类别。在所有三个身高组中，平均婴儿出生体重均与产妇分娩体重百分比的增加呈平行关系，尽管这种影响在身材矮小的孕妇中最为明显（r = +0.997）。在该组中，分娩体重增加10%，平均婴儿出生体重增加127克。在中等身材的孕妇中，分娩体重增加10%，平均婴儿出生体重增加74克（r = +0.983）。身材高大的孕妇分娩体重增加10%，平均婴儿出生体重增加87克（r = +0.938）。发现身材矮小和中等身材的孕妇中，重度和中度宫内生长迟缓的发生率与分娩体重百分比的增加呈反比。充足的孕前体重和大量的体重增加似乎促进了所有研究孕妇的最佳生长，但对身材矮小孕妇的婴儿尤其有益。
