Weight, triceps and subscapular skinfold measurements, and mean intakes of 11 nutrients and calories were evaluated for 102 pregnant women in four age groups. The increase in weight during the antepartum period was the only significant finding for anthropometric measurements. Comparison of antepartum group means showed the two younger groups, 12-17 and 18-19 years, had higher intakes of calories, protein, fat, carbohydrate, calcium, phosphorus, and iron than the two older groups, 20-24 and 25-32. The two older groups had higher mean intakes of vitamin A, thiamin, niacin, and ascorbic acid, most of them significantly so. In the postpartum period, there were no significant differences among age groups for mean intakes of calories, protein, fat, carbohydrate, or phosphorus. The two older groups had the higher mean intakes of the remaining nutrients. There were no significant differences among age groups for any of the nutrients with respect to level of education. Regardless of age, the subjects attending the low-cost clinic had a mean intake of iron significantly higher than those having private physicians, while the latter had a mean ascorbic acid intake significantly higher than that of the clinic group.
对四个年龄组的102名孕妇进行了体重、肱三头肌和肩胛下皮褶测量，以及11种营养素和卡路里的平均摄入量评估。孕期体重增加是人体测量方面唯一显著的发现。产前组均值比较显示，12 - 17岁和18 - 19岁这两个较年轻的组，在卡路里、蛋白质、脂肪、碳水化合物、钙、磷和铁的摄入量上高于20 - 24岁和25 - 32岁这两个较年长的组。两个较年长的组维生素A、硫胺素、烟酸和抗坏血酸的平均摄入量较高，其中大多数差异显著。产后阶段，各年龄组在卡路里、蛋白质、脂肪、碳水化合物或磷的平均摄入量上没有显著差异。两个较年长的组其余营养素的平均摄入量较高。在任何营养素方面，不同年龄组在教育水平上没有显著差异。无论年龄如何，在低成本诊所就诊的受试者铁的平均摄入量显著高于有私人医生的受试者，而后者抗坏血酸的平均摄入量显著高于诊所组。
