Low intakes by 198 pregnant women of milk, fruit, and vegetables are reported: consumption of meat and bread and cereals was satisfactory. However, mean hemoglobin and hematocrit values were within acceptable ranges for these women, indicating that supplementation apparently compensated in part for poor dietary habits. Protein intake of the infants of these mothers was above recommendations, the advisability of which is questioned. Height and weight of the male and female infants at birth were above and below the 10th percentile, respectively. By the age of four months, however, all infants were equal to or above this level. Mean hemoglobin levels were above acceptable levels.
据报告，198名孕妇牛奶、水果和蔬菜摄入量较低：肉类、面包和谷物的摄入量令人满意。然而，这些孕妇的平均血红蛋白和血细胞比容值在可接受范围内，这表明补充剂显然在一定程度上弥补了不良饮食习惯。这些母亲所生婴儿的蛋白质摄入量高于建议值，其合理性受到质疑。男婴和女婴出生时的身高和体重分别高于和低于第10百分位数。然而，到四个月大时，所有婴儿都达到或超过了这个水平。平均血红蛋白水平高于可接受水平。
