Information on breast-feeding was obtained from 25 mothers recruited from four high school programs for teenaged parents. Subjects were visited monthly 1-9 times (mean 3.7 visits) during the first 10 months of lactation to measure infant growth and maternal dietary intake and to collect a breast milk sample. Of 24 mothers visited more than once, 21 (88%) breast-fed for more than 3 months, and at least nine continued beyond 6 months. Compared to the nutrient content of milk samples from adult women, milk of teenage mothers was significantly lower in lactose, magnesium, calcium, potassium, and sodium. However, the differences in magnesium, calcium, and potassium may have been due to differences in the timing of sample collection. On the basis of infant growth, milk volume was judged to be adequate for 88% of the infants. Mean maternal energy and protein intakes were 2,897 kcal and 115 g, respectively; mean intakes of calcium, potassium, vitamin A, riboflavin, niacin, and vitamin C exceeded the National Research Council's Recommended Dietary Allowances (RDA) for lactation, while iron and thiamine intakes averaged 84% and 94% of the RDA, respectively. It is concluded that with active counseling teenage mothers are capable of successful lactation.
关于母乳喂养的信息来自于从四个针对青少年父母的高中项目中招募的25位母亲。在哺乳期的前10个月，每月对研究对象进行1至9次（平均3.7次）访视，以测量婴儿生长情况、母亲的膳食摄入量，并采集母乳样本。在接受多次访视的24位母亲中，21位（88%）母乳喂养超过3个月，至少9位持续到6个月以后。与成年女性的母乳样本营养成分相比，青少年母亲的母乳中乳糖、镁、钙、钾和钠的含量显著较低。然而，镁、钙和钾的差异可能是由于样本采集时间不同所致。根据婴儿生长情况判断，88%的婴儿母乳量充足。母亲的能量和蛋白质平均摄入量分别为2897千卡和115克；钙、钾、维生素A、核黄素、烟酸和维生素C的平均摄入量超过了美国国家研究委员会推荐的哺乳期膳食摄入量（RDA），而铁和硫胺素的摄入量分别平均为RDA的84%和94%。研究得出结论，通过积极的咨询指导，青少年母亲能够成功进行母乳喂养。
