通过对健康婴儿1周岁生长发育和蛋白质营养的前瞻性跟踪，研究纯母乳喂养的营养充分性。纯母乳喂养的婴儿在6个月时为116个，9个月时为36个。这些婴儿在3个月后的长度速度比32名早期断奶并给予配方奶加固体的婴儿的对照组慢。作为一个整体，纯母乳喂养的婴儿在相对长度上稍微落后，但逐渐落后。到9个月时，45%的患者相对于对照组18%的患者显示出相对长度减少了10个月。在相对体重方面没有发现这种减少。皮肤褶皱和体重长度指数显示，他们的体重比比较婴儿重。在6点和9点时，计算的蛋白质摄入量（0.9 g/kg/天）远低于推荐量（2.0 g/kg/天）。血清白蛋白前浓度低于对照组，但早在4个月时就注意到了这一点。无论是单独还是总体上，生长参数与蛋白质营养之间都没有关系。纯母乳喂养婴儿的生长速度较慢是否代表了适当的生理生长，还是表明营养缺乏，目前尚不清楚，但没有证据表明蛋白质缺乏。然而，有6名婴儿表现出随后的追赶生长，这可能表明他们之前营养不良。
The nutritional adequacy of exclusive breast-feeding was studied by following prospectively the growth and protein nutrition of healthy infants during the 1st yr of life. The number of exclusively breast-fed infants was 116 at the age of 6 mo. and 36 at 9 mo. These infants had slower length velocity after age 3 mo. than a comparison group of 32 infants who were weaned early and given formula plus solids. As a group, the exclusively breast-fed infants lagged slightly, but progressively, behind in relative length. By 9 mo. 45% of them vs. 18% of the comparison group showed a > 1 SD decrease in relative length. No such decrease was found in relative weight. Skinfolds and weight for length2 index showed that they were heavier for their length than the comparison infants. At 6 and 9 mo. the calculated protein intake (0.9 g/kg/day) was much less than the recommended amount (2.0 g/kg/day). Serum prealbumin concentration was lower than in the comparison group but this was noted as early as 4 mo. No relation was found between the parameters of growth and protein nutrition either individually or in general. Whether the slower growth of the exclusively breast-fed infants represents appropriate physiological growth or whether it indicates nutritional deficiency is not known but no evidence of protein deficiency. Six infants did, however, show subsequent catch-up growth which could indicate previous malnutrition.
