比较了母乳喂养（BF，n = 46）或配方奶喂养（FF，n = 41）的婴儿在1至24个月之间的人体测量指标，直至大于或等于12个月。两组均未在4个月前进食固体食物。7 ~ 24个月的FF婴儿的身高体重比显著更大。在两组中，皮褶厚度（三头肌、二头肌、肩胛下肌、侧腹肌和四头肌）和估计的体脂百分比（%FAT）在前6-8个月迅速增加，此后下降。在除二头肌外的所有部位，FF婴儿在婴儿后期（特别是9-15个月）的皮褶厚度均大于BF婴儿; %FAT在5 - 24个月显著较高。BF婴儿的能量摄入量较低解释了组间的差异。在12-24个月时，母亲和婴儿的肥胖呈正相关。母乳脂肪和能量浓度与婴儿肥胖无关。这些结果表明，婴儿BF大于或等于12个月是瘦比他们的FF同行。
Anthropometric indexes from 1 to 24 mo were compared between matched cohorts of infants either breast-fed (BF, n = 46) or formula-fed (FF, n = 41) until greater-than-or-equal-to 12 mo. Neither group received solid foods before 4 mo. Weight-for-length was significantly greater among FF infants from 7 to 24 mo. In both groups, skinfold thickness (triceps, biceps, subscapular, flank, and quadriceps) and estimated percent body fat (%FAT) increased rapidly during the first 6-8 mo and declined thereafter. At all sites except biceps, FF infants had larger skinfold thicknesses in later infancy (particularly 9-15 mo) than did BF infants; %FAT was significantly higher from 5 to 24 mo. Lower energy intake among BF infants explained the difference between groups. Maternal and infant fatness were positively correlated at 12-24 mo. Breast-milk lipid and energy concentration were unrelated to infant fatness. These results indicate that infants BF for greater-than-or-equal-to 12 mo are leaner than their FF counterparts.
