The growth of 79 healthy, well-nourished lowland (400 M) and highland (3600 M) Bolivian infants was analyzed in a longitudinal study through the first postnatal year. Compared to low altitude infants, the high altitude infants were found, by analysis of covariance controlling for size at the previous exam, to be significantly shorter at birth, 1 and 6 months, while they were significantly lighter only at birth and 1 year. Recumbent length gain was slower in the high altitude infants in the early months of life, while weight gain did not differ between altitudes. The observed lower weights at high altitude throughout the first year appear to be due to a persistence of lower weights seen at birth and not to postnatal growth retardation. Significantly greater triceps and subscapular skinfold thickness measurements were found in the highland group, despite their smaller length and weight. The possible causes and implications of the greater fat accumulation in the highland infants are discussed.
在一项纵向研究中，对79名健康、营养良好的玻利维亚低地（海拔400米）和高地（海拔3600米）婴儿出生后第一年的生长情况进行了分析。通过协方差分析对上次检查时的体型进行控制后发现，与低海拔婴儿相比，高海拔婴儿在出生时、1个月和6个月时明显更矮，而仅在出生时和1岁时明显更轻。在生命的最初几个月里，高海拔婴儿的仰卧身长增长较慢，而体重增长在不同海拔之间没有差异。在第一年中观察到的高海拔地区较低体重似乎是由于出生时体重较低的持续存在，而不是由于出生后生长发育迟缓。尽管高地组婴儿的身长和体重较小，但发现他们的肱三头肌和肩胛下皮褶厚度测量值明显更大。讨论了高地婴儿脂肪堆积较多的可能原因及其影响。
