Babies born at altitudes above 2,700 meters have been reported to be below normal birth weight and small for gestational age (SGA). In a study of a specific community (Leadville, Colorado, altitude 3,100 meters) over a period of 14 months (ending November, 1978), 215 newborn infants were found to be appropriate for gestational age (AGA), with the entire group having a mean birth weight (3.16 kilograms) similar to that of newborn infants in Denver, Colorado (3.12 kilograms). This study from a community with a stable population indicates that babies born at high altitude are AGA. The increased morbidity which does occur for these babies is not due to SGA factors.
据报道，出生在海拔2700米以上的婴儿出生体重低于正常水平且小于胎龄（SGA）。在一项对特定社区（科罗拉多州莱德维尔，海拔3100米）为期14个月（截至1978年11月）的研究中，发现215名新生儿为适于胎龄儿（AGA），整个群体的平均出生体重（3.16千克）与科罗拉多州丹佛市的新生儿平均出生体重（3.12千克）相似。这项来自人口稳定社区的研究表明，在高海拔地区出生的婴儿为AGA。这些婴儿确实出现的发病率增加并非由于小于胎龄因素。
