To evaluate the effect of altitude on adolescent growth and development, three groups of healthy, well-nourished youth of similar socioeconomic status and ethnic grouping who resided at sea level (n = 1262 subjects), mid-altitude (n = 1743 subjects), and high altitude (n = 1137 subjects) were studied. The following parameters were evaluated: weight and height in all subjects; genital and pubic hair development in the males; and the initiation of breast development and age of menarche in the females. At mid-altitude, puberty appears to start at a similar age, but lasts longer, than at sea level. At high altitude, puberty starts significantly later and is more prolonged than at sea level and mid-altitude. Our data reveal relatively little effect of altitude upon growth and weight-gain patterns or final attained heights and weights.
为评估海拔高度对青少年生长发育的影响，研究了三组社会经济地位和种族分组相似、健康且营养良好的青年，他们分别居住在海平面（1262名受试者）、中等海拔（1743名受试者）和高海拔（1137名受试者）地区。评估了以下参数：所有受试者的体重和身高；男性的生殖器和阴毛发育；女性乳房发育的开始时间和月经初潮年龄。在中等海拔地区，青春期开始的年龄似乎与海平面地区相似，但持续时间更长。在高海拔地区，青春期开始的时间明显更晚，且比海平面和中等海拔地区持续时间更长。我们的数据显示，海拔高度对生长、体重增加模式或最终达到的身高和体重影响相对较小。
