Abstract

Median age of menarche was determined in children of European and Aymara ancestry residing in La Paz, Bolivia (3600 m) and in children of European ancestry residing in Santa Cruz, Bolivia (400 m). Median age of menarche in European and Aymara highland natives was younger than reported by previous researchers, thus broadening the range of variation in age of menarche in high-altitude populations. Comparisons between La Paz and Santa Cruz European children suggested that growth and development at high altitudes results in a delay in median age of menarche of about 0.8 years.

摘要

月经初潮的中位年龄是在居住于玻利维亚拉巴斯（海拔3600米）的欧洲和艾马拉血统儿童以及居住于玻利维亚圣克鲁斯（海拔400米）的欧洲血统儿童中确定的。欧洲和艾马拉高原原住民的月经初潮中位年龄比先前研究人员报告的要小，从而拓宽了高海拔人群月经初潮年龄的变化范围。拉巴斯和圣克鲁斯的欧洲儿童之间的比较表明，高海拔地区的生长发育会导致月经初潮中位年龄延迟约0.8岁。
