The objective of the present study was to determine recalled age at menarche in women of Quechua and non-Quechua ancestry living in the cities of Lima (altitude 150 m), Cusco (altitude 3,400 m), and Cerro de Pasco (altitude 4,340 m), Perú. The sample included 296 Mestizo urban women, 20-30 years, who were natives of Lima (n = 72), Cusco (n = 81), and Cerro de Pasco (n = 143). Ethnic composition was determined by two parental surnames, and women were classified as Quechua when one or both surnames were of Quechua origin and non-Quechua when both surnames were of Spanish origin. Age at menarche was obtained by recall to nearest year. In Quechua as in non-Quechua women, age at menarche occurred later as residence altitude increased. Mean ages at menarche for the combined Quechua and non-Quechua samples were 13.1 ± 1.4 years in Lima, 13.9 ± 1.9 years in Cusco, and 14.6 ± 1.69 years in Cerro de Pasco. Thus age at menarche occurs later at high altitude independent of ethnic influence. © 1994 Wiley-Liss, Inc.
本研究的目的是确定居住在秘鲁利马市（海拔150米）、库斯科市（海拔3400米）和塞罗德帕斯科市（海拔4340米）的克丘亚族和非克丘亚族血统女性回忆起的初潮年龄。样本包括296名20至30岁的城市混血女性，她们分别来自利马（n = 72）、库斯科（n = 81）和塞罗德帕斯科（n = 143）。种族构成由父母的两个姓氏确定，当一个或两个姓氏为克丘亚族起源时，女性被归类为克丘亚族；当两个姓氏均为西班牙起源时，则被归类为非克丘亚族。初潮年龄通过回忆最近的年份来获取。在克丘亚族和非克丘亚族女性中，初潮年龄都随着居住海拔的升高而推迟。克丘亚族和非克丘亚族样本合并后的初潮平均年龄在利马为13.1±1.4岁，在库斯科为13.9±1.9岁，在塞罗德帕斯科为1,4.6±1.69岁。因此初潮年龄在高海拔地区出现得更晚，且不受种族影响。© 1994威利 - 利斯公司。
