【摘要】：目的了解蒙古族学生性发育状况,以便为青春期健康教育工作提供依据。方法选择7~18岁蒙古族学生,采用概率单位回归法和逐步回归分析,研究蒙古族学生月经初潮和首次遗精平均年龄及其与体质的关系。结果蒙古族女生初潮最早年龄城、乡均为10岁;全部来潮年龄城市为16岁,乡村18岁仍未达100%。初潮平均年龄城、乡分别为12.96和13.44岁,城市较乡村早0.48岁。男生最早首次遗精年龄城、乡均为11岁;全部首次遗精年龄城市男生18岁,乡村男生18岁尚未达100%。首次遗精平均年龄城乡分别为14.14与15.15岁,城市较乡村早了1.01岁。月经初潮和首次遗精均比全国平均年龄晚。结论蒙古族学生月经初潮和首次遗精平均年龄及最早发生年龄存在提前趋势。形态发育指标与青春期发育有密切关系。
[Abstract]:Objective to investigate the sexual development of Mongolian students in order to provide basis for adolescent health education. Methods the average age of menarche and first spermatozoa and their relationship with physical constitution were studied by using probabilistic unit regression and stepwise regression analysis. Results the earliest menarche age of Mongolian girls was 10 years old in rural areas, 16 years old in urban areas, and 100 years old in rural areas. The average age of menarche was 12.96 and 13.44 years in town, and 0.48 years earlier in urban than in rural area. The first spermatozoa of male students was 11 years old in the countryside, 18 years old for the first time spermatozoa, and 100 years old for the boys in the countryside. The average age of the first spermatozoa in urban and rural areas was 14.14 and 15.15 years respectively, and 1.01 years earlier in urban than in rural areas. Menarche and first spermatozoa were later than the national average age. Conclusion the average age and the earliest onset age of menarche and first spermatozoa of Mongolian students are early. There is a close relationship between morphological development index and puberty development.
