| 摘 要： | 目的：分析我国11~18岁汉族男生肥胖与首次遗精年龄的相关性。方法：从2010年全国体质调研数据中选取11~18岁汉族男生的身高、体重、遗精报告情况，计算体质指数（body mass index，BMI）， 采用概率单位回归法计算半数首次遗精年龄。采用卡方检验分析11~18岁不同营养状况与遗精报告率的相关性， 采用U检验比较肥胖组与非肥胖组半数首次遗精年龄的差异。结果：在城市男生12岁和17岁年龄组，乡村男生13岁年龄组，不同营养状况之间的遗精报告率差异有统计学意义（P<0.05）。半数首次遗精年龄在肥胖组和非肥胖组间差异具有统计学意义，肥胖组（13.90岁）较非肥胖组（14.00岁）提前（P<0.05）。结论：肥胖可能使男生首次遗精年龄提前。

| Abstract: | Objective:To analyze the association between obesity and age at spermarche among Chinese Han boys aged 11-18 years . Methods:The height, weight and status of the spermarche of Chinese Han boys aged 11-18 years were selected from the data of 2010 National Physical Fitness and Health Surveil-lance. The body mass index ( BMI) , prevalence of spermarche in each age group and ages at spermarche by BMI groups were calculated. Chi square test was used to analyze the differences of prevalences of spermarche among the boys with different BMIs across ages. U-test was used to compare the differences of age at spermarche between the boys who were obese and not. Results:In the boys aged 12 and 17 years in urban areas and boys aged 13 years in rural areas, the differences of prevalences of spermarche among the normal weight, overweight and obesity groups were significant (P<0. 05). The age at spermarche in the obesity group (13. 90 years) was 0. 1 years earlier than that in the non-obesity group (14. 00 years) (P<0. 05). Conclusion:Obesity may make the age at spermarche ahead of time. |
