摘要

摘要: 目的探索2019年宁夏地区11~18岁男生肥胖与首次遗精的相关性，为肥胖与青春期发育相关研究提供理论依据。方法采用分层随机整群抽样方法，于2019年选取宁夏回族自治区银川市、中卫市、吴忠市、固原市11~18岁男生5 240名，提取调查数据中身高、体重及是否发生首次遗精3个指标，计算体质量指数(BMI)来判断营养状况，采用χ²检验比较各营养状况组间差异；用概率单位回归法计算半数遗精年龄，运用U检验比较城乡组间半数遗精年龄的差异。结果 2019年宁夏回族自治区11~18岁男生超重和肥胖率分别为15.5%和8.8%，城市男生超重肥胖检出率分别为17.8%和10.5%，乡村男生分别为12.9%和6.9%。11~18岁城市男生半数遗精年龄为14.94岁，乡村男生半数遗精年龄为15.33岁(P < 0.01)。根据营养状况分组后，消瘦组、正常体重组、超重组和肥胖组男生半数遗精年龄依次为15.61，15.10，15.05，15.05岁。结论宁夏地区男生营养状况与首次遗精年龄无关，但营养状况与青春期发育的关系仍需进一步探索。

Abstract: Objective To explore the correlation between obesity and first ejaculation in boys aged 11-18 years old in Ningxia in 2019, and to provide the theoretical reference for puberty development among obese boys. Methods Using the method of stratified random cluster sampling, 5 240 boys aged 11- 18 were selected from Yinchuan, Zhongwei, Wuzhong and Guyuan in Ningxia Hui Autonomous Region. Height, weight, and first ejaculation were obtained.Body mass index (BMI) was calculated to determine nutritional status, and the χ² test was used to compare the differences between groups of nutritional status; the probability unit regression method was used to calculater the soth percentile age at ejaculation, and the U test was applied to compare the differences in age at ejaculation between groups. Results The rates of overweight and obesity among boys aged 11 to 18 years in Ningxia Hui Autonomous Region in 2019 were 15.5% and 8.8%. The detection rate of overweight and obesity among urban boys was 17.8% and 10.5% and the detection rate of overweight and obesity among rural boys was 12.9% and 6.9%, respectively. The 50 th percentile age at half ejaculation among urban boys aged 11 to 18 years was 14.94 years; the 50 th percentile age at ejaculation among rural boys was 15.33 years(P < 0.01). The 50 th percentile age at ejaculation was 15.61, 15.10, 15.05 and 15.05 years for boys in the wasted, normal weight, overweight and obese groups, respectively. Conclusion Nutritional status was not associated with age at first ejaculation in the present study, but warrants farther investigation.
