摘　　要：目的分析中国2010—2019年11~18岁汉族男生首次遗精年龄长期趋势及其与营养状况的关联。方法利用2010、2014和2019年全国学生体质与健康调研数据,采用询问法收集研究对象年龄、居住地和首次遗精情况,并测量其身高和体重,共纳入遗精情况、身高、体重资料完整的11~18岁汉族男生184633名。采用概率回归法计算各地区首次遗精中位年龄(95%CI),比较不同特征对象首次遗精年龄变化趋势,采用多因素logistics回归模型分析11~18岁汉族男生首次遗精与营养状况的关联。结果2019年中国11~18岁汉族男生首次遗精中位年龄(95%CI)为13.85(13.45~14.22)岁,比2010年提前0.18岁;城市和乡村男生首次遗精中位年龄分别为13.89和13.81岁,与2010年相比,城乡男生首次遗精年龄分别提前了0.08和0.27岁。多因素logistics回归模型分析结果显示,调整年龄、省份与城乡等因素后,正常体重男生为参照,首次遗精与消瘦呈负向关联,与超重、肥胖呈正向关联,OR(95%CI)值分别为0.73(0.67~0.80)、1.09(1.02~1.17)和1.09(1.01~1.18)。结论中国汉族男生首次遗精年龄呈提前趋势且与营养状况存在关联。Objective To analyze the long-term trend of the age of spermarche among Chinese Han boys aged 11 to 18 years from 2010 to 2019 and its association with nutritional status.Methods The data from Chinese National Surveys on Students′Constitution and Health in 2010,2014 and 2019 were used.The age,residence and spermarche of the participants were collected by questionnaire,and their height and weight were measured.A total of 184633 Han boys aged 11‒18 years with complete data on spermarche,height,and weight were included in this study.The probability regression method was used to calculate the median age(95%CI)at spermarche in different areas,and the trend of age at spermarche in different groups was compared.The multivariate logistic regression model was used to analyze the association between nutritional status and spermarche of Chinese Han boys aged 11‒18 years.Results The median age of spermarche(95%CI)was 13.85(13.45-14.22)years old among Chinese Han boys aged 11‒18 years in 2019,with 0.18 years earlier than that in 2010.The median age at spermarche in urban and rural boys was 13.89 and 13.81 years,respectively.Compared with that in 2010,the age at spermarche in urban and rural boys was 0.08 and 0.27 years earlier,respectively.After adjusting for age,province and urban/rural areas,compared with normal weight,spermarche was negatively associated with wasting and positively associated with overweight and obesity,with OR(95%CI)about 0.73(0.67-0.80),1.09(1.02-1.17)and 1.09(1.01-1.18),respectively.Conclusion The age of spermarche generally shows an advanced trend among Chinese Han boys and is associated with nutritional status.
