【摘要】：目的探讨苏州市男性儿童青少年发育与超重肥胖的关系,为制定儿童青少年青春期预防保健措施提供参考。方法随机分层整群抽取苏州地区15所中小学的男生5 059名,根据中国学生超重、肥胖BMI筛查标准,将调查学生分为超重、肥胖、正常3组,调查青春期男生的首次遗精年龄,测量身高、体重,调查第二性征发育等级。结果苏州市中小学男生超重检出率为10.6%(538/5 059),肥胖检出率为5.1%(257/5 059),已发生首次遗精的占19.4%(963/5 059)。超重组、肥胖组男生首次遗精年龄晚于正常组,差异有统计学意义(P0.05)。BMI值与首次遗精年龄呈正相关(r=0.229,P0.01);11～15岁组男生BMI值与外生殖器发育程度、阴毛发育程度呈负相关(P值均0.01)。结论苏州市男性儿童青少年青春期发育与肥胖密切相关。
[Abstract]:Objective to explore the relationship between the development of male children and adolescents and overweight and obesity in Suzhou, and to provide reference for the development of adolescent health care. Methods Fifty nine male students from 15 primary and secondary schools in Suzhou were randomly selected by stratified cluster. According to the BMI screening criteria for overweight and obesity of Chinese students, the investigated students were divided into three groups: overweight, obesity and normal. The age of first spermatozoa of adolescent boys was investigated. Height and weight were measured and secondary sexual development grades were investigated. Results the prevalence rate of overweight and obesity was 10.6% (538 / 5059) and 5.1% (257 / 5059) in primary and middle school boys in Suzhou. The percentage of first spermatozoa was 19.4% (963 / 5059). The age of the first spermatozoa in the obese group was later than that in the normal group, and the difference was statistically significant (P0.05). There was a positive correlation between the). BMI value and the age of the first spermatozoa (r = 0.229, P0.01). There was a negative correlation between the BMI value and the development degree of external genitalia and pubic hair in 1115 year old male students (P < 0. 01). Conclusion the puberty development of male children and adolescents in Suzhou is closely related to obesity.
