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(P<0.05)。BMI值与首次遗精年龄呈正相关(r=0.229,P<0.01);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。Objective To examine the relationship of pubertal development with body fatness in male children and adoles- cents of Suzhou.
