摘要: 【目的】 了解上海市6~19岁中小学男生隐匿阴茎的现患率,并分析其与多种肥胖相关身体形态指标的关联。 【方法】 采用分层整群抽样方法,选取上海市小学1年级~高中3年级共1 787男生,通过外生殖器检查和身体测量,获取不同年龄、不同性发育阶段中小学男生的隐匿阴茎现患率,在为所有每1个病例按照学校和年级相同并且年龄相近原则选取4个对照的基础上,通过条件Logistic回归分析隐匿阴茎与肥胖相关多种身体形态指标的关联。 【结果】 隐匿阴茎的总检出率为2.5%,尤以11.0~15.9岁年龄组和性发育早期组的检出率较高。BMI、体重、腰围、臀围、腰臀比、肩胛下部皮褶厚度、肱三头肌部皮褶厚度对于隐匿阴茎的相对危险度分别为1.730、1.158、1.252、1.297、13.734、1.248、1.229,差异均有统计学意义。 【结论】 围青春期肥胖男性的隐匿阴茎问题应引起儿童保健工作者的高度注意,特别是青春发育初期;隐匿阴茎与肥胖相关的多种指标有关,尤其是中心性肥胖。
