摘要
【目的】了解九江市儿童性早熟的发病率及发病原因,为该病预防提供理论依据。【方法】采取分层整群抽样方法,以九江市三个区4所小学和3所幼儿园共3 312名3～12岁儿童为调查对象,进行乳房、阴毛、睾丸等分期评定,通过发放家长调查问卷了解受调查者月经初潮和遗精、饮食睡眠生活习惯、特殊爱好以及父母亲青春期发育情况。【结果】九江市城区儿童性早熟检出率为0.68%,女童检出率(1.25%)高于男童(0.11%)差异有统计学意义(χ2=16.119,P=0.000)。乳房开始发育年龄平均为(10.26±2.34)岁,城区女童[(9.91±1.85)岁]早于郊区女童[(11.29±1.38)岁],差异有统计学意义(P=0.000)。阴毛发育年龄平均为(11.67±0.84)岁,城区女童[(11.68±0.85)岁]和郊区女童[(11.63±0.86)岁],差异无统计学意义。在常食动物性食物、营养滋补品、饮料,缺乏体育锻炼、不良生活习惯、父母缺乏育儿知识、以及遗传因素等在儿童性早熟组和正常组中差异有统计学意义。【结论】经常进食动物性食物、营养滋补品、饮料,缺乏体育锻炼、不良生活习惯、父母缺乏育儿知识、以及遗传因素在性早熟发病中起促进作用。
