大连市沙河口区女生青春期发育调查

Investigation of the Puberty Growth of Female Students in Shahekou District of Dalian

目的了解区内女学生青春期发育状况，为做好女生的卫生保健工作提供科学依据。方法采用概率单位回归法，求出女生半数月经初潮年龄，同时取10～13岁来潮女生182名，选出生年月日与来潮女生相差不超1个月的未来潮女生配对，分别统计各年龄组的身长、体重、胸围及视力、龋齿患病情况。结果9～18岁女生半数月经初潮年龄1991年为12．637岁，2002年为12．326岁。来潮女生的身高、体重、胸围均值均高于未来潮女生，二者差异有统计学意义。龋齿患病率，来潮女生较未来潮女生低。结论近12年来女生月经初潮年龄有提前趋势，但速度减慢。来潮女生的形态发育好于未来潮女生，口腔卫生状况的好坏是关系到女生青春发育的至关重要问题。
