objective to determine the menarche age among female students and the relation between body fat and menarche in anhui province to provide theoretical basis for adopting intervention measure and carrying out health education.methods probability unit regression were used to calculate mmas in 3 000 girls aged 9～18 years old,who were selected from 3 areas in 2005.results mmas were 12.76 and 13.11 years old for urban and rural girls respectively.the youngest age was 10.the menarche age was significantly,related with bmi sebum thickness of abdomen,sebum thickness of shoulder blade and the upper arm.conclusion there was significant relationship between menarche age and body fat.menarche age showed an ahead trend in han national students in anhui province.sex eduction should be conducted in advance,and it was important to strengthen sex education in adolescent.

目的 了解安徽省女生月经初潮及初潮前后体脂变化情况，为采取干预措施和健康教育提供理论依据。方法按照2005年全国学生体质调研要求，采用分层整群抽样方法，对安徽省南、中、北3个地区城乡9～18岁中小学女生3000人进行调查，并测量体质指数、腹部皮脂厚度、上臂皮脂厚度和肩胛下皮脂厚度4项指标。结果城市女生半数月经初潮平均年龄为12.76岁，农村女生13.11岁，城乡最小月经初潮年龄均为10岁。体质指数、腹部皮脂厚度、上臂皮脂厚度和肩胛下皮脂厚度4项指标均值来潮组均大于未来潮组，差异有统计学意义，p.01。结论月经初潮年龄与体脂因素关系密切；安徽省汉族学生月经初潮年龄呈现提前趋势，性教育应提前，加强青春期性教育尤为重要。
