摘　　要：【目的】了解昆明地区青少年骨量水平及影响因素。【方法】对昆明市某中学55名12～14岁青少年先行问卷调查再利用双能X线骨密度测定仪测量腰椎及髋部骨密度（bone mineral density，BMD）。【结果】女生腰椎、股骨颈、大转子骨密度明显高于男生；体重与BMD相关，体重越重BMD越高，但身高与BMD无明显相关关系；月经初潮年龄早的女生骨密度较高；喜欢运动的学生骨密度与不喜欢运动者差异有显著性；每日坚持喝牛奶的学生骨密度显著高于不喝牛奶的学生。【结论】影响昆明市青少年骨量水平的重要因素是：喝牛奶、运动、性别和体重。[Objective] To investigate the level of adolescent bone mass and the correlated influence factors in Kunming city. [Methods] Bone mineral density（BMD）of lumbar and proximal femur of 55 adolescent, aged 12 to 14, was measured with Dual energy X-ray absorptiometry（DEXA）in middle school of Kunming city, and a questionnaire was administered to all subjects before examining. [Results] The level of BMD in lumbar and femur neck and femur GT of girls were significant higher than those of boys. There was a positively correlation between BMD and weight, but BMD was not correlated with height. Menarche at earlier age was associated with a higher BMD （P〈0.05）. Compared with juvenile who did not like outdoor exercise, those like outdoor exercise revealed higher BMD levels. The BMD of adolescent who drink milk every day were greater than that of adolescent without milk intake. [Conclusion] Milk intake,outdoor exercise,sex and weight are important influencing factors of adolescents＇ BMD in Kunming city.
