不同月经状态女性青少年游泳运动员骨密度测定

目的探讨不同月经状态女青少年游泳运动员骨密度(bone mineral density,BMD)状况。方法选择2005年9月到2008年9月16-18岁、泳龄≥3年女性青少年游泳运动员220例,采用LunarDPX-NT双能X线吸收法(DXA)对运动员腰椎L1-L4骨密度进行测定。结果月经异常中骨密度的Z评分<-1者明显多于月经正常者(P<0.005)。结论月经异常者骨密度常降低,应减少活动量及改变饮食结构加以预防和纠正。

Objective To explore the different menstrual status of bone mineral density（bone mineral density,BMD）situation in adolescent girls swimmer.Methods Selected in September 2005 to September 2008,16-18 years old,swimming women age≥3 years 220 cases of young swimmers, using Lunar DPX-NT dual-energy X-ray absorptiometry（DXA）to measuring bone mineral density of athletes lumbar vertebrae L1-L4.Results The bone mineral density Z-score-1 of menstrual abnormalities are much more than normal menstruation persons（P0.005）.Conclusion The bone mineral density of abnormal menstruation persons often decrease,they should be reduced activity amount and changed dietary structure.
