目的通过查体和调查问卷分析蒙古族大学生骨质状况及其相关影响因素。方法使用GE EXPRESSⅡ超声骨密度测量仪对919名20～23岁蒙古族大学生（其中男生403名,女生516名）进行骨强度指数测量,采用问卷调查其生活方式,并通过计算T值评估其骨质状况。结果蒙古族大学生骨强度指数以及骨质正常率均表现为随年龄增加先升高后降低的趋势。蒙古族男生骨强度指数高于女生,但是蒙古族女生骨质正常率高于男生,其中各年龄组以及城镇、乡村各组间,蒙古族女生均未发现骨质疏松。Logistic回归分析显示,吸烟情况、锻炼情况为蒙古族大学生骨质异常的主要影响因素。与其他民族、地区的大学生比较发现,蒙古族男生骨强度指数较高,而蒙古族女生骨强度指数较低,且蒙古族男女大学生骨质状况差异无统计学意义。结论蒙古族大学生骨质状况良好,加强运动,减少吸烟可改善骨质状况。

英文摘要：

Objective To analyze the bone condition and correlated influencing factors in Mongolian undergraduate students by physical examination and questionnaire. Methods The bone strength index was tested by GE EXPRESS Ⅱ ultrasonic bone mineral density instrument,life-style evaluation was investigated by questionnaire, and comprehensive analysis of bone T value was evaluated in 919 Mongolian undergraduate students（ 403 males and 516females）,aged from 20 to 23 years. Results The prevalence rate of bone strength index and normal values of bone were increased firstly and decreased subsequently with age. The bone strength index was higher in Mongolian male students than Mongolian female students,but the normal values of bone was higher in Mongolian female students than Mongolian male students. There was no osteoporosis patient in Mongolian female students,and no difference was detected between agegroups,and urban and rural groups. Smoking condition and exercise situation were the main influence factors for bone abnormal by logistic regression analysis. The bone strength index in Mongolian male students was higher compared with other nations and areas. However,the bone strength index was lower in Mongolian female students. There was no difference between Mongolian undergraduate students and others in bone condition. Conclusion The sclerotin situation is normal in Mongolian undergraduate students. Increasing exercises and reducing smoking may improve bone condition.
