回族大学生骨密度状况及其相关影响因素分析

Bone mineral density condition in Hui undergraduate students and analysis on correlative influence factors

目的:了解回族大学生骨密度变化特点及相互关系,为提高回族大学生体质健康提供理论依据.方法:对390名20～22岁回族大学生(其中男生195名,女生195名)进行骨密度测试及问卷调查.结果:回族男生宽带超声频率衰减(BUA)、超声声速(SOS)、定量超声指数(QUI)和骨矿物质密度(BMD)4项指标均高于回族女生,回族乡村女生BUA、SOS、QUI和BMD 4项指标高于回族城镇女生.回族女生各年龄组间骨质有差异,且回族女生骨质正常率高于回族男生,回族乡村女生骨质正常率高于回族城镇女生.锻炼、吸烟、性别均为骨质异常的影响因素.结论:回族大学生骨密度状况较好.加强运动,减少吸烟可促进骨密度提高.

Objective:To analyze the characteristics and correlative influence factors of bone mineral density of Hui undergraduate students and to provide some theoretical suggestions for the improvement of Hui undergraduate students’ physical health.Methods:390 Hui undergraduate students(195 males,195 females),aged from 20 years to 22 years were selected for bone mineral density test and questionaire.Results:In Hui male students,the indexes of broadband ultrasonic frequency attenuation(BUA),speed of sound(SOS),quantitative ultrasound index(QUI) and bone mineral density(BMD)were higher than those in Hui female students.In Hui female students in rural,the indexes of BUA,SOS,QUI and BMD were higher than those in Hui female students in urban.In every age-group,the sclerotin of Hui females was different.Normal rates of the bone of Hui female students were higher than those of Hui male students,and normal rates of bone of Hui female students in rural areas were higher than those in urban areas.Doing exercises,smoking and sex differences were influence factors for bone abnormalities.Conclusion:BMD of Hui undergraduate students has good condition.Increasing exercises and reducing smoking may promote bone density.
