摘要：

目的 探讨回族大学生骨密度和体成分变化特点及相互关系。方法 采用横断面整群分层随机抽样的方法选取390名20～22岁回族大学生（其中男生195名，女生195名）为研究对象，人体体成分分析仪测定体成分，超声骨密度测定仪测定骨密度，并进行骨质 T-score综合评价。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项骨密度指标均高于回族女生，回族女生骨质正常率高于回族男生；回族男生体质指数（BMI）、瘦体重、肌肉量、矿物质、身体水分、蛋白质、腰臀围比、基础代谢8项体成分指标总体及各年龄组均高于回族女生，而脂肪量、体脂肪率、水肿指数３项体成分指标总体及各年龄组均低于女生；除回族女生BMI与T值、QUI之间存在正相关性，其他各项体成分指标与骨密度指标之间均无相关性。 结论 回族大学生骨密度和体成分状况较好。体成分与骨密度的相互关系不明显。

Abstract:

Objective To analyze the characteristics of bone density and body composition changes in Hui university students and to provide some theoretical suggestions for the improvement of Hui university students’ physical health. Methods The sampling methods of cross-sectional stratified random were used to select 390 samples, aged from 20 to 22, in Hui university students (195 males, 195 females). Body composition was measured by the human body composition analyzer. Bone density was measured by bone mineral density ultrasound bone density, and comprehensive analysis of bone T-score was evaluated. Results The bone density indexes of broadband ultrasonic frequency attenuation (BUA), speed of sound (SOS), quantitative ultrasound index (QUI) and bone mineral density (BMD) in Hui male students were higher than in Hui female students. Normal rates of bone of Hui female students were higher than that of Hui male students.BMI, lean body mass, muscle mass, minerals, body water, protein, waist-hip ratio and basal metabolic indexes of Hui male students were higher than Hui female students in overall and every age-group body composition. However, the indexes of the amount of fat, body fat percentage and oedema index in Hui male students were lower than that of Hui female students in overall and every age-group body composition. Indexes of BMI and T values and QUI were positive correlation for Hui female students, and there was no correlation between indexes of body composition and bone density. Conclusion The condition of body composition and bone density is well in Hui male and female students. The correlation between indexes of body composition and bone density is not clear.
