【摘要】：目的调查分析兰州市汉族成人骨强度指数特点及其与体成分之间的关系,为该地区骨质疏松的预防和干预提供参考依据。方法采用超声骨密度仪及生物电阻抗分析仪测量2291例(男1021例,女1270例)兰州市汉族成人右足跟骨骨强度指数及体成分等相关指标,采用多元逐步回归法分析骨强度指数与体成分各指标之间的关系。结果兰州市汉族成人骨强度指数随年龄增长而持续降低,峰值骨量出现在20~30岁。其中男性20~30岁和50~60岁两个年龄段骨强度指数下降较快,而女性50岁后骨强度指数迅速下降;兰州市汉族男性各年龄组骨强度指数均高于同龄组女性。与采用相同方法测量其他民族、地区人群有关指标进行比较得知,兰州市汉族成人骨强度指数值和兰州汉族女性峰值骨量值均较低。多元线性回归分析显示,肌肉含量、皮下脂肪、身体质量指数与骨强度指数呈正相关,内脏脂肪与骨强度指数呈反比。结论兰州市汉族成人骨强度指数和兰州市汉族女性峰值骨量均处于较低水平,且峰值骨量出现的年龄较早,50岁以后女性是骨质疏松的危险人群;肌肉量、皮下脂肪量以及BMI是骨质疏松发病的保护性因素,而内脏脂肪量是骨质疏松发病的危险因素。
[Abstract]:Objective to investigate and analyze the characteristics of bone strength index and its relationship with body composition in Lanzhou Han adults, and to provide reference for the prevention and intervention of osteoporosis in this area. Methods the bone strength index and body composition of right heel of 2291 Han adults (1021 males and 1270 females) were measured by ultrasonic absorptimeter and bioelectrical impedance analyzer. The relationship between bone strength index and body composition was analyzed by multivariate stepwise regression method. Results the bone strength index of Han adults in Lanzhou continued to decrease with the increase of age, and the peak bone mass appeared in 20 卤30 years old. The bone strength index of male 20 age group and 50 age group decreased rapidly, while that of female group decreased rapidly after 50 years old, and the bone strength index of Han men in Lanzhou was higher than that of women of the same age group. Compared with the relevant indexes of other ethnic and regional populations measured by the same method, the bone strength index of Han adults in Lanzhou and the peak bone mass of Lanzhou Han women were lower. Multiple linear regression analysis showed that muscle content, subcutaneous fat and body mass index were positively correlated with bone strength index, while visceral fat was inversely proportional to bone strength index. Conclusion the bone strength index of Han adults in Lanzhou and the peak bone mass of Han women in Lanzhou are at a low level, and the age of peak bone mass is earlier. After 50 years old, women are at risk for osteoporosis, muscle mass, subcutaneous fat content and BMI are the protective factors of osteoporosis, and visceral fat content is the risk factor of osteoporosis.
