【摘要】：目的探讨西藏藏族成人骨强度指数的变化特点,并分析骨量异常与体成分的相关性。方法抽取西藏藏族自治区日喀则市藏族成人560例,采用生物电阻抗分析仪及超声骨密度仪分别测量被研究者体成分各指标及右足跟骨骨强度指数、T值等,采用非条件Logistic回归法分析骨量异常与体成分间的关系。结果西藏藏族男女性成人骨强度指数均在18~30岁达到峰值,之后随年龄增长而下降;50岁以上男女性骨质疏松症检出率分别为7.6%及11.7%;Binary Logistic回归分析显示,年龄(B=0.046,OR=1.047,P0.01)、内脏脂肪量(B=0.452,OR=1.572,P0.05)是西藏藏族成人发生骨量异常的危险因素,而皮下脂肪含量(B=-0.181,OR=0.835,P0.01)及肌肉量(B=-0.055,OR=0.947,P0.05)是骨量异常的保护性因素,腰臀比与骨量异常无相关性。结论西藏藏族50岁以上人群骨质疏松症发病率相对国内其他报道的民族同龄人群较低;内脏脂肪量越高、皮下脂肪量及肌肉量越低者,发生骨量下降及骨质疏松症的危险性越高。
[Abstract]:Objective to investigate the characteristics of bone strength index in Tibetan adults in Tibet, and to analyze the correlation between bone mass abnormality and body composition. Methods 560 Tibetan adults from Xigaze City, Tibet Autonomous region, were selected. Bioelectrical impedance analyzer and ultrasonic absorptiometry were used to measure the indexes of body composition and calcaneal bone strength index of right foot. The relationship between abnormal bone mass and body composition was analyzed by non-conditional Logistic regression method. Results the bone strength index of Tibetan men and women reached its peak at the age of 1830. The prevalence rate of osteoporosis in men and women over 50 years of age was 7.6% and 11.7B Logistic regression analysis showed that the age group was 0.046 Osteoporosis 1.047 and the visceral fat content was 0.452OR1.572P0.05) as a risk factor for abnormal bone mass in Tibetan adults in Tibet. But the content of subcutaneous fat was 0. 835 (P 0. 01) and muscle volume was 0. 947 (P 0. 05). The ratio of waist to hip was not correlated with the abnormality of bone mass. Conclusion the incidence of osteoporosis in Tibetan people over 50 years old is lower than that in other ethnic groups reported in China. The higher the visceral fat, the lower the subcutaneous fat and muscle mass, the higher the risk of osteopenia and osteoporosis.
