【摘要】：目的分析老年男性骨密度(bone mineral density,BMD)与身体成分的关系。方法记录166名80~94岁老年男性的年龄、身高、体重、BMI,检测L1-4、左侧股骨颈、Wards三角、大粗隆、左侧股骨上端的BMD及总肌肉含量(total lean mass,TLM)和总脂肪含量(total fat mass,TFM),根据BMD水平将受试者分为骨量正常组(n=50)、骨量低下组(n=91)和骨质疏松组(n=25)。结果 (1)骨量低下组及骨质疏松组的BMD均明显低于正常骨量组(P0.01),骨质疏松组又明显低于骨量低下组(P0.01);(2)骨质疏松组体重、TLM、TFM及BMI均明显低于正常骨量组(P0.01);(3)TLM与左侧股骨颈、Wards三角、左侧股骨上端的BMD相关系数分别为0.227、0.203及0.193(P0.05),TFM与腰椎1-4、左侧股骨颈、Wards三角、大粗隆、左侧股骨上端的BMD相关系数为0.269、0.222、0.206、0.246及0.242(P0.01)。结论大部分老年男性BMD与年龄呈显著负相关;与体重、BMI及TFM、TLM呈显著正相关,适当的运动和适度的肥胖,增强肌肉量和维持一定的脂肪量,保持健康的体重,可能有利于预防老年性骨质疏松症。
[Abstract]:Objective to analyze the relationship between bone mineral density (BMD) and body composition in elderly men. Methods the age, height and weight of 166 male patients aged 80 to 94 years were recorded. The BMD and total lean mass of the upper femur on the left side and the total fat mass TFM of the left femur were divided into two groups according to the BMD level: normal bone mass group, low bone mass group and osteoporosis group. Results the results showed that the patients had low bone mass and osteoporosis. The BMD of the osteoporosis group was significantly lower than that of the normal bone mass group (P 0.01) and the osteoporosis group was significantly lower than that of the low bone mass group (P 0.01). The TFM and BMI of the osteoporosis group were significantly lower than that of the normal bone mass group (P 0.01) and the left femoral neck titers triangle. The BMD correlation coefficients of the upper end of the left femur were 0.2270.203 and 0.1993 P0.05 respectively with lumbar vertebrae 1-4, the left femoral neck wards triangle, the great trochanter, the BMD correlation coefficient of the left upper end of the femur were 0.269 and 0.2220.2060.246 and 0.242P0.01.Conclusion most of the aged men have negative correlation between BMD and age. There was a significant positive correlation with BMI and TFM TLM. Proper exercise and moderate obesity, increasing muscle mass and maintaining a certain amount of fat, and maintaining healthy weight may be beneficial to the prevention of senile osteoporosis.
