目的确定几种常见生活因子对中老年男性骨密度(BMD)的影响,以便指导骨质疏松症的防治工作。方法对在武汉同济医院高干病房进行体检的286例50～79岁的汉族中老年男性采用问卷方法进行生活饮食习惯等情况调查;用双能量X线骨密度测量仪(DEXA)测定腰椎及股骨颈BMD值,并进行统计分析。结果(1)将平均每天摄钙量按从低至高分A、B、C3组,其中年龄在60～69岁的C组腰椎及股骨颈BMD明显高于A组(P<0.01),与B组比较其股骨颈BMD差异也有统计学意义(P<0.05);70～79岁年龄的C组腰椎及股骨颈BMD与A、B组比较均有很大差距,差异有统计学意义(P<0.05)。(2)不同的蛋白质摄入量及饮酒对骨密度的影响不明显。(3)吸烟对骨密度有较大影响,吸烟组股骨颈BMD低于非吸烟组(P<0.05)。(4)运动对骨密度有较大影响,运动组股骨颈BMD高于非运动组(P<0.05)。结论增加钙的摄入有助骨密度的提高;蛋白质的摄入情况以及饮酒对骨密度影响不大;吸烟促进骨密度的降低;运动有助于骨密度的提高。
Objective To determine the impact of several common life factors on bone mineral density (BMD) in middle-aged and elderly men in order to guide the prevention and treatment of osteoporosis. Methods A total of 286 Han Chinese middle-aged and elderly men and women aged 50-79 years who were physically examined in the high-altitude ward of Tongji Hospital of Wuhan City were surveyed by questionnaires for their daily living habits. The lumbar spine and femur were measured by dual-energy X-ray absorptiometry (DEXA) Neck BMD value, and statistical analysis. Results (1) According to the average daily intake of calcium, the BMD of lumbar spine and femoral neck in group C were significantly higher than those in group A (P <0.01), and those in group B There were also significant differences in BMD of femoral neck between the two groups (P <0.05). The BMD of lumbar spine and femoral neck in group C between 70-79 years old was significantly different from that in groups A and B (P < 0.05). (2) The effect of different protein intake and alcohol consumption on bone mineral density was not obvious. (3) Smoking had a significant effect on BMD. BMD of femoral neck in smoking group was lower than that in non-smoking group (P <0.05). (4) Exercise had a significant effect on BMD. The femoral neck BMD in exercise group was higher than that in non-exercise group (P <0.05). Conclusion Increasing calcium intake may promote the increase of bone mineral density. The intake of protein and drinking alcohol have little effect on the bone mineral density. Smoking promotes the decrease of bone mineral density. Exercise helps to improve the bone mineral density.
