年龄、身高、体重、体重指数对福州地区中老年男性骨密度的影响

摘要

Objective To investigate and analyze the effects of age, height, weight, and body mass index ( BMI ) on bone mineral density ( BMD ) of the lumbar vertebrae, the femur neck, Wards region, and the trochanter in middle-aged males in Fuzhou. Methods A total of 338 middle-aged men were selected randomly. BMD of the lumbar vertebrae, the femur neck, Wards region, and the trochanter were measured using dual energy X-ray absorptiometry. Age was recorded. Height, weight was measured. BMI was calculated. A SPSS 19. 0 software was applied for statistical analysis, including Pearson correlation analysis and one-way ANOVA for age, height, weight, BMI and BMD among groups. Results Age was significantly correlated with BMD of the femur neck and Wards region in middle-aged males. BMD in the old group (≥ 75 years ) was significantly lower than that in the young group ( < 60 years ). Height was significantly correlated with BMD of the lumbar vertebrae, the femur neck and the trochanter in middle-aged males. People with the height over 170 cm had higher BMD. Weight and BMI of middle-aged males were significantly correlated with BMDs of the lumbar vertebrae and the trochanter. BMD in low weight group ( < 60kg) and low BMI group ( BMI < 19 ) was lower than that in other groups, and the difference was significant. Conclusion Age, height, weight and BMI are important factors that influence BMD of middle-aged males in Fuzhou. BMD of elderly males with low BMI is lower than that of others. So they should receive BMD detection timely for an early diagnosis in order to prevent and treat osteoporosis.%目的 调查分析年龄、身高、体重及体重指数(Body Mass Index,BMI)对福州地区中老年男性人群腰椎、股骨颈、ward's区和大转子骨密度的影响.方法 在福州地区进行随机抽样338例中老年男性,采用双能X线骨密度仪检测腰椎、股骨颈、ward's区和大转子骨密度,记录年龄,测量身高、体重,计算出体重指数.应用SPSS19.0统计软件进行年龄、身高、体重、BMI与各部位骨密度Pearson相关分析及组间单因素方差分析(ANOVA).结果 中老年男性的年龄与股骨颈和ward's区骨密度相关十分显著,高龄组(≥75岁)的骨密度明显低于低龄组(＜60岁);中老年男性的身高与腰椎、股骨颈、和大转子骨密度显著相关,身高170 cm以上组人群具有较高骨密度;中老年男性的体重、BMI与腰椎、大转子骨密度显著相关,低体重组(＜60 kg)及低BMI组(BMI＜19)骨密度明显更低,差异具有显著性意义.结论 年龄、身高、体重和体重指数是影响福州地区中老年男性骨密度的重要因素,低体重指数的老年男性骨密度较低,应及时检测骨密度,以早期诊断和防治骨质疏松症.
