【摘要】 了解机关工作人员骨质健康状况,探寻变化规律及其影响因素。应用定量超声(QUS)技术,对厦门市852名机关工作人员进行跟骨密度测量和分析,其中男性498人,女性354人,年龄23—60岁,各以每5岁为一年龄组。结果:青年男性(21—30岁)骨硬度指数(SI)明显高于同龄组的女性(P<0.05),男性SI的峰值出现早于女性;SI随年龄增加呈逐渐下降趋势,男性51—55岁、56—60岁分别降到同性别骨峰值的84.9%和83.3%;女性51—55岁降为同性别骨峰值的91.8%;男女SI均与年龄呈负相关,与身高、体重呈正相关,而与BMI无相关性;男女骨质正常者所占比例随年龄增长而逐渐降低,骨质疏松患病率随年龄增长而逐渐增高。结论:厦门市机关工作人员骨密度总体表现满意,男性高于女性;身高、体重、年龄是影响骨密度的重要因素;合理的体育锻炼可以增加骨密度,预防骨质疏松症。更多还原

【Abstract】 To understnd the bone health and explore the changing rule and influencing factors,this paper measured and analyzed calcaneus bone density of 852 Provincial Government Employees in Xiamen by quantitative ultrasound. The result showed that the stiffness index( SI) of male youth is obviously better than that of female youth( P < 0. 05),the peak value of SI in male presented before female,the SI showed a downtrend with increasing age. The SI were negatively associated with age and positively associated with height and weight,but were no correlation with BMI. The prevalence of osteoporosis gradually increases with age. The conclusion is the bone density of the Provincial Government Employees in Xiamen is satisfactory,male is better than female,height,weight and age are the important influencing factors for BMD,physical training can improve bone density and prevent osteoporosis.更多还原
