不同人口学特征老年人的骨密度评测结果

Results of bone mineral density testing among elderly people with different demographic characteristics

目的分析不同人口学特征老年人的骨密度评测结果,为老年人骨质疏松的早期预防提供依据。方法对2012年9月—2013年5月武警后勤学院附属医院老年门诊就诊的728名60岁及以上老年人群,进行骨密度测定和一般人口学调查。结果老年人腰椎、股骨颈、Ward三角3个部位骨密度及T值评测结果分别为（0.90±0.44）、（0.67±0.15）、（0.48±0.17）和（-1.80±1.79）分,其中Ward三角骨密度值最低。多因素分析显示,影响腰椎评测结果的有性别和运动;影响股骨颈评测结果的有性别、年龄、婚姻、职业和运动,影响Ward三角、T值评测结果的有性别、年龄、婚姻和运动;男性〉女性,运动量较多〉中等〉少者,非劳力〉劳力者,60岁~〉65岁~〉70岁~〉75岁~,老伴健在〉丧偶者（P〈0.05）,其中性别和运动是影响老年人骨密度及T值评测结果的共同因素。结论不同人口特征老年人的骨密度评测结果不同,高龄、女性、丧偶、运动少、劳力型职业的老年人骨密度低,为骨质疏松的高风险人群,应重点关注该群体,进行早期预防。

[Objective]To analyze the results of bone mineral density （BMD） testing among elderly people with different demographic characteristics, provide the basis for early prevention of osteoporosis in the elderly people.[Methods]728 elderly people over 60 years old, who have visited the Geriatrics Clinic of Hospital Affiliated to the Logistics College of the Armed Police from September 2012 to May 2013, were enrolled in this study, to receive the bone densitometry and general demographic survey.[ResultslThe BMD level of lumbar spine, femoral neck, Ward triangle and T-score was respectively （0.90±0.44）, （0.67± 0.15 ）, （0.48±0.17） and（-1.80±1.79）, and the B MD of Ward triangle was the lowest. Multivariate analysis showed that the factors affecting the lumbar spine evaluation results were gender and exercise, the factors influencing the femoral neck evaluation results were gender, age, marital status, occupation and exercise, and the influencing factors of the factors affecting the Ward triangle evaluation results and T-score were gender, age, marital status and exercise. The results were as follows： Male〉 female, people with more exercise〉medium exercise〉less exercise, non-laborer〉laborer, 60-65 year-old group〉65-70 year-old group〉70-75 yearold group〉 over 75 year-old group, people with life partner〉widowed people （P〉0.05）. Gender and exercise were common factors affecting BMD and T-score evaluation results in elderly people. [Conclusion]The elderly people with different demographic characteristics have different BMD results. The people who are old, female, widowed, with less exercise and engaged in labor occupation show the lower BMD level, and they are the high-risk population of osteoporosis. It is necessary to pay attention to this population, and carry out the early prevention.
