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 bone mineral density (BMD) of elderly with different demographic characteristics and provide evidence for early prevention of osteoporosis in the elderly. Methods A total of 728 elderly people aged 60 and over in the Geriatric Clinic of the Armed Police Hospital Affiliated Hospital from September 2012 to May 2013 were surveyed for bone mineral density (BMD) and general population survey. Results The bone mineral density and T value of the lumbar spine, femoral neck and Ward triangle were (0.90 ± 0.44), (0.67 ± 0.15), (0.48 ± 0.17) and (-1.80 ± 1.79) points respectively in the elderly, of which Ward Triangular bone mineral density is the lowest. Multivariate analysis showed gender and age, marital status, occupation and sports affecting the results of the femoral neck test, sex, age, marriage and exercise affecting the Ward trigonometry and T value. Male> Female, Excessive amount of exercise> Moderate> Less, Non-labor> Laborer, 60-65 years old-> 70-75 years old, His wife was> widowed (P <0.05) Is affecting the elderly bone mineral density and T value of the evaluation of common factors. Conclusion The BMD of elderly with different demographic characteristics is different. The elderly, women, widowed, less exercise and labor-intensive elderly have lower bone mineral density and are the high-risk groups of osteoporosis. Therefore, we should pay more attention to this group and carry out early prevention .
