目的评估亚洲骨质疏松自我评估工具(Osteoporosis Self-assessment Tool for Asians,OSTA)指数对老年人骨质疏松的筛查价值。方法通过对上海市某社区签约建立健康档案的65岁及以上老年人进行问卷调查,测量身高、体重、骨密度等,并对调查结果采用性别、年龄分层分析处理,用ROC曲线评估OSTA指数预测骨质疏松的筛查价值。结果本次研究共调查5 832名65岁及以上老人,骨质疏松患病率30.37%。不同性别、年龄组的骨质疏松占比差异均有统计学意义(P<0.001)。不同性别、年龄组的OSTA高风险占比差异也均有统计学意义(P<0.001)。65~<70岁组和70~<80岁组的骨密度分级与OSTA风险分级的秩相关系数均>0(P<0.05)。以骨密度T值为金标准,OSTA指数评估骨质疏松的ROC曲线面积为0.460~0.570;女性65~<70岁的老年人OSTA筛查骨质疏松的灵敏度为0.902,特异度为0.093;男性65~<70岁的则分别是1.000和0.096;女性80岁及以上老年人OSTA筛查骨质疏松的灵敏度为0.125,而特异度为0.854。不同性别、年龄组和骨密度分级的OSTA指数值比较差异均有统计学意义(P<0.001)。结论 OSTA指数作为重要的骨质疏松筛查评估工具,在社区老年人群骨质疏松诊断中的筛查价值不高;在对老年人群采用OSTA指数评估骨质疏松筛查时,需要按年龄段和性别重新设置分级标准。
Objective To evaluate the screening value of the Osteoporosis Self-assessment Tool for Asians (OSTA) index on osteoporosis in the elderly. Methods A survey was conducted on the elderly aged over 65 years old and above who signed a health file in a community in Shanghai to survey the height, weight and bone mineral density. The survey results were stratified by sex and age. The ROC curve was used to evaluate the OSTA Predict the screening value of osteoporosis. Results A total of 5 832 elderly people aged 65 and above were surveyed in this study. The prevalence of osteoporosis was 30.37%. The differences of osteoporosis in different genders and age groups were statistically significant (P <0.001). The proportions of high-risk OSTA in different genders and age groups were also statistically significant (P <0.001). The rank correlations between BMD score and OSTA risk grade in 65 ~ <70 years old group and 70 ~ <80 years old group were both> 0 (P <0.05). The bone mineral density T value as the gold standard, OSTA index assessment of osteoporosis ROC curve area of 0.460 ~ 0.570; female 65 ~ <70 years old OSTA screening for osteoporosis sensitivity was 0.902, specificity was 0.093; male The odds ratios for screening for osteoporosis were 0.125 and 0.854 for OSTA in women aged 80 years and older, respectively, between 65 and 70 years old. The differences of OSTA index in different gender, age group and bone mineral density grade were statistically significant (P <0.001). Conclusion The OSTA index is an important screening tool for osteoporosis screening in the elderly community population osteoporosis screening value is not high; in the elderly population using OSTA index to assess osteoporosis screening, you need to age and Gender reset grading standards.
