RESUMO
Objective To evaluate the application of osteoporosis self-assessment tool for Asians (OSTA) in screening of osteoporosis for postmenopausal women in community.Methods Total 793 postmenopausal women were included.OSTA were calculated and bone mineral density (BMD)was measured by dual energy X-ray absorptiometry (DXA).The correlation of OSTA index with DXA results was analyzed.Results The prevalence of osteoporosis and osteopenia was 18.3％ (145/793) and 47.7％(378/793) respectively,the remaining 270 women had normal bone mass (34.0％).According to OSTA index the rate of low-risk,medium-risk,high-risk osteoporosis groups were 61.9％ (491/793),29.5％(234/793) and 8.6％ (68/793),respectively.The BMD measured by DXA was positively correlated with OSTA index(r =0.559,P =0.000).The area under receiver operating characteristic curve (ROC) of OSTA for diagnosing osteoporosis was 0.736.Taking-1 as cut off value,the sensitivity and specificity of OSTA in diagnosis of osteoporosis was 73.1％ (106/145) and 69.8％ (452/648),respectively.Conclusion OSTA can be used as an effective index for screening of osteoporosis in postmenopausal women in community.
