Objective To evaluate the clinical value of osteoporosis screening tool Chinese( OSTC) in postmenopausal women in mainland China. Methods A total of 292 over 50 years old women were recruited from November 2013 to March 2014. Bone mineral density of the lumbar spine and the left femoral neck was examined using DXA. OSTC risk indexes of each subject were calculated based on their weight and age,and were then compared. Re sults The bone mineral density of the lumbar spine and the left femoral neck was positively correlated with OSTC indexes( r = 0. 430,r = 0. 623,P < 0. 001). According to the two risk levels,OSTC indexes could diagnose osteoporosis with the sensitivity of 92. 7% and with the specificity of 37. 1%. The area under ROC curve was 0. 760,and the 95% confidence interval was from 0. 697 to 0. 823. Conclusion OSTC index is positively correlated with bone mineral density,with high sensitivity. It can be used as an early screening tool for postmenopausal osteoporosis and has a high clinical application value. [ABSTRACT FROM AUTHOR]
