Objective To establish an osteoporosis screening tool for Chinese40-years-old or above women. Methods The T-score was calculated based on the mean bone mineral density(BMD) of 20-39 years women. Considering the result of dualenergy X-ray absorptiometry(DXA) as the golden criteria, the Bayes discriminant analysis was employed to explore the function. Results The formula of the screening tool for Chinese 40-years-old or above women as following:osteoporosis screenig tool for Chinese(OSTC):Weight-2×age+50. OSTC≤0was classified into high risk, OSTC gt;0 was low risk. The hit rate of OSTC was 75.78%.The sensitivity is 76.8%. The specificity is 75.1%, Kappa value was 0.51(P=0.000).That means the consistency of diagnosis result between OSTC and DXA was relatively good. Conclusion OSTC is a simple tool. Just based on age and weight, it can evaluate the osteoporosis risk of Chinese 40-years-old or above women. But the effect of OSTC has not been proved by other datasetand should be tested further.
