The Osteoporosis Self-Assessment Tool for Asians (OSTA)
score has been developed to identify women at risk of
osteoporosis. It can be used as a screening tool for patients at risk who would benefit from bone mineral density measurement and treatment. It was developed based on data from eight countries including Malaysia. However, most subjects were of Chinese (59%). This study evaluated the performance of OSTA among 152 post-menopausal Malay
women. OSTA score calculation and DEXA scan were
performed. Our results showed that the OSTA score is a good
predictor of patients at risk of osteoporosis based on BMD
measurements at the proximal femur. Instrument sensitivity
was 87.5%, specificity was 95.8%, positive predictive value
(PPV) was 0.538, negative predictive value (NPV) was
0.993, and the area under the receiver operating
characteristic curve (ROC) was 0.895. We conclude that use
of the OSTA score in postmenopausal Malay women is
effective and has adequate sensitivity and specificity.
