Abstract
Background
This study was done to determine whether the Osteoporosis Self-assessment Tool (OST) can predict central bone mineral density in Korean men above 50 years, as defi ned by dual energy X-ray absorptionmetry (DXA). Methods: We applied the OST index to Korean men aged over 50 in Health Promotion Center of Konkuk University Hospital from September 2005 to September 2008. The calculated OST risk index was based on weight and age, truncated to an integer. Results: The study population was 276 men. The mean age, height and weight of the men were 59.7 ± 6.69 years, 167.6 ± 6.14 cm and 67.5 ± 8.93 kg respectively. By DXA, 4.7% of the men had a T score of -2.5 or less, and 46.4% had a T score of -2 or less at the spine, total hip, or femoral neck. The OST index ranged from -4 to 7. Using a cutoff score of 0, we predicted osteoporosis with a sensitivity of 85% and a specifi city of 62%. The receiver operating characteristic curve showed an area under the curve of 0.77. When the subjects were analyzed by age and smoking status, the predictive value of the OST was maintained. Conclusion: The OST is a simple and useful method to predict osteoporosis in Korean men.
