OBJECTIVE: To determine whether the Osteoporosis Self-assessment Tool (OST) can predict central bone mineral density in men, as defined by dual energy x-ray absorptiometry (DXA). PATIENTS AND METHODS: We applied the OST index to men in pulmonary (evaluated January-May 2001) and rheumatology (evaluated November 2001-March 2002) clinics at a veterans hospital. The calculated OST risk index is based on weight and age. RESULTS: In 181 men, we arbitrarily defined osteoporosis as a DXA T score of -25 or less in the spine, total hip, or femoral neck. The mean age and weight of the men were 64.3 years and 91.2 kg; 15.6% had osteoporosis by DXA. The OST index ranged from -5 to 19, from which we categorized risk as follows: low, 4 or greater; moderate,-1 to 3; and high, -2 or less. Only 2.0% of men with a low-risk OST index had osteoporosis, whereas 27.0% with a moderate risk and 72.7% with a high risk had osteoporosis. Using an OST cutoff score of 3, we predicted osteoporosis with a sensitivity of 93% and a specificity of 66%. When patients were studied by age in decades, race, or current glucocorticoid use, the predictive value of the OST was maintained. CONCLUSION: The OST is an easy method to predict osteoporosis by DXA.
