Purpose: This cross-sectional study estimated three clinical tools including the Osteoporosis Self-Assessment Tool for Asians (OSTA), Body Mass Index (BMI), and Beijing Friendship Hospital Osteoporosis Self-assessment Tool for Elderly Male (BFH-OSTM) for identifying primary osteoporosis and found optimal cut-off values in an elderly Han Beijing male population. Materials and Methods: We conducted a cross-sectional study, enrolling 400 community-dwelling elderly Han Beijing males aged [greater than or equal to]50 from 8 medical institutions. Osteoporosis was diagnosed as a T-score of -2.5 standard deviations or lower than that of the average young adult in different diagnostic criteria [lumbar spine (L1-L4), femoral neck, total hip, WHO]. BFH-OSTM, OSTA, and BMI were assessed for predicting OP by receiver operating characteristic (ROC) curves. Sensitivity, specificity, and areas under the ROC curves (AUC) were determined. Ideal thresholds for the omission of screening BMD were proposed. Results: The prevalence of osteoporosis ranged from 9.25% to 19.0% according to different diagnostic criteria. The present study indicated the highest discriminating ability was BFH-OSTM in different criteria. The AUCs of OSTA and BMI were 0.748 and 0.770 in WHO criteria, which suggested limiting predictive value for identifying OP in elderly Beijing males. The AUC of BFH-OSTM to predict OP based on WHO criteria was 0.827, yielding a sensitivity of 65.8% and specificity of 82.7%, respectively. With a cost of missing 6.5% of osteoporosis patients, BFH-OSTM could reduce 73.5% of participants in screening BMD tests. Conclusion: BFH-OSTM may be a simple and effective tool for identifying OP in the elderly male population in Beijing to omit BMD screening reasonably.
