【摘要】Objective To compare the efficiency of osteoporosis self-assessment tool for Asians (OSTA) and body mass index (BMI) in identifying osteoporosis.Methods Totally 5745 cases (2094 male and 3651 female) over 50 years old were included.Bone mineral density (BMD) was measured using dual energy X-ray absorptiometry (DXA).OSTA index and BMI were calculated,and their predictive values of osteoporosis were assessed respectively.Results BMD at femoral neck was gradually decreasing with age.Area under curves (AUC) of receiver operating curve (ROC) of OSTA were 0.817 (female) and 0.797 (male) at femoral neck,the best cutoff values were-1.75 (female) and-1.70 (male).AUC of ROC for BMI was O.736 at femoral neck in male,which was similar to OSTA,and the best cutoff value was 22.9 kg/m2 in female,AUC of ROC for OSTA were higher than BMI both at femoral neck and lumbar spine.Conclusion Both OSTA and BMI have certain predictive value in screening osteoporosis,and OSTA is superior to BMI in female.The appropriate cutoff value of OSTA is-1.7,and the diagnosis cutoff of BMI is 23 kg/m2 for male and 21 kg/m2 for female.%目的 比较
