AbstractThe accuracy of BMD at distal radius was evaluated in terms of sensitivity, specificity, false negative, false positive, predictive value of a positive (osteoporosis) and a negative (normal) test for non- forearm osteoporosis. 278 women (150 osteoporotic and 128 normal) were measured for both distal radius bone mineral density (BMD) using Panasonic (DXA-70) dual energy X-ray absorptiometry (DEXA) and non-forearm BMD using Hologic (QDR-4500) DEXA on the same day. The results showed that mean age, menopause age, height and weight in the osteoporotic group were not different from the healthy group (p=0.168, 0.091, 0.274 and 0.097, respectively). Mean BMD of both distal radius and lumbar spine in the normal women was significantly higher than that in the osteoporotic group (p
