The discriminating ability and relevance of clinical risk factors, quantitative ultrasound (QUS) variables, X-ray-based @entity79 ( @entity79 ) and @entity572 ( @entity572 ) measurements to evaluate the risk of @entity3604 in elderly Brazilian @entity1 were examined in this study. QUS at the calcaneus (Achilles +, Lunar), @entity572 and @entity79 measurements (DPX-L, Lunar) at several anatomical sites were performed in 275 postmenopausal Caucasian @entity1 . @entity1 with suspected secondary @entity170 were excluded. One hundred twenty-two (44.4%) @entity1 had had previous @entity3604 . All of the subjects were over 50 years old (range 53-93) and answered a questionnaire that included details concerning aspects of lifestyle, diet, hormonal factors and drug use. Lateral thoracic and lumbar radiographs were taken and an independent radiologist reviewed the X-rays for the presence of @entity174 . After adjustments for age, the most relevant risk factors to discriminate @entity1 with @entity3604 from normal non- @entity174 controls were Stiffness index (OR 2.8 per standard deviation; 95% confidence interval 2.3, 8.7), familial history of @entity173 (OR 2.6 per standard deviation; 95% confidence interval 2.2, 5.4), femoral neck @entity79 (OR 2.3 per standard deviation; 95% confidence interval 1.9, 4.2), age (OR 2.1 per standard deviation; 95% confidence interval 1.6, 2.8) and weight (OR 1.9 per standard deviation; 95% confidence interval 1.5, 2.6). @entity572 measurements did not associate significantly with the risk of @entity173 in this population. The ability of QUS measurements discriminate between @entity1 with @entity174 from those without was similar to, if not better, than X-ray-based @entity79 measurements. However, a combination of QUS and @entity79 measurements did not significantly improve @entity174 discrimination compared with either technique alone. Association of clinical risk factors with QUS or @entity79 measurements seems, on the other hand, to increase the sensibility to identify @entity1 at risk of @entity3604 .

Discriminatory ability of quantitative ultrasound measurements is similar to dual-energy X-ray absorptiometry in a Brazilian XXXX population with @entity3604 .
