Abstract:
Objective To compare dual-energy X-ray absorptiometry T-score concordance between hip and lumbar spine, and to estimate the value of T-score of the hip for diagnosing osteoporosis in the elderly. Methods From September 2000 to May 2002, 123 males aged 60-89 years (average 72.0?7.4) and 137 females aged 60-88 years (average 67.3?6.1) were selected in the study based on the exclusion of subjects with apparent abnormalities affecting bone mass or taking medications which might affect bone metabolism. Detailed questionnaire included lifestyle factors such as smoking, drinking, exercise and dietary habits, etc. Radiographs of the thoracic and lumbar spine were taken. Patients' BMD were measured by DEXA (DMS, Challenger) at lumbar spine (L 2-4) and left hip in posterior-anterior projection. The right hip was scanned if patients had a history of fractures or any bone disease in the left hip. All data were statistically analysed using SPSS 8.0 system. Results The average T-scores of bone mineral density of the lumbar spine were higher than that of the hip in all male patients and in 65-, 85- age groups of female patients(P
