Prevalence of osteoporosis among above 60 years old subjects referred to Ayatollah Taleghani hospital in Tehran and its relationship with age and sex

Osteoporosis is a common bone disease that leads to disability and increased mortality due to bone fracture. This study was designed to evaluate the prevalence of osteoporosis and its association with gender and age in patients referred to elderly clinic in Taleghani hospital، Tehran. In this descriptive-analytic study، from 580 subjects referred to the elderly clinic of Taleghani hospital، 131 subjects that have BMD file were selected and densitometry results were collected from densitometry records. Data were analyzed by SPSS software using Chi-Square، T-test and linear regression. P<0. 05 was considered as significant. The overall prevalence of osteoporosis and osteopenia was 19. 9% and 36. 2 percent. The overall prevalence of osteoporosis was 29. 8% and 16. 8% in lumbar and femoral region، respectively. Mean lumbar and femoral T-score were -1. 692 ± 1. 50 and -1. 51 ± 1. 17، respectively. Association between age and osteoporosis in lumbar region and femoral region was significant (P value <0. 05). Association between gender and osteoporosis in lumbar region was significant but in femoral region was not significant. Linear regression between Lumbar and femoral T-score was +0. 632 (P value<0. 0001) Our finding revealed a higher prevalence rate of osteoporosis in patients referred to elderly clinic of Taleghani hospital and showed that age in femoral and lumbar region can predict lumbar and femoral density.
