The aim of this study was to investigate the relationship between BMD and age at lumbar spine and proximal femur in Turkish males. Two hundred ninety healthy males (aged 20-59 years) were investigated. BMD of the lumbar spine had its peak at ages 30-39, however, the peak for the proximal femur was between the ages of 20 and 29. There was a significant decrease in BMD at proximal femur after these peak values with increasing age. In conclusion, there was a significant correlation between age and the proximal femoral BMD in males and age has a strong predictive power on proximal femur BMD score.
