Background: With the prevalence of osteoporosis in men increasing, the mortality and morbidity of fractures is higher than in women. But there are only a few studies about BMD in Korean men. In this study, we measured BMD at the lumbar spine and the femur to find the differences and discordance rate between these sites with age.

Methods: From January 2000 to May 2008, we measured height, weight and BMD of different skeletal sites by DEXA in 314 subjects seen at one hospital. The subjects had no history of diseases and fractures. Factors affecting BMD were analyzed via ANOVA, Chi square test and Pearson Correlation.

Results: The BMDs of L1, L2, L3, L4, femur neck, Ward’striangle and trochanter were 1.003±0.160, 1.086±0.175, 1.137±0.182, 1.180±0.193, 0.935±0.133, 0.740±0.163 and 0.819±0.113, respectively. The prevalence of osteopenia and osteoporosis increased with age. L2 spine and femur (any site) showed negative correlations with age. The discordance rate between lumbar spine and femur was 43.9%. The BMDs of L3 and L4 spine were low in men who smoked.

Conclusions: The BMDs of L2 spine and all sites of femur decreased with age, but other lumbar vertebrae showed no correlations because of higher osteophytes in men. The prevalence of osteoporosis was highest for men in their 70s. Diagnostic rate by femur increased with age. Thus, we conclude that it might be useful to check BMD in men in their 70s, and to monitor BMD of femur with increasing age. The BMD of lumbar spine was low in smoking men.
