Bone mineral density measurements of adult males in Mersin: comparison of lumbar spine and femur

Abstract

AimWe aimed to compare lumbar and femoral neck bone mineral density (BMD) values of geriatric and non-geriatric adult male populations, to find the correlation and the rates of concordance-discordance between BMD values of these two anatomic regions within both age groups. MethodsTwo hundred and forty men were recruited and divided into two groups, geriatric (n = 126) and non-geriatric (n = 114). Lumbar spine (L1-4) and left femoral neck BMD were measured using dual-energy x-ray absorptiometry (DXA). Concordance, minor, and major discordance rates were determined. BMD values of these two age groups were compared. The correlations between BMD values of lumbar and femoral regions within both age groups were calculated. ResultsThe mean BMD of geriatric men was significantly lower than that of non-geriatric men (P < .05). The correlation between T-scores of L1-4 and femoral neck was significant in both groups (P < .05). In the geriatric group, the concordance, minor, and major discordance rates of T-scores were found as 51.6%, 42.8%, and 5.6%, respectively. In the non-geriatric group, the concordance, minor, and major discordance rates of T-scores were found as 61.4%, 35.1%, and 3.5%, respectively. ConclusionDXA was useful in comparing BMD of geriatric and non-geriatric men. Though the correlation between T-scores of L1-4 and femoral neck was found to be significant both in geriatric and non-geriatric men, minor or major discordances between these regions should be taken into consideration while evaluating DXA results of the patients.
