Resumen:
19 Body composition and bone mineral density in men:Changes through decades of life and reference values J.M. Deferrari, S.R. Mastaglia, M.S. Parisi, M. Seijo,M.C. Ferna´ndez, A. Bagur, B. Oliveri Osteopatías Me´dicas, Hospital de Clínicas, University of Buenos Aires, Argentina Total and subregional body composition (BC) and bone mineral density(BMD)measurements performed by DXAare useful in clinical practice. OBJECTIVES: 1—To establish Total Body (TB) BC: Bone mineral content (BMC), lean mass (LM) and fat mass (FM) and BMD  reference values in healthy men from 20 to 79 years of age. 2—To analyze changes through these decades. POPULATION: 116 normal Caucasian male aged 20 to 79 years, with a body mass index (BMI) between 20–30 kg/m2. METHODS: BMD of TB and subregions (legs, arms, trunk, total spine and pelvis) and TB BC (BMC, LM and FM) and subregions (legs, arms and trunk) were determined by DXA (LUNAR-DPX-L). RESULTS: The changes from D3 (aged 20–29) to D8 (aged 70–79) were analyzed by ANOVA. A diminution in height (-6 cm, P < 0.03), and an increase in BMI (+2 kg/m2, P <0.01) were observed. There was a decline in TB BMD, area and BMC (6, 9, and 15%, respectively). TB fat mass showed an increment of 6.7 kg (P < 0.001) mainly due to trunk fat mass (+70%). TB lean mass  showed a decline of 5 kg (P <0.05) mainly due to a diminution in peripheral lean mass: 3 kg in legs (-16%, P < 0.0001) and 1.3 kg in arms (-9%, P < 0.002). CONCLUSIONS: Through the decades weobserved: 1—A slight (6%) diminution in DMO, with a higher diminution in area and BMC (9 and 15% respectively).2—An increase in  Total Fat Mass, predominantly in the trunk, that may have implications for the risk of Cardiovascular and metabolic syndromes, and a diminution in TB lean mass, predominantly in the legs, probably related to decreased physical activity and hormonal changes.  3—Total and subregional BMD and BC reference values were obtained. doi:10.1016/j.bone.2006.02.025
