Resumen:
A precise assessment of bone mineral density (BMD) and body composition can be performed using dual-energy
X-ray absorptiometry (DXA). Values of body composition for males would be useful to evaluate the occurrence of
alterations in body composition in a number of diseases. The objectives of this study were to establish BMD and
body composition values in healthy men and to analyze age-related changes. BMD and body composition of total
body and subareas were determined in 116 healthy men (aged 20e79 yr) using DXA. Comparison between
20e29- and 70e79-yr-old men showed that older subjects were shorter ( p!0.03), and had a higher body mass index
( p!0.01). Fat mass increased (þ46.7%; p!0.001) especially in the trunk. Lean mass (LM) decreased (9.4%;
p!0.05) mainly in the arms and legs. Bone mineral content (BMC) and BMD decreased (15.3% [p!0.001],
6.3% [p!0.05], respectively). Correlation was observed between BMC and LM (r50.7, p!0.01). Values of
BMD and body composition in healthy men were obtained. A relation was observed between bone mass and body
composition, suggesting that the age-related decrease in LM may be associated to bone mass loss. Further studies
should be conducted to elucidate the role of body composition in the occurrence of osteoporosis in men.
