The profile of bone mass in physicians: an observational study
Abstract
Changes in the bone density occur during the aging process, being usually related to lifestyle, such as physical activity (PA) and professional occupation. This observational, cross-sectional study aims to check the bone mineral density (BMD) of the lumbar spine and proximal femur of 22 male individuals, all professionals of the health and medicine area, aging in average 64.0 ± 4.9 years. A DXA HOLOGIC WI equipment was used in this study, programmed with software for lumbar spine, femoral colon and total femur observations. Statistic software SPSS 18.0 for Windows was used to perform the necessary descriptive statistics. All participants signed a free consent declaration and the study was submitted and approved by the Research Ethics Committee at PUCRS under the license number 11/05713. The results showed the lumbar spine BMD at 1.08 ± 0.17 with T-score 0.04 ± 1.47; femoral colon BMD at 0.74 ± 0.11 with T-score -1.33 ± 0.82; total femur BMD at 0.92 ± 0.10 with T-score -0.64 ± 0.70. A portion of 31.8% (7) of the subjects were classified within the normal range; 59.1% (13 individuals) were diagnosed with some degree of osteopenia; finally, 9.1% (2 subjects) were classified as osteoporosis carriers. These findings suggest that professions which provide low levels of physical activity may represent a predisposing factor to decreased bone mineral density. Therefore, these professionals should be encouraged to compensate their sedentary lifestyle with moderate physical activity combined with their work routine. It is noteworthy that public policies addressing physical activity and workout should reach a larger portion of the population.
