Previous issue date: 2013-03-22 / Changes in bone mass occur with aging and are related to lifestyle, such as physical activity and occupational activity professional. OBJECTIVES : Evaluate the variation in bone mass at the lumbar spine and proximal femur of S?o Lucas Hospital (HSL) doctors of Pontif?cia Universidade Cat?lica do Rio Grande do Sul (PUCRS), Brazil related to the study released in 2006. METHODS : Longitudinal and observational study with male doctors. It was applied a questionnaire with data on changing lifestyle habits in relation to physical activity for the 2006 study. This study used the DXA equipment HOLOGIC WI with analysis of the lumbar spine, femoral neck and total femur. For the analysis this study used the Student t test and chi-square. Values were significant of p≤0,05. RESULTS : A total of 22 physicians with an average age of 64,0?4,9 yeras. Regarding to physical activity 14 (63.6%) perform 2x/week or less and 8 (36.4%) perform physical activity greater than or equal to 3x/week. There was a gain from 2006 to 2012 in T-score of the lumbar spine of -0.26 ? 1.41 to 0.04 ? 1.47 (p = 0.015). There was no change in BMD of the lumbar spine. In the femoral neck BMD was reduced from 0.79 ? 0.10 to 0.74 ? 0.11 (p <0.001) and T-score of -1.75 ? 0.93 to -1.33 ? 0 , 82 (p <0.001) and total femur from 0.96 ? 0.10 to 0.92 ? 0.10 (p <0.001) and T-score of -0.90 ? 0.75 for -0, 64 ? 0.70 (p <0.001). There was no difference regarding the variation of BMD and frequency of weekly physical activity (≤ ≥ 2x/week or 3x/week) of the values of BMD at lumbar spine (0.01 ? 0.04 vs 0.03 ? 0.09; p = 0.547), femoral neck (-0.05 ? 0.05 vs. -0.06 ? 0.06, p = 0.759) and total femur (-0.04 ? 0.04 vs. -0.06 ? 0 , 04, p = 0.256). There was an association between age and variation of total T-score of lumbar spine and proximal femur (r = 0.500, p = 0.018). CONCLUSION : Regarding the 2006 study there was a reduction in BMD of the femoral neck and total femur and increased total T-score. There was no variation in BMD in relation to physical activity weekly. / INTRODU??O : Altera??es da massa ?ssea ocorrem com o envelhecimento e est?o relacionadas a quest?es individuais como, estilo de vida, falta de atividade f?sica, envolvendo tamb?m, atividade ocupacional profissional. OBJETIVO : Avaliar a varia??o da massa ?ssea da coluna lombar e f?mur proximal em um grupo de m?dicos. M?TODOS : Estudo longitudinal e observacional com m?dicos masculinos do Hospital S?o Lucas (HSL) da Pontif?cia Universidade Cat?lica do Rio Grande do Sul, (PUCRS), Brasil em rela??o ao estudo realizado em 2006. Foi aplicado question?rio com dados relativos ? mudan?a de estilo de vida em rela??o ao h?bito de atividade f?sica para o estudo de 2006. Utilizou-se o equipamento DXA HOLOGIC WI com an?lise da coluna lombar, colo do f?mur e f?mur total. Para a an?lise foi utilizado o teste t de Student e o teste do Qui-quadrado. Foram significativos os valores de p≤0,05. RESULTADOS : Foram avaliados 22 m?dicos com idade m?dia de 64,0?4,9 anos. Com rela??o ? atividade f?sica 14 (63,6%) realizam 2x/semana ou menos e 8 (36,4%) realizam atividade f?sica maior ou igual a 3x/semana. Houve um ganho de 2006 para 2012 no T-score da coluna lombar de -0,26?1,41 para 0,04?1,47 (p=0,015). N?o houve mudan?a na BMD da coluna lombar. No colo do f?mur houve redu??o da BMD de 0,79?0,10 para 0,74?0,11 (p<0,001) e do T-score de -1,75?0,93 para -1,33?0,82 (p<0,001) e no f?mur total de 0,96?0,10 para 0,92?0,10 (p<0,001) e do T-score de -0,90?0,75 para -0,64?0,70 (p<0,001). N?o houve diferen?a em rela??o ? varia??o da BMD e freq??ncia de atividade f?sica semanal (≤ 2x/semana ou ≥ 3x/semana) nos valores da BMD da coluna lombar (0,01?0,04 vs 0,03?0,09, p=0,547), colo do f?mur (-0,05?0,05 vs -0,06?0,06, p=0,759) e f?mur total (-0,04?0,04 vs -0,06?0,04, p=0,256). Houve associa??o entre a idade e varia??o do T-score total da coluna lombar e f?mur proximal (r=0,500; p=0,018). CONCLUS?O : Em rela??o ao estudo de 2006 ocorreu uma redu??o na BMD do colo e f?mur total e aumento do T-score total. N?o houve varia??o na BMD em rela??o ? atividade f?sica semanal.
