Este estudo propõe analisar quais variáveis se associam com a dificuldade no acesso de idosos com deficiência aos serviços de saúde. Trata-se de um estudo observacional analítico de caráter transversal, com uma amostra de 244 idosos com deficiência. Foram agrupados dados pertinentes ao perfil socioeconômico, à caracterização da deficiência e às condições de acessibilidade aos serviços de saúde. Para análise estatística descritiva e analítica dos dados, foi utilizado o software Statistical Package for the Social Science, versão 11.0. As variáveis de proteção para a dificuldade em ser atendido nos serviços de saúde foram: ausência de esgotos, bueiros, dejetos, sacos de lixos, ou pisos quebrados; ausência de degraus nas calçadas e existência de calçamento; presença de transporte; facilidade na marcação de consultas; e o baixo tempo de espera para ser atendido. O somatório dos fatores expostos mostra que as barreiras arquitetônicas e situação atual de atenção à saúde precisam ser adequadas, visando o ingresso e utilização plena dos idosos com deficiência aos serviços de saúde.

Introduction: The increase in body fat is a natural and progressive process with aging, allowing fat infiltration in ectopic sites, such as skeletal muscle, which disrupts its function. Objective: To evaluate the association between body composition, fat infiltration into the low back multifidus muscles, and history of low back pain. Methods: This is a transversal and qualitative study that included young adult subjects of both sexes, and excluded individuals with neurological and musculoskeletal disorders and pregnant women. Fat infiltration into the multifidus and cross section area by magnetic resonance imaging; body composition by Dual-energy X-ray absorptiometry (DXA), and physical activity level determined by the International Physical Activity Questionnaire (IPAQ) were evaluated. The sample was divided by sex and. Pearson and Spearman's correlation and stepwise linear regression were performed. For this study, a p<0.05, a level of significance of 5% and confidence interval of 95% were adopted. Results: Thirty-two individuals were evaluated (59.37% women; 40.63% men). There was a correlation between fat percentage and total cross-sectional area (CSAtotal) (r=0.525; p=0.021), in women, and with lean abdominal mass (r= −0.648; p=0.017) and Body Mass Index (BMI) (r= −0.644; p=0.018) in men. There was also an association, in women, between fat percentage and cross section area (R2=0.275; p=0.021; CI=0.364 − 3.925) and, in men, with lean abdominal mass (R2=0.420; p=0.017; CI: −9.981- [-1.235]). Conclusion: There was correlation between fat percentage in the multifidus and CSA in women, and lean abdominal mass and BMI in men. There was also an association between fat percentage and cross section area in women, and lean abdominal mass in men. However, there was no evidence of any correlation between pain and low back dysfunction. Level of evidence I; Diagnostic studies - Investigating a diagnostic test.
