INFLUÊNCIA DA IDADE, IMC E ATIVIDADE FÍSICA NA FUNCIONALIDADE E CAPACIDADE PARA O TRABALHO EM PESSOAS COM OSTEOARTRITE DE JOELHO

Abstract

Among the risk factors indicated for knee osteoarthritis, age and high BMI are of great concern. The study aimed to identify which factors between age, obesity and physical activity practice the most impact on work ability and functionality in people with knee osteoarthritis. People over 18 years of age with knee OA were recruited from the community. All participants answered the following questionnaires: sociodemographic and clinical; Western Ontario and McMaster Universities Osteoarthitis Index (WOMAC); Ability to Work Index (ICT); and International Physical Activity Questionnaire (IPAQ). The following physical performance tests were also performed: 40 meter walk test (40m TC); Test of going up and down stairs (TEladder); and 30s sit and stand test (TSL30s). We evaluated 45 people with knee OA, mean age of 61.2(8.2) years, M(SD). Multivariate linear regression analysis revealed that physical activity was significantly associated with functionality (self-report and performance) (p<0.05) and WAI (p<0.05). A significant association between BMI and functionality was also observed (p<0.05). There was no association between BMI and WAI (p>0.05). There was also no association between age and functionality or WAI (p>0.05). The results of this study suggest that the practice of physical activity can contribute, even more than other factors such as BMI and age, to the improvement of functionality and ability to work in people with knee OA.
