Résumé (anglais)

Physical activity is recommended in the management of arthritis. This thesis utilized the CCHS 2007-2008 to 1) determine what factors modify physical activity in explaining the likelihood of having arthritis; and 2) what demographic, behavioural and medical factors influence physical activity among people with arthritis. Light activity respondents were more likely to have arthritis (OR = 1.11; 95% CI: 1.03, 1.21) than sedentary respondents and the magnitude and direction of this relationship varied across gender and age groups. Obesity (body mass index > 30.0 kg/m2), high blood pressure (>/90mmHg, diastolic) and heart disease (ORs > 1.46) were associated with having arthritis. Among individuals with arthritis obesity or high blood pressure and smoking were associated with lower levels of activity. This study shows that individuals with arthritis are participating in light activity. Clinical management strategies for physical activity in arthritis should consider management of obesity, high blood pressure and heart disease.
