Abstract
OBJECTIVE: Maintaining life satisfaction may aid in multimorbidity resilience. As the prevalence of multimorbidity continues to rise in Canada, understanding modifiable factors that can influence life satisfaction among people with multimorbidity is warranted. This study aimed to examine the relationship between physical activity and life satisfaction among adults affected by multimorbidity. METHODS: Cross-sectional data from the 2015-2018 cycles of the Canadian Community Health Survey were used; 22,851 respondents with multimorbidity aged 20 years and older were included. Multiple linear regression models were used to investigate the relationship between physical activity (sedentary, somewhat active, moderately active, active) and life satisfaction for the whole population and for those having specific types of chronic conditions, controlling for self-perceived health status and sociodemographic factors. RESULTS: Respondents affected by multimorbidity who were somewhat active (β = 0.20, 95% CI: 0.08, 0.32), moderately active (β = 0.28, 95% CI: 0.13, 0.44), and active (β = 0.29, 95% CI: 0.17, 0.41) were more satisfied with life than respondents who had a sedentary lifestyle. The relationship between physical activity and life satisfaction was also found to be statistically significant in sub-populations of respondents affected by cancer, diabetes, chronic respiratory diseases, and mental health disorders but not cardiovascular diseases. CONCLUSION: Physical activity may contribute to better life satisfaction among adults with multimorbidity. As multimorbidity increases in Canada, further investigation on the relationship between physical activity and life satisfaction is warranted to help improve interventions to cope with the effects of multimorbidity.
