Résumé (anglais)

Purpose The aim of this study was to compare patterns of PA and its potential correlates in individuals with BD to the general population using a representative sample of Canadians. Methods We used data from the 2002 Canadian Community Health Survey 1.2, a national, cross-sectional survey focusing on mental health and addiction (n = 36,984). We compared PA levels among individuals with BD (n = 831) to those diagnosed with major depression (n = 4713) and those with no identified mood disorder (n = 31,834). Using multivariable logistic regression, we then compared independent effects of sociodemographic and clinical factors in active and inactive BD individuals stratified by relative weight status. Results There were no differences in the proportion of individuals characterized as active, moderately active or inactive among individuals with BD, major depressive disorder or the general population. No sociodemographic or clinical variables were related to PA in individuals with BD, and the relationships between these variables and PA level were not different than those observed in the general population. BD status was independently associated with being overweight (OR = 1.26, p = 0.03). An interaction between BD status and PA was also observed (OR = 1.12, p = 0.005), suggesting a reduced role for PA in reducing the risk of being overweight in person with BD. Conclusions The results suggest that levels of self-reported PA are not lower among people with BD living in the community than in the general population. Future research should assess levels of PA using objective measures and determine whether PA improves psychosocial outcomes in this population.
