Study design: Secondary cross-sectional analyses of a cohort. %26lt;br%26gt;Objectives: To examine seasonal variation in total moderate-to-vigorous leisure-time physical activity (MV-LTPA), exercise and sport participation in a cohort of individuals with spinal cord injury (SCI). %26lt;br%26gt;Setting: Community (Ontario, Canada). %26lt;br%26gt;Methods: Participants with SCI (n=695) completed telephone interviews regarding their involvement in MV-LTPA along with social cognitive predictors of MV-LTPA. Logistic regression was used to predict the impact of season on participation in MV-LTPA, exercise and sport. Hierarchical linear regression was used to examine seasonal variation in min per day of MV-LTPA in the active sub-cohort (n=342) with a specific focus on exercise (for example, wheeling), and sport (for example, sledge hockey). %26lt;br%26gt;Results: Logistic regressions revealed that season did not predict whether participants engaged in MV-LTPA, exercise or sport. Linear regressions revealed that individuals in the active sub-cohort who completed the questionnaire during the winter reported engaging in less MV-LTPA than those who were interviewed in summer (beta(summer)=0.14, P%26lt;0.05). This pattern was observed for exercise (beta(summer)=0.16, P%26lt;0.05; R-2 change=0.018) but not for sport (beta(summer)=0.076, P=0.68; R-2 change=0.014). %26lt;br%26gt;Conclusion: Individuals with SCI report less exercise and total LTPA accrued during the winter months; sport was found to be an exception to this case.
