Sedentary time reduction
Both environmental and educational strategies will be incorporated to reduce sedentary time. Study staff will provide participants with the Canadian 24-h movement guidelines (which encompass recommendations for sedentary behaviour, physical activity and sleep), as well as education on sedentary time and the associated health impacts, counselling and goal setting on strategies to reduce sedentary time throughout the intervention period. All participants will receive a Fitbit physical activity tracker to enable tracking of daily step counts, reminders to move after periods of sedentary behaviour, and goal setting related to these activities. Goals will be reviewed and progressed throughout the intervention.
