Weekly work hours and health-related behaviours in full-time students

Using cross-sectional data from the 2003 Canadian Community Health Survey, this study examines whether the number of hours worked by full-time students aged 15 to 17 is associated with smoking, alcohol consumption, and physical activity. As well, longitudinal data from the National Population Health Survey were used to determine if work hours are related to the initiation of smoking and alcohol consumption, and to changes in physical activity over a two-year period.
