28 The effect of screen time on cardiometabolic risk in young children: A longitudinal cohort study

摘要

Young children in Canada do not meet the current screen time recommendations (< 1 hour for children 3 to 4 years; < 2 hours for children 5 years and older). While increased screen time is associated with physical and psychological health consequences in children, very little is known regarding the association with cardiometabolic risk (CMR) in young children. This study defined screen time as the use of TV, DVD/video, computer/laptop, video games, and handheld devices (e.g., cell phone, iPad Touch, iPad, etc.) on a typical weekday and a weekend day.
