About The Study: In this prospective cohort study of Canadian children recruited from primary care settings, high levels of total screen time and TV and digital media in young children were associated with lower achievement levels in reading and math on standardized tests in elementary school. Early interventions to reduce screen time exposure should be developed and tested to enhance academic achievement in elementary school.
