#2-15E. Early Childhood Screen Time: A Longitudinal Link to Lower Academic Achievement (JNO, 2025)

How often are primary care physicians asked about the impact of screen time on a child's future academic success? This prospective cohort study from the TARGet Kids! collaboration addresses this critical question by examining the longitudinal association between young children's parent-reported total screen time and standardized academic achievement tests in elementary school. The study found that high levels of total screen time and TV/digital media exposure were consistently associated with lower achievement levels in reading and math in grades 3 and 6. Crucially, each additional hour per day of total screen time was linked to a 9% to 10% lower odds of achieving a higher academic level in Grade 3 reading and math, and Grade 6 math. However, clinicians must critically remember that this is an observational study, precluding definitive conclusions regarding causality, and relies heavily on parent-reported data, which may introduce self-report or recall bias. Nevertheless, these findings provide strong, practical evidence supporting the development of early, targeted interventions to reduce screen time exposure, offering clear guidance for pediatricians and family doctors counseling parents on promoting healthy screen use habits to enhance academic outcomes.
