High screen time linked to poorer developmental outcomes in children, major study suggests

A comprehensive global study published in JAMA Pediatrics, involving 2.8 million children across 64 countries, suggests that high screen exposure is significantly linked to lower academic achievement and developmental challenges. Researchers found that excessive use of digital devices for gaming, social media, and streaming correlates with language development issues, as well as increased internalizing and externalizing behaviors, such as anxiety, depression, and aggression. The study highlights that these impacts are comparable in magnitude to other established developmental factors like socioeconomic status and premature birth. While experts acknowledge the study's high quality, some caution that screen time should not be viewed as the sole cause of adolescent distress, noting that the research cannot fully differentiate between specific types of digital engagement. The findings suggest that screen usage is a modifiable factor that may influence children's overall wellbeing across multiple domains.
