Global study links high screen time to poorer child outcomes
A major review of data from over 2.8 million children in 64 countries suggests high screen usage correlates with worse developmental results.
Study scope and findings
Researchers examined information on more than 2.8 million children across 64 nations to assess digital exposure impacts. The analysis found that elevated screen time affects academic achievement and emotional well-being in ways comparable to parental behaviour or premature birth. This umbrella review summarised results from previous large reviews published in the journal JAMA Pediatrics.
Specific developmental risks
Higher usage of gaming, social media and streaming services was linked to lower academic achievement and language development issues. Children with longer durations of digital use showed less favourable outcomes across multiple measured domains of their health. The study covered various devices ranging from smartphones to television sets.
Expert caution on limits
Some experts noted the report has limitations and stated it does not support screens as the main cause of adolescent distress. Researchers clarified that while impacts are significant, they are similar in magnitude to other known factors like family wealth.
