A sweeping umbrella review of 23 meta-analyses covering over 2.8 million children worldwide found that more screen time is linked to lower academic achievement, weaker language development, and greater emotional and behavioral problems. The associations held across TV, smartphones, video games, and social media. Researchers say screen use is a "modifiable factor" worth addressing in pediatric practice and policy.
A large-scale umbrella review published in JAMA Pediatrics has found that children and adolescents who spend more time in front of screens tend to perform worse academically and experience more emotional and behavioral difficulties. The analysis pooled data from 23 meta-analyses spanning over 2.8 million kids across 64 countries, making it one of the most comprehensive looks at this issue to date.
The findings cut across multiple domains — from classroom performance to mental health. Screen use was tied to increased depression, anxiety, aggression, and hyperactivity, while social media use specifically was linked to internalizing behaviors like withdrawal and low mood. Notably, no clear link was found between screen time and performance in math, science, or reading specifically.
Researchers say the evidence supports making screen use a routine conversation in pediatric visits and a target for broader policy action.
By the Numbers:
Why it matters: With screens now embedded in nearly every aspect of childhood, this review gives clinicians and policymakers robust, global evidence to act on — and a clear signal that managing kids' digital habits could meaningfully improve their well-being.
