- Design
- Umbrella review of meta-analyses with re-analysis
- Population
- 23 meta-analyses, 2,817,252 children aged ≤18 from 64 countries
- Primary outcome
- Academic, cognitive, socioemotional and mental health outcomes
- Effect
- Language r −0.14 (−0.18 to −0.10); academic r −0.15; externalising r 0.11; no link with executive function
An umbrella review in JAMA Pediatrics (28 September) re-analysed 23 meta-analyses covering 2.8 million children from 64 countries to quantify links between screen use and development.
More screen exposure was associated with lower academic achievement (r = −0.15) and language skills (r = −0.14), and with more internalising (r = 0.10) and externalising behaviour (r = 0.11). Associations with emotional problems (r = 0.30) and peer problems (r = 0.28) were larger but less precise. There was no association with executive function, or with mathematics, science or reading scores. Type of screen use, age and publication year changed some associations.
These are associations from observational studies and cannot separate cause from effect — children with emotional difficulties may use screens more. The effects are small for any individual child. The useful role in clinic is to ask about screen use as part of development and behaviour assessment, and to focus advice on what screens displace: sleep, talk, play and physical activity.
- Ask about screen time and content when assessing language delay or behaviour concerns.
- Focus advice on protecting sleep, conversation and active play rather than on a single number.
- Encourage shared, interactive use over solitary background viewing in young children.
- Present the evidence to parents as associations, not proven harm.
Why it matters
It gives parents a measured, evidence-based answer rather than alarm or dismissal.
Don't overread it
Observational associations only; the review cannot show screens cause these problems.
The statistics, in plain English
A correlation r of 0.10–0.15 is small: screen use accounts for about 1–2% of the variation in the outcome. Larger values for emotional and peer problems have wide intervals. All are associations that could run either way.
