The headlines said screens hurt kids more than poverty. The research says something more useful: what a screen replaces matters more than the clock.
A new review of research on nearly 2.8 million children in 64 countries has found that heavier screen use goes along with lower grades, weaker language skills and more emotional and behavioral difficulties.
Published Monday, September 28, in JAMA Pediatrics, the review pooled 23 earlier meta-analyses, which are studies that combine the results of many other studies. The team was led from the University of Calgary.
Some headlines, including in The Telegraph, said screens “damage children more than being born into poverty.” That is not what the study showed, and the real finding is more useful to parents.
What the researchers found
Higher screen use was linked to poorer overall academic achievement and weaker language development. It was also linked to more symptoms of anxiety and depression, more aggression and attention problems, and more trouble with peers.
The review found no clear link with scores in math, reading or science, though the authors said those subjects had been studied far less.
The researchers wrote that the strength of these links was “similar in magnitude to or larger than” those reported for other known predictors of child outcomes, such as socioeconomic status, parenting behavior and preterm birth. That one sentence produced the poverty headlines.
Why “worse than poverty” is the wrong takeaway
The study compared the size of statistical associations found in different bodies of research. It did not test screens against poverty head to head, and it did not show that screens cause the problems it measured.
Most of the underlying studies measured screen habits and wellbeing at the same moment. Professor Esther van Sluijs of Loughborough University called the review “high-quality” but said this design “cannot say much about whether higher screen use leads to poorer outcomes.”
Tatiana Íñiguez Berrozpe of the University of Zaragoza said the associations are real but “very small,” about 1 percent of the difference between one group of adolescents and another. She warned that the comparison with socioeconomic status “must be treated with caution,” because screen-time studies usually do not adjust for it at all.
The relationship also runs both ways. A 2025 analysis of 117 long-term studies of about 292,000 children under age 10, published in Psychological Bulletin, found that screen use predicted later emotional problems and emotional problems predicted more screen use. Both effects were small, and both were strongest for video gaming.
The better question: what is the screen replacing?
The review could not separate types of screen use. Van Sluijs said there was not enough data to draw conclusions about social media or gaming specifically.
Íñiguez Berrozpe put it plainly: the problem is often not screen use itself “but rather what I stop doing when I am engrossed in it, such as sleeping, taking part in physical activity, or socialising with family and friends.”
A video call with grandparents, homework on a laptop and two hours of late-night scrolling all count as screen time. They do not do the same thing to a child’s day.
The American Academy of Pediatrics said much the same in its policy statement released in January. One of its five guiding questions for families is now: what is digital media crowding out? Content quality and protecting sleep, play, physical activity and reading, it says, matter more than any single daily number.
The AAP adds a point many parents will find freeing. Apps are built with autoplay, endless feeds, notifications and rewards that make stopping hard, and the Academy says this design “lies largely outside of the control of individual families.” Your child is not weak-willed. They are up against products engineered to keep them there.
What parents can do this week
- Protect sleep first. The AAP recommends no devices in the bedroom and no screens in the hour before bed.
- Do a replacement check, not just a minute count. Is your child still getting enough sleep, movement, outdoor time, reading, homework time and face-to-face friendship? If yes, the number matters less. If no, start there.
- Turn off the hooks. Switch off autoplay and non-essential notifications, use do-not-disturb at night, and set app limits together rather than in secret.
- Treat different screen use differently. Homework, creative projects and calls with family are not the same as passive scrolling. Blanket rules feel unfair and are harder to keep.
- For young children, watch together. The AAP says educational content helps most when a caregiver watches and talks about it. It also cautions against handing a preschooler a phone to calm down, which is linked to weaker self-regulation.
- Add before you subtract. Sports, music, art, cooking and family games make limits easier to keep. The AAP calls this crowding in.
For rough boundaries, the AAP suggests under one hour a day for toddlers and preschoolers, and one to two hours a day, sometimes more, of entertainment media for school-age children and teens, depending on the child.
The takeaway
Data on nearly three million children point the same way as years of earlier research: heavy, low-quality, isolating screen use is worth taking seriously. The same evidence does not show that screens are the main cause of childhood distress, and it points to what a screen replaces as the more useful measure.
The goal is not a childhood without technology. It is a childhood where sleep, play, conversation and friendship still come first, and where parents know they are not fighting their kids. They are fighting the design of the products in their kids’ hands.
