Global study links children’s screen time to developmental delays
A global study published in the renowned medical journal JAMA Pediatrics has revealed a negative link between children’s screen time and their overall development.
Based on this global data, researchers from the University of Calgary in Canada reviewed studies spanning decades that involved approximately 3 million children under the age of 18 across 64 countries.
The research found that excessive screen use was associated with deficits and delays in children’s learning abilities, speech patterns, behavioral traits, and emotional regulation.
According to the researchers, modern devices have heightened the risk. Unlike those of the past, today’s smartphones and devices are highly interactive and addictive, resulting in a more profound impact on children’s mental health.
💡 Expert Recommendation
Instead of completely banning devices, families should establish “screen-free” times—such as during dinner or before bedtime—to ensure children have adequate time for play, physical exercise, and sleep.
Medical experts have urged governments to issue guidelines regarding screen usage and to protect children from online risks.
Why it matters: As screens become increasingly embedded in daily life, understanding their developmental impact on children is critical. This study—one of the largest of its kind—provides strong evidence for parents, educators, and policymakers to reassess screen-time habits and prioritize healthy alternatives that support child development.
