Early electronic screen exposure and autistic-like symptoms

Links

Summary

Early and prolonged electronic screen exposure (≥3 hours/day) in children under 2 years old was associated with language delay, short attention span, and hyperactivity, with the light-melanopsin pathway proposed as a contributing mechanism. These findings suggest that lighting designers and pediatric care environments should consider limiting blue-light-rich screen exposure for young children, particularly without parental interaction.

Key Findings

Children viewing ≤3 hours/day of screens showed language delay and short attention span.
Children viewing ≥3 hours/day showed language delay, short attention span, AND hyperactivity.
66.6% of children had no parent-child interaction during screen exposure.
Speech delay and short attention span were reported in 100% of cases studied.
Hyperactivity was found in 66.6% of children in the sample.
