Study Suggests Prolonged Screen Time Linked to Higher Autism Symptoms Risk in Children

KUALA LUMPUR, March 18, 2026 — A new study conducted by researchers at the National University Hospital (NUH) has found that children who spend extended hours in front of digital screens are more likely to show symptoms associated with autism spectrum disorder (ASD), particularly in areas related to social interaction and communication.

The study observed patterns among children with significant screen exposure and noted that those who spent longer periods using phones, tablets, TVs, and other digital devices demonstrated behavioural characteristics that aligned more closely with autism‑related traits compared with peers who had more limited screen usage. Although the researchers stressed that the findings do not prove that screen time directly causes autism, the association has raised concerns among child development experts and caregivers alike.


Understanding the Study Findings

According to the research, children who were exposed to screens for extended periods daily exhibited greater challenges in:

  • Social communication skills
  • Interaction with peers and adults
  • Attention and behavioural expression

Researchers suggest that excessive screen use — particularly during early childhood, when neural pathways and communication skills are rapidly developing — might contribute to delays in language acquisition and social learning.

Health professionals emphasise that while the study shows a correlation between screen exposure and autism‑like symptoms, it does not conclusively prove that screens cause autism. Autism spectrum disorder is a complex neurodevelopmental condition with genetic and environmental influences that remain under active scientific investigation.


Expert Perspectives and Recommendations

Child development specialists say the study adds to global research suggesting that too much screen time could impact early development, particularly in skills gained through direct human interaction — such as eye contact, turn‑taking in conversations, and learning social cues.

Dr. Jane Tan, a paediatric consultant, explains: “Screens can be an engaging tool, but they shouldn’t replace real‑world interactions with caregivers and peers, which are essential for developing social and language skills.”

Many leading health organisations, such as the American Academy of Pediatrics, recommend limiting daily screen exposure in young children — especially those under 2 years old — and advise active parental supervision and engagement when digital media is used.


Context and Caution in Interpretation

It’s important to note that recent meta‑analyses and reviews of screen time research have found mixed results regarding neurodevelopment and ASD risk when controlling for variables like family environment and socio‑economic factors. Some studies suggest that prolonged screen exposure may be a marker of underlying developmental differences, rather than a direct cause of autism itself.

Experts caution against interpreting these results as definitive proof of causation, advising caregivers to consider a balanced digital environment while also seeking professional guidance if developmental concerns arise.


Implications for Parents and Caregivers

Given the study’s findings, experts recommend practical steps for families:

  • Set clear screen time limits, especially for toddlers and preschool‑aged children
  • Prioritise interactive play and human communication
  • Use digital content that is educational and age‑appropriate
  • Supervise screen use actively and engage children in off‑screen conversations

By adopting mindful digital habits and encouraging rich social engagement, parents can help support healthy childhood development while navigating the realities of modern screen use.
