Screen Time at Age 1 May Triple Autism Risk, Warns AIIMS Study

In

a breakthrough new study, the All-India Institute of Medical Sciences, New Delhi, has sparked widespread concern among parents and health experts, saying excessive screen time at the age of one may increase the risk of developing Autism Spectrum Disorder (ASD) by up to three times. While the findings do not prove direct causation, they do highlight an important link between early digital exposure and developmental health. According to experts, high screen usage impairs cognitive development and social interaction, with experts advising no screen exposure for children under 18 months and minimal, if any, before age.Also read: Can Diabetics Eat Watermelon?

Understanding the AIIMS study

The study observed young children and found that those exposed to higher levels of screen time during infancy - particularly around one year of age - showed a greater prevalence of autism-related traits by age three. This aligns with growing global research examining how early environmental factors influence brain development. According to the US Centers for Disease Control and Prevention (CDC), about 1 in 31 children is now diagnosed with autism. The World Health Organisation places the global estimate at around 1 in 100. AIIMS evaluated more than 2,000 children with autism, and nearly 80 per cent of them were found to have additional challenges, ranging from epilepsy and attention difficulties to sleep and behavioural issues. These layers make everyday life harder, not just for the child, but for caregivers as well. “Autism spectrum disorder is a neurodevelopmental condition that affects social interaction and communication. It begins early in life, sometimes within the first year. A key feature is repetitive behaviours and restricted interests. For example, a child may repeatedly flap their hands or walk on their toes. These actions are not connected to context and are seen as repetitive patterns,” said Dr. Shefali Gulati, Faculty In-Charge of Child Neurology Division in the Department of Paediatrics, AIIMS. She added that children with autism can engage with the world differently: "Children with autism may also focus intensely on specific parts of a toy rather than playing with it in a typical way. The term 'spectrum' is important; it means every child is different. Not all children show the same signs, and the severity also varies widely."

What is Autism Spectrum Disorder?

Autism Spectrum Disorder is a developmental condition that affects communication, behaviour, and social interaction. Symptoms can vary widely but often include delayed speech, reduced eye contact, repetitive behaviours, and difficulty engaging with others. Early diagnosis and intervention are crucial for improving long-term outcomes.

Why screen time matters in early childhood?

The first few years of life are critical for brain development. During this period, babies learn through real-world interaction - facial expressions, touch, sounds, and social bonding. Excessive screen exposure may interfere with these essential experiences. A few key concerns include:

• Reduced parent-child interaction, which is vital for emotional and language development
• Delayed speech and communication skills
• Overstimulation, which may affect attention and sleep patterns

Experts believe that screens cannot replicate the complexity of human interaction that infants need for healthy cognitive growth.

What do health guidelines say?

Global health bodies, including the WHO, recommend no screen time for children under 18 months, except for video calls. Instead, they encourage activities like storytelling, physical play, and responsive communication.

Balancing technology and child development

In today’s digital world, completely avoiding screens can be challenging. However, mindful usage is key. Parents can take simple steps to reduce risks:

• Avoid giving screens to infants under 18 months
• Limit screen exposure for toddlers and ensure it is supervised
• Prioritise interactive play and face-to-face communication
• Create screen-free routines, especially before bedtime

While the AIIMS study raises important concerns, experts emphasise that screen time is just one of many factors influencing autism risk. Genetics, environment, and overall lifestyle also play significant roles. Doctors say the takeaway is not to panic, but to be informed. Early childhood is a sensitive period, and small changes - like reducing screen exposure - can make a meaningful difference in a child’s development. The findings from AIIMS serve as a timely reminder for parents navigating a screen-filled world. By prioritising real-life interaction over digital engagement in the early years, families can better support healthy brain development and reduce potential risks associated with excessive screen time.
