Giving a twelve year old their first smartphone may do more than just keep them connected with friends; it could significantly increase their risk of developing eating disorder symptoms. According to a new study published in JAMA Network Open, researchers found that preteens who owned their own devices at age twelve were notably more likely to report disordered eating by the time they reached fourteen compared to peers who waited longer for a phone. Drawing from a massive survey of nearly nine thousand American adolescents, the data revealed that twenty four percent of early smartphone owners showed symptoms of disordered eating two years later, while less than sixteen percent of those without phones experienced similar issues.
Dr. Jason Nagata, the lead author and an associate professor of pediatrics at the University of California, San Francisco, explains that these devices act as portals to a constant stream of appearance focused content. While puberty naturally pushes children toward comparing themselves to others, smartphones expand that circle beyond immediate classmates to global influencers. These highly curated and filtered images often project unrealistic beauty standards, leading many tweens to tie their self worth directly to their weight or engage in restrictive dieting and excessive exercise to mirror what they see on screen.
The findings suggest that timing is everything when introducing technology into a child’s life. Experts like Dr. Mitch Prinstein from the University of North Carolina at Chapel Hill note that even delaying access by six months or a year can yield benefits for adolescent mental health. Although most social media platforms officially require users to be thirteen, Nagata’s previous work shows that roughly two thirds of eleven and twelve year olds already have accounts on sites like TikTok and Instagram, bypassing safety guidelines before they are emotionally equipped to handle the pressure.
While there is no single magic date for handing over a device, researchers urge parents to implement strict guardrails rather than giving children unrestricted digital freedom. Recommendations include limiting downloadable apps, banning phones from bedrooms, and maintaining active involvement in their children’s online experiences. By fostering open conversations about digital literacy and monitoring changes in how kids talk about their bodies or food, parents can help mitigate the risks inherent in today’s hyper connected world.
