Early Smartphone Ownership Linked to Higher Risk of Eating-Disorder Symptoms in Teens

Data from the nation’s largest longitudinal child-health study were examined to explore the relationship between early smartphone use and later eating-disorder indicators. Adolescents who possessed their own device at twelve years old were significantly more likely to report at least one symptom—such as binge-eating episodes or linking self-worth to weight—by the time they turned fourteen, compared with peers who did not own a phone.

While the findings demonstrate a statistical association, the researchers caution that the smartphone itself may not be the direct cause, and a solitary symptom does not constitute a clinical diagnosis. Jason Nagata and his team suggest that unfettered access to appearance-focused social-media content could be a contributing risk factor. The study adds to a growing body of research linking early digital exposure to mental-health challenges, including depression, obesity and sleep problems. Nagata recommends that parents set clear usage rules, keep devices out of bedrooms, and actively monitor their children’s online activity.
