12-Year-Olds with Smartphones Are More Likely to Develop Eating Disorders by 14, Study Finds
The study found 70% of 12-year-olds had phones, and 24% later reported at least one eating-disorder symptom.
A study published Friday in JAMA Network Open found that 12-year-olds who own smartphones are more likely to develop eating disorder symptoms by age 14.
Jason Nagata, an associate professor at the University of California, San Francisco, noted that smartphones expose children to curated, filtered content fueling body dissatisfaction and poor self-esteem.
Data from the Adolescent Brain Cognitive Development Study shows 70% of 12-year-olds own phones; 24% of those reported eating disorder symptoms at 14, compared to less than 16% of non-owners.
Mitch Prinstein, a professor at the University of North Carolina at Chapel Hill, suggests delaying phone access by six months or a year could benefit children's mental health and reduce body image issues.
Nagata recommends that parents implement 'additional guardrails,' such as limiting app downloads and keeping devices out of bedrooms, to monitor children's digital exposure and discuss online experiences.
