Excessive smartphone use may increase the risk of Eating Disorders among young people.
A new study published in the Journal of Medical Internet Research has highlighted growing concerns around digital habits and mental health.
The research examined “Problematic Smartphone Use” (PSU), defined as a psychological dependence on mobile devices, and its impact on eating behaviours and body image. The analysis covered 35 studies involving more than 52,000 participants, with an average age of 17, indicating the trend is widespread.
Findings showed that young people who feel anxious without their phones or struggle to control usage are more likely to exhibit disordered eating patterns. These include emotional overeating, uncontrolled eating, and signs of food addiction, even without a formal diagnosis.
The study also identified a key threshold, noting that risks were significantly higher among those using smartphones for more than seven hours a day. High usage was also linked to increased dissatisfaction with body image, driven by constant exposure to idealised appearances online.
Researchers stressed the distinction between general screen time and PSU, which involves withdrawal symptoms, lack of control, and distress affecting daily life. They noted that while smartphones do not directly cause eating disorders, they act as a major contributing factor.
Beyond eating behaviours, excessive smartphone use has been associated with broader issues such as anxiety, depression, reduced physical activity, and lower productivity.
The study suggests that addressing digital habits should be part of prevention and treatment strategies.
Experts recommend setting limits on screen time, taking regular breaks, and encouraging offline activities to support both mental and physical well-being.
