JMIR Mental Health: Excessive Smartphone Use Linked to Disordered Eating

A new study suggests that excessive smartphone use may be associated with poorer body perception and the development of unhealthy eating habits. Researchers found that individuals who spend a lot of time on their phones are more likely to experience body dissatisfaction and show signs of disordered eating, such as emotional overeating or a loss of control over food intake. The findings were published in JMIR Mental Health.

The researchers analyzed data from a large group of participants, comparing daily smartphone usage with psychological and behavioral indicators.

The study found that the more time a person spends on their phone, the higher the likelihood of symptoms of food addiction and other forms of disordered eating. This relationship was particularly pronounced among people who used their smartphones for more than seven hours a day.

Interestingly, participants did not have a clinical diagnosis of an eating disorder. Nevertheless, many displayed characteristic behaviors, such as uncontrolled eating or using food as a way to cope with stress and emotional challenges. At the same time, body dissatisfaction and critical self-perception increased among these individuals.

The researchers suggest that constant exposure to visual content online and on social media may play an important role. Users regularly encounter carefully edited images and “idealized” appearances, which can intensify social comparisons and foster unrealistic beauty standards. Such pressure often contributes to lower self-esteem and a more critical view of one’s own appearance.

However, the authors emphasize that the observed association does not prove a direct cause-and-effect relationship. It cannot yet be concluded that smartphone use directly causes body-image or eating behavior problems. Nevertheless, the findings highlight a potential risk and underscore the need for further research on how digital technologies and social media may impact users’ psychological health.
