Eating disorders are associated with significant morbidity and mortality. The Internet is a popular medium for individuals with eating disorders to discuss and reinforce their affliction. However, the available literature on Internet usage and eating disorders is scarce, especially in the area of social media and smartphone application (“app”) usage.

To look at the Internet and smartphone app usage patterns of participants who presented with an eating disorder in Singapore, and whether it corresponded to severity of illness.

Individuals who presented to the Eating Disorders clinic at the Singapore General Hospital from 13th June 2013 to 20th December 2013 completed a self-reported questionnaire on Internet and app usage. They also completed the EDE-Q, EAT-26 and CIA 3.0.

Fifty-five participants completed the study. A total of 41.8% had anorexia nervosa, 34.5% had bulimia nervosa, and 9.1% were ED-NOS. 41.8% felt that apps helped to perpetuate their illness, while 32.7% felt that apps were helpful for recovery. Overall, any smartphone application usage was associated with younger age and greater eating disorder psychopathology and psychosocial impairment. While 30.9% had encountered eating disorder-related content on Facebook, only 12.75 visited Facebook groups related to eating disorders. For YouTube, “Cooking and Food” and “Beauty and Fashion” videos were among the top 3 types of videos that participants watched.

Internet and smartphone app usage is significant, and they are used to prolong or worsen eating disorder behavior in those with greater severity of illness. It is necessary to include interventions in this aspect as part of treatment.
