The type of social media is a greater influential factor for orthorexia nervosa than the duration: a cross-sectional study

The type of SM, especially visual-based ones, has a significant influence on ON tendency than the duration. Not the increased time spent on SM but the use of Instagram, Pinterest, and TikTok were significantly correlated with increased ON tendency. Besides this, SM may also influence people regarding their purchase preferences, which results in increased ON tendency. Since the diagnostic criteria have not been definitively determined, the findings about the potentially influential factors are contradictory, and the prevalence is increasing; examining the influential factors with the general population is strongly recommended.
