The use of food barcode scanner app among women: Associations with orthorexia, diet and emotions.

This cross-sectional study investigated the relationship between the use of food barcode scanner app (FBSA) and orthorexia, diet and emotions. A total of 1610 women from the general population were included in this study, 388 of whom were FBSA users. Participants completed questionnaires assessing socio-demographic and health characteristics, food barcode scanner use (Food Barcode Scanner App Questionnaire), orthorexia (Teruel Orthorexia Scale), food choice motivations (Food Choice Questionnaire), health anxiety (Health Anxiety Questionnaire), and emotional competence (Profile of Emotional Competence). The results showed no difference in socio-demographic characteristics between FBSA users and FBSA non-users. However, FBSA users scored higher on healthy orthorexia and health anxiety than non-users. FBSA users' food choice motivations were also more focused on natural food content, health, weight control and ethical concerns than non-users. Although no difference was found between FBSA users and non-users for orthorexia nervosa, orthorexia nervosa and pathological FBSA use scores were positively correlated. Moreover, health anxiety scores were positively correlated with FBSAQ "pathological use" subscale. While FBSA use may promote the adoption of a healthy diet, vigilance is required for individuals with orthorexic symptoms and health concerns. These two dimensions could be risk factors for problematic FBSA use.
