【 摘 要 】

BackgroundThere is a lack of studies investigating the possible mediating role of psychological factors, such as depression, anxiety and stress on orthorexic eating behaviors. Given that personality attributes might affect the manifestation of psychological disorders, it was hypothesized that depression, anxiety and stress mediate the relationship between impulsivity-related traits and orthorexic eating, noting that previous research had evaluated the role of depression as a mediator between impulsivity and other pathological eating behaviors. The study objectives were to explore the mediating effect of depression, anxiety, and stress, on impulsivity and orthorexia nervosa, and healthy orthorexia.MethodsThis cross-sectional study conducted between July and December 2019 recruited 519 Lebanese adults from seven community pharmacies randomly selected from a list provided by the Lebanese Order of Pharmacists.ResultsOur results showed that depression and anxiety were positively correlated with ON. We also found a notable gender difference in findings: higher anxiety and female gender were significantly associated with higher TOS healthy orthorexia, while higher stress was associated with lower TOS healthy orthorexia. Finally, higher urgency was associated with lower TOS healthy orthorexia, while higher perseverance was significantly associated with higher TOS healthy orthorexia. Depression and anxiety partially mediated the association between perseverance and ON while anxiety and stress partially mediated the association between urgency and healthy orthorexia.ConclusionOur study suggests that depression, anxiety and stress play a mediating role between impulsivity and orthorexia nervosa/healthy orthorexia. Our findings provide a ground for future investigations of impulsive behaviors, psychopathology, and orthorexia in different populations.
