Association between the bi-dimensional aspect of orthorexia and healthy behaviors among lebanese adolescents
BMC psychiatry(2022)
Abstract
Background Recently, there has been a blooming focus on “eating healthy and clean”, with the ideal of being healthy becoming a popular lifestyle trend. Previous research suggested the presence of two forms of orthorexia: Orthorexia Nervosa (OrNe) and Healthy Orthorexia (HeOr). Taking into consideration that orthorexia thoughts are led by the desire to reach an optimal physical health, the dedication to a healthy living may require healthy lifestyle habits: smoking cessation, moderate alcohol intake, and increased physical activity. The main study aim was to determine, among Lebanese adolescents, the association between healthy behaviors and the two likely forms of orthorexia (OrNe and HeOr), given that the adolescent phase is a risky period in the development of eating disorders. Methods A cross-sectional study, conducted between January and April 2022, enrolled 444 adolescents aged between 14 and 18 years, with an equitable random sample from all the Lebanese governorates (mean age 16.23 ± 1.15 years; 60.1% females). The Teruel Orthorexia Scale (TOS) was used to assess orthorexic eating tendencies. The Lebanese Waterpipe Dependence Scale, the Fagerström Test for Nicotine Dependence and the Alcohol Use Disorder Identification Test scales, all validated in adolescents, were used to evaluate the association between orthorexia and healthy behaviors. Results Higher TOS OrNe scores were significantly and highly correlated with the TOS HeOr scores ( r = 0.68; p < 0.001). In the bivariate analysis, waterpipe smoking was weakly but significantly associated with more OrNe, whereas more physical activity was significantly and moderately associated with more HeOr. After adjusting over all sociodemographic characteristics, other behaviors and the other dimension of orthorexia, more alcohol use disorder was significantly but strongly associated with higher OrNe, whereas more physical activity remained significantly associated with higher HeOr. Conclusion In light of our results, OrNe and HeOr might be considered as different entities, mainly in their associations with alcohol consumption and physical activity. This supports the hypothesis of OrNe being a new form of eating disorder, whereas HeOr possibly showing protective characteristics. Orthorexia is still a topic of controversy, especially in the probable presence of two facets that are still difficult to differentiate.
