The first goal of our study was to examine the differences on disordered eating and alcohol consumption among heavy, occasional restrictors, and non-restrictors in a sample of 823 adolescents. The second goal was to analyze the relation of drunkorexia between unhealthy eating and alcohol use. Our results showed that heavy restrictors reported more eating disorder symptoms and alcohol use than occasional restrictors and non-restrictors. Similarly, occasional restrictors showed more unhealthy eating and drinking behaviors than non-restrictors. Both disordered eating and alcohol use were significant predictors of drunkorexia, supporting the argument of drunkorexia as an overlapping of dysfunctional eating and drinking patterns.

This study aimed to investigate the motivations underlying binge eating and binge drinking in a sample of 302 adolescents. Our findings showed that binge eating was significantly correlated with gender, environmental, emotional, and social eating. Hierarchical multiple regression analysis indicated that emotional and environmental eating were significant positive predictors of binge eating, whereas binge drinking was significantly correlated with enhancement, social, and coping motives. Only enhancement motives were significant predictors of binge drinking. Our results support the argument that the reasons underlying binge eating and binge drinking in adolescents may be similar and may perform the same function.
