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.

Background. Poor executive functions are associated with dysregulated eating and greater caloric intake in healthy samples. In parallel, findings suggested that sleep deprivation impairs executive functions.
Methods. We investigated whether partial sleep deprivation impairs executive functions in individuals reporting binge eating (BE, N = 14) and healthy controls (C, N = 13). Switch cost and backward inhibition were measured using the Task Switching Paradigm after a habitual night of sleep and after a night of partial sleep deprivation.

Perfectionism is a multidimensional personality trait that encom- passes two higher-order dimensions: Perfectionistic Strivings (i.e., the strive to achieve exceedingly high standards) and Perfectionistic Concerns (i.e., negative self-evaluation and fear of failure). Both dimensions are related to eating disorders (EDs) in clinical and community adults. The association between perfectionism and EDs has also been observed in children but, to date, no review has summarized the relevant empirical findings with children under the age of 14.
