title: Night eating syndrome in young adults: delineation from other eating disorders and clinical significance.
abstract: The Night Eating Syndrome (NES) is a recently described disordered eating style whose status in current diagnostic systems needs to be further clarified. The aim of this study was to increase knowledge about the clinical features of NES in a sample of 1514 young adults aged 18-26 years from the general population who participated in an anonymous Internet survey. We first examined characteristics of NES and tried to delineate it from healthy controls as well as from other eating disorders in terms of socio-demography, eating disorder pathology and general psychopathology. Second, we attempted to further clarify the clinical utility of the NES by assessing the degree of distress as well as impairment. Twenty (1.3%) participants with NES were identified and there was only modest overlap between NES and both Binge Eating Disorder (BED) and Bulimia nervosa (BN) according to questionnaire-based DSM-IV criteria. Compared to healthy controls, NES individuals reported more pronounced eating disorder pathology as well as general psychopathology (depressive symptoms, chronic social stress). NES seems to be associated with considerable distress and impairment. Implications for the validity and classification of NES are discussed.
