ABSTRACT

OBJECTIVE: Binge eating disorder (BED), although relatively recently recognized as a distinct clinical syndrome, is the most common eating disorder. BED can occur as a separate phenomenon or in combination with other mental disorders, adding to the overall burden of the illness. Due to the relatively short history of recognizing BED as a distinct disorder, this review aimed to summarize the current knowledge on the co-occurrence of BED with other psychiatric disorders.

METHOD: This review adhered to the PRISMA guidelines. Multiple databases, such as MEDLINE, MEDLINE Complete, and Academic Search Ultimate, were used to identify relevant studies. Of the 3766 articles initially identified, 63 articles published within the last 13 years were included in this review. This systematic review has been registered through INPLASY (INPLASY202370075).

RESULTS: The most frequently observed comorbidities associated with BED were mood disorders, anxiety disorders and substance use disorders. They were also related to more severe BED presentations. Other psychiatric conditions frequently associated with BED include reaction to severe stress and adjustment disorders, impulse control disorder, ADHD, personality disorders, behavioral disorders, disorders of bodily distress or bodily experience, and psychotic disorders. Additionally, BED was linked to suicidality and sleep disorders.

DISCUSSION: The findings highlight the interconnected nature of BED with various psychiatric conditions and related factors, shedding light on the complexity and broader impact of BED on mental health and the need for appropriate screening and appropriately targeted clinical interventions.
