Background And Aims: Binge eating disorder (BED) is correlated with substance use. This study aimed to estimate the life-time prevalence of alcohol use disorder (AUD) among individuals with non-compensatory binge eating and determine whether their life-time prevalence of AUD is higher than in non-bingeing controls.

Design: A systematic search of databases (PubMed, Embase and Web of Science) for studies of adults diagnosed with BED or a related behavior that also reported the life-time prevalence of AUD was conducted. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol was followed. The protocol was registered on the International Prospective Register of Systematic Reviews (PROSPERO).

Setting: Studies originating in Canada, Sweden, the United Kingdom and the United States.

Participants: Eighteen studies meeting the inclusion criteria were found, representing 69 233 individuals.

Measurements: Life-time prevalence of AUD among individuals with binge eating disorder and their life-time relative risk of AUD compared with individuals without this disorder.

Results: The pooled life-time prevalence of AUD in individuals with binge eating disorder was 19.9% [95% confidence interval (CI) = 13.7-27.9]. The risk of life-time AUD incidence among individuals with binge eating disorder was more than 1.5 times higher than controls (relative risk = 1.59, 95% CI = 1.41-1.79). Life-time AUD prevalence was higher in community samples than in clinical samples (27.45 versus 14.45%, P = 0.041) and in studies with a lower proportion of women (β = -2.2773, P = 0.044).

Conclusions: Life-time alcohol use disorder appears to be more prevalent with binge eating disorder than among those without.

Background: Bulimia nervosa (BN) is a serious mental illness with impulsivity as a cardinal symptom. Impulsivity contributes to various other, often comorbid, mental disorders, such as attention deficit/hyperactivity disorder (ADHD) and borderline personality disorder (BPD). The aim of this study was to explore comorbidities of BN with ADHD and BPD as well as the contribution of impulsivity as an underlying trait linking these disorders.

Subjective eating disorder (ED) recovery has important clinical relevance. However, studies have focused on the perspectives of cisgender heterosexual individuals, which is notable given that sexual and gender minority (SGM) people often describe feelings misrepresented by prevailing ED conceptualizations. We examined eating pathology and psychosocial functioning across subjective recovery stages in SGM individuals ( = 196).

Redefining diagnostic parameters: the role of overvaluation of shape and weight in binge-eating disorder: a systematic review.

Introduction: Overvaluation of shape and weight is a critical component in understanding and diagnosing eating disorders. While the transdiagnostic model states that overvaluation of shape and weight is the core pathology of all eating disorders, this concept is not a criterion for binge-eating disorder. The lack of recognition of overvaluation of shape and weight may lead to overlooking, and consequently failure to address this construct during treatment.

Early life trauma has been shown to facilitate habitual behavior, which may predispose individuals toward perpetuating maladaptive behaviors. However, previous investigations did not account for other traumatic childhood experiences like racial/ethnic discrimination exposure, nor have they examined the interaction of trauma and habits on real-world adverse outcomes. To examine these effects, we recruited 96 young adults (20.

Introduction: Binge Eating Disorder (BED) has high lifetime prevalence rates, low treatment success rates, and high rates of treatment dissatisfaction, early discontinuation of care, and recurrence. Complementary and integrative health (CIH) interventions (non-mainstream practices used with conventional approaches for whole-person treatment) hold potential to overcome many treatment barriers and improve BED treatment outcomes. Some CIH interventions have empirical support for use in eating disorders.
