Eating disorders and food addiction in men with heroin use disorder: a controlled study.

ABSTRACT

PURPOSE: We aimed to determine the prevalence estimates of binge eating disorder, bulimia nervosa, anorexia nervosa, and food addiction in men with heroin use disorder and a matched sample of control participants. METHODS: A group of 100 men with heroin use disorder, consecutively admitted to a detoxification and therapy unit, were screened for DSM-5 eating disorders, along with a group of 100 male controls of similar age, education, and body mass index. The Yale Food Addiction Scale (YFAS), the Barratt Impulsivity Scale-version 11, and the Eating Attitudes Test were used for data collection. Patients were also evaluated for various aspects of heroin use disorder (e.g., craving) using the Addiction Profile Index. RESULTS: Binge eating disorder that met DSM-5 criteria was more prevalent in patients with heroin use disorder (21%) than in control subjects (8%) (odds ratio 3.1, 95% confidence interval 1.3-7.3; p < 0.01). Food addiction based on the YFAS was also more common among men with heroin use disorder (28%) than among control participants (12%) (odds ratio 2.9, 95% confidence interval 1.4-6.1; p < 0.01). A current food addiction was associated with more severe craving and having a history of suicide attempts in the patients. CONCLUSIONS: Co-occurring binge eating disorder and food addiction are highly frequent in men with heroin use disorder. Screening for binge eating disorder and food addiction in patients with substance use disorder is important, as interventions may improve treatment outcome in this patient group.
