Psychopathology in severely obese women from a Canadian bariatric setting

Abstract

Purpose

Evidence suggests high rates of psychiatric disorders in bariatric surgery candidates (e.g. Mitchell et al., 2012), although no rigorous studies have examined the prevalence in a Canadian sample. Improved understanding of the prevalence of psychopathology among female patients is an important area of study, as females comprise approximately 80 percent of surgical candidates (Martin et al., 2010; Padwal, 2005). The purpose of this paper is to assess the prevalence of Axis I disorders and associations with quality of life in a Canadian sample of female bariatric surgery candidates.

Design/methodology/approach

Female patients (n=257) were assessed using a structured psychodiagnostic interview and completed a health-related quality of life questionnaire.

Findings

Results indicated that 57.2 percent of patients met DSM-IV-TR criteria for a lifetime psychiatric disorder and 18.3 percent met criteria for a current psychiatric disorder. Major depressive disorder was the most common lifetime psychiatric disorder (35.0 percent) and binge eating disorder was the most prevalent current psychiatric disorder (6.6 percent). Patients scored significantly lower than Canadian population norms on all domains of the SF-36 (all p's<0.001). Patients with a current Axis I disorder also reported significantly worse functioning on four mental health domains and one physical health domain (p's<0.01) compared to patients without a current Axis I disorder.

Originality/value

Results confirm high rates of psychiatric disorders in Canadian female bariatric surgery candidates and provide evidence for associated functional health impairment. Further study is needed to elucidate how pre-operative psychopathology may impact female patients’ post-operative outcomes.
