High prevalence of shoplifting in patients with eating disorders.

PURPOSE: Shoplifting, prevalent in patients diagnosed with bulimia nervosa (BN), is a serious behavioral problem in eating disorder (ED) patients. However, little is known about its overall presence, etiology, and consequences. This study aimed to determine whether shoplifting occurs before or after the onset of ED and to investigate the prevalence and correlates of shoplifting in ED patients.

METHODS: This was a cross-sectional study of 284 treatment-seeking female patients aged 13-45 with EDs [171 anorexia nervosa (AN); 113 BN]. Shoplifting, impulsive behaviors (self-injury, suicide attempt, sexual promiscuity, alcohol, and illicit drug use), depression, self-esteem, and clinical features of EDs were assessed with an interview.

RESULTS: Lifetime shoplifting prevalence was 28.5% (81/284) with 70.4% (57/81) occurring before ED onset. Multivariate logistic regression analysis revealed that depression [odds ratio (OR), 2.63; 95% confidence interval (CI), 1.24-5.60], alcohol abuse (OR, 3.91; 95% CI 1.34-11.38), illicit substance use (OR, 14.42; 95% CI, 1.65-125.86), and self-esteem (OR, 0.90; 95% CI; 0.82-0.99) were associated with lifetime shoplifting, while illness duration, BN, and ED symptom severity were not.

CONCLUSIONS: Shoplifting is common in ED patients and precedes ED onset in most patients with a shoplifting history, although the causal relationship between shoplifting and EDs remains inconclusive. Shoplifting may be associated with impulsive behaviors (e.g., alcohol and illicit drug use), depression, and low self-esteem, but not with ED severity. Future research should focus on the unrecognized role of shoplifting as a marker to identify patients at risk of impulsive behaviors and consider treatment options.

LEVEL OF EVIDENCE: Level V, observational cross-sectional descriptive study.
