Cigarette smoking and its relationship to other substance use among eating disordered inpatients¹

Objective: The present study examines prevalence rates of tobacco, caffeine, alcohol and other substance use and abuse among eating disordered inpatients and compares smokers (regular vs occasional vs non-smokers) and eating disorder (ED) subtypes [anorexia nervosa (AN) vs bulimia nervosa (BN); restrictors vs purgers] on substance use behaviors, family history, depressive symptoms and impulsivity. Method: Participants were 100 ED inpatients who completed assessment upon treatment entry. Results: A high incidence of regular cigarette smoking (29%) and occasional smoking (13%) was detected and associations were found with caffeine abuse, alcohol and marijuana use, family history and depression. BNs were more likely to smoke occasionally and use alcohol than ANs, while Purgers demonstrated higher caffeine and alcohol use than Restrictors. Discussion: Comprehensive assessment and intervention for smoking, caffeine and other substance use among ED patients is clearly indicated.
