BACKGROUND: Eating disorders are serious psychiatric illnesses with high levels of suicidality and high comorbidity. However, no study has established the extent to which suicidality is uniquely associated with eating disorders rather than attributable to comorbid mood, anxiety, or substance use disorders. The current study examined whether unique associations between eating disorders and suicidality exist and whether potential associations differ by eating disorder diagnosis.
METHODS: Participants were women (n = 364) from the second stage of a large epidemiological study examining eating and health related attitudes and behaviors. The Structured Clinical Interview for Axis I diagnoses (SCID-I) was used to determine lifetime psychiatric diagnoses and lifetime suicidality.
RESULTS: A multiple regression model including eating and comorbid disorders indicated that bulimia nervosa (BN) was significantly associated with suicidality above and beyond risk predicted by comorbid disorders. No unique association was found for anorexia nervosa (AN) or eating disorder not otherwise specified while controlling for comorbidity.
CONCLUSIONS: BN is independently associated with suicidality, and findings emphasize the need to incorporate suicide risk assessment in standardized assessments of eating disorders.
