Abstract
Cigarette Smoking is Associated With Suicidality in Bipolar Disorder
Ostacher M J~~LeBeau R T~~et al
In this propsective observational study of 116 individuals with bipolar disorder, the authors examined the association between smoking & suicidality as measured by Linehan’s Suicide Behaviors Questionnaire & prospective suicide attempts over a 9-month period. Impulsivity was measured. Smoking was associated with higher baseline Suicide Behaviors Questionnaire scores in univariate & adjusted analyses but was not significant after statistical adjustment for impulsivity in a regression model. A higher proportion of smokers at baseline made a suicide attempt during the follow-up period compared to nonsmokers. Smoking at baseline also significantly predicted a higher Suicide Behaviors Questionnaire score at 9 months. (26 refs.) JA
