Smoking and suicidality among psychiatric patients.
OBJECTIVE
This study investigated the relationship between smoking and suicidality among psychiatric patients.


METHODS
All psychiatric patients (N = 1,217) from Kuopio University Hospital in eastern Finland were examined for current smoking, suicidal ideation, previous suicide attempts, and other risk factors by using a cross-sectional, multivariate design.


RESULTS
The probability of at least one previous suicide attempt was 100% higher in current smokers than in nonsmokers. Smokers also had a 43% higher risk of experiencing mild to severe suicidal ideation than nonsmokers.


CONCLUSIONS
Current smoking was significantly related to suicidality in multiple logistic models, even after several confounding factors were controlled. The independence of this association seems possible, but the subject requires further research.
