Asthma and suicidal ideation with and without suicide attempts among adults in the United States: what is the role of cigarette smoking and mental disorders?

Cigarette smoking and concurrent mental health conditions may independently account for significant proportions of the association between asthma and suicidal ideation with attempts. More research is needed to further elucidate the mechanism of the remaining association between asthma and suicide attempts. Modification of smoking behaviors and effective treatment of depression, anxiety, alcohol abuse, and possibly asthma are important suicide prevention strategies.
