Abstract
Objectives. We examined the association between regular cigarette smoking and new onset of mood and anxiety disorders.
Methods. We used logistic regression analysis to detect associations between regular smoking and new-onset disorders among 34 653 participants in the longitudinal US National Epidemiologic Survey on Alcohol and Related Conditions (2001-2005). We used instrumental variable methods to assess the appropriateness of these models.
Results. Regular smoking was associated with an increased risk of new onset of mood and anxiety disorders in multivariate analyses (F(df)( = 5,61) = 11.73; P < .001). Participants who smoked a larger number of cigarettes daily displayed a trend toward greater likelihood of new-onset disorders. Age moderated the association of smoking with most new-onset disorders. The association was mostly statistically significant and generally stronger in participants aged 18 to 49 years but was smaller and mostly nonsignificant in older adults.
Conclusions. Our finding of a stronger association between regular cigarette smoking and increased risk of new-onset mood and anxiety disorders among younger adults suggest the need for vigorous antismoking campaigns and policy initiatives targeting this age group.
