Longitudinal association between tobacco use and the onset of depressive symptoms among Swedish adolescents: the Kupol cohort study.

ABSTRACT: Tobacco use in adolescence has been linked to the onset of depressive symptoms, but results of previous studies are inconsistent. The aim of this study was to clarify if tobacco use during early adolescence may affect the short-term onset of depressive symptoms. The study is based on Swedish Kupol study (3959 students).
