This controversy is addressed here with data from the nationally representative National Comorbidity Survey-Replication (NCS-R). Assessments were made of 12-month smoking, suicidal behaviors (ideation, plans, attempts), and DSM-IV disorders (anxiety, mood, impulse-control, and substance use disorders). Statistically significant odds ratios (2.9 -3.1) were found between 12-month smoking and 12-month suicidal behaviors. However, the associations of smoking with the outcomes became insignificant with controls for DSM-IV mental disorders. Although clear adjudication among contending hypotheses about causal mechanisms cannot be made from the cross-sectional NCS-R data, the results make it clear that future research on smoking and suicidal behaviors should focus more centrally than previous research on mental disorders either as common causes, markers, or mediators.engacceso cerradoarticle5Instituto Nacional de Psiquiatría Ramón de la Fuente Muñiz369-377Philadelphia195DUTY ARMY SOLDIERSPSYCHIATRIC-DISORDERSNICOTINE DEPENDENCECIGARETTE-SMOKINGUNITED-STATESFAGERSTROM TESTSUBSTANCE USEFOLLOW-UPNCS-RRISKepidemiologymental healthmental disordersnicotinesmokingsuicidal ideationsuicide planssuicide attempts
