Information about the epidemiology of such behavior is important for policy-making and prevention. The authors reviewed government data on suicide and suicidal behavior and conducted a systematic review of studies on the epidemiology of suicide published from 1997 to 2007. The authors' aims were to examine the prevalence of, trends in, and risk and protective factors for suicidal behavior in the United States and cross-nationally. The data revealed significant cross-national variability in the prevalence of suicidal behavior but consistency in age of onset, transition probabilities, and key risk factors. Suicide is more prevalent among men, whereas nonfatal suicidal behaviors are more prevalent among women and persons who are young, are unmarried, or have a psychiatric disorder. Despite an increase in the treatment of suicidal persons over the past decade, incidence rates of suicidal behavior have remained largely unchanged. Most epidemiologic research on suicidal behavior has focused on patterns and correlates of prevalence. The next generation of studies must examine synergistic effects among modifiable risk and protective factors. New studies must incorporate recent advances in survey methods and clinical assessment. Results should be used in ongoing efforts to decrease the significant loss of life caused by suicidal behavior.engacceso cerradoarticle1Instituto Nacional de Psiquiatría Ramón de la Fuente Muñiz133-154Cary30NATIONAL COMORBIDITY SURVEYRANDOMIZED CONTROLLED-TRIALSEROTONIN TRANSPORTER GENEHIGH-SCHOOL-STUDENTSTOWER-OF-BABELLONGITUDINAL PERSONALITY-DISORDERSWORLD-HEALTH-ORGANIZATIONNONSUICIDAL SELF-INJURYFEMALE TWIN SAMPLEAXIS-II DISORDERSpsychiatrypublic healthrisk factorsself-injurious behaviorsuicidesuicideattempted
