[Sociodemographic features of suicide attempts]

Suicide accounts for about 10% of deaths among psychiatric patients, and life-threatening attempts are much more common than fatalities. Despite progress in defining risk rates and predictive factors, knowledge on which to base sound clinical and public policies regarding suicide prevention and treatment remains remarkably limited. Social risk factors and psychiatry diagnoses are the main arguments to management the suicidal behaviour in emergency room. Female gender is associate with suicide attempts while male gander is associate with completed suicide. Risk of suicide is increased in young and elderly people. Age is a confounding factor in the relationship among suicide and widow, income and professional status. Emigration and anomie are related with suicide. Social factor, as a marker of suicidal behaviour, are a promising research question.
