Abstract
Suicide mortality rates are increasing among teenagers. To study the prevalence and predictive factors of suicide attempts among Chilean adolescents. A random sample of 195 teenagers aged 16 ± 1 years (53% males) answered an anonymous survey about their demographic features, substance abuse, the Osaka suicidal ideation questionnaire, Smilksten familial Apgar. Beck hopelessness scale, Beck depression scale and Coppersmith self-esteem inventory. Twenty five percent of respondents had attempted suicide at least in one occasion during their lives. These attempts were significantly associated with female gender, absent parents, family dysfunction, drug abuse, smoking, low self-esteem, hopelessness, depression and recent suicidal ideation. A logistic regression analysis accepted female gender, smoking and recent suicidal ideation as significant independent predictors of suicide attempt. Suicide attempted is common among teenagers and its predictors are female sex, smoking and previous suicidal ideation.

Summary
Suicide mortality rates are increasing among teenagers. Aim: To study the prevalence and predictive factors of suicide attempts among Chilean adolescents. Results: Twenty five percent of respondents had attempted suicide at least in one occasion during their lives These attempts were significantly associated with female gender, absent parents, family dysfunction, drug abuse, smoking, low self-esteem, hopelessness, depression and recent suicidal ideation. Ya que el intento de suicidio es uno de los principales predictores de suicidio consumado[5], resulta especialmente importante conocer su prevalencia y factores de riesgo asociados en población general y, particularmente, en adolescentes. De esta forma, el estudio planteado aporta un nuevo ángulo de análisis al efectuarse en una muestra representativa de estudiantes del único establecimiento secundario de Santa Juana, una comuna de 12.700 habitantes con una alta proporción de ruralidad (44,19% de población rural) y un importante componente de estudiantes que no residen en casa durante el año escolar, e incorporar la ideación suicida como posible factor determinante. Establecer un modelo de regresión logística multivariada que permita determinar el impacto de las distintas variables en la presencia de intento de suicidio a lo largo de la vida
