BACKGROUND:

Suicidal behavior is a public health problem, and adolescents are one of the main risk groups.

Aim:

To analyze the association among suicidal behavior, consumption of psychoactive substances, and Health Related Quality of Life (HRQoL) in adolescents attending schools in Valparaiso, Chile. MATERIAL AND

METHODS:

Five hundred-fifty adolescents enrolled in a public school participated in the study. HRQoL was evaluated through KIDSCREEN-27, while suicidal behavior and the consumption of psychoactive substances were measured with the Global School-based Student Health Survey (GSHS).

RESULTS:

The prevalence of suicidal behavior was higher in women and in those who used tobacco or marijuana in the last month. Respondents with a bad perception of physical well-being reported a higher frequency of suicidal ideation than those with a good perception (Odds ratio (OR) 2.24; 95% confidence 1.49-3.36). Likewise the frequency of suicidal ideation was higher in those with a bad perception of psychological well-being (OR 3.87; 95%CI 2.09-7.71), and a bad perception of autonomy and relation with parents (OR2.46; 95%CI 1.34-4.54). Suicide planning was also associated with dimensions of autonomy and relation with parents (OR 2.32; 95% CI 1.23-4.38) and dimensions of friends and social support (OR 1.86; 95%CI1.05-3.28). Suicide attempt was associated with the dimensions of friendship and social support (OR 1.83; 95%CI 1.02-3.28) and school environment (OR 1,92; 95%CI 1,23-3,01).

Conclusions:

Suicide ideation is associated with worse physical and psychological well-being. Suicide planning and suicide attempt is associated with a worse perception about the relation with parents or friends, social support, and school environment.
