Background and objective: Suicide is a public health problem and it is increasing in Spain. The objective of this study is to analyze the prevalence and risk factors of suicide related outcomes (ideation, plan and attempt) using data from the ESEMeD-Spain project.
Subjects and method: This is a face-to-face household survey carried out in a probability representative sample of the adult general population of Spain. 5,473 subjects were interviewed using the Composite International Diagnostic Interview (CIDI 3.0), developed by the World Mental Health Survey Initiative.
Results: Lifetime prevalence of suicide ideation and attempts was 4.4% and 1.5%, respectively. Risk of suicide related outcomes was significantly higher among women (odds ratio [OR] = 2.3-2.7), younger cohorts (OR = 21.3-86), and lower education levels (OR = 5.3-6.4). Having a mental disorder was associated to an increased risk in all diagnostic categories, but especially in major depressive episode (OR = 5.3-6.8). Risk of suicide attempt was higher during the first year since the onset of ideation (OR = 30.2), decreasing thereafter.
Conclusions: The prevalence of suicide related outcomes is low when compared with other countries. Results identified groups with higher risk (women, young, subjects with a mental disorder, psychiatric comorbidity and recent suicidal ideation) in which suicide prevention could show benefits.
