Abstract
Close to one million people commit suicide each year, with suicidal attempts being the main risk factor for suicide. The aim of this systematic review and meta-analysis is to achieve a greater understanding of suicidality in the general population of Europe by studying associated factors and their statistical significance with suicidality, as well as the effect of the temporal moment in which suicidality is observed in a relationship. A search strategy was carried out in electronic databases: Proquest’s Psychology Database, Scopus, PsycINFO, Medline and Embase. Odds ratios (ORs), publication bias, influential studies on heterogeneity and analysis moderators were calculated. Twenty-six studies were included after meeting the inclusion criteria. Factors statistically associated with suicidality are female gender, age over 65 years, unemployment, low social support, adulthood adversity, childhood adversity, family history of mental disorder, any affective disorder, major depression, anxiety/stress/somatoform disorders, tobacco and substance use, any mental disorder and body mass index. As a limitation, a high heterogeneity between studies was found. Factors associated with suicidality in the general population are relevant for understanding the suicidal phenomenon.Systematic review registration: PROSPERO (CRD42017075190).
Highlights
Every year, close to one million people commit suicide, affecting the contexts they belonged to and survivors [1]
It was found that several factors studied are related to suicidality, that these relationships vary depending on the type of suicidality and that there are effects of the moderator period of time
We suggest that future research on suicidality should focus on factors that may be important for specific regions and cultural contexts
Summary
Close to one million people commit suicide, affecting the contexts they belonged to and survivors [1]. Suicide attempts are the main risk factor for suicide For this reason, the study of suicidality is especially relevant, as their prevention decreases the risk of a completed suicide. To understand the differences between the behaviors included in suicidality, the distinction established by Nock and Favazza [3] is useful. These authors define suicidal ideation as “thoughts of engaging in behaviors intended to end one’s own life”. In this way, they differ from death wishes, which are characterized by being passive
