Factors Associated with Suicidal Behavior in Adolescents: An Umbrella Review Using the Socio-Ecological Model

Adolescent suicide is a critical social issue with profound and lasting individual and collective consequences. This umbrella review examines factors associated with adolescent suicidal behavior through the socioecological framework of prevention and seeks to identify gaps in the existing literature. The review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and included a comprehensive search of the of the Web of Science, Scopus, and Cochrane databases in both English and Spanish, covering the period from 2018 to 2024, using terms related to adolescence and suicidal behavior. Out of 6,138 articles identified, 37 met the quality criteria and were selected for analysis. The studies highlighted individual risk factors such as age, gender, belonging to ethnic or gender minorities, emotional disorders, self-destructive behavior, emotional regulation, and experience of physical or emotional pain. Interpersonal factors such as parental relationships, sexual abuse, social isolation, peer pressure, and loneliness were also found. However, the review revealed a worrying lack of studies on societal and community factors and a paucity of research focusing on protective factors. The study highlights the need to include factors related to the physical and social environments that influence health and behavior in future research, as well as to enhance the resources and strengths of adolescents.
