Suicidal phenomena and abuse in adolescents: a review of epidemiological studies

Objective: To conduct a systematic review of the international literature to determine whether adolescents who had experienced abuse were more likely to also experience suicidal thoughts and behaviors than other adolescents, and to investigate the nature of this association. Method: Reports of community- or school-based studies of adolescents on the association between the prevalence of suicidal phenomena and abuse were searched for via electronic databases, reviewing reference lists and contacting experts in the field. Results: Ten relevant studies were identified. Adolescents who had been physically or sexually abused were signif-icantly more likely to experience suicidal thoughts and behaviors than other adolescents. This association appeared to be direct in most studies in which multivariate analyses were conducted. There is evidence that other factors (e.g., low self-esteem) may play a mediating role in the relationship between abuse and suicidal phenomena. Conclusions: There is a clear link between abuse and suicidal phenomena occurring during childhood and adoles-cence
