Risk and Protective Factors for Suicide Mortality in Youths

What factors are associated with risk of suicide mortality among individuals aged 24 years and younger?In this systematic review and meta-analysis of 90 reports (68 reports), mental disorders—particularly acute conditions such as schizophrenia and mood disorders—and prior self-harm were associated with suicide mortality. Prior health care contact (eg, psychiatric admission) and a range of social determinants (eg, maltreatment, out-of-home placement, and social disadvantage) were also associated with higher risk, whereas family stability (eg, living with both parents) was associated with lower risk.Suicide mortality in youths reflects both psychiatric vulnerability and social adversity, supporting the need for integrated prevention strategies combining early intervention with population-level prevention approaches targeting social determinants.
