Abstract
OBJECTIVES: To compare demographic and psychosocial characteristics of completed suicide between younger and older adolescents, and by sex. METHODS: Data was collected from the Victorian Suicide Register, which contains information on suicides reported to the Coroners Court of Victoria. RESULTS: Between 2006 and 2015, there were 273 completed suicides aged 10-19 years, with none aged 10-12 years. There were 171 (63%) suicides in the older adolescent group (17-19 years), and 102 (37%) in the younger group (13-16 years). Males comprised 184 cases (67%) and females 89 (33%). A higher proportion of both younger and female adolescents had experienced abuse, peer conflict and bullying. There was also a higher incidence of previous self-harm in younger and female adolescents. Older adolescents were more likely to not be in formal education, employment or training. CONCLUSION: Suicide in younger adolescents and females appear to share characteristics, and differ from older and male adolescents. Negative interpersonal relationships and previous self-harm with possible co-existenting mental illness appear to be key differentiating features. Implications for public health: Understanding completed suicide is an important step towards prevention, and our results suggest a need for developmentally and sex-specific suicide prevention strategies.
