To compare demographic and psychosocial characteristics of completed suicide between younger and older adolescents, and by sex.
Data was collected from the Victorian Suicide Register, which contains information on suicides reported to the Coroners Court of Victoria.
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.
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.
比较青少年和老年人完成自杀的人口统计学和社会心理特征，并按性别进行比较。
数据来自维多利亚州自杀登记处，其中包含向维多利亚州验尸官法庭报告的自杀事件信息。
在 2006 年至 2015 年间，有 273 例 10-19 岁的青少年完成自杀，没有 10-12 岁的自杀案例。17-19 岁的青少年中，有 171 例（63%）自杀，13-16 岁的青少年中有 102 例（37%）。男性占 184 例（67%），女性占 89 例（33%）。无论是青少年还是女性，经历过虐待、同伴冲突和欺凌的比例都较高。青少年和女性自杀前有过更多的自残行为。年长的青少年更有可能没有接受正规教育、就业或培训。
青少年和女性的自杀似乎有一些共同的特征，与年长和男性青少年有所不同。负面的人际关系和之前可能存在的精神疾病的自残行为似乎是关键的区别特征。对公共卫生的启示：了解完成自杀是预防的重要一步，我们的结果表明需要制定针对特定年龄段和性别的自杀预防策略。
