Suicides in Aboriginal and Torres Strait Islander children: analysis of Queensland Suicide Register

To provide an overview of the mental health of Aboriginal and Torres Strait Islander residents of rural and remote Australia and to identify associated factors. Indigenous Australians have higher rates of serious mental disorders and of mental health problems associated with social disadvantage. This disadvantage is greater for Indigenous Australians living outside metropolitan centres. Contrary to romanticised constructions of remote Aboriginal Australia, those living in such settings are not immune to such hardship - which is often unrelenting. The psychological and behavioural problems that emerge as a result are compounded by narrowly focused and inadequate mental health services, with children being particularly vulnerable. Indigenous residents of rural and remote Australia experience high levels of mental disorder. Although addressing the predisposing social disadvantage will demand significant whole-of-government investment, ensuring equitable access to effective mental health services is an immediate priority.

Suicide in children and young adolescents up to 14 years of age has increased in many countries, warranting research and clinical awareness. International reported suicide rates per 100,000 in this young population vary between 3.1 and 0 (mean rate worldwide, approximately 0.6/100.000; male-female ratio, 2:1). Suicide occurs only in vulnerable children; this vulnerability begins with parental mood disorder and impulsive aggression, and family history of suicide. Childhood affective and disruptive disorders and abuse are the most often reported psychiatric risk factors. Suicide becomes increasingly common after puberty, most probably because of pubertal onset of depression and substance abuse, which substantially aggravate suicide risk. Biologic findings are scarce; however, serotonergic dysfunction is assumed. The most common precipitants are school and family problems and may include actual/anticipated transitions in these environments. Suicides in children and young adolescents up to 14 years of age often follow a brief period of stress. Cognitive immaturity/misjudgment, age-related impulsivity, and availability of suicide methods play an important role. Psychologic autopsy studies that focus on suicides in this age group are needed.
