Abstract

BackgroundTo describe the prevalence, type, and mental health correlates of substance use disorders in a large sample of incarcerated Indigenous Australians.MethodsAn epidemiological survey of the mental health of Indigenous people in custody in the state of Queensland, Australia was conducted using culturally informed methods. The prevalence, type and mental health correlates of substance use disorders were determined using a diagnostic interview and questionnaire.ResultsIn a sample of 396 Indigenous people (331 males, 65 females) the prevalence of any substance use disorder was 66%. Alcohol dependence (males 47%, females 55%) was the most common type of substance use disorder, followed by cannabis dependence (males 20%, females 26%). Mental illness (anxiety, depression and psychotic disorder), and lifetime suicide thoughts and attempts, were significantly more likely among those with a substance use disorder. The majority of the sample reported intoxication with alcohol (70%) and/or other drugs (51%) at the time of arrest. Most individuals (87%) had not accessed alcohol and other drug services in the 12 months prior to custody.ConclusionsSubstance dependence was common in this sample and was associated with other forms of mental health adversity, yet most individuals reported no access to health services prior to incarceration. Effectively responding to substance dependence for Indigenous Australians is a public health and criminal justice priority. Culturally capable alcohol and other drug treatment services in custody and in the community are critical, and should be co-located and coordinated with mental health services.

Highlights

To describe the prevalence, type, and mental health correlates of substance use disorders in a large sample of incarcerated Indigenous Australians
The age standardised rate of incarceration for Indigenous Australians is 13 times that of non-Indigenous Australians (Australian Bureau of Statistics 2014) and the majority of Indigenous people in custody suffer from mental disorders
The Australian National Mental Health Commission described the high rates of incarceration of Indigenous people as “shocking” (National Mental Health Commission 2013) and noted the relationship with the high prevalence of mental disorder in this group

Summary

Introduction

Type, and mental health correlates of substance use disorders in a large sample of incarcerated Indigenous Australians. The 2015 Australian Medical Association report card on the health Aboriginal and Torres Strait Islander people (Indigenous Australians) described significant concern over the escalation in incarceration rates (Australian Medical Association 2015) The report interpreted this problem as symptomatic of the health disparity between Indigenous and non-Indigenous Australians. The Australian National Mental Health Commission described the high rates of incarceration of Indigenous people as “shocking” (National Mental Health Commission 2013) and noted the relationship with the high prevalence of mental disorder in this group. These concerns were highlighted in a recent annual report that monitors Australia’s progress in addressing the health
