Prevalence and Impact of Severe Mental Illness in the Australian Indigenous Population: A Comprehensive Review
摘要
To investigate the prevalence and impact of severe mental illness (SMI) within the Australian Indigenous population. A systematic search of existing literature and data sources was conducted, using PubMed, Web of Science, EMBASE, MEDLINE, PsycINFO, and SCOPUS, to collect and analyse information on the prevalence of SMI among Indigenous Australians. Screening, data extraction and risk of bias assessments were performed independently by three co-authors. Of the 3372 studies identified by the search strategy, 16 studies met the eligibility criteria and were reviewed in detail. Results indicated that the pooled prevalence of all SMI in health centre or community settings was 2.58% (95% CI 1.37–4.85), bipolar disorder was 0.32% (95% CI 0.01–17.48), schizophrenia was 1.39% (95% CI 0.86–2.25). The pooled prevalence of SMI in incarceration is 12.26% (95% CI 4.29–35.02). Indigenous Australians reported a higher prevalence of SMI than non-Indigenous Australians. Besides, one study showed that the incidence of metabolic syndrome (MetS) in Indigenous Australians with SMI (66%), higher than in non-Indigenous Australians (55%). There is an urgent need to address mental health inequality among the Indigenous Australians and conduct further research in the areas of standardized diagnostic methods, the relationship between SMI and incarceration, and the incidence of MetS.
