“…22 Similar trends of excess rates of ICH have been described in some other Indigenous populations relative to their respective non-Indigenous populations, though data are sparse. 23 Conversely, incidence rates of SAH appeared similar in the Aboriginal and non-Aboriginal populations, as has been reported in one previous population-based hospital study that included just 6 Aboriginal people with SAH. 19 Small overall numbers of SAH events may have reduced our ability to detect differences in rates.…”

“…Aboriginal and Torres Strait Islander (hereafter respectfully referred to as Aboriginal) peoples experience substantial disparities in health outcomes, compared with non-Aboriginal Australians, strongly influenced by the ongoing health and socioeconomic effects of colonization. 1 Life expectancy is 8 years less than in non-Aboriginal Australians overall, and 14 years less in remote and very remote regions. Cardiovascular disease accounts for the largest gap in death rates between Aboriginal and non-Aboriginal Australians.…”

Background: Most estimates of stroke incidence among Aboriginal and Torres Strait Islander (hereinafter Aboriginal) Australians are confined to single regions and include small sample sizes. We aimed to measure and compare stroke incidence in Aboriginal and non-Aboriginal residents across central and western Australia. Methods: Whole-population multijurisdictional person-linked data from hospital and death datasets were used to identify stroke admissions and stroke-related deaths (2001–2015) in Western Australia, South Australia, and the Northern Territory. Fatal (including out-of-hospital deaths) and nonfatal incident (first-ever) strokes in patients aged 20-84 years were identified during the 4-year study period (2012–2015), using a 10-year lookback period to exclude people with prior stroke. Incidence rates per 100 000 population/year were estimated for Aboriginal and non-Aboriginal populations, age-standardized to the World Health Organization World Standard population. Results: In a population of 3 223 711 people (3.7% Aboriginal), 11 740 incident (first-ever) strokes (20.6% regional/remote location of residence; 15.6% fatal) were identified from 2012 to 2015, 675 (5.7%) in Aboriginal people (73.6% regional/remote; 17.0% fatal). Median age of Aboriginal cases (54.5 years; 50.1% female) was 16 years younger than non-Aboriginal cases (70.3 years; 44.1% female; P <0.001), with significantly greater prevalence of comorbidities. Age-standardized stroke incidence in Aboriginal people (192/100 000 [95% CI, 177–208]) was 2.9-fold greater than in non-Aboriginal people (66/100 000 [95% CI, 65–68]) aged 20-84 years; fatal incidence was 4.2-fold greater (38/100 000 [95% CI, 31–46] versus 9/100 000 [95% CI, 9–10]). Disparities were particularly apparent at younger ages (20–54 years), where age-standardized stroke incidence was 4.3-fold greater in Aboriginal people (90/100 000 [95% CI, 81–100]) than non-Aboriginal people (21/100 000 [95% CI, 20–22]). Conclusions: Stroke occurred more commonly, and at younger ages, in Aboriginal than non-Aboriginal populations. Greater prevalence of baseline comorbidities was present in the younger Aboriginal population. Improved primary prevention is required. To optimize stroke prevention, interventions should include culturally appropriate community-based health promotion and integrated support for nonmetropolitan health services.

“…Complex historical, political, and social factors contribute to health disparities between Aboriginal and other Australians, and these factors influence modifiable cardiovascular risk factors 6,7 . Clarifying which risk factors contribute most to population‐attributable stroke risk would enable more effective primary and secondary prevention 8 .…”

ObjectiveWe performed a pilot stroke incidence study, focused on feasibility and inclusion of the CONSIDER reporting guidelines, to model the design of a future population‐based study aiming to definitively determine stroke incidence, antecedents, treatment, and outcomes.Study designProspective stroke incidence study (pilot study).Setting, participantsAll people aged 15 years or older who lived in postcode‐defined areas of South Australia and Northern Territory (885 472 people, including 45 127 Aboriginal people [5.1%]) diagnosed with stroke for the first time during 1 October – 31 December 2015 and admitted to public hospitals or stroke and transient ischaemic attack clinics.Main outcome measuresFeasibility of a prospective population‐based stroke incidence study.ResultsOf the 123 participants with first strokes, ten were Aboriginal (8%); the median age of Aboriginal people was 45 years (interquartile range [IQR], 33–55 years), of non‐Indigenous people 73 years (IQR, 62–84 years). For Aboriginal people, the age‐standardised incidence of stroke was 104 (95% confidence interval [CI], 84–124) per 100 000 person‐years, for non‐Indigenous people 33 (95% CI, 22–44) per 100 000 person‐years. We found that a prospective population‐based stroke incidence study in Aboriginal people was feasible, including with respect to establishing an adequate sample size, diagnostic confirmation, identification of incident stroke, confirming stroke subtypes, establishing a stable statistical population, standardising data reporting for comparison with other stroke incidence studies, and ethical research reporting that conforms to CONSIDER guidelines.ConclusionsA larger, population‐based study of the incidence of stroke in Aboriginal people is both feasible and needed to provide robust estimates of stroke incidence, antecedents, treatments and outcomes to help guide strategies for reducing the risk of and outcomes of stroke in Aboriginal people.
