Hepatitis C care cascade before and during the direct-acting antiviral eras in New South Wales, Australia: A population-based linkage study.

The hepatitis C virus (HCV) care cascade characterization is important for monitoring progress towards HCV elimination. This study evaluated HCV care cascade and factors associated with treatment during pre-DAA (2011-2012 and 2013-2015) and DAA (2016-2018) eras in New South Wales (NSW), Australia. We conducted a cohort study of people with an HCV notification (1993 to 2017) through end 2018, linked to administrative datasets, including HCV treatment and non-hospital services. Those aged <18 years, died within first 6 months of study period or notification, and who had successful HCV treatment in period before were excluded. Sex-specific spontaneous viral clearance was incorporated to estimate treatment-eligible population. The study population in each period were cumulative and brought forward from one period to the next. Among 115,667 people with HCV notification, 87,063 fulfilled eligibility criteria. During 2011 to 2012, 2013 to 2015, and 2016 to 2018, cumulative HCV notifications were 71,677, 77,969, and 80,017; 52,016, 56,793, and 57,467 were eligible for treatment; 29%, 48%, and 64% confirmed HCV RNA positive; and 0.6%, 5%, and 38% initiated HCV treatment, respectively. Birth cohort 1945 to 1964 (vs. ≥1965), males, non-Aboriginal ethnicity, regional/rural area of residence, and HCV/HIV co-infection were associated with higher treatment uptake. Incarceration and drug dependence were associated with higher treatment uptake during the DAA era. In Australia, many marginalized populations including those incarcerated and those with drug dependence have equitable treatment uptake in the DAA era. Targeted strategies are required to enhance treatment uptake for females and Aboriginal populations.

Ficoline-3 and MASP-2 gene variants in siberian arctic populations: SUMMARIZED Evidence of selective pressure for the high frequency of lectin complement pathway deficiency.

A total of 926 specimens of dried blood spots of the newborns were genotyped. The newborns represented four populations: Nenets, Dolgan-Nganasans, Mixed aboriginal population, and Russians (Caucasians) to study the prevalence of single nucleotide polymorphisms of FCN3 rs532781899 and MASP2 rs72550870. The prevalence of the deletion allele of the rs532781899 variant in the FCN3 gene associated with the decreased production of ficoline-3 was found to be increased in Russians compared to the Nenets aboriginal populations (p=0.002). The prevalence of the rs72550870*G allele in the MASP2 gene associated with low serum protease activity was found to be increased in Russians compared with Nenets and Dolgan-Nganasans (p < 0.001 and p=0.03, respectively). The results of the current study and our previous findings corroborate with a hypothesis that human evolution has been directed toward the accumulation of genotypes associated with low activity of the lectin complement activation pathway.

Is the evidence-based medicine movement counter-productive: are randomised controlled trials the best approach to establish evidence in complex healthcare situations?

In the modern era, evidence-based medicine (EBM) has been embraced as the best approach to practising medicine, providing clinicians with 'objective' evidence from clinical research. However, for presentations with complex pathophysiology or from complex social environments, sometimes there remains no evidence, and no amount of research will obtain it. Yet, health researchers continue to undertake randomised controlled trials (RCT) in complex environments, ignoring the risk that participants' health may be compromised throughout the trial process. This paper examines the role of research that seeks to obtain evidence to support EBM. We provide examples of RCTs on ear disease in Aboriginal populations as a case-in-point. Decades of ear research have failed to yield statistically significant findings, demonstrating that when multiple factors are at play, study designs struggle to balance the known disease process drivers, let alone unknown drivers. This paper asks the reader to consider if the pursuit of research is likely to produce evidence in complex situations; or if perhaps RCTs should not be undertaken in these situations. Instead, clinicians could apply empirical evidence, tailoring treatments to individuals while taking into account the complexities of their life circumstances.

External validation of the Health Care Homes hospital admission risk stratification tool in the Aboriginal Australian population of the Northern Territory.

ObjectiveThis study aimed to externally validate the Commonwealth's Health Care Homes (HCH) algorithm for Aboriginal Australians living in the Northern Territory (NT).MethodsA retrospective cohort study design using linked primary health care (PHC) and hospital data was used to analyse the performance of the HCH algorithm in predicting the risk of hospitalisation for the NT study population. The study population consisted of Aboriginal Australians residing in the NT who have visited a PHC clinic at one of the 54 NT Government clinics at least once between 1 January 2013 and 31 December 2017. Predictors of hospitalisation included demographics, patient observations, medications, diagnoses, pathology results and previous hospitalisation.ResultsThere were a total of 3256 (28.5%) emergency attendances or preventable hospitalisations during the study period. The HCH algorithm had an area under the receiver operating characteristic curve (AUC) of 0.58 for the NT remote Aboriginal population, compared with 0.66 in the Victorian cohort. A refitted model including 'previous hospitalisation' had an AUC of 0.72, demonstrating better discrimination than the HCH algorithm. Calibration was also improved in the refitted model, with an intercept of 0.00 and a slope of 1.00, compared with an intercept of 1.29 and a slope of 0.55 in the HCH algorithm.ConclusionThe HCH algorithm performed poorly on the NT cohort compared with the Victorian cohort, due to differences in population demographics and burden of disease. A population-specific hospitalisation risk algorithm is required for the NT.

The availability and delivery of culturally responsive Australian Aboriginal infant resuscitation education programmes: a structured literature review.

To critically appraise the literature to determine availability and identify the cultural responsiveness of infant resuscitation education for Aboriginal and Torres Strait Islander populations. Despite overall reductions in infant mortality in the last two decades, Aboriginal people have some of the highest rates of infant mortality of any developed nation. One of the key factors that has attributed to improvements in infant mortality rates is parent and carer education around risk factors and actions of first responders. Identifying gaps in the current basic first-aid initiatives available to Aboriginal communities may contribute to developing resources to contribute to reductions in Aboriginal neonatal mortality rates. The review used key terms and Boolean operators across an 11-month time frame searching for research articles utilising the databases of CINAHL, Scopus, Ovid Emcare, Informit, Pubmed and Proquest. After review, 39 articles met the inclusion criteria, 25 articles were discarded due to irrelevant material and 14 articles were included in the structured literature review. The search process was developed using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. Articles were assessed for validity and inclusion using the Critical Appraisal Skills Program checklist. Research literature relating to First Nation community-based CPR and first-aid education programmes in Canada, USA, India, UK and Europe, Asia and Africa were identified; however, none pertaining specifically to CPR and first-aid education in Australian Aboriginal communities were found. Despite the lack of research evidence relating to infant cardiopulmonary resuscitation (CPR) education for Australian Aboriginal populations, the reviewed studies noted the importance of culturally responsive education designed in collaboration with First Nation peoples, using novel ways of teaching CPR, that align with the language, culture and needs of the communities it is intended for. Further research is required to create a framework for the delivery of culturally responsive infant resuscitation education for Australian Aboriginal parents and communities.

Review of the health impact of the oral rotavirus vaccine program in children under 5years in Australia: 2006 - 2021.

Oral rotavirus vaccines were incorporated into the National Immunisation Program (NIP) for all Australian infants in July 2007. Initially each of the eight jurisdictions implemented Rotarix or RotaTeq rotavirus vaccine, however from July 2017 all states and territories have administered Rotarix only. This review evaluates the health impact of the oral rotavirus vaccine program for Australian children less than 5years old over the first 15years of the rotavirus vaccine program, observing long-term changes in rotavirus-related health care attendances, public health notifications, and vaccine effectiveness and safety data for both Rotarix and RotaTeq rotavirus vaccines. We searched Medline for studies published between January 2006 and May 2022 using the search terms 'rotavirus', 'rotavirus vaccine' and 'Australia'. Of 491 items identified, 76 items - 36 peer-reviewed articles and 40 reports - were included in the review. We found evidence that the introduction of the oral rotavirus vaccine program in Australia was associated with a prompt reduction in rotavirus-coded and all-cause gastroenteritis hospitalisations of vaccine-eligible children. In the context of less complete coverage, reduced vaccine timeliness and lower vaccine effectiveness, a less substantial and inconsistent reduction in severe rotavirus disease was observed among Aboriginal and Torres Strait Islander children, particularly those living in rural and remote northern Australia. Additional studies report no evidence for the emergence of non-vaccine serotypes and/ or replacement serotypes in Australia during the vaccine era. While the health impact for young children and consequent cost-savings of the oral rotavirus vaccine program have been high, it is important to find strategies to improve rotavirus vaccine impact for Aboriginal and Torres Strait Islander populations to ensure health benefits for all Australian children.

What Works for Aboriginal and Torres Strait Islander Men? A Systematic Review of the Literature

Aboriginal and Torres Strait Islander men experience significantly higher rates of suicide, trauma, alcohol related deaths and unemployment than other Australian men. Despite significant levels of government intervention, rates of family violence, unemployment and incarceration continue to increase in Aboriginal and Torres Strait Islander communities. As a subset of the Aboriginal and Torres Strait Islander population, there has been a lesser focus on how to meaningfully improve the wellbeing of Aboriginal and Torres Strait Islander men. This systematic review seeks to understand what interventions, programs and activities are successful in improving the wellbeing of Aboriginal and Torres Strait Islander men and thereby the wellbeing of their communities. A thorough search of the literature was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Fifteen studies met the inclusion criteria. Analysis of the programs, activities and interventions evaluated in these studies indicated two prominent themes that were successful in improving the wellbeing of Aboriginal and Torres Strait Islander men: strengthening identity and increasing social connection. The mechanisms contributing to these outcomes are discussed, as are implications for policy and future research.

РЕЦЕНЗИЯ НА КНИГУ: Берег Маклая в дневниках и записках этнографов / отв. ред. А. В. Туторский – СПб.: Алетейя, 2021 – 358 с

The review discusses a collection of field diaries and notes of naturalists and ethnographers-oceanists, which were published in Russian for the first time. The book was compiled by a large team of scientists and translators under the editorship of A. V. Tutorsky, Candidate of Historical Sciences. After reading the collection, the interested reader will learn a lot of specific historical data about the aboriginal population of the Maclay Coast from the late 19th to the early 21st centuries. The book should serve to demystify and falsely romanticize the region, which is still exploited by travel agencies around the world.

Digging into the admixture strata of current-day Canary Islanders based on mitogenomes

The conquest of the Canary Islands by Europeans began at the beginning of the 15th century and culminated in 1496 with the surrender of the aborigines. The collapse of the aboriginal population during the conquest and the arrival of settlers caused a drastic change in the demographic composition of the archipelago. To shed light on this historical process, we analyzed 896 mitogenomes of current inhabitants from the seven main islands. Our findings confirm the continuity of aboriginal maternal contributions and the persistence of their genetic footprints in the current population, even at higher levels (>60% on average) than previously evidenced. Moreover, the age estimates for most autochthonous founder lineages support a first aboriginal arrival to the islands at the beginning of the first millennium. We also revealed for the first time that the main recognizable genetic influences from Europe are from Portuguese and Galicians.

Assessment equity for remote multilingual Australian Aboriginal students through the lens of Sustainable Development Goals

Purpose The Foundations of Early Literacy Assessment – Northern Territory (FELA-NT) was funded, developed, and implemented as part of a strategy designed to address the English literacy learning needs of the Northern Territory’s Aboriginal student population. In this paper we question whether the FELA-NT English literacy learning benchmarks are representative of remote and very remote Aboriginal students since many speak English as an Additional Language (EAL) or Dialect (EAD). Result Using a new data set of scores from 72 Aboriginal students from remote, very remote, and outer-regional communities on the FELA-NT, we demonstrate that it is the student’s experience with Standard Australian English, not their remoteness, that impacts their early literacy development. Conclusion We use this example to illustrate how current practices and policies homogenise the Australian Aboriginal student population, silencing linguistic diversity in the process. We call for clinical practitioners and educators to shift their practices to assessments and tools that recognise children and youths’ diverse linguistic skills and pathways. We talk about what empowerment, participation, and inclusion might really mean in current Australian educational and clinical contexts. We argue here that we need to fundamentally rethink how we work with children with diverse language and literacy knowledge, skills, and backgrounds if we are to reduce inequalities (SDG 10), honour quality education (SDG 4), and support sustainable communities (SDG 11).

Ethnic Cleansing of the XVth–XVIIth Centuries in Eastern Ukraine Territories (On the Issue of Sources of Rashist Praxis)

The article deals with how Muscovy, in the XVth – early to mid-XVIIth centuries, changed the ethnic composition of the Siverian Lands and the Upper Oka Principalities – the then eastern territories of Rus-Ukraine – due to large-scale ethnic cleansing and their subsequent settlement by Muscovites. It is shown how, in the course of expansionist practices at the dawn of the Russian Empire formation, modern methods of hybrid war arose, with its propaganda, seizure of territories, looting, extermination and deportation of people. There is an analysis of the insufficiently researched events of the late XVth to early XVIIth centuries in eastern Rus-Ukraine, in the Siverian Lands and on its eastern border – in the Upper Oka Principalities. These territories, which, along with other Ukrainian lands, previously belonged to the Grand Duchy of Lithuania and were occupied by Muscovy in the course of two wars, were inhabited by Sevryuks and minor communities – Mtsenskians, Lyubuchans, Kozelskians and others. The article’s task is to trace the rhetoric of Moscow’s ruling circles with regard to substantiating the imperial expansion, as well as to study actions of the conquerors from the point of view of identifying their ethnic component, including ethnic cleansing carried out by them. Sources of the study are ambassadorial documents, chronicles, memoirs and diaries of foreigners. Methodology of this historical and anthropological investigation includes achievements of scholars in studying ethnocentric conceptions (Justin Stagl, Anthony Smith, Oleksiy Tolochko) and the behavior of war people in pre-modern times (Philippe Contamine, Natalia Yakovenko). Result. During Muscovite-Lithuanian wars, with the first of which (1486–1494) undeclared, Moscow, for justifying its actions, widely used extensively deception and information sabotage (accusations of intimidating Orthodoxy, etc.), statements about the alleged patrimonial right to the former Ancient Rus lands. Emphasis is placed on the relationship between the conquerors and the local population, in which the own-alien contraposition is displayed. Attention is drawn to the cruel, even for the Middle Ages, Muscovite practices in relation to aborigines: looting, terror, murders, taking prisoners, and even enticement of local princes to their side, annexation and colonization of lands. During the second war (1500–1503), only the lands of the princes, whom Moscow lured to its side by lavish promises and deception, escaped plunder. After the annexation of Sivershchyna, Muscovites started to populate these territories on a mass scale, which, along with the oppression of autochthons, caused dissatisfaction among the latter. Attention is also drawn to the peculiar separatism of Sevryuks, who, during the Time of Troubles in Muscovy in the early XVIIth century, have given support to False Dmitrys, chieftain Bolotnikov and other impostors. To this, Moscow authorities responded with brutal terror, in the course of which the rebels were dealt with in the most terrible way. It resulted in devastation of Sivershchyna, while the remains of aboriginal population were assimilated. Conclusion. The comparison between Russia’s expansionist practices of today and five-to-three hundred years ago, including the great-power demagogy of Russian rulers, as justification for conquest, as well as the predatory behavior of Russian subjects, demonstrates a significant similarity. This indicates that the emergence of the current ideology of Rashism and Rashist practices goes back to old times, when the future Russian Empire just began to come into being.

Current state and prospects of breeding of the askaniya population of the gray Ukrainian cattle breed

Preservation of aboriginal breeds and populations of domestic animals is one of the main tasks set before the world community by the Convention on Biological Diversity. With the intensification of Ukrainian livestock breeding with the use of commercial imported breeds, there is a threat of loss of domestic unique gene pools that carry original sets of alleles responsible for high adaptability and resistance to environmental factors in combination with high productivity and reproduction. The article assesses the current state of the Askania gray Ukrainian breed population and the dynamics of its development based on the results of an expedition survey. Indicators of productivity and reproduction based on the results of the last valuation, dynamics of indicators of productivity and reproduction during 11 years for the period 2010-2020, genealogical structure and structure according to the degree of kinship were studied. The progressive development of the Askani population of the gray Ukrainian breed is determined, which is characterized by a probable increase in live weight, the intensity of growth of young, an increase in the intensity of reproduction and the efficiency of fertility with a decrease in the variability of indicators.&#x0D; The level of adaptability of the herd is high, which allows the animals to sustainably maintain the achieved phenotypic level, responding to the pressure of the external environment with insignificant annual deviations from the average herd. The high record indicators of live weight and growth of young animals revealed during the research put the Askani population of the gray Ukrainian breed at the level of world commercial meat breeds, such as Limousin, Hereford, Aberdeen Angus, light Aquitaine.&#x0D; The Askani population of the gray Ukrainian breed represents a highly valuable gene pool, promising for breeding in extreme climatic conditions, which must be distributed in different regions of Ukraine, increasing the number and area of breeding.

Challenges and opportunities in providing dementia care for Aboriginal and Torres Strait Islander peoples living in rural and remote areas.

Dementia rates within Australian Aboriginal and Torres Strait Islander populations are estimated to be three to five times higher than non-Indigenous populations. Geographical and cultural barriers demand creative ways of delivering culturally appropriate effective dementia care. Focus groups and interviews with people (N = 73) from three Aboriginal Medical Services and communities explored attitudes toward, and experiences of dementia care and services. A thematic analysis highlighted the juxtaposition between biomedical and culturally appropriate models of dementia care. Services at the cultural interface can be adapted to facilitate appropriate dementia care at a local level allowing people to stay on Country, supported by people within one's own Community.

Psychological Network of Stress, Coping and Social Support in an Aboriginal Population.

Over the past decades, increasing research interest has been directed towards the psychosocial factors that impact Aboriginal health, including stress, coping and social support. However, there has been no study that examined whether the behaviours, cognitions and emotions related to stress, coping and social support constitute a psychological network in an Aboriginal population and that examined its properties. To address this gap, the current study employed a new methodology, network psychometrics, to evaluate stress, coping and social support in an Aboriginal Australian population. This study conducted a secondary analysis of the South Australian Aboriginal Birth Cohort (SAABC) study, a randomised controlled trial in South Australia, which included 367 pregnant Aboriginal women at study baseline. The Gaussian Graphical Model was estimated with least absolute shrinkage and selection operator (LASSO). Node centrality was evaluated with eigencentrality, strength and bridge centrality. Network communities were investigated with the walktrap algorithm. The findings indicated that stress, coping and social support constituted a connected psychological network in an Aboriginal population. Furthermore, at the centre of the network were the troubles experienced by the Aboriginal pregnant women, bridging their perceptions of stress and coping and constituting a potential target for future interventions.

The development and validation of a family functioning measure for Aboriginal and Torres Strait Islander adults

BackgroundFamily and kinship networks are a key aspect of culture for Aboriginal and Torres Strait Islander peoples from Australia. They are intrinsically connected to good health and wellbeing, and cultural knowledge exchange. However, despite the known importance of family and kinship networks in Aboriginal and Torres Strait Islander cultures, and the move towards family-centred approaches in healthcare service provision, there is no validated, national measure of family functioning for Aboriginal and Torres Strait Islander peoples. A valid tool to measure family functioning is necessary in order to better understand what fosters good family functioning, and to inform and develop programs and healthcare interventions.MethodsMayi Kuwayu: the National Study of Aboriginal and Torres Strait Islander Wellbeing is a longitudinal cohort study of Aboriginal and Torres Strait Islander adults aged 16 years and over. An existing family functioning scale was modified for use in the Mayi Kuwayu Study to measure family functioning at the national Aboriginal and Torres Strait Islander population level. This study used a national sample of Aboriginal and Torres Strait Islander adults (N = 8705, ≥16 years) for the psychometric assessment of the modified Mayi Kuwayu Study Family Functioning Measure. This involved face validity, acceptability, internal consistency/reliability, construct validity, and convergent and divergent validity testing.ResultsParticipants in this study were 8705 Aboriginal and Torres Strait Islander peoples, with a mean age of 48 years, who primarily live in regional Australia (47.3%). The Mayi Kuwayu Family Functioning Measure demonstrated face validity for family functioning and had good internal consistency/reliability (Cronbach’s alpha > 0.90). Construct validity results were mixed, with an indication of uni-dimensionality (with one component explaining 59.5% of variance), but some item redundancy and inconsistency in responding patterns among groups of respondents. Balancing psychometric properties with Aboriginal and Torres Strait Islander expert and end-user feedback of the measure indicate that the full scale should be retained. Finally, the measure demonstrated strong convergent and divergent validity, with prevalence ratios exhibiting dose-response relationships between family functioning and conceptually related outcomes (convergent validity) and conceptually unrelated outcomes (divergent validity).ConclusionThe Mayi Kuwayu Family Functioning Measure is a valid measure of family functioning in the Aboriginal and Torres Strait Islander adult population.

Inequities in ambient fine particulate matter: A spatiotemporal analysis in Canadian communities

BackgroundExposure to fine particulate matter (PM2.5) is associated with adverse health outcomes but communities are not randomly exposed to PM2.5. Previous cross-sectional environmental injustice analyses in Canada found disproportionately higher exposure to PM2.5 in low-income populations, visible minorities and immigrants. Beyond static surveillance, it is also important to evaluate how changes in PM2.5 exposure over time may differentially impact disadvantaged communities. We examine whether communities with different sociodemographic characteristics benefited equitably from the overall decreases in ambient concentrations of PM2.5 from 2001 to 2016 in Canada. MethodsWe derived census tract level estimates of average annual PM2.5 using validated satellite-based estimations of annual average PM2.5 concentration surfaces. We investigated how the spatial distribution of PM2.5 has evolved over 15 years (2001–2016) by comparing absolute values and rank percentiles of census tract level annual average PM2.5 concentrations in 2001 and 2016. Using decennial census data and multivariable linear regression, we determined if sociodemographic characteristics are associated with changes in exposure to PM2.5, accounting for geographic boundary changes between census periods. ResultsOverall, ambient PM2.5 concentrations decreased from 2001 (median of 9.1 μg/m3) to 2016 (median of 6.4 μg/m3), with varying provincial patterns. Across communities, ranked census tract specific PM2.5 in 2001 and in 2016 are highly correlated (Spearman's rho = 0.75). We found that, on average and accounting for provincial differences and baseline PM2.5, communities with greater density of aboriginal population, lower education, higher shelter-cost-to-income ratio, unemployment or lower income experienced smaller absolute decreases in PM2.5 from 2001 to 2016. ConclusionsIdentifying sociodemographic groups that benefit least from decreasing exposure to PM2.5 highlights the need to consider environmental injustice when designing or revising air pollution policies.

The Representations of Rural Population of the Region in the Reports of Siberian Governor-Generals in the 2&lt;sup&gt;nd&lt;/sup&gt; Half of the 19&lt;sup&gt;th&lt;/sup&gt; Century: “Foreigners”

This article aims to identify the representations of “foreign” people (inorodtsev) of Siberia in the reports of the local governors-general, to define the context of their actualization, to find the mutual relations between the official position of the regional authorities towards the socio-cultural characteristics of the indigenous population, its economic situation and legal status, its relations with Russians and the narratives of the “foreigners’ issue” in Russian periodicals. The study is based on the reports of governors-general of Western and Eastern Siberia from the early 1850s until the abolition of the offices of the West Siberian (1882) and East Siberian governors-general (1887), as well as the Irkutsk governor-general in 1887–1899. Analyzing the above-mentioned sources, the authors take into account that such materials were usually complied with some involvement of predecessors, lower-level officials, invited experts. Comparison of the representations of the “foreign” people in the reports of the governors-general with those reflected in the periodicals shows their similarities and differences. The authors of the reports and many publicists share paternalistic discourse concerning the indigenous population of Siberia and consider the “foreign” people as an object of care and protection. Both of them claim the necessity to reduce the yasak payments, highlight the detrimental influence of merchants, as well as exiles, convicted of criminal and administrative offenses. Remarkably, the reports contain no criticism of the authorities for the decline of the aboriginal population and financial difficulties of the “foreigners”; discuss the problem of the “extinction” of aborigines in quite a soft tone. According to these documents, there was a general tendency in government policy to equalize the legal, social and economic status of “foreigners” with the Russian peasantry. However, at the same time, the governors-general who better knew the Siberian realities – at least some of them – more often defended the interests of the region, and hence the Siberian people, including the indigenous population.

Self-efficacy and oral health outcomes in a regional Australian Aboriginal population

BackgroundPerceived self-efficacy has been associated with psychological well-being, health behaviours and health outcomes. Little is known about the influence of self-efficacy on oral health outcomes for Aboriginal adults in Australia, a population experiencing high levels of oral health conditions. This study examines associations between oral health-related self-efficacy and oral health outcomes in a regional Aboriginal Australian population and investigates whether the associations persist after adjusting for sociodemographic characteristics and other general and oral health-related psychosocial factors.MethodsCross-sectional data were obtained from the baseline questionnaire of the Indigenous Oral Heath Literacy Project, South Australia. Oral health-related self-efficacy was measured using a six item scale, with total sum scores dichotomised into high/low self-efficacy. Oral health outcomes included self-rated oral health and oral health impacts, measured using the Oral Health Impact Profile (OHIP-14). Generalized linear models with a log-Poisson link function were used to estimate Prevalence Ratios (PR) of poor self-rated oral health according to levels of oral health-related self-efficacy. Multivariable linear regressions were used to estimate the association between oral health-related self-efficacy and OHIP-14 scores. Blocks of confounders were subsequently added into the models, with the final model including all factors.ResultsComplete data were available for 252 participants (63%) aged 18 to 82 years (mean age of 37.6 years). Oral health-related self-efficacy was associated with poor self-rated oral health, with a 43% (PR = 1.43 (95% CI 1.09, 1.88)) greater prevalence of poor self-rated oral health among those with low self-efficacy. Oral health-related self-efficacy was associated with OHIP-14 severity scores, with a score over six points higher for those with low self-efficacy (B = 6.27 95% CI 2.71, 9.83). Although addition of perceived stress into the models attenuated the relationship, associations remained in the final models.ConclusionLower levels of oral health-related self-efficacy were associated with a higher prevalence of poor self-rated oral health and greater impacts of oral health among Aboriginal adults in regional South Australia. These associations persisted after controlling for sociodemographic and psychosocial confounders, suggesting that increasing self-efficacy may provide an opportunity for improving oral health outcomes for Aboriginal adults.

Zoonoses and the Aboriginal and Torres Strait Islander population: A One Health scoping review.

With limited access to animal health services, and high disease burdens among domesticated animals, Aboriginal and Torres Strait Islander communities in Australia face higher risk of disease including zoonoses. However, we lack understanding of the contribution of often preventable zoonoses to the health of these communities, which would enable us to enhance public health strategies and improve health outcomes. We conducted a scoping review to identify the current state of evidence on zoonoses in the Aboriginal and Torres Strait Islander population. We examined the size, scope and characteristics of the evidence base and analysed the zoonoses detected in the studies within a One Health framework. We identified 18 studies that detected 22 zoonotic pathogens in animals, people, and the environment, with most studies detecting pathogens in a single One Health sector and no studies investigating pathogens in all three sectors. Findings indicate that despite the strong conceptual foundations of One Health throughout the evidence base, evidence is lacking in application of this concept. There is a need to undertake further research that prioritises Aboriginal and Torres Strait Islander leadership, considers the contribution of human, animal and environmental health factors, and investigates the prevalence and impact of zoonoses in communities through a One Health approach.

Postcolonial churn and the impact of the criminal justice system on Aboriginal people in Western Australia, 1829–2020

This article analyses how the criminalisation and imprisonment of Aboriginal people operated as tools of colonisation in Western Australia (WA) in the nineteenth century, and how this shaped the postcolonial criminal justice system. The racialised double standard embedded in the colonial foundations of state institutions, including the criminal justice system, rippled across generations of Aboriginal people: a reiterative and disruptive process that we dub the ‘postcolonial churn’. This term, adapted from the ‘carceral churn’, describes the destabilising mobilisations embedded in carceral and settler-colonial logics over the long term. It uses data from archival prison registers (Rottnest Island 1838–1931 and Roebourne Prison 1908–1961), as well as historic court, police and newspaper data to map the use of the criminal code in protecting and expanding colonial property rights in the original waves of settler-colonisation. WA is an outlier among the Australian colonies: it was the largest in terms of size (2,642,753 km2), the last colony to receive European convicts (1850–1868), and the last to be awarded self-government (1890). This created a situation where the British government dictated policy for legal forms of subjugation of Aboriginal people at the frontier (first for resisting pastoral industry, later as workers in it) which butted up against localised extra-legal violence by police and settlers. We can trace this dichotomy between policy and practice in the development of surveillance and policing of Aboriginal populations across time and settler-colonial space due to the protracted pace of frontier ‘development’. Revealing the mediated historical aspects of structural racism is crucial to analysing the persistence of racialised policing in postcolonial settings and understanding why, despite repeated inquiries into mistreatment of Aboriginal people, institutional inertia remains.
