The Aboriginal and Torres Strait Islander smoking epidemic:What stage are we at, and what does it mean?

Smoking is the leading contributor to the burden of disease among Aboriginal and Torres Strait Islander Australians, and there is considerable potential for change. Understanding the epidemic stage may provide insight into probable trends in smoking-attributable mortality, and inform program and policy development. Tobacco use among Aboriginal and Torres Strait Islander Australians has declined substantially, accompanied by declining tobacco-related cardiovascular mortality. Based on the available evidence, we expect tobacco-related cancer mortality to remain high, but peak within the next decade; however, there is a critical need for improved evidence to make an accurate assessment. The continuation and expansion of comprehensive tobacco reduction measures is expected to further decrease tobacco use. Health gains will be observed over both the short and long term

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

Knowledge translation in Aboriginal and Torres Strait Islander research contexts in Australia: scoping review protocol

Introduction: Knowledge translation (KT) involves bridging the gaps between research knowledge and research application or practice, by sharing this knowledge with knowledge-users. KT is increasingly being used in research with Indigenous peoples globally to address the top-down and inappropriate research approaches commonly used in Indigenous research. Employing KT in Indigenous research in Australia is an emergent field, despite Aboriginal and Torres Strait Islander peoples having conducted KT for generations. There is limited evidence which demonstrates how KT is applied in the Aboriginal/Torres Strait Islander context. Results will benefit researchers by demonstrating ways of appropriately translating research findings to knowledge-users, including Aboriginal and Torres Strait Islander communities, researchers and policy makers. The scoping review will also inform a KT definition, method and practices used in a large-scale, longitudinal cohort study of Aboriginal and Torres Strait Islander adults: the Mayi Kuwayu Study. Methods and analysis: Under guidance of an Aboriginal and Torres Strait Islander governance committee, we will conduct a scoping review on KT in Aboriginal/Torres Strait Islander research. We will follow the scoping review method outlined by the Joanna Briggs Institute. We will search the ANU SuperSearch, and grey and hard to find literature in June 2022. Abstracts and full-text articles will be screened by two independent reviewers. We will include studies that relate to KT in Aboriginal/Torres Strait Islander research, regardless of the research topic. Results will be used to inform the KT definition, method and practices that can be used in Aboriginal/Torres Strait Islander research contexts in Australia. Ethics and dissemination: The Mayi Kuwayu Study has ethics approvals from the Australian Institute of Aboriginal and Torres Strait Islander Studies, 12 Aboriginal/Torres Strait Islander organisations, and the Australian National University Human Research Ethics Committee. Results will be disseminated through peer-review publication and community workshops. Protocol registration is available online (10.17605/OSF.IO/JMFQ3)

Study protocol - Indigenous Australian social networks and the impact on smoking policy and programs in Australia: Protocol for a mixed-method prospective study

Background: Tobacco use is the most preventable cause of morbidity and mortality in Australia. Comprehensive tobacco control has reduced smoking rates in Australia from approximately 34 per cent in 1980 to 15 per cent in 2010. However, 46 per cent of Abo

Data Analysis of Zoonoses Notifications in Aboriginal and Torres Strait Islander populations in Australia 1996-2021: Implications for One Health

Introduction: Zoonoses are a health concern for Aboriginal and Torres Strait Islander peoples in Australia that face elevated risk of disease related to the environment and animals. Internationally, One Health is encouraged to effectively manage zoonoses by taking integrated approaches involving animal, human, and environmental health sectors to improve health outcomes. However, Australia’s health systems manage zoonotic diseases in animals and people separately which does not support a One Health approach. For the effective management of zoonoses, a strong evidence base and database regarding the epidemiology of zoonotic pathogens is needed. However, we currently lack this evidence limiting our understanding of the impact of zoonoses on Aboriginal and Torres Strait Islander populations.Methods: As a first step towards building the evidence base, we undertook a descriptive analysis of Aboriginal and Torres Strait Islander zoonotic notifications in Australia from 1996 to 2021. We presented notifications as annual notification rates per 100,000 population, and percentages of notifications by state, remoteness, sex, and age group.Results: Salmonellosis and campylobacteriosis were the most notified zoonoses with the highest annual notification rates of 99.75 and 87.46 per 100,000 population, respectively. The north of Australia (Queensland, Northern Territory and Western Australia), remote and outer regional areas, and young children (0–4 years of age) had the highest percentages of notifications.Discussion: To our knowledge, these findings are the first national presentation of the epidemiology of zoonoses within Aboriginal and Torres Strait Islander populations. A greater understanding of transmission, prevalence and impact of zoonoses on Aboriginal and Torres Strait Islander peoples (including animal and environmental health factors) is required to inform their effective management through a One Health approach

Combining historical agricultural and climate datasets sheds new light on early 20th century barley performance

Barley (Hordeum vulgare ssp. vulgare) is cultivated globally across a wide range of environments, both in highly productive agricultural systems and in subsistence agriculture and provides valuable feedstock for the animal feed and malting industries. However, as the climate changes there is an urgent need to identify adapted barley varieties that will consistently yield highly under increased environmental stresses. Our ability to predict future local climates is only as good as the skill of the climate model, however we can look back over 100 years with much greater certainty. Historical weather datasets are an excellent resource for identifying causes of historical yield variability. In this research we combined recently digitised historical weather data from the early 20th century with published Irish spring barley trials data for two heritage varieties: Archer and Goldthorpe, following an analysis first published by Student in 1923. Using linear mixed models, we show that interannual variation in observed spring barley yields can be partially explained by recorded weather variability, in particular July maximum temperature and rainfall, and August maximum temperature. We find that while Archer largely yields more highly, Goldthorpe is more stable under wetter growing conditions, highlighting the importance of considering growing climate in variety selection. Furthermore, this study demonstrates the benefits of access to historical trials and climatic data and the importance of incorporating climate data in modern day breeding programmes to improve climate resilience of future varieties

Indigenous health program evaluation design and methods in Australia: a systematic review of the evidence

OBJECTIVE: Indigenous Australians experience a disproportionately higher burden of disease compared to non-Indigenous Australians. High-quality evaluation of Indigenous health programs is required to inform health and health services improvement. We aimed to quantify methodological and other characteristics of Australian Indigenous health program evaluations published in the peer-reviewed literature. METHODS: Systematic review of peer-reviewed literature (November 2009-2014) on Indigenous health program evaluation. RESULTS: We identified 118 papers describing evaluations of 109 interventions; 72.0% were university/research institution-led. 82.2% of evaluations included a quantitative component; 49.2% utilised quantitative data only and 33.1% used both quantitative and qualitative data. The most common design was a before/after comparison (30.5%, n=36/118). 7.6% of studies (n=9/118) used an experimental design: six individual-level and three cluster-randomised controlled trials. 56.8% (67/118) reported on service delivery/process outcomes (versus health or health risk factor outcomes) only. CONCLUSIONS: Given the number of Indigenous health programs that are implemented, few evaluations overall are published in the peer-reviewed literature and, of these, few use optimal methodologies such as mixed methods and experimental design. Implications for public health: Multiple strategies are required to increase high-quality, accessible evaluation in Indigenous health, including supporting stronger research-policy-practice partnerships and capacity building for evaluation by health services and government.This research received support from the Australian Primary Health Care Research Institute, Australian National University

One Health in Indigenous Communities:a critical review of the evidence

Indigenous populations around the world face disproportionately high rates of disease related to the environment and animals. One Health is a concept that has been used effectively to understand and address these health risks. One Health refers to the relationships and interdependencies between animal, human, and environmental health and is an emerging research field that aligns with indigenous views of health. To understand the applicability of One Health in indigenous communities, a critical review was undertaken to investigate evidence of One Health research in indigenous communities internationally, assess the strength of evidence, and understand what gaps are present. This review included the appraisal of twenty-four studies based in five regions: Canada, Africa, Australia, South America, and Central America. The review found that there is a need for studies of high strength, with rigorous methods, local leadership, and active involvement of indigenous viewpoints, to be undertaken in indigenous communities internationally that focus on One Health. It highlights the need to further consider indigenous viewpoints in research to reduce limitations, increase effectiveness of findings, consider appropriateness of recommendations, and benefit communities
