Sugar-sweetened beverage consumption among Indigenous Australian children aged 0-3 years and association with sociodemographic, life circumstances and health factors

Inequalities in dental caries among Indigenous and non-Indigenous children in Australia: A literature review

Dental caries constitutes one of the most ubiquitous diseases in Australia, with Indigenous children presenting a notably higher prevalence than their non-Indigenous peers. This literature review aims to update the knowledge base developed by Christian and Blinkhorn in 2012, with a particular focus on the contemporary disparities in dental caries between Indigenous and non-Indigenous children. Our research strategy involved a thorough exploration of the Medline, PubMed, and Scopus databases to identify pertinent studies published between 2009 and 2022. Supplementary resources included various government websites and citation searches. We prioritised studies that focused on children aged 5-6 or 12 years-reflecting the World Health Organization's index ages for oral health-and that reported dental caries prevalence and experience indicators. Our review methodology was guided by the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statement. The updated search, spanning 2009 to 2023, retrieved studies that reported caries estimates exclusively from 2009 to 2014. Within this period, the prevalence of dental caries in Indigenous children's primary teeth ranged between 52% and 77%, while the prevalence in permanent teeth varied from 36% to 60%. This updated review indicated that Indigenous children continue to experience caries at an approximately twice higher rate than non-Indigenous children, sustaining the persisting disparity in caries estimates. The findings from this review show that no discernible improvement in dental caries rates among Australian Indigenous children has been observed in comparison to the previous review; and that Indigenous children continue to experience both higher prevalence and severity of dental caries compared to non-Indigenous children.

Examining attitudes toward a proposed sugar-sweetened beverage tax among urban Indigenous adults: a qualitative study using a decolonizing lens

BACKGROUND

Sugar-sweetened beverage taxation has been proposed as a public health policy to reduce consumption, and compared with other ethnic or racialized groups in Canada, off-reserve Indigenous populations consume sugar-sweetened beverages at higher frequencies and quantities. We sought to explore the acceptability and anticipated outcomes of a tax on sugar-sweetened beverages among Indigenous adults residing in an inner-city Canadian neighbourhood.

METHODS

Using a community-based participatory research approach, we conducted semistructured interviews (November 2019-August 2020) with urban Indigenous adults using purposive sampling. Interviews were audio-recorded, transcribed verbatim and analyzed using theoretical thematic analysis.

RESULTS

All 20 participants (10 female, 8 male and 2 two-spirit) consumed sugar-sweetened beverages on a regular, daily basis at the time of the interview or at some point in their lives. Most participants were opposed to and concerned about the prospect of sugar-sweetened beverage taxation owing to 3 interconnected themes: government is not trustworthy, taxes are ineffective and lead to inequitable outcomes, and Indigenous self-determination is critical. Participants discussed government's mismanagement of previous taxes and lack of prioritization of their community's specific needs. Most participants anticipated that Indigenous people in their community would continue to consume sugar-sweetened beverages, but that a tax would result in fewer resources for other necessities, including foods deemed healthy.

INTERPRETATION

Low support for the tax among urban Indigenous people is characterized by distrust regarding the tax, policy-makers and its perceived effectiveness. Findings underscore the importance of self-determination in informing health policies that are equitable and nonstigmatizing.

Seeking Sweetness: A Systematic Scoping Review of Factors Influencing Sugar-Sweetened Beverage Consumption in Remote Indigenous Communities Worldwide

It is well-established that remote Indigenous communities have higher rates of sugar-sweetened beverage (SSB) consumption than non-Indigenous counterparts, which results in higher rates of chronic diseases such as type 2 diabetes mellitus (T2DM), obesity, and kidney disease. The aetiology leading to this behaviour remains understudied and overlooked. Therefore, the aim of this literature review is to understand the underpinning factors that contribute to SSB consumption in remote Indigenous communities. Studies were identified through five databases (n = 2529) and grey literature searching (n = 54). Following the PRISMA guidelines, each paper was assessed for eligibility, which left 34 studies for inclusion in the review. Within these papers, 37 different factors were found to influence SSB consumption in remote Indigenous communities. These were organised according to the Determinants of Nutrition and Eating (DONE) framework. SSB consumption was found to influence intake through each main level of the framework; individual (n = 9), interpersonal (n = 18), environmental (n = 9), and policy (n = 3). Preference was identified to be the most common factor to influence intake (n = 19), followed by health literacy (n = 15) and community availability (n = 12). Despite this, interventions to reduce SSB intake have never targeted this factor. This paper highlights the importance of a multi-level whole-of-system approach and suggests that an individual’s taste/preference should shape the direction of future research and intervention in this area.

Native and Indigenous Populations and Gastric Cancer: A Worldwide Review

Gastric cancer is a worldwide concern, particularly for Indigenous populations who face greater disparities in healthcare. With decreased access to screening and critical treatment delays, this group is experiencing adverse health effects. To determine what factors drive these disparities, a systematic review was performed in PubMed. This revealed a lack of research on gastric cancer specific to this population. The literature primarily focused on subset analyses and biological aspects with sparse focus on determinants of health. The results informed this presentation on factors related to Indigenous gastric cancer, which are influenced by colonialism. Indigenous populations encounter high rates of food shortage, exposure to harmful environmental agents, structural racism in the built environment, H. pylori, and compromised healthcare quality as an effect of colonialism, which all contribute to the gastric cancer burden. Putting gastric cancer into a cultural context is a potential means to respond to colonial perspectives and their negative impact on Indigenous patients. The objective of this manuscript is to examine the current state of gastric cancer literature from a global perspective, describe what is currently known based on this literature review, supplemented with additional resources due to lack of published works in PubMed, and to present a model of gastric cancer through the lens of a modified medicine wheel as a potential tool to counter colonial healthcare perspectives and to honor Indigenous culture.
