Abstract

:
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.

1. Introduction

International epidemiological research has established a persistent health gap to exist between Indigenous and non-Indigenous populations [1]. Indigenous peoples worldwide have higher morbidity and mortality rates, poorer nutrition, a life expectancy of up to 20 years less than non-Indigenous counterparts [2]. Globally, over 50% of Indigenous adults over 35 years of age have a Type 2 Diabetes Mellitus (T2DM) diagnosis, reaching epidemic proportions in some communities [2]. T2DM is one of the fastest growing diseases in Indigenous communities, with rates up to six times higher than the general population [3]. Despite some improvements in recent years, there is still a profound health gap that exists between these two populations [4], thus rationalising ongoing research in this area.
In 2004, The World Health Organisation (WHO) strategy on diet, physical activity, and health highlighted a strong link between sugar and non-communicable chronic disease (NCCD) risk [5]. Later, Johnson et al. [6] also found undeniable associations between sugar consumption and T2DM prevalence, noting a steady increase in sugar consumption over the past 200 years was paralleled with a similar increase in T2DM rates. Concurrent rises in soft-drink sales are suggested to have contributed substantially to overall sugar consumption [7]. Multiple factors influence the development of NCCDs in these communities [8]; however, in recent years, international research has identified SSB consumption to be directly associated with NCCDs, including T2DM [9,10]. Similar conclusions can be drawn from looking specifically at Indigenous populations. For example, studies in First Nations Australians, Alaskans, and American children have found SSB consumption to be significantly associated with dental caries severity and prevalence, as well as childhood obesity, T2DM, and other adult NCCDs [11,12]. This suggests that high SSB consumption can predispose NCCDs.
Indigenous populations have notoriously high rates of SSB consumption. Over 75% of beverages consumed by Native Alaskan children were some forms of SSB [13], and approximately four in five African American people consume SSBs [14]. Inuvialuit, American Indian, and American Indian children consumed approximately 300 kcal per day of SSB [13,14,15], contributing almost 20% to their recommended total daily energy intake [14,16]. Without even considering free sugar in food, this is already exceeding the WHO recommendation that intake of free sugars should be limited to less than 10% of dietary energy [17]. Alarmingly, a quarter of First Nations Children in Australia aged 6–24 months old have also been exposed to, and consumed SSBs [18], despite the overwhelming evidence shaping guidelines to advocate against this [19,20]. Furthermore, according to the Australian Aboriginal and Torres Strait Islander Health Survey in 4109 people, First Nations Australian people consumed 15 g more free sugars than non-Indigenous people and derived a higher proportion of free sugars from beverages than non-Indigenous people (67% compared to 51%) [17]. This is a substantial difference and is worthy of further investigation given the effect of sugar intake on the development of NCCDs.
The issue is exacerbated further in remote Indigenous communities where a plethora of additional challenges related to the “tyranny of distance” impact the costs of fresh food, leading to fragility of the food supply, dependency on the local store to receive food and drink, and ultimately, food insecurity [21,22]. This may allude to why previous literature has reported soft drink consumption in remote Indigenous areas to be higher than in an urban Indigenous setting [23,24]. Therefore, this literature review encompasses studies completed in the remote context in First Nations populations.
There is a gap in the published literature and poor clarity around the reason/s for the high rates of SSB consumption in remote Indigenous communities. The focal point of many studies in this area centres around interventions to reduce SSB intake [25], thereby highlighting the community’s ‘deficits’ have been researched on [26]. Past attempts to decrease SSB consumption in remote Indigenous communities in Australia have involved increasing access to a safe water supply, removing top selling SSBs from store shelves, introducing price discounts to artificially sweetened beverages, altering store marketing techniques, educating communities of the risks of high SSB consumption and altering/creating policies [8,25]. Despite these concerted efforts, and noted achievements such as decreased intake of sugar, increased availability and affordability of healthy foods, and consequent improvement in some nutrient intakes, Lee et al. [21] have found that there has still been an overall decrease in diet quality in First Nations people since 1986.
An understanding of factors that influence high rates of SSB consumption in remote Indigenous communities is lacking in the published literature. This is leading to ineffective interventions, trial and error, and much confusion and speculation about the best approach to decrease SSB consumption and improve Indigenous health. By having a clearer understanding of the root cause/s for SSB consumption in Indigenous communities, future research in this area has a greater likelihood of empowering these communities to improve their health. If the situation remains unaddressed, trends will continue along their current trajectory; increased burden of disease and increased SSB consumption. The United Nations (UN) recognise that Indigenous peoples’ health merits special attention, and have urged local, national, and international action to address the root economic, social, and environmental causes impacting Indigenous people’s health [2]. This is also echoed by The Lancet, which recommends recognition of social determinants, specifically local social, cultural, and historical contexts, prior to intervening in Indigenous communities [27]. Moreover, one of the four key objectives of the WHO Global Strategy on diet and physical activity is to monitor key influences on diet [5], and The UN Sustainable Development Goals for 2030 declaration explicitly calls for action in empowering, educating, and engaging Indigenous peoples [28]. Therefore, the aim of this scoping review is to understand the most frequently reported factors that contribute to SSB consumption in remote Indigenous communities. The implications of this literature review are far-reaching as the determinants for SSB consumption can form the basis of future health empowerment strategies in these remote communities and may be the missing puzzle piece in closing the gap.

2. Materials and Methods

2.1. Information Sources and Search Strategy

Eligible studies were identified through the following databases: Embase, Medline, Cinahl, Web of Science, and PsycInfo. The review protocol was developed according to the PRISMA framework [29]. The search string in the Browne et al. [25] paper was used as a guide, and to ensure all specific and relevant vocabulary choices and terminologies were captured. Medical Subject Headings (MeSH) terms for keywords were also incorporated into the search string, where the database permitted. To finalise the search string, it was edited and reviewed by all authors. These steps optimised the comprehensiveness of the review. The search and MeSH terms were initially developed for Medline, then adjusted using the SR-Accelerator polyglot function for Embase, Cinahl and Web of Science [30]. The PsycInfo translation was completed manually. These search strings can be found in Table 1. Eligible studies were also identified through grey literature by conducting organisation searches and citation searching. A Google search was completed, paralleled with discussions within the research team to identify relevant authorities, organisations, and stakeholders. Subsequently, four organisation websites were searched using key words and phrases. Each retrieved result containing all three keywords (SSB, Indigenous, remote) and/or synonyms in the title and/or abstract where appropriate were selected for screening. Citations within several relevant literature reviews were also screened. Relevant articles were then added to the screening pool.

2.2. Eligibility Criteria

Eligibility criteria for study inclusion were (i) published since 2000; (ii) written in English; (iii) performed on humans; (iv) observational or exploratory in nature; (v) discussed factors, determinants, contributors and/or influences of diet behaviours; and (vi) discussed food/diet patterns/behaviours. There did not necessarily need to be mention of SSB in the title or abstract for a study to be included as the authors did not want to disregard the potential of missing papers that only mentioned SSB in the full text, and the research team was unable to perform full-text searches on several of the databases.
The exclusion criteria were (i) literature reviews; (ii) in vitro studies; (iii) protocol papers; (iv) papers reporting solely on the health impact of SSBs; and (v) papers that only discussed the amount of SSB consumption.
Additional decisions were made during the full text review phase, which meant articles with the following characteristics were also not included (i) reporting on an intervention; (ii) no mention of SSBs; (iii) factors influencing SSB consumption were implied; (iv) not adhering to the traditional article format of introduction, methods, results, and discussion. Articles with the following characteristics remained included (i) factors discussed in the results and/or discussion section, so long as they were discovered from the findings of the paper and not supporting literature; (ii) studies where no primary data were used, but there was additional analysis performed on the already-existing findings/data sets.

2.3. Selection Process and Data Collection

Eligible papers were transferred to EndNote and exported to Covidence; a software used to streamline the SLR process, on 18 March 2022 [31]. All duplicate papers were removed automatically. Phase 1: Title and abstracts were screened by to exclude papers that did not meet the inclusion/exclusion criteria. Screening required consensus between two reviewers, otherwise the study would appear as a conflict. The authors deliberated all conflicts until a unanimous decision was reached. Phase 2: The full text of accepted papers was screened to determine which papers would be included in the review. This screening phase required consensus regarding reason for paper exclusion, therefore an exclusion hierarchy was established to reduce contention when eliminating papers. Again, the authors collaborated to resolve any conflicts. Phase 3: The study selection process remained conservative until the final phase, where the eligibility criteria were further refined, and the accepted studies were extracted for data.

2.4. Data Extraction

Key characteristics were obtained for all included studies and transferred into a standardised table. In a separate table, all information pertaining to influencers of SSB consumption were compiled.

2.5. Data Synthesis

Thematic analysis was used to synthesise the data set. Open coding was used to highlight relevant data in a systematic way. It should be noted that data were only pulled when directly relating to SSBs, as opposed to food choice in general. This information was then categorised and collated into potential themes. These themes were then reviewed and refined as needed. Finally, these factors were aligned with the Determinants of Nutrition and Eating (DONE) Framework using deductive coding by two authors who were experienced with qualitative research [32]. Any discrepancies in this process were resolved by consensus.

2.6. Quality Assessment

The Mixed-Methods Appraisal Tool Version 2018 (MMAT) was used to appraise and critique the methodological quality of studies from a range of designs, including qualitative research, quantitative descriptive research, and mixed methods research [33]. The relevant criteria were assessed for all included studies. A random 30% sub-set of the included papers were cross-checked by a different author. A detailed rating for each criterion is presented, rather than an overall score, to better inform the quality of the included studies [33].

3. Results

3.1. Study Selection

Identification and selection of studies is summarised in Figure 1. The search string yielded 2529 studies, of which Covidence automatically removed 1096 duplicates, leaving 1433 to screen from databases. From here, 1269 studies were excluded based on the tile and abstract, resulting in 164 studies for full text review. A total of 137 full texts were excluded primarily due to the paper not relating to SSB. Concurrent to database searching, the authors also identified 54 studies from other methods: 28 from organisation searching and 26 from citation searching. Of these, 20 papers were found to already be included in database searching, so these duplicates were manually removed. The remaining 34 articles were assessed for eligibility, where 27 were excluded, primarily due to being the wrong article type. The two article recruitment streams resulted in a total of 34 studies to be included in the review.

3.2. Quality Assessment

All studies received a ‘yes’ for the first two screening questions which asked whether studies had a clear research question and had data collected which would allow the research question to be addressed. In total, 65% of the included studies (n = 22) scored ‘yes’ for all relevant criteria. For the studies that had a quantitative design (n = 8), under 40% (n = 3) scored a ‘yes’ for all criteria. The most common reason the other studies did not achieve this is due to the risk of nonresponse bias. There were several instances where there was no explanation for a significant drop in participation rates over time or for when there was a high refusal rate. For studies that had a mixed-methods design (n = 7), the general concern was that many studies did not adequately provide a rationale for utilising a mixed-methods design or did not adhere to all the qualitative and quantitative criteria. This resulted in just under 60% (n = 4) of these papers achieving ‘yes’ for all criteria. Finally, for the studies that had a qualitative design (n = 19), over 75% (n = 15) received a ‘yes’ for criteria 1.1–1.5. The main concern regarding the four remaining studies was whether the qualitative approach and data collection methods were adequate to address the research question, and oftentimes it appears the study’s quality would have been enhanced from addition of a quantitative element. Refer to Table 2 for the full quality assessment and Table 3 for MMAT criteria.

3.3. Study Characteristics

Of the 34 included peer-reviewed studies, 50% (n = 17) were from Australia [34,35,38,39,43,44,46,48,53,54,55,57,58,59,61,65,66], seven were from USA [36,40,47,60,62,63,67], four from Canada [42,45,50,56], one was from Africa [37], one from Mexico [41], one from Guatemala [49], one from Ecuador [51], one from Brazil [52], and one from New Caledonia [64]. All studies were published within the past 20 years, with the oldest being 2004 [34] and the most recent being published in 2022 [62]. The included articles were a mix of qualitative study design (n = 19) [35,38,41,43,44,46,47,48,49,50,51,52,53,54,55,57,62,63,65], quantitative (n = 8) [34,39,42,45,58,64,66,67], and mixed-methods (n = 7) [36,37,40,56,59,60,61]. The number of participants in each of the studies ranged from 15 mothers in a qualitative study [48], to 1283 caregivers in one of the quantitative studies [58]. Two of the included studies used pre-existing survey data [34,66], while all others collected primary data. Data were collected from a range of different stakeholder perspectives including caregivers and families, health professionals, adult community members, and elders. Data collection methods were mainly focus groups (n = 13) [35,37,40,50,52,53,54,56,57,59,60,62,63], interviews (n = 18) [35,36,38,40,41,43,44,46,47,48,49,51,53,54,55,56,61,65], and surveys (n = 13) [34,36,37,39,40,42,45,58,59,60,61,64,67], with other methods such as shop inventory (n = 1) [40], water quality testing (n = 1) [56], and point-of-sale data (n = 1) [66] also being used. Broadly, the aims of the included papers were to investigate and explore remote Indigenous food environments, to increase understanding of how these food systems operate, and to report on challenges or barriers influencing SSB intake. Refer to Table 4 for more details on study characteristics.

3.4. Review Outcomes

Thematic analysis of included studies revealed 37 factors which influenced SSB consumption in remote Indigenous communities. Figure 2 presents the 15 most identified factors that have been mentioned in three or more papers. These codes, or factors were further synthesised into four overarching domains, which were further categorised into the stem and leaf level of the DONE framework, guiding the formulation of conclusions and recommendations [32]. Figure 3 provides an overview of the domains and codes. All extracted data are provided in Table 5, Table 6 and Table 7 for qualitative, mixed-methods, and quantitative papers, respectfully.

3.4.1. Individual Level

Studies identified nine factors encompassing biological, psychological, demographic, and situational domains at the individual level influencing SSB consumption. The most common was taste preferences, described by 19 papers as a determining factor of SSB intake. Papers referred to SSB as palatable [34], tasty [35], popular [47], thirst-quenching [51], difficult to give up [61], addictive [65], and one of their favourite foods [41]. Despite health literacy being the third most common factor to influence SSB intake, several papers reported that even when participants were aware that SSB were unhealthy, they drank them anyway [41,46,64]. There was a consensus among all included papers that young children and adolescents consumed the most SSBs, whether the evidence was in the form of regression analyses [42,45,58,59,67], or direct quotes/observations [40,47,56,57]. However, there was disagreement about which gender consumed the most SSBs, as some papers reported it was males [45,67], while others reported it was females [42], and some papers found gender to have no influence on SSB intake [58,59].

3.4.2. Interpersonal Level

Studies identified 16 factors in the social and cultural domains of interpersonal relationships to influence SSB intake. The concept of autonomy emerged, particularly when discussing child behaviours. Despite authority figures informing or advising children not to have so many SSBs, studies reported it was ultimately up to the children to make this decision independently [35,38,40,63]. More generally, it was identified that food was an important part of the individual autonomies of Indigenous people, and this was valued more highly than changing their diet to elicit potential health benefits [41]. Relating to cultural values is traditional practices, which have been shown via regression analyses to be inversely related to SSB consumption [42,45,58]. Older Indigenous participants have identified that the current style of eating is relatively recent [41] and diets have changed vastly since their own childhoods [51]. They never had to worry about sweets but now they do [54], and they are concerned generations to come will lose their taste for traditional foods in the face of sugar-laden newcomers such as SSBs [62,63]. The included papers had a large focus on child–parent dyads, and many influential factors of SSB consumption were related to parental actions, beliefs, and demographics. For example, in some studies parents reported using SSBs as a reward for when their children were well-behaved [38,48,50,53,54,63]. In one study, parents believed there were more important things to worry about than their children drinking SSBs [59]. It was also found that younger mothers and those who smoked were more likely to give their children SSBs [59].

3.4.3. Environmental Level

The included studies identified nine factors at the micro, meso, and macro domains of the environmental level. The general consensus among included papers was that SSBs were cheaper than healthy foods/alternatives [37,40,47,51,56,63]. While affordability was identified as a factor, one paper reported that Indigenous people do not consider the price of SSB in their purchasing decisions and that the want/desire is a stronger influence [65]. SSB sales in remote Indigenous communities are often mediated by other characteristics of the living area. For example, less than 50% of children aged 0–3 years of age with adequate access to health care consumed SSBs, in contrast to 75% of children without adequate access to health care [59]. Poor water quality has also been shown to influence SSB consumption via SSB addition to mask the colour or taste [56], diversionary drinking to conserve water [56], and due to perceptions that SSBs are healthier [39], safer [51,59], tastier [34,44,51,56,59,64], more aesthetically pleasing [44], cheaper [51,56,59], and more available [51,56], than local water sources. Availability of SSBs was the second most mentioned factor, referred to in 15 of the 34 included studies, as SSBs were described as being omnipresent [41], well-stocked [47], ubiquitous and unavoidable [54] in remote Indigenous communities.

3.4.4. Policy Level

At the policy level and within the government stem, there were three factors that influenced SSB intake. In focus group discussions, it was identified there were not many SSB consumption policies in place [47], and Myers et al. [53] have identified that this may be an effective avenue to reduce SSB consumption. Within community stores, the store owners were identified as key proponents of community SSB purchasing and consumption, particularly if they ordered and stocked large quantities of SSBs [40,47]. One paper mentioned that small community stores were often exploited by private enterprises, ultimately resulting in higher consumption of SSBs [54].

4. Discussion

The aim of this scoping review was to understand the most frequently reported moderators of SSB consumption in remote Indigenous communities in the published literature. After extraction from the 34 included studies, 37 different factors were summarised into the domains of the DONE socio-ecological framework. This facilitated the collation of results into: (i) 9 “individual level” factors; (ii) 16 “interpersonal level” factors; (iii) 9 “environmental level” factors and (iv) 3 “policy level” factors. Some of the factors were novel, while others had previously been identified in published work in Indigenous and other populations. Many of these factors influencing intake have been reported on, researched, and targeted in interventions to reduce SSB intake for several decades; however, interventions have not been effective and the problem of SSB consumption is ongoing [68]. The lack of a comprehensive and holistic understanding of factors influencing SSB consumption in remote Indigenous communities may be driving this problem and limiting the effectiveness of current strategies. Our scoping review helps to fill this gap. A key finding was that taste preferences were the most common factor influencing intake; however, no previous studies have considered this and incorporated it into strategies. Our results also showed that determinants of SSB intake stem from all different levels of the DONE framework, highlighting why strategies using a deficit-based approach are not appropriate. It is well-established that a deficit-discourse approach to research with Indigenous people results in disempowerment and has been identified as a barrier to improving health outcomes in communities [26]. Re-framing of this problem-based paradigm to a strengths-based approach [69], involving a deep consideration of First Nations people’s values, culture, and environment, fosters empowerment within Indigenous communities; a critical component to achieve improved health of this group. In relation to the practical application of the DONE framework, our findings provide impetus for focusing on individual, interpersonal and environmental level factors with communities, rather than enacting change from a policy/governmental level. These top-down approaches cannot be expected to work if the individual’s demographics, habits, and beliefs are not considered or accounted for.

4.1. Individual Level Factors Moderating SSB Intake

Age was found to influence SSB consumption, as children and young adolescents were more likely to consume SSBs than adults and older community members [42,45,58,59,67]. This trend was consistent internationally. While the reasons for this remain unclear, previous longitudinal research has suggested the innate preference for sweetness at birth and in the early years of life declines over time, and may be superimposed by maturational changes, hormonal changes, as well as many other behavioural and environmental factors [70]. The findings of the current study highlight that children should be a focus of future strategies to reduce SSB consumption, as this will improve the health of the next generation and influence family and community preferences [58]. This aligns closely with the broader realisation in public health nutrition that children can act as major agents of change and form an instrumental component of interventions targeted at improving family and community health [71]. The findings in this study also support The Lancet’s calls for risk reduction in children to be a much higher priority than it currently is [72].
Poor health literacy was reported to influence SSB consumption in 12 of the 34 studies. Previous studies have identified low health literacy to be highly prevalent within remote Indigenous communities [73], and to be an important social determinant of health [74]. Past interventions have trialed nutrition education sessions in communities or in schools aiming to decrease SSB consumption, and while these interventions are often found to improve knowledge, it appears they are not sufficient to facilitate behaviour change to actually reduce SSB intake [8]. This notion of knowledge and education not influencing actions was also identified in the current review [55,64], implying that a higher health literacy does not guarantee a healthier beverage is chosen. Even when applied in conjunction with another factor such as a price discounts on diet-SSBs, nutrition education is shown to have no extra added benefit to improving diet quality or reducing regular SSB purchases [75]. This may suggest the taste of the regular SSBs is a paramount influencer of consumption.
Taste preferences is another factor at the individual level that contributes to high SSB intake in remote Indigenous communities. The current study found this factor to be most influential, and was consistently observed to influence SSB consumption of Indigenous populations across the diverse range of countries included in this review. Despite this, to the authors’ knowledge there are no interventions within this population group based on taste or preferences. Dono et al. [76] stated that interventions targeting this purchasing decision are warranted. An Australia-wide survey has also found taste to be a ubiquitous reason for purchase [76], implying that this factor is not unique to Indigenous communities. However, as previous literature has consistently reported that First Nations people preferred significantly higher concentrations of sugar than non-Indigenous counterparts [77], and two of the included studies expressed that Indigenous people were feeling physically addicted to SSBs [61,65], it may be that the desire for the taste of SSBs is heightened in Indigenous populations.

4.2. Interpersonal Level Factors Moderating SSB Intake

The highest number of factors influencing SSB intake were categorised in the interpersonal level of the DONE framework. This is due to many of the included studies reporting on child/parent relationships. The findings of this review emphasised the role of autonomy as an important cultural belief that influences SSB intake in these communities. The belief that adults and children have the right to choose when, where, and what they eat [38] is deeply valued and engrained within Indigenous culture, which is why interventions such as soft drink bans may erode this cultural value [65]. In Australia, published work indicates this has influenced food choice among Indigenous people for over 40 years [78]. Conversely, in most Western families, parents are primarily responsible for decisions around food provision and dining [79]. A qualitative study on Western groups has also found parental practices such as using SSBs to reward good behaviour influenced overall intake [79]. Similarly, this practice was also identified within Indigenous settings, as SSBs were found to commonly be used by parents as incentives or treats, which subsequently increased total daily intake of SSBs [38,48,50,53,54,63]. Given that many Indigenous parents admit difficulty saying no to their child when they ask for sweet drinks [38], the impacts of using SSB as a parenting tool are likely compounded within Indigenous communities by the cultural significance of autonomy.
Although the traditional cultural approach to eating behaviour may have nurtured self-sufficiency within a largely safe, healthful, traditional food environment, in a commercially driven, colonised world it has been described as challenging and problematic [80]. The culmination of colonial practices such as relocating Indigenous people to missions, the provision of food rations, forced reduction in hunting and gathering, and separating mothers from their children has interrupted intergenerational knowledge transfer which has contributed to the cyclical loss of culture and traditional feeding practices [59,81]. This presents a culturally unique challenge to consider when attempting to decrease SSB consumption in Indigenous communities. A study included in this review found that the nutrient transition and loss of Indigenous culture over the past few decades has decreased diet quality and increased SSB consumption [42]. A recurring justification throughout studies was that sugar consumption is a habitual behaviour, formed during mission times when packet sugar was a staple food provided to Indigenous people [8]. Other research has supported this in a broader sense, which has found accelerated urbanisation and globalisation has resulted in profound decreases in diet quality of Indigenous people [82].

4.3. Environmental Level Factors Moderating SSB Intake

Our review found availability to be the second most popular factor influencing SSB intake. In contrast to the traditional practices of living and eating from the land, remote Indigenous communities have become heavily reliant on their local convenience stores, with increased SSB consumption as a consequence [21,81]. Previous interventions have aimed at targeting the availability of SSBs by removing the top three selling soft drinks from the convenience store [83]. While this was shown to be effective at decreasing consumption of SSBs in the short term, sustainability and translation into improved health outcomes is unclear [83]. For example, an Indigenous community in one of the included studies identified that nothing is stopping people from visiting a neighbouring store to purchase the soft drink that they prefer the taste of, again indicating that taste preferences for the drink is a highly influential factor [54].
Past interventions have discounted the prices of diet or artificially sweetened beverages by up to 20%, but this did not affect SSB sales [75]. Data from the current review revealed that SSB are actually cheaper than water and diet drinks in some remote Indigenous communities, making it the most cost-effective choice where funds are often tight [40]. Previous studies have also suggested that Indigenous people will pay almost anything for something they want [68]. On the other hand, it is virtually impossible to give away anything that this group does not want [68]. This is another example of individual preference being the strongest predictor of SSB consumption.
A 2022 report by the UN has identified Indigenous people’s lacking access to safe water sources as a global issue, which continues to be eroded due to activities such as mining and development of large agricultural and livestock farms damaging and contaminating water sources and putting livelihoods at risk [84]. This review has revealed that poor water quality in remote Indigenous communities can result in higher SSB consumption via means such as diversionary drinking [56]. However, a past intervention has attempted to reduce SSB consumption by introducing water bubblers to the community [85]. Post-installation, they found that despite water intake increasing by 19 mL per person per day, there was a reduction in diet-carbonated beverages by 42 mL, and an increase in SSBs by 20 mL per person per day [85]. The findings of this independent study are also supported by a recent SLR, which concluded that there is limited evidence that interventions aimed solely at increasing water consumption actually reduce SSB intake [86]. This highlights that even in the presence of safe drinking water, Indigenous communities are still drawn to, and choose SSBs, possibly due to personal preferences and taste.

4.4. Policy Level Factors Moderating SSB Intake

At an institutional level, a dearth of policy and lack of rigour and evaluation of policy implementation has been shown to increase SSB consumption [47,85]. When discussing strategies to reduce SSB consumption, Indigenous community members often brought up putting a policy in place; to remove some of the power store owners face, to monitor cooking methods in a school and community setting, and to circumvent exploitation [47,54]. Making changes at an institutional level may appear to be the most efficient approach as it focuses on widespread change rather than changing one person’s behaviour. However, a recent SLR found that policies and interventions targeting Indigenous people that are implemented without Indigenous leadership or consultation do not improve nutrition outcomes and may be harmful [25]. Even when policies are community-driven, such as placing time restrictions on when SSBs can be sold and prohibiting children to purchase SSBs, it was found that these types of interventions are difficult to implement and inevitably create tension within the community [54]. As one community member pointed out, “if you stop it at the supermarket, they will go to the butcher shop or roadhouse” [54]. Other policies that have been tried include provision of healthy foods and drinks at childcare centres, removal of the top three selling SSBs from the community store, and income management where 50% of their social security payments were quarantined for essential purchases only (such as groceries) [25]. The caveats of these ideas are that they either rely heavily on funding, which is often not available long term, the policy is put in place with no follow-up or audit to ensure its implementation, it is inherently based on a top-down approach, and often lacks cultural sensitivity [25]. Therefore, while the concept of a policy is a good idea, caution must be taken in its implementation by working closely with the Indigenous community and harnessing their strengths to design it.

4.5. Limitations

A limitation regarding the evidence obtained was the language bias towards only including papers that were published in the English language. Therefore, the findings may not be translatable to all countries and cultures since the included papers primarily had Western-centric perspectives which is not representative of global diversity.
During the full text review and data extraction phase, there were occasions where it could not be differentiated whether the factor was for food or drink or both. As this literature review is only documenting factors for SSB intake, it became difficult to gauge whether the paper should be included, or the data should be extracted. Therefore, to minimise this limitation resulting in a bias, it was unanimously decided to exclude the information unless it explicitly related the factor to SSB consumption. However, the caveat of this decision is that there is so much rich data and information relating to food and drink choice more broadly that had to be excluded as it was unclear if it related directly to SSBs. The consequence of this is there are other potential factors that may influence SSB intake in remote Indigenous communities that are not noted here.
Finally, the authors found preference to be most common factor, which has been interpreted to mean it has the most influence on SSB intake. However, there is the possibility it could also mean it has just been studied the most, which may decrease the strength of this conclusion.
A strength of this paper is it is the first of its kind; an international scoping review with a quantitative component grouping factors influencing SSB consumption into the socio-ecological framework, and therefore produced highly novel findings with significant implications worldwide for further research in this area. Moreover, the methodology used throughout the review process was rigorous and thorough, as stages of screening and data extraction involved at least two reviewers to enhance the objectivity of results and remove any potential personal bias, and there were comprehensive extraction categories. Another strength of this paper lies in its investigation into the ‘why’, as identifying the root cause of SSB behaviour in remote Indigenous communities has been severely overlooked in pre-existing literature.

5. Conclusions

This literature review endeavoured to identify and summarise the factors influencing high SSB consumption within remote Indigenous communities. Using the DONE framework, the myriad of factors were grouped into different socio-ecological levels. A novel finding of this scoping review is that SSB intake is influenced by all levels of this framework, which offers insight into why previous top-down deficit-based strategies have had limited success, and why empowering these remote Indigenous communities from an Individual level is paramount. Another key finding from this review was that taste preferences outweigh all other factors for influencing SSB consumption. Despite past interventions targeting other avenues that our review has shown to be factors, such as water quality, SSB availability, policies, education, and affordability of SSBs, these interventions have not considered the individual’s taste preferences for SSB. These findings will enhance the approach taken and the effectiveness of further research and strategy development in this area, which should ultimately decrease SSB consumption and thereby positively influence NCCD levels in remote Indigenous communities.

The older participants raised a number of issues that they believed challenged parents’ ability to guide their children’s intakes, including the appeal and easy availability of so many different foods and drinks perceived as tasty, sweet, and convenient, and the autonomy children have to make their own choices.

The addition of often-excessive quantities of sugar to frequently consumed cups of tea was not considered to be a problem. Instead, they considered tea drinking to be an acceptable practice related to the past.

“Many mothers are not strong … They might not know the coke is bad, and also they can’t say no; they don’t know the story of coke and the fizzy drinks.”–Mother
-
“Mothers say ‘yes’ because they don’t have the full information on good food … If she knows the story she can close her heart to this bad food … Children need an education background before they have children.”–Grandmother
-
“In the traditional style a mother or grandmother can’t say no if a child wants something to eat … We tell kids what is there; it’s up to the children what to choose. If we see it’s not good food we tell them this will make you fat or get sick. What they eat, it is up to the children.”–Grandmother

One participant mentioned a male diabetic she knew, saying, “The diabetes affects the way that he lives. He has pain, his vision is worse, and he feels sicker all the time. The doctor told him that he needed to stop drinking … but it is part of his life. He cannot stop.”–Woman
-
When another participants husband who had diabetes had to get a blood test, the wife said “his blood glucose level was 383 [mg/dL]. And he couldn’t understand why it was so high. I tried to explain to him about eating better and drinking less [SSB and alcohol]. But he just told me that he would not stop drinking, and that he would keep [doing things] the same as he has always done.”–Women
-
SSBs are omnipresent in Tope and throughout Yucatan.
-
SSBs were available in large quantities at nearly every meal, even breakfast. Toddlers often received Coca-Cola in their bottles.
-
Physicians named SSBs as the biggest contributor to the diabetes epidemic and also consumed these products themselves.
-
While participants acknowledged changing their diets might have had health benefits, they placed greater importance on the role of food as an important part of their individual autonomies, personal relationships, and social interactions. Additionally, they were accustomed to their diet and did not want to give up their favourite foods.
-
Although some females recognised the importance of modifying their behaviours, most women with diabetes acknowledged familial duties and social stigmas were enough to prevent them from making meaningful changes, such as decreasing SSB consumption.
-
This style of eating was relatively recent, and unique to the past two or three generations.
-
Many participants acknowledged that SSB consumption was a risk factor for obesity, diabetes, and other negative health outcomes. Clinicians always recommend reducing or eliminating SSB consumption in diabetes patients. Despite this knowledge, almost all participants admitted to still drinking SSBs.

-
While flavoured additives, vitamin water, flavoured teas, and smoothies were available in several stores, they did not sell as well as soda/pop or the powdered drinks. Some storekeepers claimed price was a primary factor, while others felt it was because people bought what they were used to.
-
Most storekeepers indicated that diet soda/pop was not a popular item. Alternative healthy drink options, such as teas and smoothies, are carried in stores, but reportedly do not sell well because they are more expensive.
-
Storekeepers were aware of healthy options, but also knew these products were more expensive than unhealthy alternatives like SSB.
-
The storekeepers expressed how they are required to satisfy their customer base and, in several cases, company management- which means ordering large amounts of SSBs.
-
Fruit-flavoured juices were popular and appealing to young children.
-
For older kids, sports drinks were more popular and sold best in summer months and during sports seasons.
-
By far, the most well-stocked beverages in stores were sodas/pops.
-
When asked what people mostly drank, multiple storekeepers volunteered “soda” or “pop” as the beverage of choice.
-
Storekeepers agree that healthy beverages should be promoted, but pleasing customers is the priority, and none feels comfortable advising customers about food choices or telling them what they should or should not buy. However, purchasing policies that require healthy choices or limit unhealthy choices actually empower storekeepers with concrete actions they can enforce.

Some parents were unaware of the effects of sugary drinks on teeth or the seriousness of untreated tooth decay. Families reported not having avenues (Internet or television) to access information on caring for their children’s oral health, which contributes to seeming inaction on their part.

“My parents were not educated about these things. So, then they also weren’t able to educate us, we would always eat candy, chocolates, popsicles, soda. We had no idea what could damage our teeth. And they didn’t know to tell us that we should brush our teeth. If we wanted to brush, great; if not, that was fine too. So, that’s why my generation, we have such damaged teeth and so many caries, and even mouth pain.—Low-caries parent
-
A common theme among high-caries parents was how much diets had changed since their own childhoods. They discussed the challenge of preserving their healthy indigenous dietary traditions, primarily a low-sugar, plant-based diet. This was a particularly difficult struggle in the face of the allure of processed snacks and sugary drinks.
-
Parents described this nutrient transition in a context where stores began selling more processed snack foods and sugary drinks; more parents commenced wage-paying jobs outside the home; and both the access to and convenience of processed foods increased.
-
Many parents stated that they never drank soda as children and tried soda for the first time as adults. By the time they were adults with their own children, they believed that soda was more available, affordable, thirst-quenching, and safer than the local water sources.

Private enterprises exploit smaller communities targeting children through the sale of sugary foods and drinks.
-
Sugar also played a role in parenting whether it be by controlling its availability or using sugary food and drink to manage a child’s behaviour.
-
Sugar and processed foods were ubiquitous in remote communities and the ease of access adversely impacted on the nutritional preferences for children living in remote communities.
-
The marketing of sugar to appeal to children was found to further complicate parenting and influence food choices at community stores.
-
There was a sense that the accessibility to sugary food and drinks within larger towns was unavoidable. As a result, restrictions on the sale of sugary food and drink seemed to be too difficult to introduce in communities with several outlets.

“They (mothers) do not care for their babies’ health as many are not breastfeeding their babies. They give them juice which is sweet and they say babies like it.”–Grandmother
-
Although children preferred consuming snacks and juice rather than nutritious foods, mothers stated they would have been feeding them with good quality foods if they could afford to purchase them.

“Kool-Aid or Tang was pretty much the only thing the kids drank”–Head Start Instructor
-
“The little ones, if they are by themselves, they buy pop [soda]. If they are with their parents, they buy Gatorade. Little kids that can barely look over the counter will buy pop.”–Shop owner
-
While many young children frequently drank Tang, Kool-Aid and even sodas, many people in the village recognised that SSB consumption was unhealthy.
-
While most participants in the study recognised soda could cause excessive weight gain and did not provide vitamins or minerals, many did not realise that other drinks such as 100% juice and juice drinks could contribute to excessive caloric intake too.
-
SSB consumption begins early, with children as young as 1 year of age drinking SSBs in the village, as participants claimed to receive no instruction in nutritional practices from healthcare providers.
-
Young children regularly visit village shops without a guardian and are allowed to purchase soda and all SSBs.
-
Shop owners and consumers reported that soda was usually the first product to disappear from shelves, and that it was not unusual for the entire village to run out of soda.
-
People in the village would not come into the store if no soda was available and soda is responsible for generating human traffic into the stores.
-
Kool-Aid or Tang is priced 75% cheaper per serving than healthier beverages such as bottled water or milk.
-
Only the largest store in the village sold 100% juice, which was nearly double the price of a can of soda or half the price of a bottle of water.
-
Bottled water was available for purchase at 2 of the village’s 3 shops, and SSB was available at every store in the village.

“I gave up diet drinks over a year ago and I was doing very well but then [the community] ran out of water and when I had to drink water at $1.25 a bottle and I needed four [bottles] a day–there was no water available from the treatment plant–well, I couldn’t get fresh or clean water–I couldn’t afford to buy four bottles of water a day just for me. Pepsi was all that was available, and Pepsi was cheaper, so I went back on it. The boiled water is disgusting; it tastes disgusting. Pepsi is $1.10 compared to water, which is $1.25.”–Woman
-
High-sugar beverages cost 15 cents less than a bottle of water at the local store, and they were more consistently available. So, the choice was made to consume high-sugar beverages, although residents expressed serious concern about the negative effects of high-sugar consumption on health.
-
Water was always on peoples’ minds, especially before storms; hence, despite their knowledge of the potential health risks, people consumed untreated water and unhealthy high-sugar drinks. The residents understood the linkages between water insecurity and high rates of obesity, and they regretted their high-sugar intake, but they expressed a sense of helplessness.
-
To make water more palatable or to mask water with a brown cast (due to the high iron content or natural organic materials), parents offered Kool-Aid or a bottle of high-sugar-containing pop (Pepsi/Coca-Cola).
-
The residents managed the perennial water problem by conservation and recycling of water at home, reducing its intake and drinking high-sugar beverages as the alternative.
-
Water insecurity and poverty have resulted in a high intake of cheap sugary beverages as an alternative to water, particularly among children.

N/A
-
The prevalence of consumption of any SSB and individual SSB types was higher in older compared with younger age groups. For example, 29% of 0–12 month old’s had SSB, 56% of 12–18 month old’s had, and 66% of 18–36 month old’s had.
-
SSB consumption increased with number of children in the household
-
SSB consumption prevalence was significantly higher among children whose mother was ≤21 years old at their birth, and whose caregiver was non-employed.
-
SSB consumption prevalence was significantly higher for children whose caregivers had lower levels of family support, social network, and emotional support.
-
SSB consumption prevalence was significantly higher among children whose families were financially strained, and who were exposed to more stressors (e.g., racism, negative major life events).
-
For many families, there were ‘more important’ things to worry about, so what their children were drinking was not their highest concern.
-
SSB consumption prevalence was significantly higher among children who were exposed to smoke in utero, whose caregiver had poor social and emotional well-being and physical health, whose mother had no prenatal check-ups, who had inadequate access to health services and whose caregiver was a current smoker.
-
When concerned about water taste or safety, many people avoid drinking tap water and buy bottled water or other beverages; when bottled water is the same price as SSB, people may opt for SSB.
-
Without regular electricity supply, it is not possible to cool warm tap water. The warm climate of many remote areas also contributed to high SSB intake, with SSB perceived to quench thirst better than (warm) water.

2–5 years old children from food insecure households had significantly higher intake of soda and sports drinks compared to food secure households.
-
Adults in rural food insecure households had higher intake of 100% fruit juice and SSBs compared to rural food secure households.

“I’m normally addicted to um [cola soft drink brand] … I drink [cola soft drink brand] whenever I’m out”–Participant
-
Most participants (80%) identified that there are drinks that they would find difficult to give up, soft drinks (defined here as carbonated drinks, either unsweetened, sweetened, or artificially sweetened) being the main type of drink mentioned (70%).
-
A large number of participants were not aware of the need to, or not motivated to, change their SSB consumption behaviours.

4% of children believe sugary foods and soft drink are healthy for teeth and bodies
-
Over 12% of children did not consume tap water regularly and 5.1% identified tap water as ‘unhealthy’ for teeth and bodies.
-
There has been a history of poor water quality in some of the communities involved in this study, which could be contributing to the notion that water is ‘unhealthy’ and may be increasing the consumption of sugary drinks rather than water.
-
25% of parents believe bottles with liquids other than water, such as SSB, do not make a baby’s teeth unhealthy.

Men reported significantly lower percent energy from sugar-sweetened beverages and greater percent energy from traditional foods than women.
-
Being 51+ years old is strongly predictive of traditional food consumption and consuming <13% energy from high sugar beverages.
-
Being 31–50 years old is significantly more likely than the 51+ age group to consume more energy from high sugar beverages, and significantly less likely than the 19–30 years old group.
-
Being female is predictive of meeting the AMDR; however, it is also associated with lower likelihood of consuming < 13% energy from high-sugar beverages.
-
Consumption of TF predicted significantly greater likelihood of consuming <10% energy from saturated fat and <13% energy from high sugar beverages.
-
Total energy intake decreased significantly with increasing age as did the percent of energy from high sugar beverages.

The probability of sugar-sweetened beverages consumption was significantly higher among children who were not taught traditional practices, who had experienced housing instability, who had a bigger household size, and whose primary carers had lower levels of education, were not employed, and reported financial strain.
-
Overall, sugar-sweetened beverage consumption was higher among older children, with significantly higher odds of consumption for children aged 5–7 years compared to children less than 4 years of age. This may be a result of children’s increasing autonomy to make their own decisions.

-
Living environment, and knowledge about energy expenditure were significantly related to the quantity of SSBs consumed.
-
The adolescents categorised as “don’t know” for energy expenditure knowledge consumed significantly more SSBs (6.22 L per week) than the others did (4.26 L per week for adolescents who underestimated, 3.64 L per week for adolescents who gave an accurate answer, and 3.73 L per week for adolescents who overestimated the energy expenditure required to eliminate a SSB unit). The higher the estimated expenditure, the lower the SSB consumption.
-
Low SES was associated with higher SSB consumption (4.44 L/day compared to 3.11 L/day in high SES)
-
Participants that disagreed that consuming SSBs can cause weight gain drank more SSBs than those who agreed (4.82 L/day compared to 3.77 L/day)
-
In New Caledonia, SSBs are widely available near all schools before, during and after the school day.
-
People living in environments where access to drinking water is a problem might become suspicious of their water source, especially as the taste can be unpleasant. This might explain the preference for SSBs among some rural populations.
-
Even though most of the New Caledonian adolescents thought consuming SSBs can cause weight gain, they drank them regardless.

-
Compared to women, men had significantly lower health literacy scores, lower HEI scores, and higher intakes of SSBs.
-
Participants in the lowest health literacy category consumed about 119 kcal/day more SSBs than those with adequate health literacy (230 kcal/day compared to 111 kcal/day).
-
Each additional point in health literacy scores was associated with 34 kcal/day lower SSB intakes.
-
Each additional year older a participant was, 7 kcal/day less SSBs were consumed. This means 18 years olds had the highest SSB consumption.
