Rural nutrition and dietetics research-Future directions.

AIM: The aim of this study was to summarise key evidence from recent Australian rural nutrition research and provide recommendations for future nutrition and dietetics research with rural communities. CONTEXT: Clear evidence demonstrates that diet plays a role in the health gap between rural and metropolitan Australia. Despite the opportunity to address the health of rural Australians through better nutrition, alarmingly low investment in nutrition and dietetics research has occurred historically, and over the past decade. APPROACH: A review of the evidence was undertaken by rural nutrition and dietetics leaders to provide a commentary piece to inform future rural nutrition research efforts. CONCLUSION: Establishing strong, collaborative place-based nutrition and dietetics research teams are necessary to combat the significant gaps in the scientific knowledge of solutions to improve nutrition in rural Australia. Further, dieticians and nutritionists who live in and understand the rural contexts are yet to be fully harnessed in research, and better engaging with these professionals will have the best chance of successfully addressing the nutrition-related disease disparity between rural and metropolitan Australia.

HealthyRHearts - reducing cholesterol in rural adults via telehealth-based medical nutrition therapy: protocol for a cluster randomised controlled trial.

BACKGROUND: Few randomised controlled trials specifically focus on prevention in rural populations. Cardiovascular disease (CVD) contributes to approximately one quarter of deaths in Australia. Nutrition is a key component affecting many risk factors associated with CVD, including hypercholesterolaemia. However, access to medical nutrition therapy (MNT) is limited for people living in rural areas, potentially exacerbating inequities related to health outcomes. Telehealth services present an opportunity to improve MNT access and address healthcare disparities for rural populations. The present study aims to evaluate feasibility, acceptability, and cost-effectiveness of a telehealth MNT CVD intervention program in lowering CVD risk over 12-months in regional and rural primary health care settings. METHODS/DESIGN: A cluster randomised controlled trial set in rural and regional general practices in NSW, Australia, and their consenting patients (n = 300 participants). Practices will be randomised to either control (usual care from their General Practitioner (GP) + low level individualised dietetic feedback) or intervention groups (usual care from their GP + low level individualised dietetic feedback + telehealth MNT intervention). Telehealth consultations will be delivered by an Accredited Practising Dietitian (APD), with each intervention participant scheduled to receive five consultations over a 6-month period. System-generated generic personalised nutrition feedback reports are provided based on completion of the Australian Eating Survey - Heart version (AES-Heart), a food frequency questionnaire. Eligible participants must be assessed by their GP as at moderate (≥ 10%) to high (> 15%) risk of a CVD event within the next five years using the CVD Check calculator and reside in a regional or rural area within the Hunter New England Central Coast Primary Health Network (HNECC PHN) to be eligible for inclusion. Outcome measures are assessed at baseline, 3, 6 and 12 months. The primary outcome is reduction in total serum cholesterol. Evaluation of the intervention feasibility, acceptability and cost-effective will incorporate quantitative, economic and qualitative methodologies. DISCUSSION: Research outcomes will provide knowledge on effectiveness of MNT provision in reducing serum cholesterol, and feasibility, acceptability, and cost-effectiveness of delivering MNT via telehealth to address CVD risk in rural regions. Results will inform translation to health policy and practice for improving access to clinical care in rural Australia. TRIAL REGISTRATION: This trial is registered at anzctr.org.au under the acronym HealthyRHearts (Healthy Rural Hearts), registration number ACTRN12621001495819.

Experiences of co-designing research about a rural Aboriginal well-being program: Informing practice and policy.

OBJECTIVE: The objective of this study was to explore data and Aboriginal and non-Aboriginal researchers' experiences and reflexivity in co-designing research about a rural Aboriginal well-being program to inform practice and policy. SETTING: Gumbaynggirr, Birpai, Kamilaroi and Awabakal countries located in regional and rural New South Wales, Australia. PARTICIPANTS: Rural and regionally located research team who co-designed processes to challenge the status quo about a critically framed, rural-based Aboriginal well-being research project. DESIGN: Researchers drew on data from a research project in an interpretive cycle of collaborative Yarning. Data included 90 published articles, 12 Yarning transcripts and 26 reflective journal text sets, as well as researcher experiences and reflexivity. RESULTS: The Duguula Gayirray (Yarning together), Yandaarray (walking together) and Duguula Nguraljili (sharing together) co-design practice model was developed to represent key actions in the context of an Aboriginal well-being program in a rural context. Actions were supported by seven interpersonal ways of being and were underpinned by respectful relationships between community and researchers. DISCUSSION: Duguula Gayirray, Yandaarray and Duguula Nguraljili are critical to co-design practice and are grounded in respectful relationships. Our experiences led us to critique our perceptions of power sharing, equitable partnerships and collaborative knowledges towards opportunity for collective research co-design. CONCLUSION: Duguula Gayirray, Yandaarray and Duguula Nguraljili transformed our understanding of achieving liberation from dominant western research in the context of a rurally located Australian Aboriginal well-being program. This study contributes to progression of Aboriginal health research practice and policy recommendations, enabling real cultural change in health care with rurally located Aboriginal communities.

The Effectiveness of Randomized Controlled Trials to Improve Dietary Intake in the Context of Cardiovascular Disease Prevention and Management in Rural Communities: A Systematic Review.

BACKGROUND: Dietary intake is an important modifiable risk factor for cardiovascular disease. However, to our knowledge, there are no systematic reviews of nutrition interventions in the context of cardiovascular disease prevention and management within rural communities. This is important to investigate, given the unique geographic, social, and contextual factors associated with rurality. OBJECTIVE: Our primary objective was to systematically assess evidence on the effectiveness of randomized controlled trials to improve dietary intake in the context of cardiovascular disease prevention and management in rural communities. METHODS: Nine electronic databases were searched from inception to June 2020, including MEDLINE, The Cochrane Library, Embase, Emcare, PsycINFO, Scopus, Rural and Remote Health, CINAHL, and AMED. Randomized controlled trials that reported results of interventions with adult, rural populations and measured change in dietary intake compared to usual care, alternative intervention, or no intervention controls were included. Included randomized controlled trials were also assessed according to the TIDieR (Template for Intervention Description and Reporting) checklist and RE-AIM (reach, effectiveness, adoption, implementation, maintenance) framework. RESULTS: Thirteen articles reporting results of randomized controlled trials were identified. Included articles reported a range of nutrition interventions and measured 18 dietary intake outcomes. Most studies (n = 10) demonstrated effectiveness in altering at least 1 dietary intake outcome, including fruit and/or vegetable (n = 9), fiber (n = 2), Dietary Risk Assessment score (n = 2), energy, dairy, carotene, vitamin C and sodium (all n = 1). However, there was wide variation in the reporting of intervention components (according to the TIDieR checklist) and impact (according to RE-AIM framework), resulting in difficulty interpreting the "real-world" implications of these results. CONCLUSIONS: Through this systematic review, we found limited evidence of improvement in dietary intakes due to nutrition interventions in the context of cardiovascular disease prevention and management in rural communities. Fruit and/or vegetable intakes were the most frequently reported dietary intake outcomes, and most likely to be improved across the included studies. Included studies were generally not well reported, which may hinder replication by clinicians and consolidation of the evidence base by other researchers. Given the substantial burden of cardiovascular disease experienced by those living in rural areas of developed countries, additional high-quality nutrition research that acknowledges the complexities of rural health is required.

Informing telehealth service delivery for cardiovascular disease management: exploring the perceptions of rural health professionals.

Objective To explore the perceptions of rural health professionals who use telehealth services for cardiovascular health care, including the potential role of telehealth in enhancing services for this patient group. Methods Semi-structured interviews were conducted with ten rural health professionals across a range of disciplines, including medicine, nursing and allied health. All study participants were based in the same rural region in New South Wales, Australia. Results Participant responses emphasised the importance of including rural communities in ongoing dialogue to enhance telehealth services for cardiovascular care. Divergent expectations about the purpose of telehealth and unresolved technology issues were identified as factors to be addressed. Rural health professionals highlighted the importance of all stakeholders coming together to overcome barriers and enhance telehealth services in a collaborative manner. Conclusion This study contributes to an evolving understanding of how health professionals based in regional Australia experience telehealth services. Future telehealth research should proceed in collaboration with rural communities, supported by policy that actively facilitates the meaningful inclusion of rural stakeholders in telehealth dialogue. What is known about the topic? Telehealth is frequently discussed as a potential solution to overcome aspects of rural health, such as poor outcomes and limited access to services compared with metropolitan areas. In the context of telehealth and cardiovascular disease (CVD), research that focuses on rural communities is limited, particularly regarding the experiences of these communities with telehealth. What does this paper add? This paper offers insight into how telehealth is experienced by rural health professionals. The paper highlights divergent expectations of telehealth's purpose and unresolved technological issues as barriers to telehealth service delivery. It suggests telehealth services may be enhanced by collaborative approaches that engage multiple stakeholder groups. What are the implications for practitioners? The use and development of telehealth in rural communities requires a collaborative approach that considers the views of rural stakeholders in their specific contexts. To improve telehealth services for people living with CVD in rural communities, it is important that rural stakeholders have opportunities to engage with non-rural clinicians, telehealth developers and policy makers.

Fidelity and acceptability of a family-focused technology-based telehealth nutrition intervention for child weight management.

INTRODUCTION: Previous reviews of family-based interventions for childhood obesity treatment found that studies were of low methodological quality with inadequate details reported, especially related to intervention fidelity. The evaluation of fidelity is crucial to inform interpretation of the intervention outcomes. This study aimed to summarise intervention fidelity, participants' acceptability and satisfaction with a 12-week family-focused technology-based child nutrition and weight management intervention. METHODS: Families with children aged 4-11 years participated in a telehealth intervention with complementary components: website, Facebook group and text messages. Intervention fidelity was reported using National Institutes of Health Treatment Fidelity Framework. Delivery was measured using a dietitian-reported evaluation survey. Google Analytics and Bitly platform were used to objectively track data on frequency and pattern of intervention use. Participants' acceptability and satisfaction were measured using a process evaluation survey. RESULTS: Telehealth consultations delivered by trained dietitians had good adherence (≥83%) to the structured content. Process evaluation results indicated that parents (n = 30; mean age 41 years, 97% were female, body mass index 30 kg/m2) found the intervention components easy to use/understand (87-100%), the programme had improved their family/child eating habits (93%), and they wanted to continue using telehealth and the website, as well as recommending it to other parents (90-91%). DISCUSSION: In summary, a family-focused technology-based child nutrition and weight management intervention using telehealth, website, Facebook and SMS can be delivered by trained dietitians with good fidelity and attain high acceptability and satisfaction among families with primary-school-aged children in New South Wales, Australia.

Exploring core food accessibility in Tamworth, NSW, Australia.

INTRODUCTION: A lack of core food accessibility negatively affects diet quality, potentially increasing the prevalence of health risk factors such as obesity. The purpose of this study was to investigate core food access in an Australian regional center through the use of data visualization techniques. METHODS: Supermarkets were used as a proxy for core food accessibility and were identified and mapped by town region with a combination of Google Maps and Stata/IC 15.1 software. A statistical analysis comparing the demographics of each town region was also completed using Stata. RESULTS: The maps generated suggest that there may be a disparity in core food accessibility between town regions. The analysis of demographics demonstrated that one town region had a greater proportion of disadvantaged residents, with statistically significant variation between regions. CONCLUSION: Data visualization and analysis may be a useful tool for clinicians to communicate accessibility information experienced by local residents. This need not be limited to food accessibility and extended to health services.

Factors Associated with Effective Nutrition Interventions for Pregnant Indigenous Women: A Systematic Review.

INTRODUCTION: Indigenous people continue to experience health disparities relative to non-Indigenous populations. Interventions to improve nutrition during pregnancy in these groups may improve health outcomes for mothers and their infants. The effectiveness of existing nutrition intervention programs has not been reviewed previously. OBJECTIVE: The objective was to identify interventions targeting improving nutrition-related outcomes for pregnant Indigenous women residing in Organisation for Economic Co-operation and Development countries, and to identify positive factors contributing to successful programs. METHODS: Thirteen electronic databases were searched up until October 2015. Key words identified studies intervening to improve nutrition-related outcomes for pregnant Indigenous women. Two reviewers assessed articles for inclusion and study quality and extracted data. Only studies published in English were included. Data were summarized narratively. RESULTS: Abstracts and titles were screened (n=2,566) and 315 full texts were reviewed for eligibility. This review included 27 articles from 20 intervention programs from Australia, Canada, and the United States. The most prevalent measurable outcomes were birth weight (n=9) and breastfeeding initiation/duration (n=11). Programs with statistically significant results for these outcomes employed the following nutrition activities: individual counseling/education (n=8); delivery by senior Indigenous woman (n=2), peer counselor (n=3), or other Indigenous health worker (n=4); community-wide interventions (n=2); media campaigns (n=2); delivery by non-Indigenous health professional (n=3); and home visits (n=3). CONCLUSIONS: Heterogeneity of included studies made it challenging to make firm recommendations regarding program success. Authors of included studies recommended community consultation be included when designing studies and working with communities at all stages of the research process. Individualized counseling/education can contribute to successful program outcomes, as can the use of Indigenous workers to deliver program content. Limitations of some studies included a lack of details on interventions and the use of nonrandom control groups. Future studies should include detailed descriptions of intervention components and include appropriate evaluation protocols.

Validation of a Smartphone Image-Based Dietary Assessment Method for Pregnant Women.

Image-based dietary records could lower participant burden associated with traditional prospective methods of dietary assessment. They have been used in children, adolescents and adults, but have not been evaluated in pregnant women. The current study evaluated relative validity of the DietBytes image-based dietary assessment method for assessing energy and nutrient intakes. Pregnant women collected image-based dietary records (via a smartphone application) of all food, drinks and supplements consumed over three non-consecutive days. Intakes from the image-based method were compared to intakes collected from three 24-h recalls, taken on random days; once per week, in the weeks following the image-based record. Data were analyzed using nutrient analysis software. Agreement between methods was ascertained using Pearson correlations and Bland-Altman plots. Twenty-five women (27 recruited, one withdrew, one incomplete), median age 29 years, 15 primiparas, eight Aboriginal Australians, completed image-based records for analysis. Significant correlations between the two methods were observed for energy, macronutrients and fiber (r = 0.58-0.84, all p < 0.05), and for micronutrients both including (r = 0.47-0.94, all p < 0.05) and excluding (r = 0.40-0.85, all p < 0.05) supplements in the analysis. Bland-Altman plots confirmed acceptable agreement with no systematic bias. The DietBytes method demonstrated acceptable relative validity for assessment of nutrient intakes of pregnant women.

Contribution of university departments of rural health to rural health research: An analysis of outputs.

OBJECTIVE: To assess the research contribution of eleven University Departments of Rural Health (UDRH) which were established as a rural health workforce program in the late 1990s through analysis of peer-reviewed journal output. DESIGN AND SETTINGS: Descriptive study based on validated publications from publication output reported in annual key performance indicator (KPI) reports to the Commonwealth Department of Health, Australia. MAIN OUTCOME MEASURES: In addition to counts and the type of publications, articles were examined to assess fields of research, evidence of research collaboration, and potential for influencing policy. Funding acknowledgement was examined to provide insight into funding sources and research consultancies. RESULTS: Of the 182 peer-reviewed articles, UDRH staff members were the first and corresponding author for 45% (n = 82); most (69%, n = 126) were original research. Most publications examined included Australian data only (80%, n = 101). Over half (56%; n = 102) of the articles addressed rural health issues; Aboriginal health was the main subject in 14% (n = 26). Thirty-three articles (18%) discussed the policy implications of the research and only half (51%, n = 93) of the articles listed sources of funding. Number of authors per article ranged from 1-19, with a mean of 5 (SD = 3.2) authors per article, two-thirds of articles included authors from 2-5 universities/organisations but only 5% of articles included an author from more than one UDRH. CONCLUSIONS: Staff from UDRHs are regularly publishing peer-reviewed articles, and research productivity demonstrated cooperation with external partners. Better collaboration between UDRH staff and others may help increase the quality and value of Australian rural health research.
