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.

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.
