Item Dietary patterns influencing the human colonic microbiota from infancy to centenarian age: a narrative review(Frontiers Media S A, 2025-06-04) Geniselli da Silva V; Roy NC; Smith NW; Wall C; Mullaney JA; McNabb WC; Benítez-Páez AOur dietary choices not only affect our body but also shape the microbial community inhabiting our large intestine. The colonic microbiota strongly influences our physiology, playing a crucial role in both disease prevention and development. Hence, dietary strategies to modulate colonic microbes have gained notable attention. However, most diet-colonic microbiota research has focused on adults, often neglecting other key life stages, such as infancy and older adulthood. In this narrative review, we explore the impact of various dietary patterns on the colonic microbiota from early infancy to centenarian age, aiming to identify age-specific diets promoting health and well-being by nourishing the microbiota. Diversified diets rich in fruits, vegetables, and whole grains, along with daily consumption of fermented foods, and moderate amounts of fish and lean meats (two to four times a week), increase colonic microbial diversity, the abundance of saccharolytic taxa, and the production of beneficial microbial metabolites. Most of the current knowledge of diet-microbiota interactions is limited to studies using fecal samples as a proxy. Future directions in colonic microbiota research include personalized in silico simulations to predict the impact of diets on colonic microbes. Complementary to traditional methodologies, modeling has the potential to reduce the costs of colonic microbiota investigations, accelerate our understanding of diet-microbiota interactions, and contribute to the advancement of personalized nutrition across various life stages.Item Using ‘Health’ to Promote Older Adults’ Digital Health Literacy(European Society of Medicine, 2024-07-01) Lockhart C; Hunter IAim: This project explored requirements for digital learning to support digital health literacy of older adults within a rural region. Method: A qualitative study with purposeful sampling and thematic analysis of data. Interviews were held with ten digital educators and seven older adults (four with low vision) living and/or working in rural New Zealand. Results: All participants recognised the importance of trust and having the right people to provide support and foster positive engagement with digital technologies. The digital educators recognised a missed opportunity to engage older adults using health as a topic for digital learning. Conclusion: A positive experience with learning to use digital technologies is necessary to facilitate digital health literacy for older adults. Digital educators want access to reputable resources to promote health websites; many don’t know these exist. A wide range of digital literacy learning services exist which need to be better promoted in hard copy and online. The authors recommend building on older adults’ existing relationships, engaging with community groups, providing pop-up sessions, and running events to increase digital technological knowledge and engage with health information online. The key is utilising the right people to support the older adult with opportunities for digital skills uptakeItem Enabling Rural Telehealth for Older Adults in Underserved Rural Communities: Focus Group Study(JMIR Publications, 2022-11-04) Hunter I; Lockhart C; Rao V; Tootell B; Wong SBackground: Telehealth is often suggested to improve access to health care and has had significant publicity worldwide during the COVID-19 pandemic. However, limited studies have examined the telehealth needs of underserved populations such as rural communities. Objective: This study aims to investigate enablers for telehealth use in underserved rural populations to improve access to health care for rural older adults. Methods: In total, 7 focus group discussions and 13 individual interviews were held across 4 diverse underserved rural communities. A total of 98 adults aged ≥55 years participated. The participants were asked whether they had used telehealth, how they saw their community’s health service needs evolving, how telehealth might help provide these services, and how they perceived barriers to and enablers of telehealth for older adults in rural communities. Focus group transcripts were thematically analyzed. Results: The term telehealth was not initially understood by many participants and required an explanation. Those who had used telehealth reported positive experiences (time and cost savings) and were likely to use telehealth again. A total of 2 main themes were identified through an equity lens. The first theme was trust, with 3 subthemes—trust in the telehealth technology, trust in the user (consumer and health provider), and trust in the health system. Having access to reliable and affordable internet connectivity and digital devices was a key enabler for telehealth use. Most rural areas had intermittent and unreliable internet connectivity. Another key enabler is easy access to user support. Trust in the health system focused on waiting times, lack of and/or delayed communication and coordination, and cost. The second theme was choice, with 3 subthemes—health service access, consultation type, and telehealth deployment. Access to health services through telehealth needs to be culturally appropriate and enable access to currently limited or absent services such as mental health and specialist services. Accessing specialist care through telehealth was extremely popular, although some participants preferred to be seen in person. A major enabler for telehealth was telehealth deployment by a fixed community hub or on a mobile bus, with support available, particularly when combined with non–health-related services such as internet banking. Conclusions: Overall, participants were keen on the idea of telehealth. Several barriers and enablers were identified, particularly trust and choice. The term telehealth is not well understood. The unreliable and expensive connectivity options available to rural communities have limited telehealth experience to phone or patient portal use for those with connectivity. Having the opportunity to try telehealth, particularly by using video, would increase the understanding and acceptance of telehealth. This study highlights that local rural communities need to be involved in designing telehealth services within their communities.
