Older adults with pre-frailty and frailty face vulnerability to malnutrition, but often lack access to tailored and credible nutrition education, researcher Adeline Lau from Flinders University's Caring Futures Institute said on July 31. Lau emphasized the importance of designing online nutrition resources that are personalized, credible, and accessible across diverse learning needs.
Lau said, "They value online nutrition education but they require resources that are personalized, credible and accessible across diverse learning needs. Therefore, their voices need to be embedded in resource design and to provide future directions for refining the current online nutrition resource."
The research team examined the experiences of community-dwelling older adults with pre-frailty and frailty as they engaged with an online nutrition educational resource aimed at helping people prevent and manage frailty. According to Lau, "This study highlights the deeper, experiential factors influencing user engagement rather than focusing on usability or digital literacy barriers." She added that participants' personal contexts influenced both their motivation to learn and how relevant they found the content.
Participants used the resource over two to four weeks. Their engagement was shaped by how trustworthy they considered it to be and whether it provided new information. Many valued opportunities for personalization in their learning experience, integrating knowledge into daily life, validating experiences through self-directed exploration, multimodal formats, and seeing lived experience reflected in educational tools.
Lau said these insights expand understanding of digital engagement: "These insights expand our current understanding of digital engagement by showing that successful online nutrition education for older adults depends not only on usability but also on fostering empowerment, trust and personal meaning." Some participants reported positive dietary changes after using the resource; others described reflective learning even without immediate behavior change.
The researchers concluded that embedding consumer voices throughout digital health intervention design is crucial. Lau said, "This study demonstrates the importance of embedding older adults' voices throughout the design of digital health interventions, to ensure they are acceptable, relevant and impactful." She added that consumer-informed online nutrition education may support autonomy, empowerment, and healthy aging.
