Older Adults’ Engagement in Technology‐Mediated Self‐Monitoring of Diet: A Mixed‐Method Study

PURPOSE: This feasibility study explored older adults’ use of a nutrition app called Appetitus (https://apps.apple.com/us/app/appetitt/id1001936854?ign‐mpt=uo%3D2; https://play.google.com/store/apps/details?id=no.nr.appetitt&hl=e) and addressed their engagement in technology‐mediated self‐monitoring of diet. Undernutrition is a significant challenge among older adults and is associated with poorer health experiences. Digital health for self‐monitoring of diet has the potential to increase awareness of personal nutrition, and the scarcity of research reporting older adults’ ability and willingness to engage in technology‐mediated dietary self‐monitoring warranted this study. DESIGN AND METHODS: An explorative mixed‐methods design combining descriptive analysis of log data with qualitative analysis of interviews with Appetitus users was implemented. FINDINGS: Twenty‐five older adults self‐monitored their diet using Appetitus over an 8‐week trial period. Eighty percent of the participants used the app regularly in the trial period. The most engaged users recorded their food consumption daily for 8 weeks. Personal interest in nutrition and commitment to the project facilitated regular use of Appetitus. Poor health and the perception that using a nutrition app lacked personal relevance contributed to irregular self‐monitoring. For inexperienced technology users, participation in this project became a springboard to using tablet technology and the Internet beyond the Appetitus app. CONCLUSIONS: The majority of the participants regularly used Appetitus for self‐monitoring of diet; they found the tablet technology and Appetitus app easy to use. CLINICAL RELEVANCE: Older adults are able and willing to use self‐monitoring tools. Nutrition apps can empower older adults to make better informed decisions about their diet. Patients’ self‐monitoring can provide valuable and detailed health‐related information to healthcare professionals and mediate patient‐centered care practices.
