(P30-025-24) A Study Protocol for Voice4Healthy-Eating: Using Smart Speaker-Based Voice Assistant for Healthy Eating in Older Adults

Objectives: The significance of maintaining healthy eating among older adults cannot be overstated, as it plays a pivotal role in preventing chronic conditions and mitigating healthcare costs. Nearly 95% of older adults aged 65 or older have at least one chronic condition, and nearly 80% have two or more. Aside from exerting a profound toll on health and overall well-being, multiple chronic conditions (MCCs) constitute a staggering 90% of Medicare expenditures. Numerous studies have consistently demonstrated that embracing a healthy eating pattern not only diminishes the risk of chronic conditions but also aids in maintaining a healthy weight and promoting active, independent living among older adults. However, refining maintainable and straightforward interventions to bolster adherence to dietary guidelines remains paramount in chronic disease self-management. The objective is to evaluate the feasibility and preliminary effects of smart speaker-assisted dietary guidelines on biomarkers of general health in older adults with MCCs.

Methods: We propose a pilot study using multiple data collection methods incorporating qualitative interviews, post-survey, and feasibility testing. Participants will be recruited through flyers, electronic newsletters, outpatient clinics, and word of mouth. The enrollment will include 20 older adults who have a diagnosis of more than two of the top five chronic diseases and have internet access in the subject’s residence. Subjects will participate in a 3-month program focusing on using MyPlate dietary guidelines enabled by smart speaker. At the baseline visit, participants will receive hands-on training on how to use MyPlate through the smart speaker. Participants will visit the study site to conduct a post-survey and qualitative interview at baseline and 3-months. Weight, blood pressure, blood glucose, lipid profile will be measured at baseline and 3-months.

Results: N/A

Conclusions: Understanding older adults’ perceptions, acceptability, and feasibility of smart speakers will inform the translation of voice-assisted smart speakers as a clinically relevant tool for enhancing adherence to healthy eating guidelines.
