Brief summary

This will be a pilot clinical trial to evaluate preliminary efficacy of a newly designed mobile intervention designed to support healthy eating in old people. The main scientific premise of this project is that mobile approaches are feasible for behavioral and metabolic improvements in the population of people 65+ with mild-to-moderate frailty. Specific Aim of this project is to describe feasibility, acceptability and initial efficacy of the newly designed mobile intervention in a pilot RCT. The pilot RCT, comparing usual care to usual care plus mobile intervention, will provide data on the sensitivity of outcome measures and estimated effect size to inform a larger RCT. Primary outcomes for the pilot RCT will include change in adherence to Mediterranean diet (MedD) score, change in insulin sensitivity measures, feasibility and acceptability. Secondary outcomes include MedD knowledge, self-efficacy, outcome expectation, self-regulation, social support, platform use and anthropometric and functional measures.

Interventions

BEHAVIORALMobile app

The app sends reminder 'push' notifications to complete weekly surveys. The survey is a series of questions about foods and drinks participants had in the last week. Once the weekly survey is completed the app generates a personalized weekly report showing foods we encourage participants to eat more of, eat less of, or keep eating the same amount of. The app will also show menu recommendations for breakfast, lunch, dinner, and snacks that will help participants to eat healthier. Finally, the app also has a feature that allows chatting with the research team by sending and receiving in-app texts.

Design outcomes

Primary

MeasureTime frameDescription
Change From Baseline Mediterranean Diet (MED) Adherence Score at 3 Monthsbaseline, 3 monthAlternative MED (aMED) score will be calculated using the Food Frequency Questionnaire (FFQ). aMED scores range from 0 (nonadherence) to 9 (perfect adherence)
Change From Baseline HOMA-IR Score at 3 Monthsbaseline, 3 monthInsulin resistance scores, homeostatic model (HOMA-IR) was calculated with the following formula: fasting plasma glucose (in mmol/L) X fasting plasma insulin (in lU/mL) divided by 22.5. Higher score indicates worse insulin resistance. Typically, a HOMA-IR value of less than 1 is considered normal, indicating low insulin resistance.
