Clinical Trial 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.

• Frailty

Intervention

Behavioral:
• Mobile 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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change From Baseline Mediterranean Diet (MED) Adherence Score at 3 Months	Alternative MED (aMED) score will be calculated using the Food Frequency Questionnaire (FFQ). aMED scores range from 0 (nonadherence) to 9 (perfect adherence)	baseline, 3 month
Primary	Change From Baseline HOMA-IR Score at 3 Months	Insulin 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.	baseline, 3 month
Secondary	Change From Baseline Mediterranean Diet Knowledge Score at 3 Months	MedD knowledge will be assessed using the Mediterranean Diet Nutrition Knowledge (MDNK) Questionnaire. The total scores range from 0 to 30. Higher score higher knowledge	baseline, 3 month
Secondary	Change From Baseline Positive Outcome Expectations Score at 3 Months	Questionnaire, 7 items rated on a 5-point scale (strongly agree 5; strongly disagree 1). Higher score more positive outcome expectations. The total scale ranges from 7 to 35	baseline, 3 month
Secondary	Change From Baseline Negative Outcome Expectations Score at 3 Months	Questionnaire, 6 items rated on a 5-point scale (strongly agree 5; strongly disagree 1). Higher score more negative outcome expectations. The total score ranges from 30 to 6	baseline, 3 month
Secondary	Change From Baseline Self-regulation Score at 3 Months	Questionnaire, 2 items rated on a 5-point scale (strongly agree 5; strongly disagree 1). Higher score more self-regulation. The total scale ranges from 10 to 2	baseline, 3 month
Secondary	Change From Baseline Self-Efficacy Score at 3 Months	Visual analog scale (VAS), 6 items using a 10-point scale. Higher values more self-efficacy. The total score ranges from O to 60	baseline, 3 month
Secondary	Change From Baseline Social Support Score at 3 Months	Questionnaire, 2 items rated on a 5-point scale (strongly agree 5; strongly disagree 1). Higher score more social support. The total score ranges from 10 to 2	baseline, 3 month
Secondary	Change From Baseline Physical Performance Measure at 3 Months	Short Physical Performance Battery (SPPB) is a composite measure assessing walking speed, standing balance, and sit-to-stand performance. The three tests are summed to give a total score, with a maximum of 12 and minimum of 0. Higher score higher function	baseline, 3 month
Secondary	Change From Baseline BMI at 3 Months	BMI in units	baseline, 3 month
