Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The main goals are to:
* Test if the app is easy to use and acceptable to participants.
* See whether the app helps people follow a healthier diet.
* Look at changes in health indicators like blood sugar, cholesterol, blood pressure, and body fat.
Design and Outcome:
This is a randomized controlled pilot study that will involve 40 participants. All participants will be recruited from Queen's Medical Center after a recent stroke and will be randomly assigned to one of two groups:
Intervention Group: Uses the full PortionSize Ed app, gets weekly reminders and educational videos, and has 3 sessions with a registered dietitian (RDN) over 12 weeks.
Control Group: Uses a basic version of the app without feedback or RDN support, and receives usual care for stroke recovery.
All participants will continue to receive standard care from Queen's, including the My Stroke Recovery Guide. The study lasts 12 weeks, with visits at the beginning and end to collect health data and feedback on the app.
Schedule and Type of Evaluations/Interventions:
Participants will complete the following:
Baseline and Week 12 Visits: In-person assessments for blood sugar (HbA1c), cholesterol, blood pressure, height, weight, and body composition (using DXA, BIA, and 3D imaging), as well as surveys about their diet and activity levels.
Intervention Group Only:
* Three virtual counseling sessions with a registered dietitian (Week 1, 6, 12)
* Weekly nutrition goal tracking and texting with the dietitian
* Watching short educational videos through the app
* Receiving app-based feedback on how well their diet follows Mediterranean Diet recommendations
Duration of Study: The study will last 12 weeks for each participant, with an optional long-term follow-up using medical records.
Sample Size and Population: The study will include 40 adults, ages 30 to 65, who:
* Recently experienced a stroke
* Have a history of prediabetes or type 2 diabetes
* Are medically stable and able to use a smartphone (or willing to use a study-provided iPhone)
* People will be excluded if they have severe swallowing issues, cognitive problems, or dietary needs that would make it hard to follow a Mediterranean-style diet.
