ClinConnect Summary

This clinical trial is studying whether a mobile phone app called PortionSize Ed can help people who have recently had a stroke and also have prediabetes or type 2 diabetes improve their eating habits. The app focuses on encouraging a Mediterranean-style diet, which is known to be heart-healthy and may reduce the chance of having another stroke. The study wants to see if the app is easy to use, if it helps people eat healthier, and if it can improve important health measures like blood sugar, cholesterol, blood pressure, and body fat.

Adults aged 30 to 65 who have had a stroke within the past two weeks and have prediabetes or type 2 diabetes may be eligible to join. Participants must be medically stable, able to eat regular foods, and comfortable using a smartphone (a phone can be provided if needed). The study lasts 12 weeks, during which half the participants will use the full app with extra support like weekly reminders, educational videos, and virtual meetings with a dietitian. The other half will use a simpler version of the app without those extras. Everyone will continue their regular stroke care. Health checks and surveys will be done at the start and end of the study to see how well the app works. This trial aims to find new ways to support stroke survivors in managing their health through better diet.
