Community-integrated Nutrition Education to Prevent Type 2 Diabetes in Peel

What this study is about

The goal of this clinical trial is to assess the effectiveness of an intervention that delivers nutrition education based on the Portfolio Diet on type-2 diabetes (T2D) risk factors among adults who are without chronic conditions, who have overweight and a high waist circumference plus one self-reported T2D risk factor. The main questions it aims to answer include: 1. What are the barriers and facilitators for effective implementation of the nutrition education intervention? 2. What is the effectiveness of the intervention on T2D risk factors? 3. What are implementation strategies for scaling up the intervention? Participants will participate in a 12-month lifestyle intervention comprised of nutrition education based on the Portfolio Diet that includes community gardening sessions. In addition, participants will take part in pre-implementation focus groups/interviews and post-implementation focus groups/interviews.
