Summary

Small Steps for Big Changes (SSBC) is a diet and exercise counselling program that significantly reduces the risk of developing Type 2 Diabetes (T2D). In partnership with YMCAs in Canada spanning 8 provinces, the aim of this study is to scale-up program delivery and evaluate the implementation and effectiveness of SSBC. To evaluate implementation, the number of staff trained/patients enrolled, attendance, sessions delivered as planned, delivery costs, and number of sites continuing to deliver the program will be examined. To evaluate program effectiveness, changes in patient health (e.g., T2D status, blood glucose, weight, exercise, diet) will be measured over 2 years following program completion.

Detailed description

In partnership with YMCAs in Canada spanning 8 provinces (overseeing 44 distinct community facilities/sites), the investigators will adapt and deliver our evidence-based diabetes prevention program, Small Steps for Big Changes. The purpose of this project is to evaluate the implementation and effectiveness of SSBC across diverse urban communities. Specifically, the investigators aim to: 1. Evaluate the implementation and sustainability of the program by examining the number of staff trained/patients enrolled, attendance, sessions delivered as planned, delivery costs, and number of sites continuing to deliver the program. 2. Examine clinical-effectiveness of the program on: T2D status (self-report and HbA1c; primary outcomes), cardiorespiratory fitness, anthropometric (weight, waist circumference, resting heart rate), health behaviours (exercise, diet). 3. Examine cost-effectiveness of the program on: healthcare resource utilization, and health-related quality of life (secondary outcomes). Research Design: A hybrid type 2 implementation-effectiveness study design (Curran et al., 2012) with multi/mixed methods will be used to evaluate the implementation and effectiveness of SSBC. SSBC program: SSBC will be administered and facilitated by the community facility trainers at YMCA locations. SSBC consists of 6 sessions delivered over 4 consecutive weeks, with each session comprising brief (20-30 mins) counselling that support participants self-regulatory skills to promote independence and long-term adherence to healthy dietary behaviours and regular exercise, followed by 20-30 mins of supervised aerobic exercise.

BEHAVIORAL	Behavioural: Small Steps for Big Changes Diabetes Prevention Program	The 4-week behaviour change program will introduce participants to a regular healthy lifestyle including exercise and dietary changes for reducing sugar intake, reducing refined/processed carbohydrate intake, increasing vegetable consumption. The 4-week program will include six supervised exercise sessions and three exercise sessions performed independently (e.g., at home or outside of the YMCA). The supervised session will include brief behavioural counselling sessions that teach participants self-regulatory skills to promote independence and long-term adherence to exercising and dietary changes.
