1. Changes in Body Mass Index (BMI): Track changes in average BMI or the proportion of individuals classified as overweight or obese within the target population. Obesity is a significant risk factor for developing type 2 diabetes, and a reduction in BMI indicates improvements in weight management and overall health.

2. Blood Glucose Control: Measure average blood glucose levels or the proportion of individuals with well-controlled blood glucose within the target population. Improved blood glucose control indicates better management of diabetes risk factors and reduced progression to diabetes.

3. Program Engagement and Participation: Evaluate the level of engagement and participation in the prevention program, including attendance rates for educational sessions, participation in physical activity programs, and utilization of support resources. Higher engagement indicates increased program reach and potential effectiveness.
