 The GHP CHANGE community -based intervention aims to promote positive behaviors and focus more on what creates health, rather than what prevents sickness. It is built on the foundations of social support, assessing whether people going through similar challenges will support each other, work together to identify and address barriers to success, and motivate each other to move forward. In this program we test for the impact of promotion of healthy lifestyle behaviors through peer motivation on blood pressure, physical activity, eating behavior, weight, and smoking.
