NCT03342274

Brief Summary

This study will examine whether an adapted version of \]he Diabetes Prevention Program (DPP) can be effective when delivered by community health workers (CHWs) in a poor urban community in South Africa. We will randomize existing groups that are part of an non-governmental organization's (NGO) chronic disease management program (anticipated cluster N = 54; anticipated individual N=540), to receive either the program or usual care (wait-list). The primary outcome analysis will compare percentage of baseline weight loss at Y1 between the program and usual care; however, after Y1 usual care participants will also receive the program and both groups will be followed for another year.
