Community health representatives (CHRs) in American Indian and Alaska Native communities play a critical role in diabetes prevention and care. As respected community members, CHRs possess both cultural knowledge and health training, allowing them to bridge cultural understandings with conventional medicine. With additional diabetes-specific training, CHRs can help educate community members as well as serve as valuable members of health care teams. The CHR model draws theoretical support from social support and social influence theories, with CHRs providing emotional, instrumental, informational and appraisal support that helps community members manage diabetes and make healthy choices.
