Emory: Researcher Finds Two High-risk Populations Show Differences in Mechanisms of Diabetes Development

Although both Pima Indians and Asian Indians are at high risk of developing type 2 diabetes, new research suggests the mechanisms that cause the disorder to develop may differ between the two populations. The findings were recently published in Diabetes Metabolism Research and Reviews. Dr. Lisa R. Staimez, assistant professor at the Emory Rollins School of Public Health, is first author of the study.

“For the present study, our objective was to examine diabetes pathophysiology across a varied landscape of anthropometry. We examined population‐based data from Pima Indians and Asian Indians, two populations that are both considered high‐risk populations for diabetes development,” says Dr. Staimez.

The study found that Pima Indians were three times more insulin resistant than Asians, whereas Asian Indians secreted nearly three times less insulin.

This observation suggests that there were divergent pathways in developing type 2 diabetes in the early natural history of the disease, notes Dr. Staimez.

Dr. K.M. Venkat Narayan, professor of global health at Rollins School of Public Health, is senior author of the paper. Other authors include Dr. Mohammed K. Ali from the Rollins School of Public Health, Dr. Robert L. Hanson from the National Institutes of Health (NIH), and Dr. Mohan Deepa and Dr. Viswanathan Mohan from the Madras Diabetes Research Foundation in Chennai, India.
