Working to prevent and treat obesity and diabetes with transformative research conducted by top scientists in the field.

Our Research

DORI brings together a diverse group of researchers spanning over 15 divisions and departments across the University of Southern California to bring new discoveries in obesity and diabetes prevention and treatment.

Education & Enrichment

Located in the heart of Los Angeles, we support diabetes & obesity research in underserved populations disproportionately affected by these diseases. Our goal is to reduce the burden of obesity and diabetes in our community.

The State of Obesity & Diabetes

Worldwide
The number of people with diabetes rose from 108 million in 1980 to 422 million in 2014.
In 2019, 1.9 billion adults worldwide were overweight, with 650 million obese; meaning 39% of adults were overweight and 13% were obese globally.
Between 2000 and 2016, there was a 5% increase in premature mortality from diabetes.
In 2017, over 4 million people died as a result of being overweight or obese, according to the global burden of disease.
Diabetes is a major cause of blindness, kidney failure, heart attacks, stroke & lower limb amputation.
From 1975 to 2016, the prevalence of overweight or obese children and adolescents aged 5–19 years increased more than four-fold from 4% to 18% globally.
In 2016, an estimated 1.6 million deaths were directly caused by diabetes. Another 2.2 million deaths were attributable to high blood glucose in 2012.
