New estimates predict more than 1.3 billion people worldwide will have diabetes by 2050, up from about 529 million in 2021, according to research published in The Lancet.  [Beckers Clinical Leadership & Infection Control}

"Diabetes will be a defining disease of this century," journal editors wrote in an accompanying editorial on the findings. "How the health community deals with diabetes in the next two decades will shape population health and life expectancy for the next 80 years."

The surge is expected to be driven by type 2 diabetes, which is largely driven by the prevalence of obesity. In the editorial, researchers pointed to structural racism and geographical inequity as drivers of diabetes, underscoring the importance of social determinants of health. 

"Addressing structural racism must become a core component of preventive strategies and health promotion — areas that invariably receive too little investment," the editorial said.
