Lancet Healthy Longevity study yesterday found that metformin—a common, generic type 2 diabetes medication used to manage blood sugar levels—is associated with significantly lower COVID-19 death risk in women, but not in men. Severe COVID-19 outcomes for people with diabetes have been widely observed, including greater risk of intensive care unit admission, intubation for mechanical ventilation, and death, possibly related to less effective glycemic, or blood sugar, control in these patients. This retrospective cohort study of 6,256 people with type 2 diabetes or obesity hospitalized for COVID-19 from Jan 1 to Jun 7 was a collaboration between the University of Minnesota Medical School and UnitedHealth Group (UHG)—a for-profit managed healthcare company based in Minnesota.
