Caffeine Consumption and Mortality in Diabetes

Previous studies suggested an inverse relationship between coffee consumption and mortality in the general population. Furthermore, an inverse association between coffee consumption and serum biomarkers of inflammation and insulin resistance has been described. Prospective studies showed that coffee consumption might be associated with reduction in the incidence of type 2 diabetes. Although caffeine consumption appears to be associated with a decreased risk of developing type 2 diabetes, the relationship between caffeine consumption and mortality in patients with diabetes remains uncertain. The current analysis aimed to assess the effects of caffeine consumption and caffeine source on all-cause, cardiovascular and cancer mortality among patients with diabetes.
