Previous studies have suggested an association between coffee consumption
and a reduced risk of diabetes. Tuomilehto and colleagues conducted a prospective
study of Finnish adults to further investigate this purported link. After
adjusting for potential confounders including age, body mass index, physical
activity, alcohol use, and smoking status, they found a significant inverse
and graded association between daily coffee consumption and risk of type 2
diabetes during a mean follow-up of 12 years.
