Are insulin resistance, impaired fasting glucose and impaired glucose tolerance all equally strongly related to age?

Background Insulin resistance (IR) has been considered an underlying cause of impaired glucose tolerance (IGT) and impaired fasting glucose (IFG). Whether IR increases with age has been debated. We investigated the age‐associated deterioration in the homeostasis model assessment (HOMA) of IR and in glucose metabolism. Methods Ten (nine including women) European studies contributed data on 6314 men and 6393 women aged 30–88 years. The cohort‐ and...
