Insulin resistance, central obesity, and risk of colorectal adenomas

Increasing evidence supports insulin resistance (IR) as the underpinning of the obesity‐colorectal neoplasia link. The homeostasis model assessment‐IR (HOMA‐IR) is a widely accepted index of evolving hyperinsulinemia and early IR. Studies of the relation between HOMA‐IR and colorectal adenomas are limited. Therefore, the authors sought to determine the associations of HOMA‐IR and central obesity (waist to hip ratio [WHR]) with risk of colorectal adenomas in a screening colonoscopy‐based study.
