Associations of relative fat mass, a new index of adiposity, with type-2 diabetes in the general population.

Background: Relative fat mass (RFM) is a novel sex-specific anthropometric equation (based on height and waist measurements) to estimate whole-body fat percentage.

Objective: To examine associations of RFM with incident type-2 diabetes (T2D), and to benchmark its performance against body-mass index (BMI), waist circumference (WC) and waist-to-hip ratio (WHR).

Methods: This prospective longitudinal study included data from three Dutch community-based cohorts free of baseline diabetes.
