Age of obesity onset, cumulative obesity exposure over early adulthood and risk of type 2 diabetes

The aim of this study was to examine the associations between BMI trajectories, age of onset of obesity and obese-years (a product of degree and duration of obesity) over early adulthood and subsequent risk of type 2 diabetes.
