Steinarsson AO, et al. - This longitudinal observational study was performed to assess the clinical characteristics at type 2 diabetes diagnosis and the broad trajectories in cardiometabolic risk factors over the initial years following diagnosis in relation to age at diagnosis. Compared with individuals who develop diabetes later in life, those who developed type 2 diabetes at a younger age were more often obese, showed a more adverse lipid profile, had higher HbA1_c and a faster deterioration in glycaemic control. These differences largely remained for several years after diagnosis. Thus, findings supported the notion that early-onset type 2 diabetes could be a more pathogenic condition than the late-onset disease.
