Four-year HbA1c and LDL-cholesterol trajectories among individuals with mental disorders and newly developed type 2 diabetes.

The impact of different types of mental disorders on long-term glycemic and lipid trajectories following newly diagnosed type 2 diabetes (T2D) remains unknown. We used real-world clinical data in a population-based cohort to fill this knowledge gap. We found that individuals with new T2D and preexisting personality, anxiety, unipolar depression, or psychotic disorder had higher mean HbA1c levels over 4 years following the onset of T2D, whereas no differences were found regarding LDL-C levels. This knowledge should be considered in the management of T2D in these vulnerable groups.
