Diabetes, depressive symptoms, and inflammation in older adults: Results from the Health, Aging, and Body Composition Study

These findings provide evidence that inflammation is associated with T2DM and elevated depressive symptoms. Participants with T2DM + DEP demonstrated the highest IL-6 levels compared to all other groups. Greater CRP levels were also observed in T2DM, but not elevated depressive symptoms, which may suggest that differential associations between T2DM and depressive symptoms exist for various inflammatory markers. Further investigation into these associations could aid in understanding the biological pathways underlying both T2DM and depressive symptoms.
