Depressive Symptoms, Antidepressant Medication Use, and Insulin Resistance The PPP-Botnia Study

Summary, in English

OBJECTIVE-Although insulin resistance (IR) may underlie associations between depressive symptoms and diabetes, previous findings have been contradictory. We examined whether depressive symptoms associate with IR and insulin secretion, and, additionally, whether antidepressant medication use may modulate such associations. RESEARCH DESIGN AND METHODS-A total of 4,419 individuals underwent an oral glucose tolerance test (OGTT). Participants with previously or newly diagnosed diabetes are excluded from this sample. The homeostasis model assessment of IR (HOMA-IR) and corrected insulin response (CIR) were calculated. Depressive symptoms and antidepressant medication use were self-reported. RESULTS-After controlling for confounding factors, depressive symptoms were associated with higher fasting and 30-mM insulin during the OGTT and higher HOMA-IR but not CIR. Antidepressant medication use failed to modify these associations. CONCLUSIONS-Depressive symptoms are associated with IR but not with changes in insulin response when corrected for IR in individuals without previously or newly diagnosed diabetes.
