Glycemia, Insulin Resistance, Insulin Secretion, and Risk of Depressive Symptoms in Middle Age
ADA: December 10, 2012
OBJECTIVE The extent to which abnormal glucose metabolism increases the risk of depression remains unclear. In this study, we investigated prospective associations of levels of fasting glucose and fasting insulin and indices of insulin resistance and secretion with subsequent new-onset depressive symptoms (DepS).
RESEARCH DESIGN AND METHODS In this prospective cohort study of 3,145 adults from the Whitehall II Study (23.5% women, age 60.6 ± 5.9 years), baseline examination included fasting glucose and insulin level, the homeostasis model assessment of insulin resistance (HOMA2-%IR), and the homeostasis model assessment of β-cell insulin secretion (HOMA2-%B). DepS (Center for Epidemiologic Studies Depression Scale ≥16 or use of antidepressive drugs) were assessed at baseline and at 5-year follow-up. Read More
