Metabolic and Inflammatory Links to Depression in Youth With Diabetes

Diabetes Care | October 04, 2012

Hood KK et al. – The objectives of this study were to provide preliminary evidence that this at-risk status for depression is associated with metabolic and inflammatory markers and to inform future, more stringent examinations of the directionality of these associations. The data suggest that depression reported by youth with diabetes is partially associated with metabolic abnormalities and systemic inflammation.


  • Data from SEARCH for Diabetes in Youth Study Group (SEARCH), an observational study of U.S. children diagnosed with diabetes at <20 years of age, were used for these analyses.
  • SEARCH participants were drawn from four geographically defined populations in Ohio, Washington, South Carolina, and Colorado; health plan enrollees in Hawaii and California; and Indian Health Service beneficiaries from four Native American populations.
  • Participants were 2,359 youth with diabetes from the 2001 prevalent and 2002–2004 incident SEARCH cohorts.
  • Depression was measured with the Center for Epidemiologic Studies Depression scale.
  • Eight metabolic and inflammatory markers were measured: adiponectin, leptin, C-reactive protein, serum amyloid A, apolipoprotein B (apoB), lipoprotein A, interleukin-6, and LDL.


  • Six of eight markers were significantly (P < 0.006) associated with depression in youth with diabetes in bivariate analyses.
  • In general, higher levels of depression were associated with indicators of worse metabolic or inflammatory functioning.
  • In regression models stratified by diabetes type and accounting for demographic and clinical characteristics, only higher levels of apoB remained associated with higher levels of depression in youth with type 1 diabetes.
