AbstractOBJECTIVE—To determine whether the association between depressive symptoms and glycemic control is mediated by blood glucose monitoring (BGM). RESEARCH DESIGN AND METHODS—A total of 276 adolescents with type 1 diabetes (mean age ± SD, 15.6 ± 1.4 years) completed a measure of depressive symptoms. Sociodemographic and family characteristics were obtained from caregivers. BGM frequency and glycemic control were obtained at a clinic visit. RESULTS—Separate regression analyses revealed that depressive symptoms were associated with lower BGM frequency (B = −0.03; P = 0.04) and higher A1C (B = 0.03; P = 0.05) and that lower BGM frequency was associated with higher A1C (B = −0.39; P < 0.001). With depressive symptoms and BGM frequency included together, only BGM frequency was associated with A1C and depressive symptoms became nonsignificant (B = 0.02; P = 0.19). The Sobel test was significant (Z = 1.96; P < 0.05) and showed that 38% of the depression-A1C link can be explained by BGM. CONCLUSIONS—BGM is a mediator between depressive symptoms and glycemic control in adolescents with type 1 diabetes.
