Key result
Depressive symptoms show no association with 3-year metabolic control in African Americans with T2D.
Why the study?
The longitudinal relationship between depressive symptoms and glycemic control has not been well examined among African Americans with type 2 diabetes.
Is there a longitudinal relationship between changes in depressive symptoms and changes in metabolic control in African Americans with type 2 diabetes?
Cohort (n=183)
Is there a longitudinal relationship between changes in depressive symptoms and changes in metabolic control in African Americans with type 2 diabetes?
In a 3-year longitudinal study of African Americans with type 2 diabetes, changes in depressive symptoms were not significantly associated with changes in metabolic control, though this may be due to limited statistical power.

Depressive symptoms linked to poorer metabolic markers in African American T2D; leaves open causality and whether screening alters outcomes.
OBJECTIVE: It is established that individuals with diabetes have high rates of depression, but the longitudinal relationship between depression and glycemic control has not been well examined, particularly among African Americans. The objective of this study was to evaluate the longitudinal relationship between depressive symptoms and metabolic control. METHOD: We conducted an earlier cross-sectional study that demonstrated marginal and significant associations between depressive symptoms (using the Center for Epidemiologic Studies Depression Scale [CES-D]) and metabolic control (HbA1c, lipids, blood pressure) among 183 African Americans with type 2 diabetes. In this report, we present data on these individuals, followed for three years, and examine the relationship between change in depressive symptoms and change in metabolic control over that time period. RESULTS: Results showed that that there were no statistically significant associations between baseline or change in depressive symptoms and metabolic control over three years. Limited statistical power may explain this negative finding. CONCLUSIONS: This study provides insight into the relationship between depression and metabolic control. Prospective observational studies are needed to further evaluate this relationship.

Gary‐Webb et al. (2005) conducted a cohort in Type 2 diabetes (n=183). Depressive symptoms was evaluated on Metabolic control (HbA1c, lipids, blood pressure). Baseline or change in depressive symptoms showed no statistically significant associations with metabolic control over 3 years among African Americans with type 2 diabetes.
