Purpose: Patients with Type 2 diabetes (T2D) have increased risk of depression and anxiety. Evidence suggests that a heightened inflammatory state may contribute to this association. Females experience more depression and higher inflammation levels than males. This study compared associations of serum high-sensitivity C-reactive protein (hs-CRP) levels with symptoms of depression and anxiety between men and women with Type 2 diabetes mellitus (T2DM). Method: Cross-sectional data including demographic and disease characteristics, symptoms of depression and anxiety, clinical data, and laboratory values were collected from 392 patients with T2DM recruited from a general hospital in Shandong Province, China. We evaluated associations between serum hs-CRP level and symptoms of depression and anxiety in males and females separately using multiple linear regressions and chi(2) tests for trend. Results: Sex moderated the association between serum hs-CRP level and symptoms of depression (B = .112 [SE = 0.049]; p = .022) and anxiety (B = .137 [SE = 0.053]; p = .011). Among females, hs-CRP level was positively associated with depression (B = .034, 95% confidence interval [CI] = [.006, .061]; p = .016, false discovery rate [FDR]-adjusted p = .020) and anxiety (B = .041, 95% CI [.011, .071], p = .007, FDR-adjusted p = .007). Positive trends indicated a higher prevalence of clinically significant symptoms of depression and anxiety in higher serum hs-CRP categories in females. No associations were found in males. Conclusion: Findings demonstrate that associations between serum hs-CRP level and symptoms of depression and anxiety in patients with T2D are sex-specific, with only females demonstrating a significant positive association.
