Takeaway

Why this matters

  • Findings highlight the need for effective chronic disease management in patients with diabetes, particularly in specialist care settings.

Study design

  • UK researchers conducted a meta-analysis of 44 studies (4 for T1D, 37 for T2D and 3 for both T1D and T2D), identified through a literature search across electronic databases.

  • Funding: None.

Key results

  • Compared with individuals without diabetes, the prevalence of depression was significantly higher in patients with (OR; 95% CI):

    • T1D (22% vs 13%; 2.10; 1.23-3.52; P<.001; I2, 78.9%); and

    • T2D (19% vs 11%; 1.76; 1.55-2.01; P=.005; I2, 89.6%).

  • The prevalence of depression was significantly higher in patients with diabetes in studies carried out in (OR; 95% CI):

    • specialist care (36%; 3.14; 2.12-4.63; P<.001; I2, 89.7%) vs those in community or primary care (12%; 1.51; 1.35-1.70; P<.001; I2, 84.8%); and

    • low- and middle-income countries (2.58; 1.91-3.50; I2, 91.5%) vs countries with high income economies (1.59; 1.39-1.82; I2, 87.5%).

Limitations

  • Heterogeneity among studies.

  • The study did not analyse the influence of other comorbidities on the association between diabetes and depression.
