Abstract
Objective
To provide an estimate of the effect of interventions on comorbid depressive disorder (MDD) or subthreshold depression in type 1 and type 2 diabetes.
Methods
Systematic review and meta-analysis. We searched PubMed, Psychinfo, Embase and the Cochrane library for randomized controlled trials evaluating the outcome of depression treatments in diabetes and comorbid MDD or subthreshold symptoms published before August 2019 compared to Care As Usual (CAU), placebo, waiting list (WL), or active comparator treatment as in a comparative effectiveness trial (CET). Primary outcomes were depressive symptom severity and glycaemic control. Cohen’s d are reported.
Results
Forty-three randomised controlled trials (RCTs) were selected and 32 RCTs comprising 3543 patients were included in the meta-analysis. Our meta-analysis showed that, compared to CAU, placebo or WL, all interventions showed a significant effect on combined outcome 0,485 (95%CI 0,360;0,609). All interventions showed a significant effect on depression. Pharmacological treatment, group-therapy, psychotherapy and collaborative care had a significant effect on glycaemic control. High baseline depression score was associated with a greater reduction in HbA1c and depressive outcome. High baseline HbA1c was associated with a greater reduction in HbA1c.
Conclusion
All treatments are effective for comorbid depression in type 1 diabetes and type 2 diabetes. Over the last decade, new interventions with large effect sizes have been introduced, such as group-based therapy, online treatment and exercise. Although all interventions were effective for depression, not all treatments were effective for glycaemic control. Effective interventions in comorbid depressive disorder may not be as effective in comorbid subthreshold depression. Baseline depression and HbA1c scores modify the treatment effect. Based on the findings, we provide guidance for treatment depending on patient profile and desired outcome, and discuss possible avenues for further research.
