Effect of psychological intervention on glycemic control in middle-aged and elderly patients with type 2 diabetes mellitus: A systematic review and meta-analysis.

Aim: There is an ongoing debate regarding the influence of psychological interventions on glycemic control in middle-aged and elderly patients diagnosed with type 2 diabetes. To establish evidence-based medical support for the therapeutic application of these interventions, this meta-analysis seeks to assess the impact of psychological interventions on glycemic control in middle-aged and elderly individuals with type 2 diabetes.

Methods: This study systematically searched six electronic databases for randomized controlled studies of psychological interventions applied to middle-aged and elderly patients with type 2 diabetes, and the search time frames were all from the time of database creation to the search period from the establishment to March 2023. Two evaluators independently screened the literature evaluated the included studies' risk of bias, and carried out a meta-analysis using the RevMan5.4 program.

Results: A total of 7 studies with 728 participants complied with the eligibility criteria. Meta-analysis showed that glycated glucagon was reduced in the psychological intervention group compared to the control group (MD = -0.26, 95 %CI:-0.51,-0.01,p = 0.01) with a statistically significant difference (p < 0.05). and their sensitivity analyses all showed stable and credible results.

Conclusions: This review concludes that psychological interventions, when applied to middle-aged and elderly individuals with type 2 diabetes, proved to be more effective in reducing HbA1c levels compared to standard care. Nevertheless, further evidence-based research is essential to elucidate the specific types of psychological interventions that contribute to improved glycemic control outcomes in middle-aged and older adults with type 2 diabetes.
