Effectiveness of self-management interventions on Type 2 diabetes among young adults (18-45 years): A systematic review and meta-analysis.

AIMS

Self-management interventions effectively improve health outcomes in adults with Type 2 diabetes. Young adults living with Type 2 diabetes are at a higher risk of diabetes-related complications, hospitalisation and reduced quality of life. While self-management is key in diabetes care, its effectiveness in young adults with Type 2 diabetes remains unclear. This review assessed self-management interventions' impact on health outcomes in young adults (18-45 years) with Type 2 diabetes.

METHODS

Five electronic databases were searched from inception to May 2024. Trials evaluating self-management interventions versus usual care in young adults were included. Outcomes of interest were clinical, self-care behaviour and psychological health. Meta-analysis used a random effects model; study quality was assessed using the Cochrane risk of bias tool (RoB2) and the JBI checklist for quasi-experimental studies. The review followed PRISMA guidelines and was registered on PROSPERO (CRD42024522979).

RESULTS

Ten studies were included, nine in the meta-analysis, which reported no significant differences between the intervention and control groups in HbA1c, body mass index, weight, waist circumference, blood pressure, lipids, depression or self-efficacy outcomes. Nevertheless, these findings are imprecise due to few studies, missing data and small sample sizes. Commonly used behaviour change techniques were goals and planning, shaping knowledge and feedback/monitoring.

CONCLUSIONS

Existing self-management interventions did not improve clinical and psychological outcomes among young adults (18-45 years) living with Type 2 diabetes. More effective strategies are needed for this priority population.
