A Text Messaging Intervention With Financial Incentive for Adolescents With Type 1 Diabetes

Effectiveness of Non-pharmacological Interventions for Adolescents With Type 1 Diabetes in the Last Five Years: A Systematic Review and Meta-analysis

PURPOSE

Evidence on non-pharmacological interventions for adolescents with type 1 diabetes is unclear. This review aimed to evaluate the effectiveness of non-pharmacological intervention in adolescents with type 1 diabetes.

METHODS

We conducted a search on databases from November 11 to 19, 2022, for randomized controlled trials for the effects of non-pharmacological intervention in adolescents with type 1 diabetes. To identify recent research trends, we included studies published from 2017 to November 2022. The risk of bias was assessed using the Cochrane risk-of-bias tool 2.0. To estimate the effect size, a meta-analysis was performed using RevMan 5.4 program and R Studio.

RESULTS

A total of 45 studies were included in the systematic review. Among those, 30 studies were included in the meta-analysis. Non-pharmacological interventions were significantly effective in improving Glycated hemoglobin (HbA1c) (standardized mean difference [SMD] = -0.26, 95% confidence interval [CI]: -0.42, -0.09), quality of life (SMD = 0.44, 95% CI: 0.13 to 0.76), and anxiety (SMD = -0.91, 95% CI: -1.26, -0.56). Subgroup analysis showed that duration of intervention was not a covariate related to HbA1c levels.

CONCLUSIONS

Non-pharmacological interventions have shown effectiveness in improving the HbA1c, quality of life, and anxiety in adolescents with type 1 diabetes. Future studies with more rigorous methodology are needed to confirm and strengthen the validity of these findings. Additionally, attention to changes in the lipid profile and self-care motivation among adolescents with type 1 diabetes is warranted.

Applying Behavioral Economics Theories to Interventions for Persons with Diabetes

PURPOSE OF REVIEW

To introduce behavioral economics (BE), provide a description of how recent prevention and treatment interventions in persons with diabetes have incorporated BE in their intervention strategies, and discuss how BE could be used to inform new treatments for the clinical setting or research.

RECENT FINDINGS

In most of the trials described, researchers incorporated BE into their design in the form of incentives, which can align with present bias, optimism bias, and loss aversion. With only two exceptions, these trials reported preliminary support for using incentives to promote lifestyle modifications and diabetes-related tasks. Additionally, two trials reported promising results for behavior change strategies informed by default bias, while three trials reported promising results for behavior change strategies informed by social norms. Recent trials incorporating BE in prevention and treatment interventions for persons with diabetes generally report promising results, though gaps exist for research and clinical deployment.
