Financial incentives and health coaching to improve glycemic outcomes among young adults with type 1 diabetes: A factorial randomized trial (SweetGoals)
Authors' conclusion
Incentives and coaching both improved critical mealtime behavior but through different strategies.
Study context
- Population
- Young adults with T1D recruited nationally; all received a smartphone app that accessed device data and provided weekly goal feedback
- Participants
- 300 adults
- Comparison
- Financial incentives and web health coaching for glycemic control
- Primary endpoint
- HbA1c
- Follow-up
- 12 months
Methodological detailsfactorial, Intervention lasted 6 months; HbA1c assessed at baseline, +6 months and +12 months
- Factorial
- Intervention lasted 6 months; HbA1c assessed at baseline, +6 months and +12 months
Primary result
As reported in the abstract
baseline to +12 months
- HbA1c significantly reduced from baseline to +12 months across all participants
- Indirect effects of both incentives and coaching on HbA1c reductions were significant, partially mediated by mealtime but not glucose checking goal achievement
- No synergistic (interaction) effect of incentives and coaching
