Feasibility and outcomes from using a commitment device and text message reminders to increase adherence to time-restricted eating: A randomized trial
Authors' conclusion
A bidirectional texting strategy was feasible for helping patients with obesity and hypertension initiate and adhere to time-restricted eating. Adding a commitment device to bidirectional texting did not increase adherence to time-restricted eating compared with attention control, nor were there significant between group changes in blood pressure or weight, but these comparisons were underpowered.
Study context
- Population
- Patients with obesity and hypertension seen in cardiology clinics
- Participants
- 37 patients
- Comparison
- Commitment device vs Attention control
- Commitment devicen = 17
- Attention controln = 20reference
- Primary endpoint
- Days per week adherent to time-restricted eating (daily self-report)
- Follow-up
- 18-week study period
Methodological details12-week intervention, then 6-week follow-up
- 12-week intervention, then 6-week follow-up
Primary result
As reported in the abstract
Days/week adherent to time-restricted eating (daily self-report)
- Commitment device vs Attention control: P = 0.23
- Control arm = Attention control; intervention arm = Commitment device
Further findings
SBP
- Mean SBP declined from 135 to 128 mm Hg among all participants
- P = 0.006
- No difference between groups in change from baseline BP
- P = 0.74
Weight
- Weight decreased from 229 to 223 pounds among all participants
- P = 0.25
- No significant difference between groups in change from baseline weight
- P = 0.84
