Objective Determination of Eating Occasion Timing: Combining Self-Report, Wrist Motion, and Continuous Glucose Monitoring to Detect Eating Occasions in Adults With Prediabetes and Obesity
Authors' conclusion
The continuous glucose monitor and WM detected overlapping but not identical meals and may provide complementary information to self-reported EO.
Study context
- Population
- Adults with prediabetes or moderately controlled T2D and obesity; 59 ± 11 years, 62% female, 51% White, body mass index (BMI) 34.2 ± 4.7 kg/m²; monitored for 10 days
- Participants
- 39 adults
- Exposure
- Eating occasion timing by wrist motion and continuous glucose monitor (CGM) vs self-report
- Outcome
- Time-of-day of first eating occasion
Main finding
As reported in the abstract
SR
08:24
median · IQR 07:00-09:59
Wrist motion (WM)
9:42
median · IQR 07:46-12:26
CGM
06:55
median · IQR 04:23-10:03
Observational data: associations, not effects.
Further findings
| Outcome | SR | WM | CGM |
|---|---|---|---|
| Time-of-day of last eating occasion | median 20:20 (IQR 16:50-21:42) | median 20:12 (IQR 18:30-21:41) | median 21:43 (IQR 20:35-22:16) |
Overlap of eating occasions (EOs) detected vs SR (tolerance ±30, 60 and 120 minutes)
- Overlap SR and CGM
- 55% to 80%
- Overlap SR and WM
- 52% to 65%
