An observational study on glycemic trajectories during ascent, stay, and descent in a 45-day high-altitude exposure
Authors' conclusion
Short-term high-altitude exposure induces mild, reversible disturbances in glucose regulation, with significant inter-individual heterogeneity.
Study context
- Population
- Healthy adults on a 45-day high-altitude expedition (ascent 2,800 to 4,531 m, stay, descent) with continuous glucose monitoring (CGM)
- Participants
- 8 adults
- Exposure
- Cluster 1 vs Cluster 2
- Outcome
- Glycemic dynamics across altitude-defined phases
Methodological detailsunsupervised clustering
- Unsupervised clustering
Main finding
As reported in the abstract
Peak glycemic variability (CV) at extreme altitude
17.3%
TIR
>97%
Observational data: associations, not effects.
