The effect of continuous glucose monitoring feedback on glycaemic variability in youth with obesity: A within‐participant feasibility study
Authors' conclusion
This trial supports the feasibility and acceptability of CGM use in youth with obesity. Given the exploratory nature of this study, longer-term research is needed to evaluate its effectiveness in modifying health behaviours and metabolic outcomes in this population.
