Continuous Glucose Monitors Not Accurate in People Without Diabetes
Research indicates that continuous glucose monitors (CGMs) do not accurately reflect blood sugar control in individuals without diabetes.
A study published in Diabetes Technology & Therapeutics analyzed data from the Artificial Intelligence Ready and Exploratory Atlas for Diabetes Insights cohort, which included 421 individuals with type 2 diabetes, 319 with prediabetes, and 232 with normoglycemia.
The researchers, led by Rodriguez, M.D., from Brigham and Women’s Hospital in Boston, found that associations between hemoglobin A1c (HbA1c) and CGM metrics were strongest in individuals with type 2 diabetes, with mean glucose showing the strongest relationships (standardized β = 0.79).
CGMs do not accurately reflect blood sugar control in people without diabetes.
The study highlights the limitations of CGMs in individuals without diabetes, suggesting that alternative methods may be necessary to accurately assess blood sugar control in this population.
Author summary: CGMs are not accurate indicators of blood sugar control in non-diabetic individuals.
