Impact of Continuous Glucose Monitoring and Education Intervention on Glycemic Control and Behavioral Changes in Pre-Diabetic Adolescents (PreDiA-CGM)

28. april 2026 opdateret af: University of Arizona

A Pilot Study Evaluating the Impact of Continuous Glucose Monitoring and Education Intervention on Glycemic Control and Behavioral Changes in Pre-Diabetic Adolescents

Prediabetes is a condition wherein blood sugar levels are elevated but not sufficiently high enough to diagnose type 2 diabetes mellitus (T2D). Prediabetes is a critical risk factor for the development of T2D in pediatric populations. This progression can occur over a short period of time, limiting the efficacy and impact of existing interventions and recommendations targeting this population. There is growing evidence on the use of continuous glucose monitors (CGMs) in adult prediabetic populations to prevent the development of T2D, though this intervention has not been thoroughly investigated in pediatric populations.

The investigators are proposing a pilot study of 25 prediabetic adolescents enrolled in a 20-week study. For the initial 10 weeks of the study, the participants will go without CGMs and undergo clinically recommended education on their condition as standard of care. In the 10 weeks following, participants will be given a CGM to wear and instructions on its use. Surveys will be issued to all participants over the entirety of the study to follow behaviors surrounding food and physical activity.

pre-diabetic patients aged 13-18
The purpose of this pilot study is to evaluate the effectiveness of CGMs in assisting prediabetic adolescents to make appropriate lifestyle changes aimed at preventing the development of T2D. The investigators hypothesize that the use of CGMs over 10 weeks will result in beneficial lifestyle changes, relative to a period without CGM. The investigators will evaluate beneficial lifestyle changes by following eating habits, physical activity levels, and biometric measurements

Tidsramme
Behavioral Changes as measured by questionnaires
Tidsramme: 20 weeks
Participants will complete a standardized questionnaire assessing dietary intake and physical activity every two weeks throughout the study period. Responses will be recorded using Likert-scale measures. Questionnaire results will be compared across study phases, including before and after continuous glucose monitor (CGM) use, to evaluate changes over time.
