Overview
The objective of this project is to develop a behavioral intervention that combines wearable continuous glucose monitoring (CGM) with smartphone feedback and educational video clips generated by artificial intelligence (AI) software to improve glycemic control among individuals with pre-diabetes. The goal is to prevent transition to type 2 diabetes (T2D).
Description
The primary objective of this new project is to enhance glycemic control in individuals with prediabetes and deter the progression to Type 2 Diabetes (T2D) within the Los Angeles (LA) County community. Our proposal involves conducting a Phase 0 intervention development study. This study will enlist a final sample of N=50 adults who speak English and/or Spanish, have non-clinical prediabetes, and test positive for prediabetes via a finger-prick A1c% screening. Participants will wear CGM devices for 20 days, with glucose data masked for the first 10 days and unmasked for the next 10 days. During the unmasked phase, participants will receive daily health education videos on their smartphones. The study will compare the duration of glucose excursions between the masked and unmasked phases to assess the impact of CGM feedback and health education on glucose regulation.
