Continuous Glucose Monitoring for Self-Management of Type 2 Diabetes in Young Adults

The prevalence of type 2 diabetes (T2D) is rising in young adults and is associated with increased complications and reduced life expectancy. Poor adherence to diabetes self-management behaviors is common in young adulthood, often leading to poor glycemic control, and existing self-management interventions have had limited effectiveness in this age group. Continuous glucose monitors (CGMs) provide real-time glucose data that can support behavior change and reduce common self-management barriers such as glycemic unawareness, but their use in younger adults is limited. As "digital natives," young adults are well-poised to benefit from CGM interventions, particularly if they reduce barriers of standard self-management education (e.g., time burden). Qualitative data has shown that young adults are interested in CGM use but lack both access to CGMs and understanding of how to best utilize CGM data. The purpose of this proposal is to utilize a mixed-methods, community-engaged approach to generate pilot data for the development of a self-management intervention that pairs CGM glucose data with behavioral data (e.g., FitBit step count, dietary intake) to improve self-management and glycemic awareness and control. Young adults with T2D will be recruited to participate in a 30-day trial wear of CGMs, during which self-management behaviors will also be assessed. Afterward, qualitative interviews with participants will be conducted to understand barriers and facilitators of CGM use, changes in awareness of glucose patterns, and preferences for a CGM-based intervention.
