• 1 other identifier: IRB-24-8450
• Study Type: interventional
• Target: 40
• Locations: 1 country
• Sites: 1

Brief Summary

Type 2 diabetes in increasing common in young adults. Utilizing a mixed-methods, community-based approach, this study offers continuous glucose monitors (CGMs) to young adults with type 2 diabetes for 30 days, and collects both quantitative and qualitative data to understand barriers and facilitators of CGM use, participants' changes in awareness of glucose patterns while using the CGM, and preferences for a CGM-based self-management intervention.

Conditions

Type 2 Diabetes Mellitus (T2DM)

Keywords

continuous glucose monitor; type 2 diabetes; young adult

Outcome Measures

Primary Outcomes (1)

• Qualitative data regarding CGM use

  Semi-structured qualitative interviews will be conducted to understand barriers and facilitators of CGM use, changes in awareness of glucose patterns or relationships between glucose and health behaviors, and preferences for a future CGM-based intervention.

  Immediately after the intervention

Secondary Outcomes (1)

• Acceptability and feasibility of CGM wear

  Immediately after the intervention

Other Outcomes (6)

• Glucose time-in-range

  30 days (during the intervention period)

• Diabetes self-care behaviors

  One week (7 days), last week of the intervention

• Diabetes distress

  Baseline and follow-up (immediately after the intervention)

Study Arms (1)

CGM Wear

EXPERIMENTAL

Participants will wear a continuous glucose monitor for 30 days. They will also wear a FitBit activity tracker watch and complete weekly surveys to report diabetes self-management behaviors.

Device: Continuous glucose monitor

Interventions

Continuous glucose monitor DEVICE

Participants will wear a continuous glucose monitoring sensor for 30 days. They will also wear a FitBit wrist watch to be able to track their physical activity and they will complete weekly surveys to report diabetes self-management behaviors. After the 30 days, they will participate in a qualitative interview to respond to questions about their experiences.

CGM Wear

Model Details: The intervention consists of a 30-day CGM wear and weekly surveys. Participants will be asked to maintain continuous use of CGM for 30 days and share their CGM data over that period. CGM sensors will be provided free-of-charge. Additionally, participants will be asked to complete weekly electronic surveys measuring self-management behaviors.
