Brief Summary

This study aims to promote daily physical activity in cancer survivors who are at high risk for type 2 diabetes (T2D) by using a personalized biological-based feedback strategy. T2D is one of the most common co-occurring conditions in cancer survivors and can worsen cancer-related health outcomes, especially in those who are insufficiently active. The investigators hypothesize that seeing the immediate impacts of exercise on their biological status will motivate cancer survivors to exercise. The investigators will use real-time data from continuous glucose monitor to demonstrate the acute impact of physical activity and measure daily activity levels using wearable trackers. As wearable sensor technology is constantly advancing, this study is the first step to exploring how researchers can use wearable sensors to help people make a direct connection between their daily behaviors and health outcomes.

Outcome Measures

Primary Outcomes (1)

  • Feasibility of delivering personalized glucose-based feedback

    The intervention will be considered feasible if ≥ 80% of participants in the intervention group are adherent to the self-monitoring protocol and ≥ 80% of participants complete the post-intervention assessment.

    Through study completion, an average of 3 months.

Secondary Outcomes (1)

  • Changes in daily physical activity level

    Through study completion, an average of 3 months.

Study Arms (2)

Biofeedback Group

EXPERIMENTAL
Behavioral: Glucose-based biofeedback

Standard Care Group

ACTIVE COMPARATOR
Behavioral: Standard feedback

Interventions

Participants will wear a Fitbit activity tracker and receive personalized text messages over a 12-week period. During the first 4 weeks of the study period, participants will also wear a continuous glucose monitor to check their glucose levels in real-time and receive text messages based on their activity and glucose data.

Biofeedback Group

Participants will wear a Fitbit activity tracker and receive non-personalized text messages over a 12-week period.

Standard Care Group
