Feasibility and acceptability of continuous glucose monitoring and accelerometer technology in exercising individuals with type 2 diabetes.
OBJECTIVE
The aim of this study was to develop role model data for an intervention to motivate non-exercising individuals with type 2 diabetes mellitus to engage in regular physical activity. Toward that end, the study 1) described Continuous Glucose Monitoring System data and obtained role model CGMS graphs, 2) described a monitor to measure exercise amount and intensity and 3) explored participants' experiences of the monitors and perceptions of the glucose monitoring data.


BACKGROUND
Physical activity is a cornerstone of diabetes treatment yet the majority of individuals with diabetes are inactive. Thus, increasing physical activity in these individuals demands innovative interventions.


METHODS
A two-phase, multi-method design was used.


METHODS
In phase 1, a descriptive design was used to describe physical activity patterns and glucose levels for 72 hours in nine exercising adults with type 2 diabetes. In phase 2, a focus group interview was used to collect data from seven phase-1 participants. Verbatim transcripts of the audio taped focus group were analysed for themes and trends.


RESULTS
The glucose monitor data captured lower glucose levels after exercise. Compared to formal diabetes education, visual data from the glucose monitoring technology were perceived as more relevant to participants' particular, everyday experiences with exercise, diet and stress. Participants reported a reinforced commitment to their exercise and diet regimens after using Continuous Glucose Monitoring System. Technology issues were identified, e.g. discomfort wearing activity monitors and forgetting to enter calibration and event data in glucose monitors.


CONCLUSIONS
Participants found that visual glucose monitoring data reinforced self-management behaviors, such as exercise. Our results suggest that data depicting the response of glucose levels to diet and exercise could be a useful tool to change behavior in individuals with type 2 diabetes.
