Increasing exercise adherence in people with type 2 diabetes and prediabetes using self-monitoring strategies : a feasibility study.

University of British Columbia

Exercise levels in people with prediabetes and type 2 diabetes (T2D) are poor. Exercise can help this population manage their condition by improving blood glucose (BG) regulation for up to 24hr post-exercise. Self-monitoring is a crucial skill for facilitating health behaviour change, and may be particularly relevant for people with prediabetes and T2D as self-monitoring BG can improve many clinically relevant health markers. The impact of self-monitoring BG to improve exercise adherence is not well established. The purpose of this pilot study was to test the efficacy of a self-monitoring group-based intervention using continuous glucose monitors (CGM) at increasing exercise behaviour in individuals with impaired BG. Thirteen participants with prediabetes or T2D were randomized to an 8-week standard care exercise program (CON; n = 7) or 8-week self-monitoring exercise program (SM; n = 6). Participants in SM were taught how to self-monitor their exercise and BG, goal set, and observe how exercise influences BG using CGM. It was hypothesized that monitoring and being privy to real-time personal BG feedback would facilitate self-monitoring, resulting in greater exercise adherence. RM ANOVA revealed significant Group x Time interactions for self-monitoring (p < .01), goal-setting (p = .01), and self-efficacy to self-monitor (p = .01), such that participants in the SM condition increased significantly more across the 8-week program and at 1-month follow-up compared to the CON condition. Exercise behaviour was not significantly different between conditions, but medium effect sizes suggest the SM condition had greater increases compared to CON. The SM condition also had significantly higher attendance rates to the exercise program (p = .03), and a significantly greater proportion of participants re-registered for an exercise program (p = .048) compared to CON. Following the exercise program, participants in both conditions experienced improvements in mental health related quality of life, waist circumference and fitness (p’s < .05). Findings suggest self-monitoring is a valuable skill for increasing exercise adherence in people with impaired BG control, and provide initial support for the use of CGM to foster self-monitoring.
