Abstract

AIMS:

Despite the known benefits, 60% of individuals with diabetes do not engage in regular physical activity (PA). This pilot study tested the effects of a counseling intervention using continuous glucose monitoring system (CGMS) feedback on PA self-efficacy, PA levels, and physiological variables.

METHODS:

Adults (N=52) with type 2 diabetes (non-insulin requiring, inactive) were randomized to intervention (n=27) or control (n=25) groups. Both groups received 90min of diabetes education with a follow-up phone call 4 weeks later. The intervention group also received counseling derived from self-efficacy theory. This intervention included feedback on each participant's CGMS graph and used role model CGMS graphs to clearly depict glucose reductions in response to PA. Outcomes were assessed at baseline and 8 weeks.

RESULTS:

Participants receiving the intervention had higher self-efficacy scores than the control group for sticking to activity/resisting relapse at 8 weeks (p<0.05), indicating more confidence in maintaining a PA program. Intervention group participants light/sedentary activity minutes decreased significantly (p<0.05), moderate activity minutes increased significantly (p<0.05), and, HbA1c and BMI decreased significantly (p<0.05).

CONCLUSIONS:

These data suggest that PA counseling interventions using CGMS feedback for individuals with type 2 diabetes may improve PA levels and reduce risk factors for diabetes-related complications.
