Accelerometer Feedback to Promote Physical Activity in Adults with Type 2 Diabetes: A Pilot Study

This study examined whether giving activity feedback to obese, sedentary adults with Type 2 diabetes would improve their adherence to a home-based walking program. 49 subjects were recruited. Ten failed a treadmill cardiovascular test. Another 9 dropped out before the intervention, and 4 dropped out during the intervention. The remaining 26 adults (14 women, 12 men; age M = 48.1 yr., SD = 7.1) received behavioral counseling monthly for 3 mo. regarding exercise. All subjects wore a triaxial accelerometer during these 3 months. Randomly, half of the subjects were blind to the data from the accelerometers, i.e., no feedback, and had counseling based on their self-report diaries. The other half had access to the accelerometer data, got a computerized graph of their physical activity for the period between counseling sessions, and had counseling based on these objective data, i.e., feedback. The feedback group showed an increase in exercise over the 3 mo. The nonfeedback group showed an increase in activity at 1.5 mo. but reverted to their baseline exercise levels at 3 mo. However, analysis of variance showed there was at least an 8% probability that this effect was due to chance, so the hypothesis that feedback would improve exercise adherence could not be supported. Further studies with larger sample sizes and greater control of experimental conditions are needed to determine the utility of objective activity feedback.
