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

Abstract

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.

Continuous glucose monitoring counseling improves physical activity behaviors of individuals with type 2 diabetes: A randomized clinical trial

“…walking, jogging, running), but less accurate for activities such as weight-lifting, swimming and cycling [25]. Since walking is the preferred type of physical activity in adults with type 2 diabetes [12] and previous research has supported the use of activity monitors to measure physical activity in individuals with diabetes [7,[26][27][28], we chose to objectively measure physical activity with ActiGraph uniaxial accelerometers (Manufacturing Technologies Incorporated, Fort Walton Beach, FL). The monitor was secured by a strap at the participant's right waist and programmed to collect activity counts at 1-min intervals over 7 days.…”

“…37,38 None of the selected studies on pedometerbased interventions assessed issues of feasibility or usability. One trial using an accelerometer-based exercise intervention was reviewed 39 but did not fit the inclusion criteria.…”

New and Emerging Weight Management Strategies for Busy Ambulatory Settings

“…Thirteen studies were identified, and of these, 4 met our inclusion criteria (Table 3). Studies were excluded because they did not report weight loss outcomes (nϭ3), [82][83][84] did not use a randomized controlled design (nϭ4), [85][86][87][88] or the phones used were standard landline phones (nϭ2). 49,89 All 4 studies enrolled primarily white women and were conducted in the community.…”
