PURPOSE: To evaluate the inclusion of technology, a wearable device and smartphone, into the popular lifestyle modification program: the Diabetes Prevention Program - Group Lifestyle Balance Program (DPP - GLB). The DPP - GLB Program has shown great success in reduction of progression toward T2DM. However, it was unknown how integrating technology would affect overall program outcomes, which included the attainment of 150 minutes of physical activity (PA)/week and weight loss trending toward 7%. METHODS: Men and women over the age of 40, and at risk for prediabetes, were recruited. The study included an initial four weeks of baseline PA testing, followed by 12 weeks of lifestyle intervention. Individualized weight loss and PA goals were set. Participants self-randomized to the control (N = 11) or the technology group (N = 13). Session participation was high. Technology participants missed 8.3% of sessions, while control participants missed 18.2% of sessions. RESULTS: Participants were aged 66.24 (SD = 7.38) years. At baseline, 21% of participants were overweight, and 79% were obese. Using a generalized estimating equation to estimate average weight lost, participants lost 0.46 lbs/week. One hundred percent of technology participants lost weight, while 73% of control participants lost weight. Only 7.7% of technology participants reached the 7% weight loss goal, while 27.2% of control participants reached the 7% weight loss goal. Both groups lost similar amounts of weight in averages, with technology participants losing an average of 7.35 lbs and control participants losing an average of 7.79 lbs. At study conclusion, 37% of participants were overweight, and 63% were obese. Although statistical significance was not found, we believe clinical significance was found. The majority of participants (63%) self-reported inactivity during the initial meeting. Technology participants averaged PA tracking for 72.5 days while the control group averaged 47.7 days of PA tracking of 77 days available. CONCLUSION: Monitoring PA with technology can reinforce positive lifestyle changes to encourage users and increase activity due to instant feedback from the device. Participants can be successful with weight loss by going through the GLB Program, with or without technology, reinforcing the importance of lifestyle modification.
