The investigators propose to develop and conduct a pilot study to test a wearable technology-based sedentary behavior reduction intervention in type 2 diabetes patients. The participants in the first cohort (n=15), 'Sit Less Version 1' will be randomized to either the control group or the sedentary behavior reduction intervention group. The intervention group will target a 120 minute per day reduction in sedentary behavior using an objective activity monitor and mHealth. The study will have an iterative design process with multiple cohorts. After the first cohort completed the study, we will collect their feedback to modify the Sit Less program. With Sit Less Version 2, Cohort 2 (n=20) participants will participate in the intervention as a single group, without randomization. The Sit Less Version 2 will be 8 weeks long.
Specifically, the study aims to: determine the feasibility and acceptability of the sedentary behavior reduction intervention in type 2 diabetes patients by evaluating reach, retention, satisfaction, and compliance with the intervention; evaluate the preliminary efficacy of the sedentary behavior reduction intervention on changes in sedentary time; and explore preliminary effects of the sedentary reduction intervention on physical activity, cardiometabolic markers and patient-centered outcomes.
