I-STAND R21: Reducing Sedentary Time in Older Adults

More than one-third of American adults over 60 have a body mass index \> 30 kg/m2. These older adults have more sedentary time than any other group -- an average of 10-11 hours per day. Reducing the sedentary behavior of older adults with obesity, rather than only promoting more intensive physical activity, could provide a more feasible approach to health promotion. This randomized control pilot trial will evaluate a 12-week intervention to decrease sitting time and increase standing time and light physical activity among sedentary older adults a body mass index \> 30 kg/m2 as compared to control group. Baseline and 12-week measurements include anthropometric measures, blood draw by finger stick, cardiovascular health assessments, physical function tasks, and a survey. The intervention will consist of two in-person visits with a health coach followed by phone-based coaching.
