The investigators are doing a study to learn how to support patients aged 60+ in taking more breaks from sitting and reducing total sitting time. The goal of the study is to find out if a sitting time reduction intervention reduces sitting time compared with a control group.
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.

Change in Hours of Sitting Time
Average hours of sitting time over the last 7 days measured at baseline and 12 weeks later
Time frame: 12 weeks
Sit-to-stand Transitions
Change in average daily number of activPAL-measured sit-to-stand transitions, from baseline to 12 weeks
Time frame: 12 weeks
Periods of Sitting for 30+ Minutes
Change in average daily number of activPAL-measured periods of sitting for 30+ minutes without standing, from baseline to 12 weeks
Time frame: 12 weeks
Physical Function
Change in Short Physical Performance Battery (SPPB) scale score, from baseline to 12 weeks. The range of scores is 0 to 12, higher values represent better physical function.
Time frame: 12 weeks
Blood Pressure (Systolic Blood Pressure)
Change in average of second and third blood pressure reading (for systolic blood pressure), from baseline to 12 weeks
Time frame: 12 weeks
Fasting Glucose (mg/dL)
Change in fasting glucose (mg/dL) from finger stick blood draw, from baseline to 12 weeks
Time frame: 12 weeks
Total Cholesterol (mg/dL)
Change in total cholesterol (mg/dL) from finger stick blood draw, from baseline to 12 weeks
Time frame: 12 weeks
Depressive Symptoms

Change in Patient Health Questionnaire (PHQ-8) scale score, from baseline to 12 weeks. The scale range is 0 to 24 with higher scores representing higher depressive symptoms. Scores of 10 or more are considered major depression.
Time frame: 12 weeks
