Measure
Intervention Group (Jawbone Up Wrist Monitor)
Subjects will have clinic visits, home visits, and telephone visits. Subjects will be asked to wear a wrist monitor (Jawbone Up) for duration of the study, will meet with the study team to review Physical Activity Education and also be asked to wear the ActivPAL device to assess sitting time. Jawbone Up: Jawbone Up is a wrist wore water resistant activity monitor. Physical Activity Education: A study team member will discuss benefits of changing sitting habits and ways to make changes to personal habits. ActivPAL: Devices measures postural changes over time. Participants will wear device for 7 days. The device measures time sitting, standing, and posture changes (i.e. sit-to-stand).
Control Group (No Wrist Monitor)

Standard Deviation .764

SECONDARY outcome

Timeframe: Change from Baseline to Week 12

Population: Only three participants had data available for the mixed meal tolerance test

The average area under the curve at week 12 minus the average area under the curve at baseline. Blood was collected at baseline (pre-mixed meal). Post-mixed meal it was collected at 15, 30, 45, 60, 90, 120 minutes. The Area Under the Curve (AUC) was computed using the trapezoidal rule as we have previously described (Burns et. al. 2012, Morris et al 2014). This results in a single AUC pre-intervention value, and a single AUC post-intervention value for each metabolic outcome measure (glucose, insulin, etc). The Area Under the Curve (AUC) for each individual is calculated as a single unitless value that results from calculating the definite integral under a timecourse curve. This method has been widely used and cited in metabolic studies for more than two decades https://doi.org/10.2337/diacare.17.2.152. This results in a single unitless AUC pre-intervention value, and a single AUC post-intervention value for each metabolic outcome response measure (glucose, insulin, etc).

POST_HOC outcome

Timeframe: Change from baseline to week 12

Population: Only three participants had data available for the mixed meal tolerance test

HOMA-IR (Homeostatic Model Assessment of Insulin Resistance) is calculated as fasting insulin (microU/L) x fasting glucose (nmol/L)/22.5. The average HOMA-IR at week 12 minus the average HOMA-IR at baseline. A lower score means a person is more sensitive to insulin, whereas a higher score indicates greater resistance to insulin. The HOMA-IR is a tool for calculating degree of insulin resistance. Given that this is a product of insulin and glucose values divided by a constant, there is no maximum score for this measure. The minimum score would be zero as neither insulin or glucose would drop below zero.
