Primary

Measure	Time frame
Change in the mean number of steps/day recorded in the system between the baseline period and Week 5~6 of the intervention period	—

Secondary

Measure	Time frame
-Changes in other physical activity parameters (energy consumption by activity and self-reported walking time), self-efficacy, self-regulation for physical activity, self-management behaviors, intake of nutrients, biomedical characteristics (blood pressure at home and at hospital, BMI, visceral fat area, HbA1c, fasting/postprandial blood glucose, triglyceride, HDL cholesterol, calculated LDL cholesterol, and medications), and locomotive functions -Primary assessment: during/after Week 5~6 of intervention, secondary assessment: during/after Week 23~24 of intervention	—
