NCT00939081

Brief Summary

The purpose of this study is to examine whether pedometer step count recommendations (10,000 steps/day versus an adaptive recommendation) are differentially associated with the primary outcome of adherence to the pedometer-based physical activity regimen and the secondary outcomes of change in physical activity and body mass index (BMI).

Outcome Measures

Primary Outcomes (1)

  • Adherence to the pedometer-based physical activity regimen

    24 weeks post baseline

Secondary Outcomes (2)

  • Change in physical activity

    24 weeks post baseline

  • Change in BMI

    24 weeks post baseline

Study Arms (2)

10,000 step/day recommendation

ACTIVE COMPARATOR

Participants will receive a standard 10,000 step/day recommendation and 3 education sessions: at baseline, at 3 months and at 6 months.

Behavioral: 10,000 step/day recommendation

Adaptive recommendation

EXPERIMENTAL

The adaptive recommendation will update the participant's recommended step count attainment from 7,000 to 8,000, then 10,000 steps/day. The SMS-based self-monitoring system will collect three data points each day from participants in this group: 1) total number of steps/d recorded by the pedometer during the previous day (steps/d); 2) performance on 2nd weight loss goal; and 3) performance on 3rd weight loss goal.

Behavioral: Adaptive step recommendation

Interventions

Participants in this group receive 3 education sessions: at baseline, at 3 months and at 6 months. The adaptive recommendation will update the participant's recommended step count attainment from 7,000 to 8,000, then 10,000 steps/day.
