Brief summary
This feasibility study specifically addresses the issue of adapting US dietary guidelines physical activity recommendations to the population of the Lower Mississippi Delta. The hypothesis is that including a pedometer as a self-monitoring tool as part of adapted physical activity guidelines will result in greater immediate increases in physical activity (as monitored by an accelerometer) than an education program alone.
Detailed description
The purpose of this study was to determine if a short-term pedometer-based intervention results in immediate increases in time spent in moderate-to-vigorous physical activity (MVPA) compared to a minimal educational intervention.A sample of 43 overweight adults 35 to 64 years of age participated in a one week pedometer-based feasibility trial monitored by accelerometry. Participants were randomized into a one-week education-only group or a group that also wore a pedometer. Accelerometer-measured MVPA was measured over 7 days at baseline and post-intervention.
Interventions
BEHAVIORALPhysical Activity Educational Materials
A brochure was provided to participants about the health benefits of physical activity and physical activity recommendations
BEHAVIORALPedometer
A pedometer was provided to participants in addition to educational materials about the health benefits of physical activity.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Minutes spent in moderate-to-vigorous physical activity (MVPA) | The primary outcome is measured at baseline and after a 7-day intervention period (1 week) | A GT3X accelerometer is used to monitor each participants physical activity levels for seven consecutive days at baseline and again following a 7-day intervention period. The amount of time per day spent above a threshold of 2200 accelerometer counts/min is averaged over at least three days as the measure of MVPA. |
