| Purpose: |
|
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).
|
| Study summary: |
|
Long-term promotion of physical activity is necessary to achieve obesity prevention. This
represents a particular challenge for our intervention design, as few studies have
demonstrated positive long-term physical activity promotion outcomes among Black women. We
have demonstrated the utility of pedometers among low income, ethnically diverse
populations. The efficacy of pedometer utilization for the prevention of weight gain,
however, hinges on long-term utilization of the devices. We hypothesize that recommendation
for the step count attainment may affect individual's long-term utilization of pedometers,
as well as physical activity levels and BMI.
This study is a 24-week experimental trial to examine whether intervention recommendations
promote long-term adherence to a pedometer-based physical activity regimen. A two-group,
block design will be used in the proposed study. Eligible women will be randomly assigned to
one of two experimental conditions (n=113 per condition): 1) receiving a 10,000 steps/day
recommendation or 2) receiving an adaptive recommendation. The adaptive recommendation will
update the participant's recommended step count attainment in 2500 steps/d increments, until
she reaches the 10,000 steps/d threshold. For example, if during Week One, a participant
reports a mean of 5000 step/d, her adaptive recommendation will be 7500 steps/d. Once she
reaches the 7500 steps/d level, she will receive a new recommendation of 10,000 steps/d.
Participants will be provided pedometers and will be asked to report their step counts
weekly, using an interactive voice response system. Brief non-intervention feedback will be
provided during these calls. Assessments (including self-report survey and anthropometric
measurements) will be conducted at baseline and 24-weeks post baseline. |
