Abstract P110: Mean Daily Pedometer Step Count is Associated With Weight Loss

Introduction: Increased physical activity (PA), along with reduced energy intake, are the key strategies to achieve weight loss. However, there are challenges to obtaining accurate PA data. Many studies rely on self-report, which is easily accessible and inexpensive but is known to have numerous limitations. Pedometers are a relatively inexpensive and accessible method to objectively measure certain aspects of PA. However, their limitations include the inability to assess certain types of PA such as swimming and cycling. The purpose of this analysis was to examine the associations between self-reported PA, pedometer step count data and weight loss in a behavioral weight loss intervention. Hypotheses: 1) Self-reported PA will not be associated with weight loss. 2) Higher daily pedometer step count will be associated with greater weight loss. Methods: This was a secondary analysis of 6-month data from the Self Efficacy Lifestyle Focus (SELF) Trial. Self-reported PA was assessed using the Modifiable Activity...
