Approximately 42% of employment in Texas cities is performed in sedentary office settings. Currently there is insufficient data on the amount of physical activity that workers engage in during a workday. Additional data is needed on the impact of increasing walking during the work week. This study will identify current walking trends for office workers in both urban and suburban settings in Texas and determine the ability of simple interventions to begin increasing walking for some daily or weekly trips. The impact of electronic information about short walking trips and physical activity on increasing walking will be tested. The investigator will also explore collecting travel information electronically as a means to improve recall and accuracy of data on walking trips.
