Comparing GPS, Log, Survey, and Accelerometry to Measure Physical Activity.

Objectives: We explored how objectively measured global positioning system (GPS) and accelerometer data match with travel logs and questionnaires in predicting trip duration and physical activity (PA).

Methods: 99 participants wore GPS devices and accelerometers, and recorded all trips in a log for 5 consecutive days. Participants also completed a self-administered questionnaire on PA and travel behaviors.

Changes in physical activity and travel behaviors in residents of a mixed-use development.

Background: Mixed-use developments may be especially promising settings for encouraging walking and other types of physical activity.

Purpose: This study examined the physical activity and travel behaviors of individuals before and after they relocated to Atlantic Station, a mixed-use redevelopment community in metropolitan Atlanta.

Methods: A survey study was conducted to compare the behaviors, experiences, and attitudes of Atlantic Station residents before and after moving to a mixed-use neighborhood.

A model curriculum for a course on the built environment and public health: training for an interdisciplinary workforce.

Despite growing evidence of the direct and indirect effects of the built environment on public health, planners, who shape the built environment, and public health professionals, who protect the public's health, rarely interact. Most public health professionals have little experience with urban planners, zoning boards, city councils, and others who make decisions about the built environment. Likewise, few planners understand the health implications of design, land use, or transportation decisions.
