OBJECTIVES
We isolated physical activity attributable to transit use to examine issues of substitution between types of physical activity and potential confounding of transit-related walking with… (More)
PURPOSE
This study developed and tested an algorithm to classify accelerometer data as walking or nonwalking using either GPS or travel diary data within a large sample of adults under free-living… (More)
Precise measurement of physical activity is important for health research, providing a better understanding of activity location, type, duration, and intensity. This article describes a novel suite… (More)
Immigrant and minority women are less physically active than White women particularly during leisure time. However, prior research demonstrates that reported household physical activity (PA) and… (More)
UNLABELLED
Little is known about where physical activity (PA) occurs, or whether different demographic groups accumulate PA in different locations.
METHOD
Objective data on PA and location from 611… (More)
PURPOSE
We assessed the associations between a change in time spent walking and a change in total physical activity (PA) time within an urban living adult sample to test for additive or substitution… (More)
