  • Published on 02/2007

Objective To examine how travel by walking before and after school contributes to total physical activity of adolescent girls.

Design Cross-sectional sample.

Setting 36 middle schools from Arizona, Maryland, Minnesota, New Orleans, San Diego and South Carolina participating in the Trial of Activity for Adolescent Girls (TAAG). Participants—1721 6th grade girls consented to participate; adequate information was available for 1596 (93%) of participants.

Main outcome measure Travel by walking before school, after school, and before and after school combined, assessed from the 3-Day Physical Activity Recall (3DPAR). Mean minutes of physical activity, measured by accelerometry, were estimated for total physical activity (light, moderate, vigorous), moderate to vigorous activity (MVPA), and MVPA (3 MET).
