Changes in active travel of school children from 2004 to 2010 in New South Wales, Australia.
OBJECTIVE
To describe changes in mode of commuting to school among Australia students between 2004 and 2010 and in relation to body mass index (BMI) and cardio respiratory fitness.


METHODS
Representative cross-sectional survey of school children in grades 6, 8 and 10 in 2004 (n=2750) and 2010 (n=4273). Information on how many days students use active and passive travel modes to and from school and measured BMI and cardio-respiratory fitness test were collected as part of the New South Wales (NSW) Schools Physical Activity and Nutrition Surveys (SPANS).


RESULTS
Active travel to school remained stable between 2004 and 2010, although there was a small increase in minutes spent on active travel. There was no association between active travel and body mass index. In 2010 there was a significant association between frequent car use and low cardio-respiratory fitness (adjusted OR=1.7, CI 1.3-2.1).


CONCLUSIONS
It is a positive finding that the generational decline in active travel may have levelled out. Student inactivity associated with regular car use is plausibly related to lower cardio-respiratory fitness, but active commuting may not be of sufficient energy expenditure to impact upon BMI.
