This study used objective measurement to compare the difference of physical activity levels between children who walked and those that were driven to school, and to investigate the proportion of children meeting physical activity guidelines by mode of travel to school. Fifth- to- sixth grade students in three public primary schools in Taipei municipal area were invited to take part in the study. Students wore an accelerometer for seven days and completed a brief questionnaire to report their mode of transportation to school. Of the 115 children who volunteered to participate in the study, 102 of them fulfilled the inclusion criteria. The total volume of physical activity and the time spent in moderate-to-vigorous physical activity (MVPA), as recorded by the accelerometer, was estimated for weekdays and weekends, and groups of children were compared by mode of transportation to school. Data were analyzed using Chi-square test and t test. The main results of the present study were as follows: (1) Children who walked to school (N=66) were significantly more active than those who traveled by car (N=36) (441.0±130.8 vs. 385.2±102.5 accelerometer counts per minute, p=0.04), and accumulated more minutes of MVPA (99.7±34.7mins vs. 86.5±30.5mins, p=0.05) during weekday. MVPA for children who walked -100-to school was approximately 33% greater before school, compared with those who traveled by car (11.4±5.1mins vs. 7.6±3.6 mins, p=0.01). (2) Students who walked to school appeared to be more active on the weekends than those who traveled by car (376.9±171.3 cpm vs. 284.6±85.4 cpm, p＜0.01), and accumulated 25 additional minutes of MVPA per day (p＜0.01). (3) No significant difference was found between travel groups in the proportion of children meeting physical activity guidelines.
