Abstract Introduction:<\b>
Active School Transportation (AST) constitutes an opportunity for children to increase their daily physical activity (PA). However, little is known about how much AST contributes to PA during specific periods within a school day. The aim of this study was to evaluate the association between AST and PA during three sections of children's school day. Methods:<\b>
School children wore an accelerometer ActiGraph wGT3X-BT during 7 consecutive days. Children completed a question about school transportation habits (active and passive travelers), and weight and height were measured. Multilevel linear regressions were performed to assess the association between AST and total moderate-to-vigorous PA (MVPA) during the journey to school, school-hours and out-school time adjusting for gender, age, nutritional status and accelerometer wear time. Results:<\b>
179 children (47.4% male; aged 10.2± 0.9 years; 64.5% overweight/obese) provided valid data. After controlling by covariates, active travelers to school during the journey to school were significantly more physically active than children who travel by car or bus (2.11±0.5 MVPA min/day 95% CI 1.13-3.09; p<0.001). No differences were found in school-hours (2.80±1.9 MVPA min/day 95% CI -1.08-6.68; p=0.158) and out-school periods between active and passive travelers (1.27±2.7 MVPA/day 95% CI -4.12- 6.66; p=0.644).Conclusions: Although evidence show a substantial association between AST and overall daily PA, in this sample of Chilean children, AST was associated only with higher PA levels of the journey to school period. AST has a positive (but statically negligible) effect during daily PA during school-days and out-school time. External funding details Funding: FONDECYT 11160720 – UNETE 14-0008
