To investigate differences in moderate-to-vigorous physical activity (MVPA) from school-travel between adolescents in urban and suburban neighbourhoods and to describe its relative contribution to MVPA on school days. Methods. We measured 243 adolescents (51% male, grades 8–10) from Vancouver's walkable downtown core and its largely car-dependent suburb Surrey (fall 2011, 2013). We estimated mean school-travel MVPA from accelerometry (hour before/after school on ≥ 2 days; n = 110, 39% male) and compared school-travel MVPA by neighbourhood type and school-travel mode. The influence of mean school-travel MVPA on mean school-day MVPA (≥600 min valid wear time on ≥2 days) was examined by linear regression. Results. Over half of students used active modes (urban: 63%, suburban: 53%). Those using active travel and living in the urban neighbourhood obtained the most school-travel MVPA (22.3 ± 8.0 min). Urban passive travellers used public transit and obtained more school-travel MVPA than suburban students (16.9 ± 6.2 vs.8.0 ± 5.3, p b 0.001), who were primarily driven. Regardless of mode or neighbourhood type, over one-third of school-day MVPA was explained by school-travel MVPA (R2 = 0.38, p b 0.001). Conclusion. Urban dwelling may facilitate greater school-travel MVPA in adolescents. School-travel MVPA is an important contributor to adolescents' school-day MVPA. Where feasible, physically active options for school-travel should be promoted, including public transit.enAdolescentYouthHealth promotionTransportationPhysical activityEnvironmental designArticleSchool of Exercise Science, Physical and Health Education
