Adolescents from low socioeconomic status (SES) & migrant-background families → less physically active (Owen et al. 2022; Ahmed et al. 2021; Lorente et al. 2025; Boraita et al. 2022).
Active commuting to school (ACS) (walking/cycling) → cheap, accessible, parent-independent → may reduce gaps
In Southern Europe, little evidence on ACS by social group & neighbourhood environment
RQ1. Do Spanish low-SES and migrant-background adolescents differ in ACS vs peers?
RQ2. If so, do neighbourhood environments explain or amplify these differences?
Cross-sectional study
366 urban adolescents (13–17y, Spain)
PACO project (Chillón et al. 2021)
Outcomes: usual mode (active vs passive); weekly active trips
Predictors: sociodemographics (SES, migration background, age, gender); environmental factors (distance to school, residential density, land-use mix, pedestrian infrastructure, perceived environment)
Multilevel regression (students nested in schools)
ACS higher among low-SES and migrant-background adolescents
Low-SES and migrant-background adolescents live closer to school
Truncated at 30 km.
Social ACS differences to school ➡️🏫 mostly explained by distance
OR = Odds Ratio (odds of using active vs passive mode). ➡ OR < 1 = ↓ less likely | OR > 1 = ↑ more likely.
IRR = Incidence Rate Ratio (number of weekly active trips). ➡ IRR < 1 = ↓ trips | IRR > 1 = ↑ more trips.
Models adjusted for age & gender.
Stronger social ACS differences from school ⬅️🏫, also mostly explained by distance
➡ OR < 1 = ↓ less likely | OR > 1 = ↑ more likely.
➡ IRR < 1 = ↓ trips | IRR > 1 = ↑ more trips.
Models adjusted for age & gender.
RQ1. Do Spanish low-SES and migrant-background adolescents differ in ACS vs peers? → Yes. They engage more in ACS, especially from school.
RQ2. Do neighbourhood environments explain or amplify these differences? → Explain. Once adjusted for environment, SES and migration differences disappear.
The disparities appear to be less about who adolescents are and more about where they live — with distance to school playing the biggest role
Protective mechanism: ACS in Spain helps reduce social gaps in PA — but only where schools are close enough to walk.
Policy priority: School siting and neighbourhood planning are crucial to sustain equity in PA.
