Active commuting to school could help increasing physical activity levels among adolescents. However, there is limited understanding on how the relationship between the environment in school surroundings, as well the distance to school, could affect this behavior.
To analyze the characteristics of the environment and distance between house and school with objective measures and their association with active commuting between adolescents of Curitiba, Brazil.
493 adolescents were interviewed and 124 schools evaluated. The study variables included the schools' surroundings accessibility characteristics obtained through systematic observation, and the distance between home to school was determined through Geographic Information Systems (GIS) data.
The presence of "safety signs" was inversely associated with active commuting (PR = 0.78; 95%CI 0.67-0.91; p = 0.003), as well distance 1,501-3,000 m (PR = 0.53; 95%CI 0.40 - 0.71; p < 0.001) and ≥ 3,501 m (PR 0.29; 95%CI 0.18 - 0.45; p < 0.001). Overall, schools' surroundings showed walking friendly characteristics.
Traffic safety and distance to school were associated with active commuting to school among the study participants. Policies aiming at integrating access to school and traffic safety could help to promoting active commuting among adolescents.
积极步行或骑行上学有助于提高青少年的身体活动水平。然而，对于学校周边环境与学校距离之间的关系如何影响这种行为，我们的了解还很有限。
通过客观测量分析学校周边环境特征以及家与学校之间的距离，并探讨它们与巴西库里蒂巴青少年积极通勤之间的关联。
对493名青少年进行了访谈，并对124所学校进行了评估。研究变量包括通过系统观察获得的学校周边可达性特征，以及通过地理信息系统（GIS）数据确定的家到学校的距离。
“安全标志”的存在与积极通勤呈负相关（PR = 0.78；95%CI 0.67 - 0.91；p = 0.003），距离在1501 - 3000米之间（PR = 0.53；95%CI 0.40 - 0.71；p < 0.001）以及≥3501米（PR = 0.29；95%CI 0.18 - 0.45；p < 0.001）时也是如此。总体而言，学校周边环境呈现出适合步行的特征。
交通安全和学校距离与研究参与者积极步行或骑行上学有关。旨在整合上学便利性和交通安全的政策有助于促进青少年积极通勤。
