Highlights Non-linear and threshold effects of built environment were examined. Clarified associations of home and school environments with PA of children. Compared to differences of evidence in high-density and low-density contexts.

    Abstract The relationship between the built environment and the physical activity (PA) of children has been explored; however, the results remain controversial. Moreover, the studies on the non-linear influences of the built environment on PA are very limited. Using the 2019 questionnaire survey data from Xi'an, China, this study applies a gradient boosting decision tree (GBDT) model to explore the non-linear impact and the collective contribution of the urban built environment on the PA of children. The results showed that compared with demographics, the characteristics of the built environment are more important in predicting PA of children (58.8% vs 41.2%). Among the variables of the built environment that affect the PA of children, land-use mix around the school, the distance from home to school, and the distance to the nearest park are the top three important factors. A non-linear relationship exists between the specific built environment characteristics and the PA of children.
