ABSTRACT=Background: A large number of high-income countries are now promoting active commuting to school as an opportunity for adolescents to increase physical activity (PA) and improve their health. Few studies have examined the multiple benefits of active travel to school among adolescents in developing countries, especially in China. Hence, this study to estimate the causal effects of bicycling to school on adolescents’ subjective health, physical health, and sickness absence.

Methods: Self-reported and cross-sectional data from 6353 school-aged children (12-19 years old) in the 2014-2015 China Education Panel Survey (CEPS2014-2015) were used. The independent variable was a binary, self-reported indicator of whether children bicycled to school. The dependent variables included subjective health (self-reported health, mental stress), physical health (BMI, kidney disease, lung disease, heart disease, brain disease, upper limb fracture, lower limb fracture, and sickness frequency), and sickness absence. Propensity score matching (PSM) was used to estimate the causal effects of bicycling to school on adolescents’ health. 

Results: Bicycling to school positively affects both subjective and physical health. Those students who biked to school were associated with a higher self-rated health status, a healthier weight, a lower level of mental stress, and a lower risk of developing brain diseases. No significant relation is found between bicycling and sickness frequency, and sickness absence. Differentiation of the health effects of bicycling across living areas shows that health effects are more pronounced for those living in edge and rural areas. 
Conclusion: These findings provide evidence of the value of promoting bicycling to school in improving various adolescents’ health outcomes in transitional China.
