Abstract

Background Cardiorespiratory fitness (CRF) has been investigated as a broad, holistic health indicator for children and adolescents. The adverse effects of particulate matter on lung function and cardiovascular health have been widely reported, whereas the association between particulate matter and CRF and its potential pathways remains unclear. The study aims to estimate the association between particulate matter and CRF in children and adolescents and the mediating effect of adiposity on this association. Methods A multistage random cluster sampling method was used to obtain a nationwide sample of 99 995 children and adolescents in China. Daily exposure to particulate matter with aerodynamic diameter ≤2.5 and
