Environmental greenness, physical activity, and their synergistic effects on vital capacity weight index in children and adolescents exposed to PM_2.5 and O₃ in economically developed provinces of China.

ABSTRACT:

Background

The Vital Capacity Weight Index (VCWI) serves as a pivotal indicator of cardiopulmonary function among children and adolescents, reflecting their tissue oxygenation capacity and athletic potential. This study delves into the influence of environmental greenness and physical activity on VCWI in children residing in China's economically prosperous provinces, who are exposed to air pollutants, namely PM_2.5 and O₃.

Methods

We performed a cross-sectional analysis using data from the 2019 Chinese National Survey on Students' Constitution and Health (CNSSCH), involving 62,987 students from the top eight provinces by GDP. Exposure to PM_2.5 and O₃ was estimated using data from the Tracking Air Pollution in China (TAP) platform. G
