Nationwide evidence from China on the dose-response between environmental fitness support and physical activity.

ABSTRACT: This study aims to investigate the relationship between Environmental Fitness Support (EFS) scores and physical activity (PA), analyzing the non-linear and dose-response relationships between fitness environment support and different intensities of PA, as well as the impact of various environmental dimensions on PA intensity. Using data from the 2020 China National Fitness Activity Status Survey, a multi-stage stratified random sampling method was employed to select 5,760 village (resident) committees from 31 provinces, yielding 58,844 valid samples. The survey collected demographic information and environmental support factors (EFS scores), and used the International Physical Activity Questionnaire to measure PA intensity. Statistical analyses were conducted using R software, including mu
