The impact of physical exercise, health effect, and harmony effect on young adults’ fertility attitudes: a study based on empirical analysis of 2023 CGSS data

The findings confirm that physical exercise is a significant and positive predictor of fertility attitudes in China. The mechanisms operate through both bio-psychological and socio-familial channels. We conclude that public policies aimed at promoting accessible and appealing physical exercise can effectively complement existing fertility support measures, thereby providing a viable strategy to help optimize China's national population policies.
