Abstract: Delayed childbearing has been found detrimental to children's health. While post-transitional China is observing a substantial increase of childbearing postponement, this study aims to investigate health impact of this trend on the next generation. Using data from the 2010-2020 China Family Panel Studies（CFPS）, this study examines the multidimensional health differences related to both maternal and paternal ages in post-transitional China. The results show that delayed childbearing contributes negatively to children's birth weight, their physical development in childhood, and general health in adolescence. These health impacts operate partly through congenital factors, as manifested in the greater risk of low birth weight, and partly via the related family environments and resources. These findings highlight the need to incorporate health considerations into decisions about childbearing, both for health promotion and for sustained population development.
