in its infant mortality rate of decline. Prenatal care was increasingly used, even as the Cooperative Medical System was replaced, and delivery assistance remained accessible. China's one-child policy, adopted in the 1980s, negatively impacted its infant mortality. Women carrying unapproved pregnancies faced state consequences and social stigma and were thus less likely to use prenatal care. Additionally, economic realities and long-held cultural factors incentivized male offspring, leading some families who already had sons to avoid prenatal care or professional delivery services, and causing China to have unusually high female infant mortality rates during this time.
