The prevalence of barriers to rearing children aged 0-3 years following China's new three-child policy: a national cross-sectional study.

The prevalence of barriers to rearing children aged 0-3 years was high among Chinese people of childbearing age who had children. Full consideration should be given to the barriers of people with different sociodemographic characteristics and people with fertility intention, thus making targeted childrearing policies and supporting measures to reduce the burden on people of childbearing age, encourage suitable couples to have a second or third child and then cope with China's aging population.
