Therefore, this article introduced and extended the concept of "healthy birth"; analyzed the main health problems and challenges in this field, such as the sustained fall of birth population, the fecundity decline among couples at reproductive age, advanced maternal age and severe complications during pregnancy, birth defects, female malignant tumor and fertility preservation, and threats from emerging major infectious disease; and then discussed the medium-term and long-term development layout and planning in the field of healthy birth, covering the aspects of population policy, basic research, clinical research, discipline layout and collaborative innovation, so as to protect health from the origin of life and ensure the high-quality development of population health.
