Abstract: Objective  To analyze the preferences of women of childbearing age for preconception health care services and provide insights for optimizing the reproductive health system and enhancing their willingness to have children. Methods  A discrete choice experiment questionnaire was developed based on a literature review and semi-structured interviews. It identified five key factors influencing preconception health care preferences: hospital level, examination content, offer form, integrated service form, and distance to the examination location. Using convenient sampling, women of childbearing age in Beijing were surveyed. The sample‘s measurement information was analyzed using mean (standard deviation) and count information with frequency (composition ratio). Preferences and their interaction with demographic information were analyzed using a mixed logistic model. Results  Out of 356 questionnaires, 329 were valid (92.4% effective rate). The survey showed 84.8% of respondents were under 35, and 74.8% lived in the city. Women preferred services close to their location (β=-0.636, P<0.01), including 19 basic examinations with education on diet, exercise, and psychology (β=0.611, P <0.01), home guidance (β=0.410, P<0.01), combined with premarital examinations (β=0.225, P <0.01), and offered by level-three hospitals (β=0.104, P=0.089). Women in rural areas preferred home guidance and proximity, while those with previous pregnancies preferred genetic testing. Conclusions Women of childbearing age in Beijing prioritize the distance to the examination location and the examination content when choosing preconception health care services. Preferences vary with demographic characteristics. Recommendations include increasing publicity, strengthening policy guidance, planning services tailored to contemporary women, reducing the distance to examination sites, and promoting guidance on diet, exercise, and psychology during pregnancy.
