: Ethical approval for the study was obtained from the Ethics Review Committee of the Jiangsu Province Hospital (2023-SR-012). Informed consent was obtained from all subjects involved in the study. Participants were informed of our research topic and related information. At the beginning of each interview, the researcher gave the participant a consent form and asked her to read it carefully. If the participant agreed to its terms, she signed it; if not, the interview was terminated, and we moved to the next interviewee (for illiterate participants, informed consent was obtained from their husband). Participants’ private information was only used for scientific records, kept confidential from the public and collated anonymously to prevent identification. All methods were performed in accordance with the relevant guidelines and regulations.
