What this Trial Is About
This research aims to evaluate how previous induced termination of pregnancy affects complications and outcomes in later pregnancies. It is a prospective multicenter cohort study focused on reproductive health and abortion. The study seeks to understand the relationship between early pregnancy terminations and future pregnancy risks to improve knowledge in this area. Participants are women who have experienced an induced abortion within the first 12 weeks of pregnancy. The study observes these women over time without providing any experimental treatment, focusing on medical or surgical termination of pregnancy as the prior event. There are no intervention groups as this is an observational study. During the study, participants will be monitored for complications and adverse pregnancy outcomes. Researchers will collect data through follow-up investigations and evaluate pregnancy progress and health status. The primary outcome is adverse pregnancy outcomes reviewed by June 2028, with complications also tracked. Participation includes providing informed consent and cooperating with follow-ups over the study period.
