Introduction – Using the pregnancy outcome certificate (CIG), specific to the Maternal and Child Health (PMI) service in Seine-Saint-Denis (SSD), this study aims to assess trends from 2012 to 2022, the recorded total stillbirth rates and their components (spontaneous and induced by medical termination of pregnancy (IMG)), by comparing them to the national trend, and secondarily to compare the characteristics of stillborn infants from the years 2012–2013 and 2021–2022.Materials and Methods – The study included all stillbirths occurring in SSD maternity wards from 2012 to 2022, from 22 weeks of amenorrhea onward, as recorded in the CIG. Temporal trends in total, spontaneous, and induced stillbirth rates were analyzed using the Mann-Kendall test and compared with national data. The characteristics of stillbirths were compared between the years 2012–2013 and 2021–2022 using Fisher’s exact test and the chi-square test. Municipal maps of total stillbirth rates were created using Esri’s ArcGIS Pro® software. Results – A total of 2,470 stillbirths were recorded. Stillbirth rates decreased over the period, with no significant overall trend. A significant decrease in total and induced stillbirth rates was observed between 2012 and 2019, followed by an increase beginning in 2020. The rates remained higher than national levels. The average maternal age increased, the proportion of induced medical abortions (IMAs) performed for psychosocial reasons rose, and those performed due to fetal malformations and infections decreased. Mapping analyses showed a decrease in stillbirth rates in more than half of the municipalities. Conclusion—Stillbirth rates recorded in the SSD remain stable despite an initial decline, linked to persistent adverse social factors. The CIG provides essential local data to guide interventions.
