Results From 2010 to 2019, the proportion of induced abortion cases with advanced maternal age in the total induced abortion cases was 14.56%, and year of 2014 was the cut-off point of induced abortion for cases with advanced maternal age, the lowest rate was 10.73% in 2013 and the highest was 21.73% in 2019. The ratio of multiple induced abortion cases with advanced maternal age decreased year by year, from the highest ratio of 25.99% in 2014 to 11.19% in 2019. There were significant differences in the average numbers of vaginal delivery and cesarean section in multiple induced abortion cases with advanced maternal age between different years(P<0.01). Among the multiple induced abortion cases with advanced maternal age, there were significant differences in household register, education level, occupation, marital status, times of vaginal delivery and cesarean section(P<0.01). Except for choice of subcutaneous implantation, there was a significant difference in the selection of contraceptive methods before and after education in multiple induced abortion cases with advanced maternal age(P<0.01). Conclusion The abortion rate of women with advanced maternal age in our hospital is increasing year by year, which is not - only related to their low educational level and lack of contraceptive knowledge, but also related to their special physiological stage and complicated diseases.
