To understand the current status of abortion and contraception among nonparous adolescent women and explore the influence of post-abortion care (PAC) services on their contraceptive choice and repeated abortion.

A retrospective study was conducted on the nonparous adolescent women who had undergone induced abortion in outpatient clinics of Guangdong Women's and Children's Hospital from January to December 2018 was recruited. Through PAC consultation and follow-up, their contraceptive options and the incidence of repeated abortions before and after surgery were compared.

1) There were 1137 cases of induced abortion among nonparous adolescent women, accounting for 85.30% (1137/1333) of the total number of adolescent abortions, 29.51% (1137/3853) of the total number of abortions during the same period, among which 23.39% (266/1137) had abortion history before surgery, 5.54% (63/1137) had abortion ≥3 times, 2.73% (31/1137) had repeated abortion (≥2 times within 1 year) within half a year, and 6.86% (78/1137) had abortion ≥2 times within 1 year. 2) There was a significant increase in the choice of high-efficiency contraceptive methods after PAC compared with that before surgery (2.73% vs. 84.43%,P<0.001), in which the use of combined oral contraceptive (COC) and intrauterine device (IUD) increased significantly (2.73%vs. 83.46%, P<0.001; 0vs. 0.97%,P=0.001), and the number of married women using IUD was higher than that of unmarried women (5.71%vs.0.86%,P=0.047). On the other hand, the rate of continued use of COC at 3, 6, and 12 months of post-operative nonparous adolescent women gradually decreased (83.01%, 5.95%, 2.46%), while the rate of continued use of IUD remained stable (0.97%, 1.14%, 1.23%). 3) The repeated induced abortion rate among nonparous adolescent women in the half of a year and one year after PAC significantly decreased compared with that before PAC (1.26%vs. 2.73%, P=0.022; 3.70%vs. 6.86%, P=0.003).

Nonparous adolescent women have a higher rate of repeated abortions, while a lower rate of the use of high-efficiency contraceptive methods. PAC services can significantly improve the immediate implementation rate of high-efficiency contraceptives, and it is necessary to further increase the immediate implementation rate of IUD and the continued use rate of the COC.
