  • Title: Abortion and fertility control in Korea.
    Author: Kim OK.
    Journal: IPPF Med Bull; 1984 Apr; 18(2):6. PubMed ID: 12339511.
    Abstract:
    Findings are presented from a detailed study that used data from the 1974 Korean National Fertility survey to evaluate the impact of abortion on fertility and to investigate the interrelationships of abortion, contraceptive use, and contraceptive effectiveness in Korea. The relative effectiveness of contraception is low, the best being 76% effectiveness for women aged 30-34 in urban areas. Among women using contraception after abortion, the effectiveness is even lower. After the 1st abortion, 85% of the women aged 25-29 become pregnant with 2-5 years. 74% of women who use contraception after abortion become pregnant in this time compared to 92% of women who do not. Contraception when added to abortion achieves intervals that are twice as long as those for abortion alone. By using contraception, the interval from abortion to pregnancy is lengthened on average by 10.3 months for women aged 25-29, 11.5 months for those aged 30-34, and 9.3 months for those aged 35-39. The average number of abortions needed to avert a live birth in Korea is lower than the figure of 3.3 Potter estimated for societies with prolonged lactation. When contraception is not used, at least 1 abortion is needed each year to avert 1 live birth. With contraceptive use, the number of abortions needed to avert 1 live birth is between 0.55 and 0.62. The number of abortions needed in this case is greatly reduced when contraception is practiced more effectively. Comparing the actual level of contraceptive effectiveness in Korea in 1974 with a possible 95% effectiveness shows that this latter high level would have the same effect on fertility with approximately 6 fewer abortions throughout a woman's reproductive life. The actual reduction in numbers would be 5.8 in the 25-29 age group, 5.9 in the 30-34 age group, and 8.2 in the 35-39 age group. This reduction in the number of abortions necessary with 95% effective contraception as compared with actual contraceptive use, suggests considerable potential for reducing the need for additional abortions with improved contraception. The current situation has improved since 1974, due to the success of the sterilization program.
