Contraceptive practice before and after therapeutic abortion. II. Use-effectiveness of oral contraceptives and intrauterine devices.
Of 180 women who underwent therapeutic abortion in a certain period in 1977, 71.7% were unmarried and 63.9% were unmarried primigravidas. At the first follow-up visit 3 to 6 weeks postabortion 55.0% of the unmarried primigravidas chose oral contraceptives and 43.2% chose intrauterine devices (IUDs). Of the unmarried women, 25.7% chose oral contraceptives and 65.7% chose IUDs. For unmarried primigravidas the 1-year continuation rates for oral contraceptives and IUDs were 83.6% and 93.8%, respectively. For married women the figures were 55.6% for oral contraceptives and 91.3% for IUDs. The differences between use of oral contraceptives and use of IUDs in the two groups of women was not statistically significant. We recorded no contraceptive failure, but three episodes of pelvic inflammatory disease occurred among unmarried primigravidas. The results indicate a high motivation for reliable methods and a high continuation rate following therapeutic abortion. The results may also indicate that oral contraceptives and IUDs represent equivalent methods for both parous and nulliparous women.
