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.
1977年某一时期接受治疗性流产的180名女性中，71.7%未婚，63.9%为未婚初孕妇。在流产后3至6周的首次随访中，55.0%的未婚初孕妇选择口服避孕药，43.2%选择宫内节育器（IUD）。在未婚女性中，25.7%选择口服避孕药，65.7%选择宫内节育器。对于未婚初孕妇，口服避孕药和宫内节育器的1年持续使用率分别为83.6%和93.8%。对于已婚女性，口服避孕药和宫内节育器的数字分别为55.6%和91.3%。两组女性在口服避孕药和宫内节育器使用方面的差异无统计学意义。我们未记录到避孕失败情况，但未婚初孕妇中有3例发生盆腔炎。结果表明对可靠避孕方法的积极性高，治疗性流产后的持续使用率也高。结果还可能表明口服避孕药和宫内节育器对经产妇和未产妇来说是等效的避孕方法。
