Between 1982 and 1987, favorable opinion of the pill increased steadily among American women (from 65 to 76 percent), and favorable opinion of the condom rose sharply (from 38 to 60 percent). Approval of the IUD dropped during the period (from 26 percent to 19 percent). During the five years, the proportion of married women aged 18-44 who were exposed to the risk of unintended pregnancy remained the same (78 percent), but the proportion among unmarried women rose significantly (from 64 percent to 69 percent). This change was primarily the result of an increase--from 68 percent to 76 percent--in the proportion of never-married women who had ever had intercourse. The overall level of contraceptive use among 18-44-year-olds who were exposed to risk remained stable over the period, at about 93 percent, but use of the most effective methods (sterilization, pill and IUD) went up, from 68 percent to 71 percent. All of the net increase in effective-method use, however, was limited to married women, among whom reliance on both sterilization and the pill increased (from 46 to 51 percent and from 17 to 22 percent, respectively). Pill use also rose among unmarried women (from 43 to 48 percent), but there was no change in the level of sterilization. The prevalence of IUD use declined among both married and unmarried women (to three percent in each case). Condom use remained steady among married women, at about 15 percent, but among the unmarried it increased markedly, from nine to 16 percent.(ABSTRACT TRUNCATED AT 250 WORDS)
1982年至1987年间,美国女性对避孕药的好感度稳步上升(从65%升至76%),对避孕套的好感度则大幅提高(从38%升至60%)。在此期间,对宫内节育器的认可度有所下降(从26%降至19%)。在这五年中,18至44岁面临意外怀孕风险的已婚女性比例保持不变(78%),但未婚女性中的这一比例显著上升(从64%升至69%)。这一变化主要是由于从未结婚但有过性行为的女性比例从68%增至76%。在此期间,18至44岁面临风险人群的总体避孕使用率保持稳定,约为93%,但最有效的避孕方法(绝育、避孕药和宫内节育器)的使用率有所上升,从68%升至71%。然而,有效避孕方法使用的净增长仅限于已婚女性,她们对绝育和避孕药的依赖程度均有所增加(分别从46%升至51%和从17%升至22%)。未婚女性中避孕药的使用也有所增加(从43%升至48%),但绝育使用率没有变化。已婚和未婚女性中宫内节育器的使用率均有所下降(均降至3%)。已婚女性中避孕套的使用率保持稳定,约为15%,但未婚女性中避孕套的使用率显著上升,从9%升至16%。(摘要截选至25
