To promote the use of long-acting reversible contraceptive (LARC) methods (intrauterine devices [IUDs] and implants) and provide contraception at no cost to a large cohort of participants in an effort to reduce unintended pregnancies in our region.
We enrolled 9,256 adolescents and women at risk for unintended pregnancy into the Contraceptive CHOICE Project, a prospective cohort study of adolescents and women desiring reversible contraceptive methods. Participants were recruited from the two abortion facilities in the St. Louis region and through provider referral, advertisements, and word of mouth. Contraceptive counseling included all reversible methods but emphasized the superior effectiveness of LARC methods (IUDs and implants). All participants received the reversible contraceptive method of their choice at no cost. We analyzed abortion rates, the percentage of abortions that were repeat abortions, and teenage births.
We observed a significant reduction in the percentage of abortions that were repeat abortions in the St. Louis region compared with Kansas City and nonmetropolitan Missouri (P<.001). Abortion rates in the CHOICE cohort were less than half the regional and national rates (P<.001). The rate of teenage birth within the CHOICE cohort was 6.3 per 1,000, compared with the U.S. rate of 34.3 per 1,000.
We noted a clinically and statistically significant reduction in abortion rates, repeat abortions, and teenage birth rates. Unintended pregnancies may be reduced by providing no-cost contraception and promoting the most effective contraceptive methods.
推广长效可逆避孕方法(宫内节育器[IUD]和植入物)的使用,并为大量参与者提供免费避孕服务,以努力减少本地区的意外怀孕。
我们将 9256 名青少年和有意外怀孕风险的妇女纳入避孕选择项目(Contraceptive CHOICE Project),这是一项针对希望采用可逆避孕方法的青少年和妇女的前瞻性队列研究。参与者是从圣路易斯地区的两家堕胎机构以及通过医生推荐、广告和口碑招募的。避孕咨询包括所有可逆方法,但强调长效可逆避孕方法(IUD 和植入物)的卓越效果。所有参与者都免费获得他们选择的可逆避孕方法。我们分析了堕胎率、重复堕胎的百分比以及青少年怀孕率。
与堪萨斯城和非都市密苏里州相比,我们观察到圣路易斯地区重复堕胎的百分比显著下降(P<.001)。CHOICE 队列的堕胎率低于该地区和全国的堕胎率(P<.001)。CHOICE 队列中的青少年出生率为每 1000 名 6.3 例,而美国的出生率为每 1000 名 34.3 例。
我们注意到堕胎率、重复堕胎率和青少年出生率都有临床和统计学上的显著降低。通过提供免费避孕服务和推广最有效的避孕方法,可能会减少意外怀孕。
