目的：要研究的趋势，在使用长效可逆避孕（LARC）的方法，宫内节育器（IUD）和植入物，以及在何种程度上，这些方法已取代永久性绝育和不太有效的短效methods.Design：我们制表的数据从女性调查对象的整体和人口统计学亚组。我们对2007年和2009年使用LARC的女性避孕者比例的差异进行了t检验。我们还研究了LARC、绝育、其他方法的使用情况，以及在有意外怀孕风险的妇女中没有使用任何方法的情况。设置：家庭调查。患者：调查的所有女性受访者。干预措施：无。主要结果指标：2009年LARC方法的当前使用情况，以及2007年使用情况的变化。结果：使用LARC的避孕者比例从2002年的2.4%大幅增加到2007年的3.7%和2009年的8.5%。这一增长发生在几乎所有年龄、种族、教育和收入群体的妇女中。在妇女的意外怀孕的风险，增加LARC使用超过抵消减少sterilization.Conclusions（S）：LARC方法（主要是宫内节育器）在美国的避孕效果的增加作出贡献。（Fertil Steril（R）2012; 98：893 - 7.

Objective: To examine trends in the use of long-acting reversible contraceptive (LARC) methods-the intrauterine device (IUD) and implant-and the extent to which these methods have replaced permanent sterilization and less effective short-acting methods.Design: We tabulated data from female survey respondents overall and by demographic subgroups. We performed t-tests of the differences in the proportions of female contraceptors using LARC in 2007 and 2009. We also looked at use of LARC, sterilization, other methods, and no method among women at risk of unintended pregnancy.Setting: In-home survey.Patient(s): All female respondents to the surveys.Intervention(s): None.Main Outcome Measure(s): Current use of LARC methods in 2009, and change in use from 2007.Result(s): The proportion of contraceptors using LARC increased significantly from 2.4% in 2002 to 3.7% in 2007 and 8.5% in 2009. The increase occurred among women in almost every age, race, education, and income group. Among women at risk of unintended pregnancy, increases in LARC use more than offset decreases in sterilization.Conclusion(s): LARC methods (primarily IUDs) are contributing to an increase in contraceptive effectiveness in the United States.
