目标。我们监测了2001-2008年间全国范围内和关键亚组的意外妊娠的强度和结局。来自全国家庭增长调查(NSFG)和具有全国代表性的堕胎患者调查的怀孕意向数据与出生计数(来自国家卫生统计中心)、堕胎计数(来自堕胎提供者普查)、流产估计数(来自NSFG)和美国人口普查局的人口分母相结合，以获得怀孕率。2008年，美国51%的怀孕是意外的，意外怀孕率为每1000名15岁至44岁的妇女中有54人。2001至2008年间，预期怀孕人数减少，意外怀孕人数增加，这是以前从未观察到的转变。意外怀孕在婚姻状况、收入和受教育程度方面的巨大差异增加；意外怀孕以流产结束的比例下降；意外怀孕以分娩结束的比例上升，达到每1000名妇女中有27人。减少意外怀孕可能需要解决根本的社会经济不平等，以及增加避孕用具的使用和采用高效的方法。
Objectives. We monitored trends in pregnancy by intendedness and outcomes of unintended pregnancies nationally and for key subgroups between 2001 and 2008.Methods. Data on pregnancy intentions from the National Survey of Family Growth (NSFG) and a nationally representative survey of abortion patients were combined with counts of births (from the National Center for Health Statistics), counts of abortions (from a census of abortion providers), estimates of miscarriages (from the NSFG), and population denominators from the US Census Bureau to obtain pregnancy rates by intendedness.Results. In 2008, 51% of pregnancies in the United States were unintended, and the unintended pregnancy rate was 54 per 1000 women ages 15 to 44 years. Between 2001 and 2008, intended pregnancies decreased and unintended pregnancies increased, a shift previously unobserved. Large disparities in unintended pregnancy by relationship status, income, and education increased; the percentage of unintended pregnancies ending in abortion decreased; and the rate of unintended pregnancies ending in birth increased, reaching 27 per 1000 women.Conclusions. Reducing unintended pregnancy likely requires addressing fundamental socioeconomic inequities, as well as increasing contraceptive use and the uptake of highly effective methods.
