定期估计全球意外怀孕的发生率有助于证明计划生育计划的必要性和影响。我们利用多种来源的数据来估计2012年全球、区域和次区域各级的怀孕意向、状况和结局，并使用先前公布的2008年和1995年的估计数来评估最近的趋势。我们发现，2012年发生了2.13亿例怀孕，略高于2008年的2.11亿例。全球怀孕率在1995年至2008年大幅下降后，从2008年至2012年仅略有下降。2012年有8500万例意外怀孕，占所有怀孕总数的40%。其中，50%以堕胎告终，13%以流产告终，38%以计划外生育告终。非洲以及拉丁美洲和加勒比地区的意外怀孕率继续下降。如果伦敦计划生育首脑会议的目标得以实现，意外怀孕和不合时宜怀孕的发生率在未来几年应该会下降。
Periodic estimation of the incidence of global unintended pregnancy can help demonstrate the need for and impact of family planning programs. We draw upon multiple sources of data to estimate pregnancy incidence by intention status and outcome at worldwide, regional, and subregional levels in 2012 and to assess recent trends using previously published estimates for 2008 and 1995. We find that 213 million pregnancies occurred in 2012, up slightly from 211 million in 2008. The global pregnancy rate decreased only slightly from 2008 to 2012, after declining substantially between 1995 and 2008. Eighty-five million pregnancies, representing 40 percent of all pregnancies, were unintended in 2012. Of these, 50 percent ended in abortion, 13 percent ended in miscarriage, and 38 percent resulted in an unplanned birth. The unintended pregnancy rate continued to decline in Africa and in the Latin America and Caribbean region. If the aims of the London Summit on Family Planning are carried out, the incidence of unwanted and mistimed pregnancies should decline in the coming years.
