摘要
目的：了解中国的流产水平和变化趋势。方法利用全国妇幼卫生年报所收集到的1990—2012年的活产数、人工流产数和1996—2012年的死胎死产数，估计年度自然流产数和怀孕人数，计算年度人工流产﹣活产比和流产比例。结果中国1990—1994年的人工流产活产比在0．8以上，1995—2008年在0．5～0．8，2009年开始下降到0．5以下；中国1996—2008年的人工流产比例约在1／3，2009年开始下降到1／4左右。避孕失败率高和计划生育服务未惠及到所有应该服务的对象可能是中国人工流产水平高的主要原因。结论中国近年的人工流产水平有所下降，但仍然较高。
Objective To obtain the prevalence and trends of induced abortion in Chinese women from 1990 to 2012. Methods Data on live﹣births and induced﹣abortions from 1990 to 2012 and stillbirths from 1996 to 2012 were obtained from the national child and maternal health yearly report system;annual numbers of spontaneous miscarriage and total pregnancies were estimated;and the induced﹣abortion to live﹣birth ratios and annual percentage of pregnancies ending in abortion were calculated. Results The induced﹣abortion to live﹣birth ratio was above 0.8 during 1990 to 1994, ranging from 0.5 to 0.8 during 1995 to 2008,and declined to below 0.5 in 2009 and onward.The percentage of pregnancies ending in induced abortion was around one﹣third during 1996 to 2008,and decreased to near one﹣fourth since 2009. Conclusion Although induced abortion in Chinese women showed a declining trend,the prevalence remained high.Contraception failure and unmet need for family planning services may be the primary reasons.
