陕西省咸阳地区贫困农村育龄妇女自然流产状况调查

Study on the current status and risk factors of spontaneous abortion of women at reproductive age in rural areas of Xianyang district, Shaanxi province

目的了解陕西省贫困农村育龄妇女自然流产状况及其相关因素。方法于2002—2005年间对陕西省长武县、彬县的农村怀孕妇女进行入户访问获得孕产妇的既往生育史，并对孕妇进行随访，直至获得本次妊娠结局。结果共随访5844例孕产妇，总妊娠次数为9638次，其中1153次为自然流产。孕产妇自然流产妊娠比为12．0％，自然流产率为13．6％，发生自然流产的比例为16．4％。随着妇女年龄的增加、妊娠次数的增加等，育龄妇女发生自然流产的危险性也在增加。结论加强计划生育，减少妊娠次数，延长生育间隔，防止高龄怀孕将有助于降低陕西省贫困农村育龄妇女自然流产的发生水平。

Objective To study the current status and risk factors of spontaneous abortion of women at reproductive age in rural areas of Shaanxi province. Methods Pregnant women who lived in Changwu and Bin counties of Shaanxi province were interviewed on their former reproductive history and being followed on the outcomes of pregnancy from 2002 to 2005. Results There were 5844 pregnant women under study with a total number of 9638 pregnancies including 1153 spontaneous abortive episodes. Among the pregnant women in rural areas of Shaanxi province, the ratio between spontaneous abortion and pregnancies was 12.0% and the spontaneous abortion rate（SAR） was 13.6 %. Ratio between the number of women who had experienced spontaneous abortion and the total number of women under survey was 16.4 %. The risks of having spontaneous abortion would increase among women who were aged ≥30 years and those with more than 3 pregnancies. Conclusion To reduce the incidence of spontaneous abortion among rural area women, the approaches should include： strengthening the family planning management, reducing of the frequency of pregnancy, extending the pregnancy interval and avoiding advanced ageing pregnancies.
