To study the current status and risk factors of spontaneous abortion of women at reproductive age in rural areas of Shaanxi province.
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.
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 > or =30 years and those with more than 3 pregnancies.
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.
研究陕西省农村育龄妇女自然流产的现状及危险因素。
对居住在陕西省长武县和彬县的孕妇进行访谈，了解其既往生育史，并对2002年至2005年的妊娠结局进行随访。
共纳入5844名孕妇，妊娠总数9638次，其中自然流产1153例。陕西省农村地区孕妇中，自然流产与妊娠次数之比为12.0%，自然流产率（SAR）为13.6%。自然流产妇女数与被调查妇女总数之比为16.4%。年龄≥30岁及妊娠3次以上的妇女发生自然流产的风险会增加。
为降低农村地区妇女自然流产的发生率，应采取的措施包括：加强计划生育管理，减少妊娠次数，延长妊娠间隔，避免高龄妊娠。
