沿奎河地区妇女自然流产流行状况及其影响因素

Current status and influencing factors of spontaneous abortion of women along Kui River

目的 了解沿奎河地区妇女自然流产状况及其影响因素。方法 于2012年至2013年对沿奎河地区40~70岁妇女进行问卷调查,获得生育史和相关影响因素。结果 共调查4 438名妇女,总妊娠次数为14 418次,自然流产次数587次。自然流产妊娠比、自然流产率和自然流产妇女所占比例分别为4.07%、4.40%、10.23%。多因素分析显示,孕前被动吸烟（OR=1.28,95%CI：1.03~1.61）、孕前饮酒（OR=1.33,95%CI：1.01~1.77）、做饭时厨房油烟量（OR=1.44,95%CI：1.08~1.92）、平时容易生气（OR=1.46,95%CI：1.16~1.84）、睡眠状况不好（OR=1.37,95%CI：1.07~1.74）会增加妇女自然流产的发生风险。怀孕次数是发生自然流产的重要原因,随着怀孕次数的增加,妇女发生自然流产的风险增加,孕次〉3次者发生自然流产的风险最大（OR=31.54,95%CI：17.88~55.64）。结论 奎河地区妇女自然流产率较高,孕前被动吸烟、孕前饮酒、做饭时厨房油烟量大、平时容易生气、睡眠状况不好、怀孕次数多是妇女发生自然流产的危险因素。

Objective To study the status and influencing factors of spontaneous abortion of women along Kui River. Methods Women aged 40-70 along Kui River were interviewed on their reproductive history and related influencing factors from 2012 to 2013. Results There were 4 438 women in the study with a total number of 14 418 pregnancies, including 587 spontaneous abortive episodes. Ratio between spontaneous abortion and pregnancies was 4.07%, spontaneous abortion rate （SAR） was 4.40%, and the proportion of women who had experienced spontaneous abortion accounted for 10.23%. Logistic regression analysis indicated that passive smoking prior to pregnancy, drinking before pregnancy, amount of lampblack in cooking, being easy to get angry and poor sleep would increase the risk of spontaneous abortion （OR value was 1.28, 1.33, 1.44, 1.46 and 1.37, respectively, and 95%CI ranged 1.03-1.61, 1.01-1.77, 1.08-1.92, 1.16 - 1.84 and 1.07 - 1.74, respectively）. Number of pregnancy was the important cause of spontaneous abortion. With the increase of the number of pregnancies, the risk of spontaneous abortion would increase. The women who had more than 3 pregnancies had the highest risk of spontaneous abortion （ OR = 31.54,95 % CI： 17.88 -55.64）. Conclusion The spontaneous abortion rate of women along Kui River is high. The risk factors of spontaneous abortion include passive smoking, drinking before pregnancy, large amount of lampblack in cooking, being easy to get angry and poor sleep status.
