摘要
应用横断面研究的方法通过单因素和 L ogistic回归分析对安徽省农村地区育龄妇女自然流产危险因素进行了探讨。结果发现 :安徽省农村地区育龄妇女 196 0～ 1993年间自然流产率为 7.6 5 % ,明显高于全国平均水平。单因素研究显示 :初婚年龄、生育年龄过高或过低 ,有自然流产史、人工流产史、不接受产前检查者自然流产率高 ;过短 (<8个月 )或过长 (>6 4个月 )的产孕间隔、高胎次均会加大自然流产发生的危险 ;妊娠期间高频率的被动吸烟、常于夜间工作、经常搬运重物或挑担可能是该农村地区育龄妇女自然流产的环境与职业危险因素。但生育年代、月经初潮年龄、避孕、孕期疾病、受教育程度、孕期从事弯腰的运动 (插秧、割麦、割稻、摘棉花、锄草等 )、农药接触及孕前配偶饮酒情况等与自然流产之间未见有相关关系存在。按胎次分层后的多因素分析显示 :除有自然流产史、过短产孕间隔及不接受产前检查外 ,其他经单因素分析筛选出的因素均失去其显著性。表明在该农村地区妊娠妇女中并不存在特别的自然流产职业性危险因素 ,但进一步抓好计划生育、杜绝多胎生育、加强孕期保健对降低自然流产率和促进妇女生殖健康将是有利的。
Based on the sectional investigation of woman's fertility and reproduction in rural areas of Anhui province,the paper studied the risk factors of miscarriage in the areas by the method of single variate analysis and multivariate logistic regression.The results are as follows:The spontaneous abortion rate in the areas from 1960 to 1993 is 7.65 percent,obviously higher than the average rate of China.Results from the singlevariate analysis indicated that older or younger marriage and birth age,prior spontaneous and induced abortion ,woman without prenatal checkup have higher spontaneous aborrtion rate.Shorter or longer birth spacing and more parities will increase the nanger of spontaneous abortion.Passive smoking with high density,more nightshift,more overloading or carrying appear to be the environmental and occupational risk factors of spontaneous abortion in the areas.But such factors as fertility ages, at menarche,contraception,diseases,educational level,work involving bending (for example,planting rice,cutting wheat and rice,picking cotton,mowing weeds,etc.)pesticide contact and partner alcohol consumption prior pregnancy ,etc.are not associated with an increased risk of spontaneous abortion.Results from multivariate model on parity classification indicated that the above risk factors have lost significance apart from prior spontaneous abortion,shorter birth spacing and no prenatal checkup.The paper show that there is no particular occupational risk factors of spontaneous abortion in these rural areas,but it is beneficial to further strengthen family planning,stop more birth and enhance pregnancy care for the reduction of spontaneous abortion rate and the improvement of reproduction health.
