孕妇沙眼衣原体感染危险因素的研究

Epidemiological Study on Risk Factors of Chlamydia Trachomatis Infection in Pregnant Women

用间接血凝试验检测沙眼衣原体抗体。对 54例沙眼衣原体感染孕妇和 2 16名无感染的孕妇进行了 1∶ 4配比病例对照研究。单因素分析 ,从 2 6个研究因素中筛选出 8个与感染有联系的因素。多因素条件 logistic回归分析 ,最终选入模型的有 4个因素 :婚外性行为、泌尿生殖道感染史、首次性交年龄及未避孕或宫内避孕。

Pregnant women and2 16without were detected for anti- Chlamydial antibodies, using indirect hemagglutination test on a1∶ 4 matched Case- control study to look for risk factors of Chlamydia trachomatis infection.A total number of2 6independent variables were selected for analysis,in which8factors were comfirmed as associatied factors by single variable analyisis.Of the above8factors,4 were significantly correlated to the infection under the multifactorial conditional logistic regression model,which were:extramarital sex life,history of urogenital tractinfection,age of sexual intercourse debut and the use of intrauterus contraception.
