城镇妇女宫颈上皮内瘤变高危因素流行病学调查

将2006月7月至2007年8月在门诊开展宫颈癌机会性筛查确诊为宫颈上皮内瘤变（CIN）122例患者作为调查对象（CIN组），并取同期宫颈炎症患者122例作对照组，开展流行病学问卷调查。结果表明，72％的妇女2年内未做过宫颈癌筛查；55％的妇女有婚前性行为；CIN发病高峰集中在30～34岁；75％的CIN是通过机会性筛查确诊；CIN组初次性交年龄早、早婚、早育、多次妊娠、多次流产者明显高于对照组（P〈0．05）。提示加强门诊宫颈癌机会性筛查，扩大受益人群比改进筛查技术更重要．

Epidemiological survey of high risk factors for cervical intraepithelial neoplasia in women

One hundred and twenty-two patients with confirmed cervical intraepithelial neoplasia (CIN), as a result of occasional screening for uterine cervix cancer in our out-patient clinic between July 2006 and August 2007, and 122 control patients with cervicitis who received colposcopy during the same period were enrolled in this study. Our results showed that 72% participants didn't receive uterine cervix cancer screening during the past 2 years; 55% women had premarital sexual behavior. CIN was most commonly seen in 30 to 34 year old women. Occasional screening could identify 75% CIN. In comparison with the control group, the incidence of earlier first sexual behavior, marriage, and delivery, multiple pregnancy, and frequent abortion was significantly increased in the study group (P < 0.05). We suggest that increased access to uterine cervix cancer screening might be more important than technical improvement.
