The study of 52 cases of cervical intraepithelial neoplasia seen from 1980 to 1984 shows that early sexual activity increases the relative risk 3.35 times if the intercourse takes place before 20 years of age, and 2.5 times if before 15 years. The use of IUD increases the risk 2.77 times. Parity, civil status and gynecologic infections do not increase the risk. Cervical intraepithelial neoplasia is more frequently diagnosed in women with a higher socio-economic status, due to a better health care.
对1980年至1984年间诊治的52例宫颈上皮内瘤变病例的研究表明,过早进行性行为会增加患病风险:若在20岁之前开始性行为,相对风险增加3.35倍;若在15岁之前开始性行为,相对风险增加2.5倍。使用宫内节育器会使风险增加2.77倍。产次、婚姻状况和妇科感染不会增加患病风险。由于医疗保健条件较好,宫颈上皮内瘤变在社会经济地位较高的女性中更易被诊断出来。
