title: [Frequency of intraepithelial neoplasia of the cervix and risk factors in women in Mexico City].
abstract: Cervical intraepithelial neoplasies (CIN), are very frequent in women with active sexual life who present risk factors. In this paper 220 exfoliative cytology reports from the National Cancer Register of the Direction of Epidemiology, Health Secretory, taken to women from eight Political Delegations in Mexico City, were revised. 134 cases presented CIN. 70.2% were grade III, corresponded to the age group between 26 and 35 years old; more than three pregnancies (47.76%) and more than three births (46.80%). Viral genital infections were related with CIN grades II and III. There are another risk factors that have been poorly analyzed in the national existent literature, therefore, it is necessary to effect further studies to determine the development of CIN in women with active sexual life.
