title: [Cervical-uterine-cancer associated factors in Nayarit state, Mexico].
abstract: OBJECTIVE
  To establish the association between high-grade intraepithelial lesions and cervical-uterine-cancer, and the infection by human papillomavirus, genetic antecedents, socioeconomics, sexual behavior and gynecology and obstetrics factors in women of the State of Nayarit, Mexico.
  
  
  METHODS
  With a case-control design were studied 66 cases of high-grade intraepithelial lesions and cervical-uterine-cancer, and 132 controls. The information upon the risk factors was obtained by the application of a structured questionnaire. Polymerase Chain Reaction executed the virus identification. In the statistical analysis the association was obtained by odds ratio. The statistical significance was evaluated by the chi-square-Fisher and Student t tests, and multivariate logistic regression was used to explain the factors' influence.
  
  
  RESULTS
  In women with high-risk squamous intraepithelial lesions and cervical-uterine-cancer, the most frequently high-risk human papillomavirus found were: 18, 35, 58, 16, 31, 33 and 51.
  
  
  CONCLUSIONS
  Familial data of cervical-uterine-cancer, socioeconomic level, number of sexual partners, data of sexual transmitted diseases, and infection due to human papillomavirus 18 and 35 are the factors related to high-risk squamous intraepithelial lesions and cervical-uterine-cancer.
