Case-control study on risk factors of cervical cancer

  Objective   To investigate the risk factors of cervical cancer in high incidence areas.

  Methods   A hospital based case-control study was conducted.129 cases with cervical cancer by pathological diagnoses and 143 patients with non-neoplasm as controls were interviewed using a questionnaire, including baseline information, menstrual, marital and pregnancy histories, sexual behavior, contraception history and personal health habits, etc.

  Results   Based on monovariate analysis results, multivariate non-conditional logistic analysis was used.Personal income, age at first intercourse, bath service, parity, menopause and history of gynecologic disease were associated with cervical cancer.Meanwhile, the marriage age, first intercourse age, pregnancy and birth age, gravidity and parity expressed the relationship of dosage-response with cervical cancer.

  Conclusion   The relative risk of cervical cancer enhanced with decreasing age at first intercourse, number of taking bath and personal income, and with increasing number of gravidity and parity.No good health-habit was related to cervical cancer, which should be taken more attention to.The risk on occurrence of cervical cancer reduced in women with post-menopause.
