Abstract
Among 34,318 participants in a cervical cancer screening program biopsy-proved cervical neoplasia was found in 166. These women served as cases in a case-control study to investigate the association of selected characteristics with the risk of cervical dysplasia and/or cancer. A random sample of program participants with only negative cytologic tests formed the control group. The following factors showed no association with cervical neoplasia: ethnic affiliation, age at menarche, age at 1st marriage, age at 1st pregnancy, age at birth of 1st child, mean number of children and use of oral contraceptives. Risk of cervical neoplasia was increased in women who were < 40 yr of age; were of poverty or low income status; and were separated, divorced or widowed. A decrease in risk was associated with nulliparity, use of estrogens for relief of menopausal symptoms and use of the diaphragm.
