Cervical intraepithelial neoplasia in female prisoners in British Columbia.

Abstract

The annual incidence rates of cervical intraepithelial neoplasia (CIN), grades I to III, from 1975 to 1983 among 2440 prisoners in British Columbia for whom a history of screening by means of the Papanicolaou test was available were two to three times higher than the expected rates in the general female population of British Columbia. The rates among the prisoners from 1970 to 1984, although small, increased with a trend similar to that in the general population. Despite increases in the general population we conclude that prisoners are still at high risk for CIN.
