Comparative Study
Barrier methods of contraception and cervical intraepithelial neoplasia.
This North Carolina-based case-control study examined risk factors for cervical intraepithelial neoplasia (CIN). Cases were 103 women with biopsy-confirmed CIN II or III who were recruited from a referral dysplasia clinic. Controls were 258 family practice patients with normal cervical cytology. ⋯ The risk of CIN II/III decreased further with increasing years of barrier method use. Recency, latency, and age at first barrier method use were all associated with a reduced risk of CIN. Men and women should carefully consider the range of benefits of barrier method use as a means to reduce their risk of unwanted pregnancies, sexually transmitted diseases, and cervical neoplasia.
