trachomatlt in female college students. Am J Epidemiol 1985;121:107-15. Chlamydla trachomatia was isolated from genital specimens from 21 (4.9%) of 431 female college students. Antibody to C. trachomatlt was found in the genital secretions of 52 (11.9%) of 437 women. Multiple logistic regression analysis showed race, number of sexual partners, and use of barrier methods of contra-ception to be predictive of infection with C. trachomatlt.

White participants were infected less often (12 of 388 (3.1%)) than Mack participants (9 of 43 (20.9%)) (p < 0.001) and were less likely to have local chlamydial antibody. None of the sexually inexperienced women were infected or had local antibody. Among the sexually experienced women, chlamydial infection and local chlamydial antibody increased with increasing number of sexual partners only for women who were not using barrier methods of contraception. Sexually experienced women who used barrier methods o
