Cytomegalovirus Infection in Women Attending a Sexually Transmitted Disease Clinic

Abstract

To evaluate prospectively the relationship between current and past sexual practices and seroprevalence of cytomegalovirus (CMV) in adult women, 1481 women (1101 white, 301 black, 79 other) attending a sexually transmitted disease clinic underwent a standardized interview and genital examination. CMV seroprevalence was higher in black (78%) than in white (59%) women. In logistic regression models that adjusted for age and years of education, CMV seropositivity in white women was associated with younger sexual debut (P = .001), more lifetime sex partners (P = .025), recent new partner(s) (P = .003), and parity (P = .002), and was inversely associated with use of barrier contraception (P = .006). In black women, after adjustment for demographic characteristics, CMV antibody was associated with greater numbers of recent sex partners (P = .007), new sex partners (P = .04), and with cervical infection with Chlamydia trachomatis (P = .05). This study confirms that sexual activity is an important determinant of CMV infection in both white and black women; however, the relative contributions of sexual and nonsexual transmission of CMV apparently vary and require further investigation.
