  1. Sexual behavior and vaginal colonization by group B streptococus among minority women.

    Article - En anglais


    To test the hypothesis that sexual behaviors predict colonization of the vagina by group B streptococcus among minority women.


    We conducted a prospective, descriptive study of 192 consecutive African-American (37%) and Hispanic women (63%). Each woman underwent a detailed interview concerning sexual behavior.

    Separate specimens were taken from the endocervix, upper vagina, lower vagina, and anorectum and placed in selective broth media for isolation of group B streptococcus.

    Significant behavioral predictors of vaginal group B streptococcus colonization and heavy (3-4+) colonization were identified using stepwise logistic regression.


    The incidence of vaginal colonization was 39% and heavy colonization was 35%. Nineteen percent reported anal intercourse, 46% reported sex at least two times per week, and 21% reported more than one partner in the previous 30 days.

    The significant predictors of vaginal group B streptococcal infection were :

    • African-American ethnicity, adjusted odds ratio (OR) 6.1 (95% confidence interval [CI] 2.5-15.1) ;

    • presence of rectal group B streptococcus, adjusted OR 100.6 (95% CI 26.7-379.3) ;

    • nulliparous, adjusted OR 3.6 (95% CI 1.4-9.5) ;

    • and nonpregnant status, adjusted OR 3.9 (95% CI 1.3-12.2).

    The significant predictors of heavy colonization were : more than one partner in the last 30 days, adjusted OR 2.6 (95% CI 1.2-5.6) ; and African-American ethnicity, adjusted OR 2.3 (95% CI 1.2-4.5). (...)
