  1. Epidemiologic determinants of vaginal pH.

    Article - En anglais

    OBJECTIVES 

    This study was undertaken to evaluate the relationship between vaginal pH and factors related to cervical cancer.

    STUDY DESIGN 

    In a population-based sample of 9161 women from Guanacaste Province in Costa Rica women were categorized into 2 groups, those with vaginal pH in the reference range (4.0-4.5) and those with elevated vaginal pH (5.0-5.5).

    Odds ratios were used to estimate the relationship between elevated pH and its potential determinants.

    RESULTS 

    Aging was strongly associated with increasing vaginal pH, starting at around 45 years of age and continuing into old age.

    Menopause was responsible for an additional 1.7-fold increase in the odds of having an elevated pH (odds ratio 1.7,95% confidence interval 1.4-2.0).

    Human papillomavirus infection and cervical intraepithelial neoplasia were not associated with changes in pH.

    CONCLUSIONS 

    Our data indicate that vaginal pH is strongly related to age and to menopausal status and thus could be a marker of age-related hormonal changes.

    Elevated pH does not appear to be associated with risk of high-grade intraepithelial neoplasia among women infected with human papillomavirus.
