This study identifies the prevalence of vaginal flora alterations in low-risk pregnant women and their association with reported symptoms and gynecological exams. This quantitative, descriptive, cross-sectional study was conducted in public primary care service units in Botucatu, SP, Brazil from 2006 to 2008 with 289 pregnant women from a stratified sample obtained by sampling by care unit. Tests of vaginal content were performed using Gram’s method and testing for Trichomonas vaginalis using Diamond’s medium. The prevalence of altered vaginal flora was 49.5%, of which bacterial vaginosis (20.7%), vaginal candidiasis (11.8%) and intermediate flora (11.1%) were the most frequent, not considering associations. Results revealed a high prevalence of vaginal flora alterations with little relation to symptoms, but in agreement with findings from the gynecological exams. Considering undesirable maternal and perinatal outcomes and feasible laboratory practices, the establishment of a routine for diagnosing vaginal flora alterations in low-risk pregnant women is suggested.
