BACKGROUND: Vaginal infections are a frequent cause for consultation, but their prevalence and etiology vary in different populations.
OBJECTIVES: To determine the prevalence and etiologies of vaginal infection in women attending a family health center in the Metropolitan Region of Chile.
METHODS: The microbiological diagnosis was made by wet mount and Gram stain. Diagnosis of trichomoniasis was performed by wet mount, culture and polymerase chain reaction.
RESULTS: 101 women aged 15-54, not selected by signs or symptoms of vaginal infection, 46 of them pregnant were included. In 47 women (46.5%), vaginal infections were diagnosed. An association was observed between age and frequency of vaginal infection. The proportion of infections among pregnant and non-pregnant women was similar. The most frequent infections were bacterial vaginosis (16.8%), vulvovaginal candidiasis (11.9%) and co-infections (6.9%). We found 5.9% of intermediate microbiota cases, 3% of trichomoniasis and 2% of aerobic vaginitis. Symptoms of vaginal infection had poor agreement with microbiological findings. Otherwise physical signs had good agreement with the presence of infection, but low to moderate concordance with a specific etiology.
CONCLUSIONS: We found a high prevalence of vaginal infections in the study population. It is necessary to improve the definitions and criteria of microbiological diagnosis of co-infections and intermediate microbiota, for them to be diagnosed in the clinical practice. More descriptive questionnaires are recommended to enhance the usefulness of clinical examination.
