Retrospective study of pathogens involved in vaginitis among Chinese women

Abstract

BackgroundTo explore the pathogen distribution in Chinese females with vaginitis.MethodsThis retrospective study included Chinese females with vaginitis admitted at the outpatient department of the Gynecology Clinic of the Second Affiliated Hospital of Kunming Medical University between January 2013 and June 2013. Data on the vaginal pathogens and inflammation were analyzed.ResultsThe vaginal secretions from 15,601 gynecologic outpatients were abnormal, including 8547 (54.78%) with vaginal infection and 7054 (45.22%) without. In patients with vaginal infections, a single infection was observed in 69.72% (5959/8547) of them, and mixed infection was observed in 30.28% (2588/8547). The differences in age and inflammation grade between the infection and no-infection groups were statistically significant (all P < 0.001). In addition, multiple types of vaginitis could be diagnosed in patients with mixed infections.ConclusionsAbout half of the Chinese women with abnormal vaginal secretions are positive for pathogens in the study period. Patients’ age and inflammation grade are associated with co-infection. From the public health perspective, this study suggests that the importance of vaginal hygiene should be enforced in Chinese women.
