BACKGROUND: The aim of this study was to analyze the differences in vaginal microecological factors and genital tract infections among pregnant women of different ages.
MATERIAL AND METHODS: This study included 751 pregnant women from West China Second University Hospital, Sichuan University, China, from January 2015 to April 2017. After gram staining, the vaginal microecological factors of these cases were observed, including vaginal cleanliness, lactobacillus number, bacterial density, flora diversity, dominant bacteria, pH, clue cells, Candida species, and Trichomonas vaginalis.
RESULTS: There was no significant difference in bacterial density, flora diversity, vaginal cleanliness, or lactobacillus number among pregnant women of different age groups. Of the 32.62% of pregnant women who had genital tract infections, the incidence of bacterial vaginosis, Candida albicans infection, non-albicans Candida infection, and T. vaginalis infection were 20.91%, 14.91%, 4.26%, and 1.73%, respectively. The amalgamative incidence of bacterial vaginosis was 9.19%. The incidence of non-albicans Candida infection in the optimum reproductive age group was higher than in the older age group (P=0.0433). The incidence of T. vaginalis infection in the younger age group was higher than in the optimum reproductive age group and higher than in the older age group (P=0.0010 and P=0.0041).
CONCLUSIONS: The microecological status of pregnant women was basically the same as that of normal women. The most frequent genital tract infection was bacterial vaginosis. While bacterial vaginosis is amalgamative with vulvovaginal candidiasis and T. vaginalis infection, there was no significant difference in vaginal microecological observations among pregnant women in different age groups except that the non-albicans Candida infection incidence in the optimum reproductive age group and the T. vaginalis infection incidence in the younger age group was higher than in the other groups.
