Aerobic vaginitis in late pregnancy and outcomes of pregnancy
The purpose of this study was to investigate the risk factors and pregnancy outcomes for aerobic vaginitis (AV) in late pregnancy. A total of 624 pregnant women who were treated in the perinatal unit at Tianjin Medical University General Hospital and 365 nonpregnant women who were evaluated at a health management center from January 2015 to June 2016 were recruited for this case-control study. A questionnaire covering personal hygiene habits and sociodemographic factors was administered to pregnant women to analyze risk factors for AV. Bacterial vaginosis, AV, vulvovaginal candidiasis, and Trichomonas vaginitis were scored according to standardized definitions. Pregnancy outcomes were followed up and recorded. The chi-square test and univariate and multivariate logistic regression analyses were used for statistical evaluation. The prevalence of vaginal infection in pregnant and nonpregnant women were 27.9% and 15.3%, respectively (P < 0.05). AV was identified more frequently in pregnant women than in nonpregnant women (4.2% vs. 1.4%; P < 0.05). A history of vaginal infection within 1 year (odds ratio [OR] = 3.219, 95% confidence interval [CI] 1.103–9.346) and external hemorrhoids (OR = 11.233, 95% CI 4.647–27.155) were independent risk factors for AV during pregnancy. A higher incidence of premature rupture of membranes (PROM) was significantly associated with AV (P < 0.05). AV is common in late pregnancy. Clinicians should pay more attention to vaginal microbiota evaluations during pregnancy.
