摘要
Objectives The study assessed racia l differences in vaginal pH among women without bacterial vag inosis.Study design Data from the Vaginal Infections and Prematurity(VIP)Study were analyzed.From 1984to 1989,13,917largely low -income women were enrolled during routine prenatal visits from 23to 26weeks’gestation.Vaginal cultures,Gram stains,and pH levels were colle cted.Comparisons of pH by race were made among women with G ram stain scores<7and without trichomoniasis before and after ad-justment for actual Gram stain score.Results Amongwomen with Gram stain scores<7,there was a modest but statis-tically significant racial differe nce in vaginal pH level.However,after controlling for diff erence in Gram stain score,age,and study site,there was no longer a signifi-cant difference in vaginal pH.Conclusion There is no sig-nificant difference in vaginal pH le vel between black and white women after controlling for di fferences in confounding factors,particularly vaginal flora.
