Alkaline pH could be a cause of preterm labor?

This article from Midwifery Today on pre- and post-term birth gave me new things to think about. Such as this paragraph:

In fact, pH alone—the acid/alkaline level measured by nitrazine or litmus paper—is a marker for prematurity risk. Retrospective and prospective studies show that high vaginal pH (a low acid, or alkaline, state) is predictive of preterm labor and preterm rupture of membranes. Viehweg, et al. state: “Measurements of the vaginal pH value are able to verify an alkalinization of the vagina caused by atypical vaginal flora.…In contrast to normal pregnancies there is a relation between a pathological pH value > 4.5 and consequent preterm birth in pregnancies with preterm labor.”(13) In the Multicenter Bacterial Vaginosis (BV) Trial—a prospective study—21,554 women were screened for vaginal pH and outcome. Women with a vaginal pH of 5.0 or greater had a significantly increased risk of preterm birth and/or low birth weight.(14)

It’s definitely worth a read! Take a look.
