• Note (General): type:Thesis; OBJECTIVE: To determine the relationship between preterm labor and delivery, and the pH and buffer capacity of vaginal secretions. METHODS: Between January 1, 2009 and March 31, 2012, two cohorts of patients at 22-36weeks of pregnancy were enrolled in a prospective cohort study at Nara Medical University Hospital, Japan. Patients experiencing preterm contractions and a control group of patients experiencing normal pregnancies were included. The pH and buffer capacity of vaginal secretions were measured and compared. RESULTS: Of the 237 patients enrolled, 48 (20.3%) were experiencing symptoms of preterm labor and 189 (79.7%) were included in the control group. The pH was higher (P<0.001) and the buffer capacity was lower (P=0.0135) in the vaginal secretions of the patients experiencing preterm contractions compared with the control group. There was no difference in the pH and buffer capacity of the vaginal secretions of symptomatic patients who would experience preterm delivery and those who would not. Receiver operating characteristic curve analyses demonstrated that vaginal-secretion pH and buffer capacity could differentiate between patients experiencing preterm contractions and those not, but could not differentiate between patients who would experience preterm delivery and those who would not. CONCLUSION: Vaginal-secretion pH and buffer capacity could be useful in diagnosing preterm labor; further studies are needed to determine potential practical diagnostic criteria.; 博士（医学）・乙第1383号・平成28年9月28日; Copyright © 2016 International Federation of Gynecology and Obstetrics.
