Objective : To study the prevalence of bacterial vaginosis (BV) in pregnant women with preterm labor in
Siriraj hospital.
Materials and Methods : A cross-sectional study of 158 pregnant women with suspected preterm labor was
performed between January and July 2005. The subjects enrolled in the present study were between 28+0 and
36+6 menstrual weeks. BV blue test was performed on the vaginal fluid collected from lower one- third of
vagina.
Results : The prevalence of BV in women in the preterm labor group was 25.8% compared to 14.1% in the
preterm contraction group (p = 0.07).
Conclusion : Compared with preterm contractions a higher prevalence of BV was found in the pregnant
women with preterm labor. Given that a quarter of pregnant women with preterm labor tested positive for BV,
it might be appropriate to perform this test in the triage setting.
