The infection may be transmitted vertically and may result in serious neonatal consequences. In the period from November 2003 to May 2004, a cross-sectional study was carried out among 316 parturients at the Jundiaí Teaching Hospital to establish the prevalence...

Maternal Obesity and Rectovaginal Group B Streptococcus Colonization at Term

OBJECTIVE To test the hypothesis that maternal obesity is an independent risk factor for rectovaginal group B streptococcus (GBS) colonization at term. STUDY DESIGN Retrospective cohort study of consecutive women with singleton term pregnancies admitted in labor at Barnes-Jewish Hospital (2004-2008). Maternal BMI≥30 Kg/m2 (obese) or <30 Kg/m2 (nonobese) defined the two comparison groups. The ...
