Maternal and neonatal outcomes of Group B Streptococcus colonization: a retrospective study by Guixiu Jin, Lanhua Liu, Xiaolong Wang, Junling Fei, Zhenling Zhu, Ziyan Jiang, Min Liu

“…Fetal distress (OR, 1.940; 95% CI, 1.355 to 2.778, P < 0.001), neonatal sepsis (OR, 5.063; 95% CI, 2.536–10.109, P < 0.001), low Apgar scores (OR, 2.097; 95% CI, 1.184–3.715, P = 0.011), neonatal pneumonia (OR, 1.638; 95% CI, 1.039 to 2.582, P = 0.034) and neonatal hyperbilirubinemia (OR, 1.438; 95% CI, 1.080 to 1.915, P = 0.013) were significantly related to maternal GBS colonization. When we used the composite adverse neonatal outcomes as the dependent variable and analyzed the influencing factors, the logistic regression analysis revealed that GBS colonization was still significantly related to an elevated risk of adverse neonatal outcomes (OR = 1.752, 95% CI, 1.389–2.208; P < 0.001). …”
