Abstract: Objective To investigate the relationship between Group B Streptococcus (GBS) infection in pregnant women and adverse pregnancy events (APEs), as well as serum inflammatory factors (IFs) and coagulation parameters.Methods A retrospective analysis was conducted on 2,200 late-pregnancy women who delivered at Maternal and Child Health Hospital from March 2020 to January 2023. Data on GBS infection, serotyping, immunofluorescence, coagulation parameters, and APEs were collected. APE incidence was compared between groups, and logistic regression was performed to analyze inflammatory factors and coagulation parameters in GBS-positive women with and without APEs.Results Among the participants, 593 (26.95%) were GBS-positive, and 1,607 (73.05%) were GBS-negative. The GBS-positive group had significantly higher rates of preterm birth, intrauterine infection, premature rupture of membranes, placental abruption, postpartum hemorrhage, and meconium-stained amniotic fluid compared to the GBS-negative group (p < 0.05). Logistic regression identified white blood cell count, high-sensitivity C-reactive protein, tumor necrosis factor-α, interleukin-6 (IL-6), interleukin-1β, procalcitonin, and fibrinogen as independent risk factors for APEs (p < 0.05).Conclusion GBS infection increases the risk of adverse pregnancy events and is closely associated with alterations in inflammatory and coagulation markers.
