Abstract

Objective: Rate of vaginal-rectal Streptococcus group B infection in pregnant women at 36-37 weeks and 6 days and related factors at Binh Duong Reproductive Health Care Center. Methods: Cross-sectional study of 222 pregnant women with a gestational age of 36-37 weeks and 6 days, who visited the Binh Duong Reproductive Health Care Center for prenatal examination and were tested for GBS by culture. Results: The rate of GBS infection was 14.9%, (95% CI 0.1-0.2), pregnant women with a history of 1 abortion increased the risk of GBS infection [p < 0.001; PR = 26.338; 95% CI 7.008 – 98.983) and 2 abortions (p = 0.003; PR = 26.530, 95% CI 3.001 – 233.77). Pregnant women with a history of premature birth have an increased risk of GBS infection (p = 0.008; PR 13.823, 95% CI: 1.961- 97.442). In addition, factors such as age, number of births, ethnicity, intercourse during pregnancy, hygiene, and water source do not increase the rate of GBS infection. Conclusion: Early screening will help detect cases of GBS infection so that timely preventive measures can be taken to avoid serious complications for mothers and babies.
