Interleukin-1 Receptor Antagonist Gene Polymorphism and Adverse Pregnancy Outcome in Turkish Women

Pregnant women between 18-35 years of age with single gestation and with ≥20 on-crowded teeth excluding third molars were included in this study. Subjects were divided into normal birth (NB) and PLBW groups on the basis of their pregnancy outcome. Women who delivered an infant with a birth weight of more than 2500 g after 37 weeks of gestation were placed in the NB group. Women who delivered infants whose birth weight was below 2500 g or before 37 weeks of gestation were placed in the PLBW group. Current/past tobacco user, alcohol abuse, history of high-risk gestation, hypertension, gestational diabetes, any systemic disease and placenta previa were the exclusion criteria for this study. Maternal, obstetric, and demographic factors such as maternal age, maternal education, regular prenatal care, genitourinary tract infections during pregnancy, total number of births, previous PLBW, and antibiotic use during the pregnancy period were also recorded.
