Lateral placentation may compromise placental perfusion, and we aimed to assess whether it impacts pregnancy outcomes. This single-center retrospective study included 1203 singleton pregnancies, categorized into two groups according to placental location. Women with lateral placenta had significantly higher risk of preterm birth <37 weeks (aOR 2.99) and <34 weeks (aOR 3.92), and gestational diabetes (aOR 2.72), compared to women with central placenta. Mean birth weight and small for gestational age (SGA) rates were similar between groups. Our findings suggest that lateral placenta may be associated with increased risk for preterm birth but not for SGA.
•Lateral placentation is associated with an increased risk of preterm birth both before 37 and before 34 weeks of gestation.•Lateral placentation is associated with an increased risk of gestational diabetes.•Assessing the placenta location in early pregnancy might be helpful in risk assessment for preterm birth.
