Adverse maternal and neonatal outcomes in extremely young mothers (≤ 17 years) versus women aged 20–35 years: a retrospective cohort study in Thailand

Extremely young mothers have increased risks of anemia, preterm birth, low birth weight, and stillbirth. Women aged 20-35 years are more affected by gestational diabetes, placenta previa, postpartum hemorrhage, and cesarean delivery. Therefore, age-specific antenatal care and targeted interventions for adolescent pregnancy are warranted. Trial registration Thai Clinical Trials Registry number. Registration number TCTR20250202002.
