Introduction : Adolescent pregnancy is a major global public health concern, associated with increased maternal and neonatal risks such as anemia, eclampsia, preterm birth, and low birth weight. Despite a global decline in adolescent birth rates, India continues to report substantial teenage childbearing. NFHS-5 (2019–21) shows that 6.8% of Indian women aged 15–19 years have begun childbearing, with Tamil Nadu reporting 6%. Teenage pregnancy is strongly linked to early marriage, lower education, and socioeconomic disadvantage. This study aimed to assess the trends, sociodemographic characteristics, and maternal outcomes of teenage pregnancy in Poonamallee HUD, Tamil Nadu, from 2022 to 2025. Methods : A descriptive cross-sectional study was conducted in Poonamallee HUD, Tamil Nadu, using PICME records of 281 teenage pregnancies (2022–2025). Sociodemographic details, pregnancy outcomes, and complications were analyzed.
RESULTS: The prevalence was 1.09%, rising to 2.0% in 2024–2025, coinciding with strengthened registration under PICME 3.0 (January 2024). Most cases were in the 18–19 year group. Normal deliveries accounted for 66%, cesarean sections 32%, and abortions 2%. High-risk conditions were reported in 23.3%, mainly anemia and hypothyroidism.
CONCLUSION: Teenage pregnancies, though relatively low, showed rising trends and significant complications, underscoring the need for targeted adolescent health interventions.
