摘要

Objective

To describe and compare maternal and perinatal outcomes in adolescent versus adult pregnancies at a tertiary perinatal referral network in South India.

Methods

This hospital-based cross-sectional study included 1,022 adolescent pregnancies (≤ 19 years) compared with 90,911 pregnancies among women aged 20–34 years, at the study site between January 2013 and December 2023. Maternal characteristics, obstetric complications, mode of delivery, and neonatal outcomes were analysed using data extracted from an electronic medical record system.

Results

Adolescent pregnancies accounted for 1.03% (n = 1,022). These were predominantly singleton (98.14% vs.. 97.11%; p = 0.051) and had significantly fewer pre-existing comorbidities such as diabetes (13.7%) and thyroid disorders (13.7%). However, adolescents had higher rates of anaemia (19.86% vs.. 16.38%; p = 0.003), pre-eclampsia (5.68% vs.. 4.13%; p = 0.014), and eclampsia (1.17% vs.. 0.17%; p =  < 0.001). Spontaneous vaginal birth was more common among adolescents (56.09% vs.. 40.73%; p =  < 0.001), while caesarean section rates were lower (31.35% vs.. 48.61%; p < 0.001). Perinatal outcomes, including neonatal survival (~ 99%) and NICU admissions (13.71% vs.. 14.20%; p = 0.654), were comparable between groups. Preterm birth was slightly higher among adolescents (16.14% vs.. 14.05%; p = 0.055), but the difference was not statistically significant.

Conclusion

Adolescent pregnancies accounted for 1.03%. Adolescent pregnancy is associated with higher rates of anaemia and hypertensive disorders of pregnancy, while overall perinatal outcomes were comparable to adult women in a tertiary care setting. Focused adolescent-friendly antenatal care, nutritional optimisation, and vigilant intrapartum monitoring are essential to reduce preventable maternal risks and optimise outcomes.
