Introduction: Adolescent pregnancy is a condition with significant risk that necessitates expert prenatal care to get positive results. Teenage pregnancies continue to be a significant cause of fatality for both mothers and children. The primary cause of death for females between the ages of 14 and 19 worldwide is complications associated with pregnancy and childbirth. This study compares the delivery outcomes and demographics of teenage moms (ages 14-19) who are pregnant with older mothers who are 20-29 years old to ascertain the rate of teenage hospital deliveries atSNMMCH in Dhanbad, Jharkhand, India. We also pinpoint the variables linked to worse pregnancy outcomes. Methodology: This cross-sectional study had both prospective and retrospective phases. Severe preeclampsia is defined as the following: the mothers must have eclampsia, a persistent platelet count <100,000/mm3, serum transaminases greater than twice normal, proteinuria >5 g per 24 hours or ≥+2 using the dipstick test, and systolic and diastolic blood pressure measurements taken at least twice, six hours apart. Results: Thirteen percent of births were to teenagers. Unfavorable fetal outcomes associated with teenage deliveries included low birth weight (less than 2,500 g) (OR, 2.79; 95% CI, 1.28-6.09), low 5-min Apgar score (<7; OR: 1.66; 95% CI, 0.91-3.0), and preterm newborns (less than 37 weeks) (OR: 1.85; 95% CI, 1.01-3.41). Perineal tears were the primary significant maternal outcome linked to teenage pregnancies (OR, 1.6; 95% CI, 0.95-2.7). Premature rupture of the membranes, cesarean section, episiotomy, and preeclampsia/eclampsia have not been significantly linked to teenage pregnancies. Adolescent fetal outcomes were found to be negatively impacted by maternal characteristics such as age and gravidity. In contrast, adverse maternal effects were directly caused by maternal factors such as marital status, age, unemployment, and gravidity. Conclusion: Teenage pregnancies atSNMMCH are not uncommon. Adolescent pregnancies carry a higher chance of unfavorable outcomes for both the mother and the fetus than adult pregnancies.
