Background: Low birth weight (LBW) continues to remain a major public health problem worldwide. There are numerous factors contributing to LBW both maternal and fetal. The mortality of low birth weight can be reduced if the risk factors are detected early and managed by simple techniques. Objective: In this study our main goal is to assess the correlation between maternal factors and infants lower birth weight. Method: This research was conducted as a cross- sectional analysis at a tertiary care medical facility between January 2022 and January 2023. Where a convenience sample of 100 moms aged 11–19 who were hospitalized throughout the research period was chosen. Ultrasound and other diagnostic procedures verified the pregnancy. Results: During the study, the average age of the participants in the study group was 18.02±05 years, and only 19% of the patients visited the antenatal care facility more than four times. Among the study group, 34% of the participants had anemia, followed by 20% with premature rupture of membranes (PROM), 6% with preterm premature rupture of membranes (PPROM), 11% with mild eclampsia, 7% with severe eclampsia, 5% with gestational hypertension, and 6% with gestational diabetes. In terms of delivery methods, 40% had normal spontaneous vaginal delivery (NSVD), 28% had emergency lower segment cesarean section (LSCS), 17% had planned LSCS, and 13% underwent instrumental delivery. Regarding postpartum complications, 5% of the study group experienced postpartum hemorrhage (PPH), 2% had uterine atony, 3% had wound disruption, 1% had perineal tear, and 1% of the cases resulted in maternal death. Adverse neonatal outcomes were also observed, with 15% of the newborns having a body weight of less than 2500 grams, 11% having low APGAR scores, 12% developing neonatal jaundice, 2% experiencing intrauterine growth restriction (IUGR), 2% being stillborn, 1% having congenital anomalies, and 1% suffering from respiratory distress syndrome. ...
