Outcomes and Morbidities in Low-Birth-Weight Neonates: A Retrospective Study From Western India

Abstract

Background: Low birth weight (LBW) increases infant morbidity and mortality and is a major public health concern, especially in resource-constrained settings. The purpose of this retrospective study was to assess the outcomes and morbidities related to LBW neonates referred to a neonatal intensive care unit (NICU) in Western India. Methods: The present study examined the medical records of newborns weighing less than 2 kg at birth who were admitted to the NICU between September 15, 2016, and September 15, 2017. Data on long-term outcomes, clinical manifestations, morbidities, mortality, and demographic variables were gathered and analyzed. Descriptive statistics were used to present continuous variables as mean and standard deviation (SD), while categorical variables were presented as frequencies and percentages. Bivariate and multivariate logistic regression analyses were carried out to find the association between gestational age and major morbidities among LBW babies. Results: Of 4710 births, 327 (6.9%) were LBW. The leading morbidities of LBW babies were respiratory distress syndrome (RDS) 153 (46.8%), neonatal jaundice 92 (28%), and septicemia 81 (25%), contributing to 58 (17.7%) deaths. Lower gestational age was associated with significantly higher adjusted odds of RDS (<28 weeks: reference; 28-32 weeks: adjusted odds ratio (AOR) 0.07, 95% confidence interval (CI) 0.01-0.33; ≥37 weeks: AOR 0.001, 95% CI 0.00005-0.02) and RDS-related mortality (28-32 weeks: AOR 0.26, 95% CI 0.06-1.13; ≥37 weeks: AOR 0.07, 95% CI 0.01-0.43). Among 250 successfully discharged cases, at 12 months, 18 (13.7%) had a weight below the 3rd percentile, and 9 (6.8%) failed the neurodevelopmental screening. Conclusion: LBW infants in this setting experience significant morbidities, mortality, and long-term growth and developmental effects. To alleviate the burden associated with LBW, improved neonatal care facilities, infection control protocols, and focused interventions are essential.
