| Summary: | Introduction: Zinc deficiency is very much prevalent among pregnant women in developing countries. Zinc is required to maintain normal structure and function of multiple enzymes including those that are involved in foetal growth. Zinc deficiency increases risk of baby being born preterm, low birth weight, small for gestational age (SGA). Aims and Objectives: To compare serum zinc levels in small for gestational age babies with respect to appropriate for gestational age (AGA). Material and Methods: Out of total 200 newborn, hundred SGA newborn comprised the study group and hundred AGA newborn comprised the control group. Cord blood sample was collected immediately after birth and zinc levels were determined by atomic absorption spectrophotometry method. Results: The mean (±SD) serum zinc levels of study and control groups were 56.8 ± 40.6 μg/dl and 107.4 ± 72 μg/dl respectively and difference between two groups were found to be statistically significant. The mean serum zinc levels of preterm SGA group and term SGA group were 46.26 ± 22.54 μg/dl and 63.35 ± 47.47μg/dl respectively. Statistically significant difference was found in mean serum zinc levels between the two groups. Conclusion: SGA neonates have significant zinc deficiency as compared to AGA neonates. This zinc deficiency is even more pronounced in SGA newborns that are born preterm. This warrants the future investigation and necessary intervention on zinc supplementation during pregnancy and to preterm and SGA babies for better maternal and child health outcomes.
