Comparison of Physical Growth Between Low Birth Weight and Normal Birth Weight Babies Aged Between 24-36 Months Born in a Selected Hospital of Dhaka, Bangladesh

Abstract

This study investigates the physical growth disparities between Low Birth Weight (LBW) and Normal Birth Weight (NBW) babies aged 24-36 months in a selected hospital in Dhaka. The research sample comprised 200 babies, evenly split between LBW (birth weight < 2500 grams) and NBW (birth weight ≥ 2500 grams) groups. Physical growth parameters including weight, height and head circumference were measured and analyzed using descriptive statistics and comparative tests. The findings reveal significant differences in all measured parameters between LBW and NBW infants. LBW babies exhibited lower mean values in weight (11.5 kg vs. 13.0 kg), height (85.0 cm vs. 89.0 cm) and head circumference (48.0 cm vs. 49.0 cm) compared to NBW babies. Statistical analyses confirmed these differences to be significant (p < 0.05), highlighting the persistent impact of birth weight on early childhood growth. These results underscore the importance of targeted healthcare interventions for LBW infants to mitigate growth disparities and promote optimal development. Early childhood growth failure in LBW infants has long-term implications for health and developmental outcomes, necessitating comprehensive healthcare strategies that include nutritional support, growth monitoring and developmental assessments. By addressing these challenges, healthcare providers and policymakers can improve the long-term health and well-being of LBW infants, ensuring they have the opportunity to achieve their full developmental potential. This study contributes valuable insights to the field of maternal and child health in Bangladesh, guiding future research and healthcare initiatives aimed at supporting LBW infants and reducing health disparities.
