Background:
Perinatal nutrition is essential for fetal growth and neonatal health and for the maturation of the immune system. Deficiencies of nutrients in pregnancy and early infancy may affect physical development and may increase susceptibility to infections.
Objective:
To evaluate the effect of perinatal nutritional supplementation on growth and immune system development during the first year of life.
Methodology:
This was a prospective study of 200 pregnant women who were given balanced nutritional supplementation of protein, iron, folic acid, vitamins and essential minerals from 2nd trimester till 6 months post-partum. We measured infant growth parameters and immune markers at birth and at 12 months of age.
Findings: -
Infants born of supplemented mothers showed significantly improved growth indices versus controls. Mean birth weight was increased by 320 g (3.34 ± 0.41 kg vs 3.02 ± 0.39 kg) and length-for-age z-scores improved by 12.5% at 12 months. In addition, serum immunoglobulin A (IgA) concentrations were 18% higher and the incidence of respiratory infections was 24% lower during the first year of life. Infants who were supplemented also showed improved vaccine responses.
Conclusion:
Perinatal nutritional supplementation positively influences infant growth and supports immune system development. Integrating comprehensive nutritional interventions during pregnancy and early postpartum periods may contribute to improved child health outcomes and reduced infection-related morbidity.
