Climate-Induced Nutritional Stress And Immunological Resilience In Infants And Toddlers

Abstract

Climate change is increasingly recognized as a significant determinant of child health, with its effects particularly severe in infants and toddlers who are biologically vulnerable to both nutritional deficiencies and immune dysregulation. This study presents a simulation-based investigation into how climate-induced variables—such as rising temperature, food scarcity, and humidity fluctuations—interact with macronutrient intake levels to influence immunological resilience in early childhood. Using multi-dimensional simulations, we modeled the degradation of immune markers including IgA, IL-6, and CRP under varying bioclimatic stress conditions and analyzed recovery trajectories post-intervention. The findings indicate a strong non-linear relationship between climate stress indices and immune deterioration, particularly in children under 18 months. Simulated interventions involving age-optimized supplementation protocols show partial reconstitution of immune profiles, though regional disparities persist due to ecological and metabolic heterogeneity. These results highlight the urgent need for climate-adaptive nutritional programs and biomarker-based tracking systems for early risk detection in vulnerable populations.
