Pediatric Nutrition Determinants, Health Outcomes, and Public Health Implications

Abstract

The importance of pediatric nutrition, however, is its impact on a child growth and development as well as subsequent immune health and long-term outcomes. Adequate consumption of macronutrients and micronutrients in early childhood is critical for healthy physical and cognitive development. Yet there are global disparities, with undernutrition and micronutrient deficiencies continuing to be major public health challenges alongside emerging childhood obesity. The latest epidemiological evidence shows malnutrition is a direct contributory factor in over 45% of all deaths among under-fives worldwide. Rapid dietary transitions and urbanization have simultaneously resulted in increasing prevalence of overweight and metabolic disorders in children. Both extremes of malnutrition undernutrition and overnutrition have long-term consequences such as compromised immunity, poorer education achievement and greater risk for non-communicable diseases in adulthood. This article summarizes current evidence on the determinants of nutritional status in children and adolescents, describes health outcomes associated with nutritional imbalance, and outlines preventive approaches at familial/community/policy levels. As we work to improve sustainable child health outcomes worldwide, reinforcing early-life nutritional interventions continues to be a critical factor.
