Neonatal malnutrition refers to severe undernutrition in newborns, often marked by low birth weight, wasting (weight-for-height z-score < -3), or stunting in the first 28 days. It stems from maternal factors like poor diet during pregnancy, preterm birth, or lactation deficits in protein and energy. This condition disrupts physical growth and cognitive milestones, with long-term effects including higher non-communicable disease risks.

Causes and Risk Factors

Primary causes include inadequate intrauterine nutrition leading to low birth weight or intrauterine growth restriction. Postnatally, insufficient breastfeeding, infections, or socioeconomic barriers exacerbate it, creating a cycle of vulnerability. In low-resource settings, concurrent stunting and wasting prevalence reaches alarming levels among newborns.

Health Impacts

Malnourished neonates face impaired immunity, increasing susceptibility to infections and mortality. It causes irreversible brain damage, metabolic shifts toward diabetes, and developmental delays. Severe cases manifest as marasmus (extreme wasting) or kwashiorkor (edema from protein lack).

Prevention Strategies

Promote exclusive breastfeeding and maternal nutrition to break the malnutrition cycle. Disease prevention via vaccinations and hygiene reduces infection risks. Early screening with mid-upper arm circumference aids timely intervention.
