Maternal and Child Nutrition in the First 1,000 Days: A Narrative Review of Stunting Prevention Strategies

Abstract

Background: The first 1,000 days, spanning conception to a child's second birthday, represent a critical window during which nutritional deficits can cause irreversible impairment of linear growth, cognitive development, and long-term human capital. Stunting, the principal indicator of chronic undernutrition during this period, continues to affect more than 148 million children under five worldwide, with Indonesia recording a national prevalence of 21.6% in 2022, well above the World Health Organization's public health threshold. This narrative review synthesizes current evidence on the causes, consequences, and evidence-based interventions for stunting prevention within the first 1,000 days, with particular attention to the Indonesian context.

Methods: A non-systematic literature search was conducted in PubMed, the Cochrane Library, and Google Scholar for Lancet series papers, systematic reviews, meta-analyses of randomized controlled trials, and Indonesia-specific epidemiological studies published primarily within the last fifteen years.

Results: Evidence consistently supports a defined package of nutrition-specific interventions, including maternal balanced energy-protein and multiple micronutrient supplementation, promotion of early and exclusive breastfeeding, appropriate complementary feeding, and vitamin A and zinc supplementation, alongside nutrition-sensitive approaches such as water, sanitation, and hygiene improvement, kangaroo mother care, and social protection. In Indonesia, determinants of stunting include nonexclusive breastfeeding, low maternal height and education, household poverty, and inadequate sanitation, compounded by substantial regional disparities.

Conclusion: Sustained reduction of stunting requires the integrated, well-resourced delivery of proven nutrition-specific and nutrition-sensitive interventions throughout the first 1,000 days, accompanied by continued investment in maternal education, sanitation infrastructure, and social protection, particularly in high-burden regions of Indonesia.
