ABSTRACT
At present, the world is off-track to meet the World Health Assembly global nutrition targets for 2025. Reducing the prevalence of stunting in children, low birthweight, and anaemia in women and increasing breastfeeding are among the prioritized global nutrition targets for all countries. Governments and development partners need evidence-based data to understand the true costs and consequences of policy decisions and investments. Yet there is an evidence gap on the health, human capital, and economic costs of inaction on preventing undernutrition for most countries. The Cost of Inaction tool, and expanded Cost of Not Breastfeeding tool, provide country-specific data to help to address the gaps. Every year undernutrition leads to 1.3 million cases of preventable child and maternal deaths. In children, stunting results in the largest economic burden yearly at US$548 billion (0.7% of GNI), followed by US$507 billion for sub-optimal breastfeeding (0.6% global GNI), US$344 billion (0.3% of GNI) for low birthweight and US$161 billion (0.2% of GNI) for anaemia in children. Anaemia in WRA costs US$113 billion (0.1% of GNI) globally in current income losses. Accounting for overlap in stunting, suboptimal breastfeeding, and low birthweight, the analysis estimates that preventable undernutrition cumulatively costs the world at least US$761 billion per year, or $2.1B per day. The variation in the regional and country-level estimates reflect the contextual drivers of undernutrition. In the lead up to the renewed WHA targets and Sustainable Development Goals to 2030, the data generated from these tools are powerful information for advocates, governments, and development partners to inform policy decisions and investments into high-impact low-cost nutrition interventions. The costs of inaction on undernutrition continue to be substantial, and serious coordinated action on the global nutrition targets is needed to yield the significant positive human capital and economic benefits from investing in nutrition.
