发育迟缓影响着全球1.6亿学龄前儿童，并造成终生不良后果。虽然营养科学领域的研究表明，儿童早期发育迟缓与动物性食品（asf）摄入量低有关，但这一话题很少受到经济学家的关注。我们试图通过对来自49个国家的130,432名6-23个月的儿童的分析来纠正这一遗漏。我们记录了不同地区儿童ASF消费的独特模式。我们发现了发育迟缓与非瘟病毒消费指标以及乳制品、肉/鱼和蛋类消费指标之间存在强烈关联的证据，并且有证据表明，食用多种非瘟病毒比食用单一非瘟病毒更有利。我们探讨了为什么非洲猪瘟消费量低，但各国之间差异如此之大。在低收入国家，不可交易的asf（鲜奶、鸡蛋）是一种非常昂贵的热量来源，这些食物的热量价格与儿童的消费模式密切相关。其他需求侧因素也很重要，但价格的强大影响意味着农业政策在生产、营销和贸易方面发挥着重要作用，以提高较贫穷国家非粮食作物的可及性和可负担性。
Stunting affects 160 million pre-school children globally with adverse life-long consequences. While work within nutritional science suggests that stunting in early childhood is associated with low intakes of animal-sourced foods (ASFs), this topic has received little attention from economists. We attempt to redress this omission through an analysis of 130,432 children aged 6–23 months from 49 countries. We document distinctive patterns of ASF consumption among children in different regions. We find evidence of strong associations between stunting and a generic ASF consumption indicator, as well as dairy, meat/fish, and egg consumption indicators, and evidence that consuming multiple ASFs is more advantageous than any single ASF. We explore why ASF consumption is low but also so variable across countries. Non-tradable ASFs (fresh milk, eggs) are a very expensive source of calories in low-income countries and caloric prices of these foods are strongly associated with children’s consumption patterns. Other demand-side factors are also important, but the strong influence of prices implies an important role for agricultural policies—in production, marketing and trade—to improve the accessibility and affordability of ASFs in poorer countries.
