This article summarizes research based on the INCAP Longitudinal Study that demonstrates the positive effects of the atole intervention on prime-age adult cognitive skills and productivities. The findings are interpreted in the context of a life-cycle stages model in which various factors and investments at each stage of life influence outcomes not only in that stage but in subsequent ones. The results point to the likely importance of improvements in adult cognitive skills due to better early-life nutrition on adult male labor market outcomes as well as on women’s “home productivity” in terms of anthropometrics for the next generation. Possible mechanisms are also explored, including the impacts of early-life exposure to atole on children’s height when starting school, on grades of schooling attainment, and on the extent of experience with higher-skilled jobs, as well as the impacts of improved cognitive skills on wages. Not only are investments in early-life nutrition important for immediate welfare but also they have significant productivity payoffs in adulthood.

营养、成人认知技能和生产力：INCAP 纵向研究的结果和影响

本文总结了基于 INCAP 纵向研究的研究，该研究证明了 atole 干预对壮年成人认知技能和生产力的积极影响。研究结果在生命周期阶段模型的背景下进行解释，在该模型中，生命每个阶段的各种因素和投资不仅会影响该阶段的结果，还会影响后续阶段的结果。结果表明，由于更好的早期营养对成年男性劳动力市场结果以及女性在下一代人体测量学方面的“家庭生产力”，成人认知技能的改善可能很重要。还探讨了可能的机制，包括早年接触 atole 对儿童入学时的身高、学业成绩、以及从事高技能工作的经验程度，以及认知技能提高对工资的影响。对生命早期营养的投资不仅对眼前的福利很重要，而且在成年后也会产生显着的生产力回报。
