DESCRIPTION: Our study will integrate existing and new prospectively-collected data to test the hypothesis that better nutrition during early childhood enhances adult productivity through its beneficial effects on the accumulation of human capital. The population to be studied was born in four villages in Guatemala. Early childhood data come from a well-known longitudinal study, rich in data about the home environment, growth, cognitive development, diet and morbidity, which assessed the impact of improved nutrition, achieved through a controlled supplementation trial conducted between 1969 and 1977, on child growth and development. A follow-up study in 1988-89 assessed human capital formation and productivity at age 11 to 26 years. Analyses of these data led us to conclude that better nutrition in early childhood improved human capital; this conclusion was necessarily tentative as less than half of the cohort had reached adulthood. Moreover, we were unable to test relationships between nutrition in early childhood and adult productivity, because only a fraction of the sample had married or settled in an occupation with steady employment and/or were independent of the parental household. We, therefore, propose to collect a new round of data in 2002, when the cohort will be 25 to 40 years of age. Cohort members will be traced and studied whether they still live in their birth village or have migrated. Spouses will also be studied. Our study will be the first to link prospectively collected data on early childhood nutrition to economic data (including on physical health and mental capital, family formation, migration and occupation, and agricultural and non-agricultural economic productivity) in mature adults, and, thus, the first to be capable of validly testing these relationships. Our study team includes accomplished researchers in anthropology, economics, nutrition, epidemiology, biostatistics and medicine, providing broad multidisciplinary experience. Three institutions, each with strong and complementary research traditions and resources participate as equal partners: the Rollins School of Public Health of Emory University, the International Food Policy Research Institute and the Institute of Nutrition of Central America and Panama (INCAP). The three participating institutions have a successful history of previous collaboration in complex field studies and other research.

描述：我们的研究将整合现有的和新的前瞻性收集的 数据检验以下假设：幼儿期营养状况更好 通过其对积累的有益影响提高成人生产力 人力资本。所研究的人口出生在四个村庄 危地马拉。幼儿期数据来自一项著名的纵向研究，丰富 有关家庭环境、成长、认知发展、饮食和 发病率，评估了改善营养的影响，通过以下方法实现 1969 年至 1977 年间针对儿童进行的对照补充试验 成长和发展。 1988-89 年的一项后续研究评估了人力资本 11至26岁时的形成和生产力。对这些数据的分析引导我们 得出结论：幼儿期更好的营养可以改善人力资本； 这个结论必然是暂时的，因为只有不到一半的人 已成年。此外，我们无法测试之间的关系 幼儿期营养和成人生产力，因为只有一小部分 样本已结婚或定居于有稳定工作的职业 和/或独立于父母家庭。因此，我们建议 2002 年收集新一轮数据，届时该群体的年龄将达到 25 至 40 岁 年龄。队列成员将被追踪和研究他们是否仍然住在自己的房子里 出生村庄或已经迁移。配偶也将被研究。 我们的研究将是第一个将前瞻性收集的早期数据联系起来的研究 儿童营养到经济数据（包括身体健康和心理数据） 资本、家庭组成、移民和职业以及农业和 成熟成年人的非农业经济生产力），因此，第一个 能够有效地测试这些关系。我们的研究团队包括 人类学、经济学、营养学、流行病学等领域卓有成就的研究人员， 生物统计学和医学，提供广泛的多学科经验。三 各机构均具有强大且互补的研究传统 资源作为平等伙伴参与：罗林斯公共卫生学院 埃默里大学、国际粮食政策研究所和 中美洲和巴拿马营养研究所 (INCAP)。三个 参与机构之前有过成功的合作历史 复杂的实地研究和其他研究。
