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 数据来检验假设，更好的营养在幼儿期 通过其对积累的有益影响， 人力资本。被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， 家庭环境、生长、认知发展、饮食和 发病率，评估了改善营养的影响， 1969年至1977年进行的儿童对照补充试验， 促进经济增长和发展。1988-89年的一项后续研究评估了人力资本 在11至26岁时形成和生产力。对这些数据的分析使我们 得出结论，幼儿期更好的营养改善了人力资本; 这一结论必然是暂时的，因为只有不到一半的人 达到成年。此外，我们无法测试 儿童早期营养和成人生产力，因为 样本已经结婚或在一个有稳定工作的职业中定居 和/或独立于父母家庭。因此，我们建议 在2002年收集新一轮的数据，届时将是25至40岁的人群。 年龄队列成员将被跟踪和研究，他们是否仍然生活在他们的 出生地或迁移。配偶也将被研究。 我们的研究将是第一个将前瞻性收集的数据与早期 儿童营养与经济数据（包括身体健康和心理健康数据） 资本、家庭组成、移徙和职业以及农业和 非农业经济生产力）在成熟的成年人，因此，第一个 能够有效地检验这些关系。我们的研究团队包括 在人类学、经济学、营养学、流行病学、 生物统计学和医学，提供广泛的多学科经验。三 每个机构都有强大和互补的研究传统， 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。三 参与机构有成功的合作历史 在复杂的实地研究和其他研究中。
