大量间接证据表明，改善发展中国家幼儿期的营养状况是一项长期的经济投资。我们调查的直接影响，在幼儿期的营养干预对成人economic productions.Methods我们获得的经济数据，从1424危地马拉人（年龄25-42岁）在2002年和2004年之间。他们占60%的2392名儿童（年龄0-7岁）已登记在营养干预研究在1969年至1977年。在这项初步研究中，两个村庄被随机分配给所有儿童营养补充剂（atole），两个村庄被分配给营养较低的一个（fresco）。我们估计了所有经济活动的年收入、工作时间和平均小时工资。我们使用线性回归模型，调整潜在的混杂因素，以评估经济变量和暴露于atole或壁画在特定年龄之间的关系出生和7 years.Findings暴露于atole之前，但不是之后，3岁与更高的时薪，但仅适用于男性。对于0至2年的原子暴露，每小时增加0.67美元（95% CI 0.16 -1.17），这意味着平均工资增加46%。有一个非显着的趋势，工作时间减少，并为年收入更大的那些暴露于atole从0到2 years.Interpretation改善幼儿营养导致大幅增加的工资率为男性，这表明，投资于幼儿营养可以长期驱动经济增长。
Background Substantial, but indirect, evidence suggests that improving nutrition in early childhood in developing countries is a long-term economic investment. We investigated the direct effect of a nutrition intervention in early childhood on adult economic productivity.Methods We obtained economic data from 1424 Guatemalan individuals (aged 25-42 years) between 2002 and 2004. They accounted for 60% of the 2392 children (aged 0-7 years) who had been enrolled in a nutrition intervention study during 1969-77. In this initial study, two villages were randomly assigned a nutritious supplement (atole) for all children and two villages a less nutritious one (fresco). We estimated annual income, hours worked, and average hourly wages from all economic activities. We used linear regression models, adjusting for potentially confounding factors, to assess the relation between economic variables and exposure to atole or fresco at specific ages between birth and 7 years.Findings Exposure to atole before, but not after, age 3 years was associated with higher hourly wages, but only for men. For exposure to atole from 0 to 2 years, the increase was US$0.67 per hour (95% CI 0 .16-1.17), which meant a 46% increase in average wages. There was a non-significant tendency for hours worked to be reduced and for annual incomes to be greater for those exposed to atole from 0 to 2 years.Interpretation Improving nutrition in early childhood led to substantial increases in wage rates for men, which suggests that investments in early childhood nutrition can be long-term drivers of economic growth.
