论文摘要
我们检查了危地马拉和菲律宾6到24个月大的儿童蛋白质和能量摄入对身高和体重生长的影响。使用工具变量来控制内生性并估算多个规格，我们发现蛋白质摄入量在6-24个月的时间内在身高和体重增长中起着重要而积极的作用。但是，来自其他大量营养素的能量与这两种人体测量指标没有牢固的关系。我们的估计表明，在大量儿童营养不良的情况下，最初24个月蛋白质富含蛋白质的食物摄入量的增加可能会产生重要的生长效应，以前的研究表明，这与整个生命周期中的一系列结果显着相关。
We examine effects of protein and energy intakes on height and weight growth for children between 6 and 24 months old in Guatemala and the Philippines. Using instrumental variables to control for endogeneity and estimating multiple specifications, we find that protein intake plays an important and positive role in height and weight growth in the 6-24 month period. Energy from other macronutrients, however, does not have a robust relation with these two anthropometric measures. Our estimates indicate that in contexts with substantial child undernutrition, increases in protein-rich food intake in the first 24 months can have important growth effects, which previous studies indicate are related significantly to a range of outcomes over the life cycle.
