We examine the impacts of weather shocks, defined as rainfall or growing degree days, a cumulative measure of temperature, more than a standard deviation from their respective long run mean, on the stature of children between 12 and 47 months of age in Mexico. We find that after a positive rainfall shock children are shorter regardless of their region or altitude. Negative temperature shocks have a negative impact on height in the central and southern parts of the country as well as in higher altitudes. Although on average there are no statistically significant impacts from positive temperature shocks, certain sub-populations - namely boys, children between 12 and 23 months at the time of measurement, and children of less educated mothers - in some of the regions are negatively impacted. The results also suggest that potentially both agricultural income and communicable disease prevalence contribute to the effects.
我们研究了天气冲击（定义为降雨量或生长度日，即温度的累积量，超过其长期平均值一个标准差）对墨西哥 12 至 47 个月大的儿童身高的影响。我们发现，在经历正降雨冲击后，无论其所在地区或海拔如何，儿童的身高都变矮了。负温度冲击对该国中部和南部地区以及高海拔地区的身高有负面影响。尽管平均而言，正温度冲击没有统计学上的显著影响，但某些亚群体——即男孩、测量时处于 12 至 23 个月的儿童以及受教育程度较低的母亲的子女——在某些地区受到了负面影响。结果还表明，农业收入和传染病流行率都可能对这些影响有贡献。
