Evidence on the impact of weather shocks on child nutrition focuses on linear growth retardation (stunting) and thus, associates the effect of a short-term measure (weather events) on a cumulative measure (attained height). Relatively little is known on how weather shocks predict increases in wasting in a population. This study explores whether deviation in rainfall in Ethiopia, a drought prone country, is a sensitive indicator of future increases in wasting. Around 12% of children 0-23 months were wasted, but we found no consistent association between the rainfall shock variables and child weight-for-height Z-scores. The results indicate that monitoring rainfall does not provide a practical early warning to use for scaling up financing and management of preventative measures without additional information to increase precision.
有关天气冲击对儿童营养影响的证据主要集中在生长迟缓（发育不良）上，因此，将短期措施（天气事件）对累积措施（身高）的影响联系起来。关于天气冲击如何预测人群中消瘦的增加，人们知之甚少。本研究探讨了埃塞俄比亚（一个干旱多发国家）的降雨量偏差是否是未来消瘦增加的敏感指标。在 0-23 个月大的儿童中，约有 12%的儿童消瘦，但我们没有发现降雨量冲击变量与儿童身高体重 Z 分数之间存在一致的关联。结果表明，在没有额外信息提高精度的情况下，监测降雨量并不能为扩大融资和管理预防措施提供实用的早期预警。
