PROJECT SUMMARY This project will study how exposure to armed conflict affects the nutritional status of women and children in sub-Saharan Africa. I link nutritional data on 725,619 women and 484,546 children from 35 sub-Saharan African countries to conflict records during physiologically relevant critical periods. I then measure the effects of conflict exposures on the weight-for-height of children ages 0-23 months, the height-for-age of children ages 24-59 months, and the body mass index of women ages 15-49 years, while controlling for relevant demographic characteristics and spatio-temporal confounders. I extend overall estimates of conflict effects by testing for heterogeneity across social groups and between countries, evaluating whether concurrent climate shocks amplify the effects of conflict, and empirically examining the role of agricultural, economic, health, and familial mechanisms. I then examine potential selection effects by measuring conflict and climate effects on fertility and child mortality. The analyses also include a series of supplementary analyses and robustness checks, such as analyses of adult male body mass index, tests for non-linearities in conflict and climate effects, and assessments of data quality. This study provides new cross-national evidence about the nutritional effects of conflict in Africa, fills evidence gaps about acute malnutrition in conflict settings, and integrates the emerging literatures on the health effects of conflict and climate. The results will inform debates about nutritional security in a period of widespread conflict and growing climatic variability.

项目概要 该项目将研究武装冲突如何影响妇女和儿童的营养状况 撒哈拉以南非洲。我链接了来自 35 个撒哈拉以南地区 725,619 名妇女和 484,546 名儿童的营养数据 非洲国家在生理相关的关键时期有冲突记录。然后我衡量的效果 0-23个月儿童身高别体重、各年龄段儿童年龄别身高的冲突暴露 24-59个月，以及15-49岁女性的体重指数，同时控制了相关因素 人口特征和时空混杂因素。我将冲突影响的总体估计扩展为 测试跨社会群体和国家之间的异质性，评估气候是否同时发生 冲击放大了冲突的影响，并实证检验了农业、经济、卫生和 家族机制。然后，我通过测量冲突和气候影响来检查潜在的选择效应 生育率和儿童死亡率。这些分析还包括一系列补充分析和稳健性 检查，例如成年男性体重指数的分析、冲突和气候影响的非线性测试， 和数据质量评估。这项研究提供了有关营养影响的新的跨国证据 非洲冲突的情况，填补了冲突环境中严重营养不良的证据空白，并整合了新出现的 关于冲突和气候对健康影响的文献。结果将为有关营养安全的辩论提供信息 在广泛冲突和气候变化日益加剧的时期。
