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.

项目摘要 该项目将研究武装冲突如何影响非洲妇女和儿童的营养状况， 撒哈拉以南非洲我将撒哈拉以南35个国家的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的冲突记录。然后我测量了 冲突暴露对0 - 23个月儿童的体重-身高比， 24 - 59个月，15 - 49岁女性的体重指数，同时控制相关的 人口统计学特征和时空混杂因素。我将冲突影响的总体估计扩展为 测试社会群体和国家之间的异质性，评估同时发生的气候变化是否 冲击放大了冲突的影响，并从经验上研究了农业，经济，卫生和 家庭机制。然后，我通过测量冲突和气候对 生育率和儿童死亡率。分析还包括一系列补充分析和稳健性分析。 检查，如成年男性体重指数分析，冲突和气候影响的非线性测试， 和数据质量评估。这项研究提供了关于营养影响的新的跨国证据 在非洲的冲突，填补了关于在冲突环境中严重营养不良的证据缺口，并纳入了新出现的 关于冲突和气候对健康影响的文献。研究结果将为关于营养安全的辩论提供信息 在冲突蔓延和气候多变的时期。
