Exposure to armed conflict, climate shocks, and the nutritional status of women and children

项目总结 该项目将研究暴露在武装冲突中如何影响#年妇女和儿童的营养状况。 撒哈拉以南非洲。我链接了撒哈拉以南35个国家的725,619名妇女和484,546名儿童的营养数据 非洲国家在生理上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个月儿童体重/身高、儿童年龄/年龄身高的影响 24-59个月和15-49岁女性的体重指数，同时控制相关因素 人口统计特征和时空混杂因素。我将对冲突影响的总体估计扩大到 测试社会群体和国家之间的异质性，评估同时存在的气候 冲击放大了冲突的影响，并经验性地检验了农业、经济、卫生和 家族性机制。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。分析还包括一系列补充分析和稳健性 检查，如成年男性体重指数分析，冲突中的非线性测试和气候影响， 以及对数据质量的评估。这项研究为营养效应提供了新的跨国证据。 关于非洲冲突的研究，填补了关于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。这一结果将为有关营养安全的辩论提供信息 在一个广泛冲突和气候变化无常的时期。

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.
