粮食和水不安全已被证明是急性和慢性压力因素，并损害人类健康和发展。一个未经检验的基本命题是，它们长期共存，家庭用水无保障是家庭粮食无保障的一个根本驱动因素。我们提供了一个初步的评估，他们的协会使用的横截面数据从27个站点高度不同形式的水不安全在21个低收入和中等收入国家在非洲，亚洲，中东和美洲（N = 6691户）。家庭粮食不安全及其子领域（粮食数量，粮食质量和粮食焦虑）估计使用家庭粮食不安全获取规模;水不安全和子领域（数量，质量和机会成本）估计基于类似的自我报告的数据。在多水平广义线性混合效应模型（GLMM）中，综合水不安全评分与粮食不安全的所有子领域的较高分数相关。农村家庭能够更好地缓冲水不安全对粮食数量的影响，而城市家庭能够更好地缓冲水不安全对粮食质量的影响。同样，水不安全的所有子领域的得分越高，家庭粮食不安全程度越高。考虑到建模中包含的站点的多样性，模式化支持一个基本理论：家庭水不安全与家庭粮食不安全长期共存。水不安全是粮食不安全的一个更合理的驱动因素，而不是匡威。这些研究结果直接挑战了发展做法，在这些做法中，家庭粮食安全干预措施往往与水安全干预措施分开实施。
Food and water insecurity have both been demonstrated as acute and chronic stressors and undermine human health and development. A basic untested proposition is that they chronically coexist, and that household water insecurity is a fundamental driver of household food insecurity. We provide a preliminary assessment of their association using cross-sectional data from 27 sites with highly diverse forms of water insecurity in 21 low- and middle-income countries across Africa, Asia, the Middle East, and the Americas (N = 6691 households). Household food insecurity and its subdomains (food quantity, food quality, and anxiety around food) were estimated using the Household Food Insecurity Access Scale; water insecurity and subdomains (quantity, quality, and opportunity costs) were estimated based on similar self-reported data. In multilevel generalized linear mixed-effect modeling (GLMM), composite water insecurity scores were associated with higher scores for all subdomains of food insecurity. Rural households were better buffered against water insecurity effects on food quantity and urban ones for food quality. Similarly, higher scores for all subdomains of water insecurity were associated with greater household food insecurity. Considering the diversity of sites included in the modeling, the patterning supports a basic theory: household water insecurity chronically coexists with household food insecurity. Water insecurity is a more plausible driver of food insecurity than the converse. These findings directly challenge development practices in which household food security interventions are often enacted discretely from water security ones.
