This study identifies multiple pathways connecting household water insecurity with child nutrition. Using nationally representative samples for 18 countries, we examine the mediating role of child's dietary diversity as a function of household water status, while also accounting for sanitation. We construct a latent household water insecurity score (HWI) and use Structural Equation approach to model underlying pathways. HWI affected child's HAZ score and hemoglobin both directly and indirectly, with a mediation from child feeding alongside effects from sanitation. Broadening the conception of household water insecurity and accommodating the indirect effects of water could improve explanations of child under-nutrition.
本研究确定了多个将家庭用水不安全与儿童营养联系起来的途径。我们使用 18 个国家的全国代表性样本，检验了儿童饮食多样性作为家庭用水状况的函数的中介作用，同时也考虑了卫生因素。我们构建了一个潜在的家庭用水不安全评分（HWI），并使用结构方程方法来模拟潜在的途径。HWI 直接和间接地影响了儿童的 HAZ 评分和血红蛋白，同时也受到儿童喂养和卫生条件的影响。拓宽家庭用水不安全的概念并考虑水的间接影响，可以提高对儿童营养不良的解释能力。
