Brewis, Workman et al. (2020) provided a basis for significant subsequent advancement in understanding the interplay between household water insecurity and food insecurity across diverse global contexts. This commentary reflects on the subsequent evolution of research and its application in the 5 years since the study's initial online publication in AJHB, highlighting dynamic mechanisms that link water insecurity and food insecurity and the implications for human health. Newer studies suggest that water insecurity may drive food insecurity more significantly than vice versa, with localized case studies revealing the diversity and complexity of multi-scalar factors that contribute to these relationships. Future research priorities include more refined water insecurity measurement tools and further testing of potential mechanisms in theorized causal pathways linking water insecurity and food insecurity to each other and health outcomes.
布鲁伊斯、沃克曼等人（2020年）为后续在理解全球不同背景下家庭用水不安全与粮食不安全之间的相互作用方面取得重大进展奠定了基础。本评论文章反思了自该研究最初在《美国人类生物学杂志》在线发表后的5年里研究的后续演变及其应用，强调了将用水不安全与粮食不安全联系起来的动态机制以及对人类健康的影响。最新研究表明，用水不安全可能比粮食不安全更显著地导致粮食不安全，局部案例研究揭示了促成这些关系的多尺度因素的多样性和复杂性。未来的研究重点包括更精确的用水不安全测量工具，以及进一步测试将用水不安全与粮食不安全相互联系并与健康结果相关的理论因果途径中的潜在机制。
