背景资料：由于数百万人营养不良和水资源不足，FI和WI仍然是对全球健康至关重要的主题。现有的一维FI和WI指标并不都能捕捉到类似的多维方面，从而限制了我们评估和解决粮食和水相关问题的能力。研究方法：使用卫生，卫生和婴儿营养功效（SHINE）试验数据，我们的研究以捕获其关键维度的方式分别对家庭FI（N = 3551）和WI（N = 3311）进行了概念化。我们制定了措施的FI和WI的农村津巴布韦家庭的基础上，多个对应分析（MCA）的分类数据。结果如下：三个FI尺寸被保留：“穷人的食物获取”，“家庭冲击”和“低食品质量和可用性”，因为是三个WI尺寸：“穷人的水获取”，“水质差”，和“低水的可靠性”。在基线和18个月时使用验证性因素分析（CFA）对多维模型的内部效度进行评估。维度得分与一组外生变量（SES，HIV状态，季节，抑郁，感知健康，食品援助，水收集），另外还表明预测，收敛和判别效度。结论：FI和WI尺寸足够不同，可以通过单独的指标进行表征。这些指标对于确定具体的不安全问题以及寻找改善健康和营养干预措施的新目标至关重要。
Background: With millions of people experiencing malnutrition and inadequate water access, FI and WI remain topics of vital importance to global health. Existing unidimensional FI and WI metrics do not all capture similar multidimensional aspects, thus restricting our ability to assess and address food- and water-related issues. Methods: Using the Sanitation, Hygiene and Infant Nutrition Efficacy (SHINE) trial data, our study conceptualizes household FI (N = 3551) and WI (N = 3311) separately in a way that captures their key dimensions. We developed measures of FI and WI for rural Zimbabwean households based on multiple correspondence analysis (MCA) for categorical data. Results: Three FI dimensions were retained: ‘poor food access’, ‘household shocks’ and ‘low food quality and availability’, as were three WI dimensions: ‘poor water access’, ‘poor water quality’, and ‘low water reliability’. Internal validity of the multidimensional models was assessed using confirmatory factor analysis (CFA) with test samples at baseline and 18 months. The dimension scores were associated with a group of exogenous variables (SES, HIV-status, season, depression, perceived health, food aid, water collection), additionally indicating predictive, convergent and discriminant validities. Conclusions: FI and WI dimensions are sufficiently distinct to be characterized via separate indicators. These indicators are critical for identifying specific problematic insecurity aspects and for finding new targets to improve health and nutrition interventions.
