Water, food, and mental well-being: Associations between drinking water source, household water and food insecurity, and mental well-being of low-income pregnant women in urban Mozambique.
Article in PLOS water, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Drinking water access and water and food insecurity have been linked to mental well-being, but few studies have comprehensively assessed potential pathways linking these associations. Understanding these mediation pathways is particularly important among pregnant women, as prenatal stress and poor mental well-being have been shown to negatively impact fetal development. In this study, we address this gap by analyzing the relationships between drinking water source and water and food insecurity with mental well-being amongst pregnant women living in low-income, urban neighborhoods of Beira, Mozambique. Data for this cross-sectional analysis were collected among third-trimester, pregnant women (n=740) from February 2021 through October 2022 as part of a matched cohort study. Validated, cross-cultural measures of mental well-being and household water and food insecurity were administered in the survey. Drinking water source was determined by presence of a household drinking water source on-premises. We used logistic regression to characterize the associations between drinking water source, water and food insecurity, and mental well-being and causal mediation analysis to determine mediation by food and water insecurity along these pathways. We found evidence that water insecurity (OR 1.44; 95%CI 1.02, 2.02) and food insecurity (OR 2.27; 95%CI 1.57, 3.34) were individually associated with adverse mental well-being. Drinking water source was not associated with mental well-being (OR 1.00; 95%CI 0.71, 1.39), water insecurity (OR 0.86; 95%CI 0.60, 1.24), or food insecurity (OR 1.02; 95%CI 0.71, 1.47). Food insecurity may also mediate the relationship between water insecurity and mental well-being (ACME 0.05; 95%CI 0.02, 0.07; ADE 0.04; 95%CI -0.04, 0.13). Our findings support growing literature that water and food insecurity are important to mental well-being, a key aspect of overall health. Further research is needed to confirm causality along these pathways and determine specific mechanisms through which these interactions take place.
