Household water security and infant feeding practices in Mexico: insights from the ENSANUT 2021 survey.
Article in BMC public health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundWater security (WS) and improved socioeconomic conditions are crucial for child nutrition. However, limited research has explored the association between WS and infant and young child feeding (IYCF) practices in low- and middle-income countries. This study aimed to assess the relationship between household WS and IYCF practices in Mexican children aged 0-35 months.
methodsData from 939 children from the 2021 Mexican National Health and Nutrition Survey were analyzed. Logistic regressions assessed associations between WS and IYCF indicators, considering interactions by area type, region, and wealth tertile.
findingsThe final sample represents 5,256,872 children nationwide. Water insecurity affected 23.1% of children in the lowest wealth tertile and 36.4% of those in food-insecure households. Water-secure children had better IYCF practices: 95.7% had ever been breastfed, and 79.5% met minimum dietary diversity (MDD) and minimum meal frequency (MMF). Analytically, children in urban water-secure households were 72% less likely to have ever been breastfed than those in water-insecure households. Water-secure households in the southern region were 2.84 times more likely to meet MDD, while those in low-wealth conditions were 2.71 times more likely to achieve MMF (OR = 2.71, 95% CI: 1.13-6.52, p = 0.03).
conclusionsThese findings highlight the complex role of WS in IYCF. While WS improves MDD and MMF, it may also influence breastfeeding patterns, particularly in urban areas where formula feeding is more common. Ensuring equitable access to safe water should be a priority, alongside strategies that promote and protect breastfeeding in different socioeconomic contexts.
