Association between the diagnosis of diet-related non-communicable diseases and the use of nutritional labeling among Mexican, Mexican American, and non-Mexican American adults: a cross-sectional study from the International Food Policy Study 2021-2022.
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
backgroundDiet-related non-communicable diseases (NCDs) are major global health concerns. Front-of-package warning labels (WLs) and nutrition facts labels (NFLs) aim to promote healthier food choices, yet their use among individuals with NCDs and across populations remains underexplored. This study uniquely compares two labeling systems (WL and NFL) and examines the association between NCD diagnosis and label use among Mexican, Mexican American, and non-Mexican American adults.
methodsCross-sectional data from the 2021–2022 International Food Policy Study were analyzed. Self-reported WL and NFL use and NCD diagnoses (diabetes, hypertension, heart disease, high cholesterol, cancer) were examined using multivariate logistic regression models adjusting for sociodemographic and health-related confounders.
resultsAmong 23,951 adults, NFL use was highest among non-Mexican Americans (80.1%) and lowest among Mexicans (69.8%, p < 0.01). NFL use was significantly associated with diabetes and multiple NCDs in non-Mexican Americans. Specifically, non-Mexican Americans diagnosed with diabetes were 68% more likely to use the NFL (AOR 1.68, 99% CI: 1.26–2.24) compared to those without an NCD diagnosis. Furthermore, non-Mexican Americans with 3 or more NCDs were 48% more likely to use the NFL (AOR 1.48, 99% CI: 1.07–2.06). In Mexico, WL use (77.4%) exceeded NFL use (69.8%). Mexicans with high cholesterol were more likely to perceive the “Excess Sodium” label as the most useful (AOR 1.89, 99% CI: 1.15–3.12), while those with diabetes found the “Excess Sugar” label particularly helpful (AOR 1.65, 99% CI: 1.07–2.54).
conclusionsLabeling use varied across populations and NCD status. These findings highlight the potential of interpretive front-of-package labels to support informed food choices, particularly among individuals with NCDs, and to strengthen public health strategies that promote healthier dietary behaviors.
