Associating Dietary Sustainability with Health: A Focus on General and Central Adiposity.
Article in International journal of environmental research and public health, 2026. 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
This study aims to explore the relationship between the Diet Sustainability Score (DSS) and health outcomes, specifically body mass index (BMI) and waist-to-height ratio (WHtR). Using data from 2287 Portuguese adults in the National Food, Nutrition, and Physical Activity Survey (IAN-AF 2015-2016), DSS was calculated based on four dimensions: health-related nutritional attributes, environmental impact, economic affordability, and sociocultural acceptability. Logistic regression models were used to analyse associations between DSS and general adiposity (BMI classes: under/normal weight vs. overweight/obesity) and central adiposity (WHtR classes: healthy vs. unhealthy central adiposity). Models were adjusted for sex, age, education and physical activity level to control for potential confounders. Higher DSS is associated with reduced odds of overweight/obesity (OR = 0.91, 95%CI: 0.88, 0.94), and unhealthy central adiposity (OR = 0.91, 95%CI: 0.87, 0.95), suggesting that more sustainable dietary patterns are associated with more favourable adiposity profiles. This study highlights the importance of promoting sustainable diets as part of public health strategies aimed at addressing obesity and integrating health, environmental, economic, and sociocultural dimensions for more comprehensive, long-term population health improvements.
