Associations between burnout, sociodemographic factors, health behaviors, and obesity indices in Spanish employees.
Article in AIMS 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
Background: Obesity remains a major global health concern, and psychosocial stressors such as burnout may contribute to its development. While lifestyle and sociodemographic factors are recognized determinants, their interaction with burnout has been less studied, especially using advanced adiposity indices. In this study, we assessed the associations between burnout, sociodemographic variables, lifestyle habits, and obesity in a large cohort of Spanish employees. Methods: We performed a cross-sectional analysis of Spanish workers undergoing occupational health examinations. Burnout was classified into low, moderate, and high levels. Obesity was assessed using body mass index (BMI), waist-to-height ratio (WtHR), the Clínica Universidad de Navarra Body Adiposity Estimator (CUN-BAE), and the Metabolic Score for Visceral Fat (METS-VF). Logistic regression models adjusted for sociodemographic and behavioral variables were applied, including interaction analyses. Results: Burnout showed a strong and graded association with obesity across all indices. Compared with low burnout, high burnout was associated with up to a 40% higher odds of obesity by BMI, and even stronger associations when using CUN-BAE and METS-VF. Women, older employees, and those from lower social classes were disproportionately affected. Adherence to a Mediterranean diet and engagement in regular physical activity were associated with lower obesity risk among participants with higher burnout levels. Conclusions: Burnout is a significant and independent correlate of obesity in working populations, particularly when measured with indices capturing visceral fat. Vulnerable groups, women, older workers, and lower social classes, -require targeted interventions. Workplace health programs should integrate stress management with lifestyle promotion as dual strategies to combat obesity. Longitudinal research is needed to confirm causality and assess intervention effectiveness.
