Association between ultra-processed food consumption and perceived stress among teaching professionals: a gender-stratified cross-sectional study from Urban India.

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: Ultra-processed foods (UPFs) have become deeply embedded in contemporary dietary patterns, particularly among urban working populations. Concurrently, perceived stress especially in high-demand occupations such as teaching has emerged as a significant public health concern. Understanding the relationship between UPF consumption and perceived stress is essential for designing targeted nutritional and mental health interventions. Objective: This study investigated the association between ultra-processed food consumption and perceived stress levels among teaching professionals, with specific attention to gender-related differences in dietary behavior and stress experience. Methods: A cross-sectional analytical study was conducted among 549 teaching professionals from educational institutions across urban India. UPF consumption was quantified using a validated 20-item binary-scored instrument aligned with the NOVA classification system. Participants were stratified into Low ( ≤ 8 items; Results: Mean PSS-10 scores increased progressively across Low (2.77 ± 0.54), Moderate (3.01 ± 0.36), and High (2.97 ± 0.32) UPF consumption groups. Welch-corrected Conclusion: Higher UPF consumption was significantly but modestly associated with elevated perceived stress among teaching professionals. The observed association is consistent with mechanistic pathways described in prior experimental literature, including gut-brain axis disruption and neuroendocrine dysregulation; however, these mechanisms were not empirically tested in the present study. Female educators demonstrated disproportionately higher stress burden. Findings support incorporating dietary behavior as a modifiable target within occupational wellness strategies for educators. Longitudinal, biomarker-inclusive, and gender-stratified research is warranted to establish directionality, test inflammatory and gut-brain mechanisms, and develop evidence-based occupational wellness interventions.
