ASSESSMENT OF THE CORRELATION BETWEEN PULMONARY FUNCTION AND COGNITIVE IMPAIRMENT IN OCCUPATIONAL HIGH-RISK WORK ENVIRONMENTS
Bibliographic record
Abstract
Objectives: This study aimed to investigate the correlation between pulmonary function and cognitive performance, assessed through pulmonary function tests (PFTs) and Montreal Cognitive Assessment (MoCA), among workers in high-risk occupational environments. Methods: A cross-sectional study was conducted from March 2024 to January 2025 in Chennai, Tamil Nadu, involving 180 male participants (aged 30–55 years) from five occupational groups (carpenters, construction workers, drivers, painters, and welders) and a control group (computer programmers). PFTs measured forced vital capacity (FVC), forced expiratory volume in 1 s (FEV₁), FEV₁/FVC ratio, and peak expiratory flow (PEF) pre- and post-shift. Cognitive function was assessed using the MoCA, evaluating visuospatial/executive function by the trail making test, naming, attention, language, abstraction, delayed recall, and orientation. Data were analyzed using one-way ANOVA, post hoc Tukey’s tests, and the Kruskal– Wallis test, with statistical significance set at p<0.05. Results: Significant post-shift declines in pulmonary parameters (FVC, FEV₁, PEF, and maximum voluntary ventilation) were observed across all occupational groups (p<0.001), with carpenters and construction workers showing the most pronounced reductions. MoCA scores revealed significant inter-group differences in visuospatial/executive function, language, attention, delayed recall, and orientation (p<0.01). Painters and drivers outperformed carpenters and construction workers in most cognitive domains. The control group exhibited superior pulmonary and cognitive performance. A significant inverse correlation was found between reduced pulmonary function and cognitive deficits, particularly in language and delayed recall. Conclusion: Occupational exposure in high-risk environments is associated with acute pulmonary function decline and specific cognitive impairments, suggesting shared pathophysiological mechanisms such as inflammation and oxidative stress. Routine integration of cognitive and pulmonary assessments in occupational health surveillance is recommended to detect early functional decline and inform intervention strategies.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
