Larger Airway Functions in Poultry and Dairy Confinement Workers: A Cross-Sectional Study.

BACKGROUND

The peak expiratory flow (PEF) test is a crucial tool for assessing larger airway functions, particularly in individuals exposed to occupational hazards. This study aims to compare PEF values between animal workers (poultry and dairy farm workers) who are regularly exposed to animal allergens and other respiratory irritants and normal workers who do not have such exposures.

METHODS

A cohort of animal workers from poultry and dairy farms were evaluated alongside a control group of normal workers without known respiratory hazards. PEF measurements were taken using a computerized spirometer, and results were analyzed to determine differences in respiratory function between the two groups.

RESULTS

There was a significant difference in PEF values, with animal workers exhibiting lower PEF compared to their control group. Further, poultry farm workers had a significant decrease in PEF when compared to dairy farm workers. This study represents a pioneering effort in the comparative analysis of respiratory health among workers in poultry and dairy farms.

CONCLUSIONS

The findings indicate that occupational exposure to allergens and irritants associated with animal environments may have deleterious effects on respiratory health. Further analysis, controlling for confounding variables such as smoking status, age, and baseline health conditions, reinforces the initial observation of compromised respiratory function in animal workers. This study underscores the importance of regular respiratory health monitoring and implementation of protective measures for individuals in occupations with high exposure to respiratory irritants. Enhanced awareness and preventive strategies could mitigate the long-term health impacts on animal workers, ensuring safer working environments and improved overall health outcomes.
