Discussion

Cross-sectional study shows 72.2% of workers post-COVID-19 have spirometric abnormalities, indicating an urgent need for respiratory monitoring.

MAIN FINDING: Over 72% of workers with a history of COVID-19 showed spirometric abnormalities related to high altitude exposure.
KEY EVIDENCE: 40.5% had a mixed pattern, 20.8% restrictive, and 11.0% obstructive spirometry issues.
APPROACH: A cross-sectional study involved 400 workers born at sea level exposed to altitudes above 2500 meters.
SIGNIFICANCE: Findings highlight the importance of monitoring respiratory health in workers exposed to high altitude after COVID-19.

Góngora-Bendezú et al. (2025) studied this question.
