Metabolic and Anthropometric Factors Outperform Psychomotor Vigilance Task in Predicting Obstructive Sleep Apnea in Pilots: A LASSO-Based Analysis

The core predictors for OSA in pilots are primarily indicators of metabolic syndrome, notably BMI and FPG. A framework based on the six physiological factors identified by LASSO regression provides a solid evidence-based foundation for developing an efficient and accurate OSA screening tool. In this study cohort, the PVT, as a measure of cognitive performance, demonstrated limited predictive value and is not recommended as a primary screening tool for OSA in pilots.
