Obesity and Its Relation to Excessive Daytime Sleepiness in Civilian Pilots.

Abstract

INTRODUCTION: Excessive daytime sleepiness (EDS) is often associated with decreased work performance and fatigue in civil pilots. However, aeromedical recommendations for the evaluation of EDS are associated with suspicion of obstructive sleep apnea (OSA). Currently, many studies have found an association between obesity and EDS, regardless of OSA. This study aims to determine whether there is a relationship between obesity and EDS in Indonesian civilian pilots, as well as its risks for developing OSA.METHODS: This study used a cross-sectional design and was carried out at the Directorate General Civil Aviation Medical. Subjects were asked to fill out questionnaires, including the Epworth Sleepiness Scale to measure EDS and STOP-Bang to assess OSA risk, followed by anthropometric measurements for body mass index (BMI) and waist circumference as obesity indicators.RESULTS: A total of 156 subjects were obtained, with an EDS prevalence of 16.7%. There was no significant relationship between obesity and EDS, but the prevalence of EDS was higher in obese subjects based on waist circumference than based on BMI (17.8% vs. 15.6%). Most obese pilots with EDS had a low risk of OSA (83.3% and 80%).CONCLUSION: The prevalence of EDS was found to be higher in pilots with central obesity compared to BMI-categorized obesity. The incidence of EDS was not correlated with the risk of OSA.Brahmanti RS, Sampurna B, Ibrahim N, Adi NP, Siagian M, Werdhani RA.
