Evaluation of Fatigue and Sleep Problems in Cabin Crews During the Early COVID-19 Pandemic Period

Abstract

Background: The COVID-19 outbreak has affected the aviation sector. The anxiety and fear caused by this newly emerging virus, whose effects are not fully known in the short and long term, may also cause problems in terms of flight safety. We aimed to evaluate fatigue and sleep problems associated with fear of COVID-19 during the early pandemic period in cabin crew. Methods: This is a cross-sectional survey study consisting of 45 questions in total. Participants were cabin crew members on flight duty. An online questionnaire was sent to 2092 cabin crew in February-April 2021 via TASSA Cabin Crew Member's Association. The survey included questions about socio-demographic characteristics, flight times, flight types and COVID test history, as well as the international physical activity questionnaire-short form (IPAQ-SF), fatigue severity scale (FSS), Jenkins sleep scale (JSS) and fear of COVID-19 scale (FCV-19S). Results: Out of 316 survey results obtained (response rate, 15%), 225 (71%) were included in the study, with a mean age (SD) of 32.54 (4.91) years, and 124 (55.1%) were women. According to IPAQ-SF, 27.6% of cabin crew were found to be inactive, 54.7% minimally active and 17.7% very active. According to FSS, pathological fatigue was found in 43.6%. The FSS score of the inactive group was higher than the others (Kruskal Wallis, p < 0.001). As the number of people living in the same house or flight time in the last 1 month increase, the fear of COVID-19 also increases (Spearman, p = 0.01 r = 0.171, and p = 0.049 r = 0.131). In addition, there was direct correlation between fear of COVID-19 and fatigue and sleep problems (Spearman, p = 0.001 r = 0.218, and p < 0.001 r = 0.26, respectively). Conclusion: This study shows that fatigue and sleep problems increase as the fear of COVID-19 increases in cabin crew during the early pandemic period. Consequently, precautions and further studies are needed, as fatigue and sleep disorders may primarily be related to the anxiety, fear and uncertainty surrounding the COVID-19 pandemic.
