Effects of an alternating work shift on air traffic controllers and the relationship with excessive daytime sleepiness and stress
Efeitos do turno de trabalho alternado em controladores de tráfego aéreo e relação com sonolência diurna excessiva e estresse
ABSTRACT
Objective: To evaluate symptoms of stress and excessive daytime sleepiness (EDS) in air traffic control (ATC) officers in Brazil.
Methods: Fifty-two ATC officers participated, based at three air traffic control units, identified as A, B and C. Stress symptoms were assessed using the Lipp Inventory of Stress Symptoms for Adults, and EDS by the Epworth Sleepiness Scale.
Results: The sample mean age was 37 years, 76.9% of whom were male. Excessive daytime sleepiness was identified in 25% of the ATC officers, with 84.6% of these based at air traffic control unit A, which has greater air traffic flow, operating a 24-hour alternating work shift schedule. A total of 16% of the ATC officers had stress symptoms, and of these, 62% showed a predominance of physical symptoms.
Conclusion: The high percentage of ATC officers with EDS identified in group A may be related to chronodisruption due to night work and alternating shifts.
RESUMO
Objetivo: Avaliar sintomas de estresse e sonolência diurna excessiva (SDE) em controladores de tráfego aéreo (CTA) do Brasil.
Métodos: Participaram 52 controladores pertencentes a 3 órgãos de controle de tráfego aéreo, denominados de A, B e C. Os sintomas de estresse, foram avaliados pelo Inventário de Sintomas de Estresse para Adultos, a SDE pela Escala de Sonolência Epworth.
Resultados: 76,9% da amostra são do sexo masculino, com média de idade de 37 anos. SDE foi identificada em 25% dos controladores, desses 84,6%, pertencem aos órgãos de controle de tráfego aéreo A, caracterizado por maior movimento de aeronaves, funcionamento 24 horas e escala de serviço em turnos alternantes. Um total de 16% dos controladores apresentam sintomas de estresse, desses, 62% mostraram o predomínio de sintomas físicos.
Conclusão: A porcentagem elevada de CTA com SDE identificada no grupo A pode estar relacionada a cronodisrupção devido ao trabalho noturno e alternado.
