Abstract:
Objective To investigate the sleep quality of civil aviation pilots and provide reference and basis for ensuring the sleep health of pilots. Methods A cross-sectional cluster sampling questionnaire was used.The Pittsburgh sleep quality index (PSQI) scale and self-made questionnaires were used to investigate and evaluate the sleep status of the active pilots of an airline company.Each component of PSQI was scored by 0 ,1 ,2 ,or 3 points ,and the cumulative score of 7 components was the total score of PSQI.If a PSQI component was scored as 2 or 3 points it would indicate a poor or very poor quality of the component.PSQI ＞ 7 meant poor sleep quality , and PSQI ≤7 meant good sleep quality. Results The average score of pilots′ PSQI was 8.09 ± 3.47. The mean scores of PSQI component were 1.53 ± 0.80 for sleep quality ,1.45 ± 0.93 for time to fall asleep ,1.39 ± 0.97 for sleep time ,0.38 ± 0.73 for sleep efficiency ,1.22 ± 0.58 for sleep disorder , 0.11 ± 0.47 for hypnotic drug ,and 2.00 ± 1.06 for daytime dysfunction.The distribution by frequency that for the PSQI component ≥2 was daytime dysfunction (66.2%) ,sleep quality (52.9%) ,sleep time (48.8%) and time to fall asleep (48.5%) respectively.55.6% of civil aviation pilots showed sleep quality problems. Conclusions The sleep quality problem of civil aviation pilots is serious and should be highly concerned and actively intervened.
