Night flights might aggravate sleep disorders among aging airline pilots, posing a threat to flight safety. In this study, we assess the prevalence of sleep disorders as well as the combined effects of night flight duration and aging on sleep disorders.
A cross-sectional study was conducted between July and December, 2021. Participants were recruited from a commercial airline. Sleep disorders were evaluated using the Pittsburgh Sleep Quality Index (PSQI). The interaction effect of night flight duration and age on sleep disorders and their correlates were examined using logistic regression models.
In total, 1,208 male airline pilots were included in the study, with a median age of 34 (interquartile range [IQR]: 29-39) years. The overall prevalence of sleep disorders was 42.6%. The multivariate logistic regression identified an interaction between night flight duration and age on sleep disorders (adjusted odds ratio [aOR] of the interaction term was 5.85 95% CI: 2.23-15.34 for age ≥ 45 years; 1.96 95% CI:1.01-3.81 for the age group 30-44 years). Longer night flight duration (aOR: 4.55; 95%CI: 1.82-11.38) and body mass index (BMI) ≥28.0 kg/m (aOR: 0.16; 95% CI: 0.03-0.91) were significantly associated with sleep disorders in participants aged ≥45 years. Hyperuricemia (aOR: 1.54; 95% CI: 1.09-2.16) and regular exercise (aOR: 0.23; 95% CI: 0.08-0.70) were significantly associated with sleep disorders in the 30-44 years age group.
The mean monthly night flight duration and aging had a synergistic effect on airline pilots' sleep disorders, implying an aging and work-related mechanistic pathogenesis of sleep disorders in airline pilots that requires additional exploration and intervention.
夜间飞行可能会加重老年航空公司飞行员的睡眠障碍，对飞行安全构成威胁。在本研究中，我们评估了睡眠障碍的患病率以及夜间飞行时长和衰老对睡眠障碍的综合影响。
于2021年7月至12月进行了一项横断面研究。参与者从一家商业航空公司招募。使用匹兹堡睡眠质量指数（PSQI）评估睡眠障碍。使用逻辑回归模型检验夜间飞行时长和年龄对睡眠障碍及其相关因素的交互作用。
本研究共纳入1208名男性航空公司飞行员，中位年龄为34岁（四分位间距[IQR]：29 - 39岁）。睡眠障碍的总体患病率为42.6%。多因素逻辑回归确定了夜间飞行时长和年龄对睡眠障碍存在交互作用（交互项的调整优势比[aOR]：年龄≥45岁时为5.85，95%置信区间[CI]：2.23 - 15.34；30 - 44岁年龄组为1.96，95%CI：1.01 - 3.81）。在年龄≥45岁的参与者中，更长的夜间飞行时长（aOR：4.55；95%CI：1.82 - 11.38）和体重指数（BMI）≥28.0kg/m²（aOR：0.16；95%CI：0.03 - 0.91）与睡眠障碍显著相关。在30 - 44岁年龄组中，高尿酸血症（aOR：1.54；95%CI：1.09 - 2.16）和规律运动（aOR：0.23；95%CI：0.08 - 0.70）与睡眠障碍显著相关。
每月平均夜间飞行时长和衰老对航空公司飞行员的睡眠障碍有协同作用，这意味着航空公司飞行员睡眠障碍存在与衰老和工作相关的机制性发病原因，需要进一步探索和干预。
