中文摘要：

目的：探索影响歼击机飞行员睡眠质量的相关危险因素，为改进飞行员睡眠质量提供临床依据。方法以整群随机抽样方法抽取347名歼击机飞行员，采用自制问卷与匹兹堡睡眠质量指数量表（Pittsburgh sleep quality index ，PSQI）相结合形式，对飞行员睡眠质量进行横断面调查研究。以PSQI总分≥7分作为睡眠障碍组，PSQI总分＜7分为对照组，对飞行员睡眠质量进行相关因素分析。结果得到有效样本330例，飞行员睡眠障碍发生率为19．4％，Logistic多因素回归分析显示，睡眠不良家族史、躯体疾病、工作生活压力大（OR＝4．060、4．007、2．868）是睡眠障碍的危险因素。睡眠障碍组的胃炎、颈椎病、腰椎病、头痛、胃食管反流病的患病率高于对照组，差异均有统计学意义（P＜0．05）。结论歼击机飞行员睡眠障碍发生率比较高，与工作生活压力、躯体疾病、家族史等因素密切相关，应给予针对性的干预措施。

英文摘要：

Objective To analyze the risk factors of sleep disorder in fighter pilots for improving their sleep quality . Methods Three hundred and forty‐seven fighter pilots were selected by cluster random sampling ,and were investigated by using self‐made questionnaire combined with pittsburgh sleep quality index （PSQI） questionnaire .The subjects were divided into sleep disorder group （PSQI score≥ 7） and control group （PSQI score 〈 7） to analyze the risk factors influencing their sleep quality .The data was analyzed by a Logistic regression model . Results Three hundred and thirty feedbacks were valid . The prevalence of sleep disorder was 19 .4% . Logistic regression analysis showed that family history of sleep disorder （OR= 4 .060） ,physical diseases （OR= 4 .007） ,over pressure from work and life （OR = 2 .868） were the risk factors influencing sleep quality . The incidences of gastroenteritis ,cervical diseases ,lumbar diseases ,headache and gastroesophageal reflux disease in sleep disorder group were significantly higher than those in control group （ P〈 0 .05 ） . Conclusions The prevalence of sleep disorder in fighter pilots is comparatively high ,and that is closely related to such risk factors as overpressure ,physical diseases and family disorder history .The corresponding interventions should be taken to improve their sleep quality .
