飞行人员静脉血栓栓塞症预防认知现状及影响因素分析

Pilots’knowledge of prevention of venous thromboembolism and influencing factors

目的了解飞行人员对静脉血栓栓塞症形成的相关知识、预防态度现状,探讨其影响因素,为飞行人员静脉血栓栓塞症精准预防提供依据。方法随机抽样法选取3个机种的412名飞行人员进行问卷调查,统计数据,进行多因素Logistic回归分析,筛选主要影响因素。结果进行单因素Logistic分析后,筛选出飞行年限、总飞行时间、每次飞行时间、持续坐姿时间4个影响因素。多因素Logistic回归分析表明,飞行人员持续坐姿时间、飞行年限是影响其静脉血栓栓塞症的重要因素(P<0.05)。412名飞行人员掌握静脉血栓栓塞症预防知识正确率平均得分为34.55%,预防态度正确率平均得分为96.72%。结论飞行人员对静脉血栓栓塞症的认知总体处于偏下水平,应提高其知识普及率,增强预防意识。

Objective To provide data for precise prevention of venous thromboembolism among pilots by finding out about pilots’amount of knowledge of and attitudes towards the formation of venous thromboembolism.Methods A total of 412 pilots from 3 aircraft types were randomly selected to conduct a questionnaire survey.The key factors that affected the incidence of venous thromboembolism were identifiedvia multi-factor logistic regression analysis.Results The single factor Logistic regression analysis screened four factors,including years of flight,total time of flight,length of time per flight and duration of continuous sitting.Multi-factor logisticregression analysis showed that the flight crew’s duration of continuous sitting and years of flight were the key factorsaffecting their incidence of venous thromboembolism(P<0.05).The correct rate of these pilots’related knowledge of venous thromboembolism stood at 34.55%,compared with 96.72%for the attitude to prevention.Conclusion Pilots generally have a relatively poor knowledge of the formation of venous thromboembolism,so they should be better informed of this disease and have a better idea of prevention.
