目的 :探讨青藏铁路现场管理人员的血氧饱和度 (SaO2 )、睡眠质量、心理健康状况及其影响因素。方法 :采用随机整群抽样 ,应用Dash2 0 0 0型生理多参数监护仪、匹兹堡睡眠质量指数 (PSQI)问卷和症状自评量表 (SCL -90 ) ,对青藏铁路现场管理人员 117人进行现场测评 ,并与重庆地区铁路工程现场管理人员 90人比较。结果 :青藏铁路现场管理人员收缩压、舒张压较高 ,SaO2 较低 ,PSQI总分及习惯性睡眠效率、使用睡眠药物两因子分及SCL -90总分及各因子得分较高 ,与非住藏铁路现场管理人员比较均有统计学差异。多因素分析结果显示白天功能紊乱、睡眠紊乱、睡眠持续性和年龄是影响受试心理健康水平的相关因素。结论 :青藏铁路现场管理人员心理健康水平和睡眠状况明显差于非住藏铁路工程管理人员 ,睡眠是影响心理健康的重要因素。
Objective: To explore the oxygen saturation (SaO2), sleep quality, mental health status and its influencing factors in Qinghai-Tibet Railway site managers. Methods: A total of 117 field management personnel from Qinghai-Tibet Railway were surveyed by random cluster sampling using the Dash2006 physiological multi-parameter monitor, the Pittsburgh Sleep Quality Index (PSQI) questionnaire and the Symptom Checklist 90 (SCL-90) Evaluation, and Chongqing area railway project site managers compared 90. Results: The site managers of Qinghai-Tibet Railway had higher systolic blood pressure, higher diastolic blood pressure, lower SaO2, PSQI total score and habitual sleep efficiency, two scores of sleep medication and SCL-90 total scores and scores of each factor, Tibet railway site managers were statistically significant differences. Multivariate analysis showed that daytime dysfunction, sleep disorders, sleep duration and age were the factors that affected the mental health of the subjects. Conclusion: The mental health status and sleep status of the site managers in Qinghai-Tibet Railway are obviously worse than those of non-resident railway project managers. Sleep is an important factor affecting mental health.
