目的 全面了解高海拔地区驻训官兵发生睡眠障碍情况，梳理存在的主要问题，并分析相关影响因素，为以后高海拔驻训时尽可能避免睡眠相关的高危因素提供依据。方法 采用整体抽样法，从担负不同任务的高海拔驻训部队中抽取750名官兵作为研究对象，由经过培训的专业医护人员指导填写《驻训部队睡眠情况问卷调查表》。对被调查者年龄、单位、民族、文化、专业、单位海拔、训练强度、是否发生训练伤或者疾病、是否出现抑郁及睡眠障碍等情况进行统计分析。结果 共回收有效问卷686份，其中290例存在睡眠障碍，占比42.27%.轻度睡眠障碍191例，占65.86%；中度52例，占17.93%；重度47例，占16.21%.影响睡眠的主要因素是年龄、训练伤或疾病以及单位驻地海拔高度。结论 高海拔驻训部队官兵睡眠障碍发生率较高，尤以由低海拔赴高海拔驻训者更为突出。单位驻地海拔、训练伤或疾病及年龄是睡眠障碍发生的主要不可控因素。

Objective This paper aims to comprehensively understand the incidence of sleep disorders among troops undergoing high-altitude stationing and training, sort out main existing problems and analyze relevant influencing factors, thus providing a basis for minimizing high-risk sleep-related factors in the future. Methods A total of 750 officers and soldiers undertaking different tasks were selected as research objects from troops undergoing high-altitude stationing and training using the cluster sampling method, and were guided by trained medical personnel to fill out Questionnaire on Sleep Status of Troops Undergoing Stationing and Training. Statistical analysis was performed on the respondents' age, unit, ethnicity, education level, major, stationing unit altitude, training intensity,incidence of training injuries or diseases, occurrence of depression or sleep disorders. Results A total of 686 valid questionnaires were collected, among which 290 cases(42.27%) had sleep disorders. Among these, 191 cases(65.86%) were mild, 52 cases(17.93%) were moderate, and 47 cases(16.21%) were severe. The main factors affecting sleep were age, training injuries or diseases, and stationing unit altitude. Conclusion The incidence of sleep disorders among troops undergoing high-altitude stationing and training is relatively high, especially among those who deploy from low-altitude to high-altitude areas. The main uncontrollable factors for incidence of sleep disorders are stationing unit altitude, training injuries or diseases and age.
