不同高原地区返回同-平原地区的159名青年人群的高原脱习服症状评分

目的：对居住在喀喇昆仑山及西藏阿里地区人员进行高原脱习服症状评分调查，为制定有关防治措施提供依据。方法：采用流行病学主观症状问卷调查的方法，对由不同高原地区返回同一平原地区的159名青年人群的18项症状进行调查及症状评分，分析其与居住地海拔高度、人员年龄、居住时间、不同单位、持续或断续居住及文化程度高低的相关性。结果：高原脱习服主观症状评分，海拔5000m以上组明显高于4300m和3700m组，统计学分析均有显著性差异（P〈0．05，P〈0．01）；海拔4300m组与3700m组比较没有统计学差异（P〉0．05）。不同居住人员（不同年龄、职务、单位、文化程度、时间、持续或断续）主观症状评分比较，均有显著性差异（P〈0．01）；持续高原居住组与断续居住组比较也有显著性差异（P〈0．01）。结论：喀喇昆仑山及西藏阿里地区人员返回平原后脱习服主观症状评分与居民年龄、高原暴露时间、居住海拔高度、工作量大小、高原持续暴露成正相关关系。年龄越大、高原暴露时间越长、居住地海拔越高、工作量越大者高原脱习服主观症状评分越高。

The deacclimatization symptom scores of 159 youth returning to the same plain from different plateau

Objective： To analysis deacchmatization symptom scores of 159 youth from Karakoram and Tibet Ali area, and provide the ba- sis for the development of relevant prevention and control measures. Methods： Using the method of epidemiological symptoms questionnaire, 18 symptoms of 190 youth who returned to the plain area from the different plateau were investigated. The symptom scores of different altitude, age, the time of staying, different units, continuous or intermittent stage and education were surveyed. Results： Deacclimatization symptom scores among 5 000 meter groups were significantly higher than those of 4 300 meter and 3 700 meter group （ P 〈 0.05, P 〈 0.01 ）. There was no significant difference between the 4 300 meter group and the 3 700 meter group （ P 〉 0.05）. There were significant differences among the stayed personnel （different age, position, unit, education, time, continuous or intermittent） （P〈 0.01）. There was significant difference between the continuous defended the group and intermittent group （ P 〈 0.01 ）. Conclusion： Deacclimatization symptom scores were related to the plateau exposure time, altitude, workload, plateau continued exposure. The older, the longer exposure, the higher altitude, the greater workload at plateau were showed higher deacclimatization symptom score.
