目的探讨进藏列车乘务人员返回平原后高原脱习服水平及其影响因素。方法选择北京、上海籍进藏列车乘务人员101人,通过问卷调查高原出乘6年多期间高原脱习服表现、高原习服表现、总习服水平的主观认知,并作不同车队间的比较、相关分析。结果全组在出乘后返回平原工休期间的高原脱习服症状检出率为100.00%,主要表现有29项,各项症状的检出率1.96%~86.44%不等;舒张期血压≥90 mm Hg者检出率为16.83%,伴有不同程度的高原反应检出率;认为出乘高原列车以来健康水平总体明显差于原平原工作时者占91.67%,突出表现在:记忆减退86.67%、精力下降78.33%、体力下降73.33%、脑力减退71.67%、睡眠障碍65.00%%、体重增加41.67%、性功能减退30.00%、食欲减退28.33%、月经紊乱26.67%,且上海车队较北京车队有显著的高检出率(P<0.05或P<0.01),与车队(地区、海拔)、出乘总时间、性别、年龄、体重、舒张压呈中-轻度相关(P<0.05或P<0.01)。结论具有“极大跨度、频繁往返、间歇低氧”作业的平原-高原列车乘务人员,依然存在显著的高原脱习服表现;高原脱习服与多种因素相关,高原脱习服与高原习服不良一起对健康构成危害,需高度重视与积极防护。 Objective To explore the level of off-service uniforms and its influencing factors after the crew members of Tibet-Tibet trains returned to the plain. Methods A total of 101 flight attendants in Beijing and Shanghai were enrolled in this study. Subjective knowledge of the performance of plateau uniforms, the performance of plateau suits and the overall service level were obtained through questionnaire survey over the plateau for more than 6 years. Comparison, correlation analysis. Results The rate of outbreak symptom in the plateau returning to the plain during the week was 100.00%, the main manifestations were 29, the detection rates of various symptoms ranged from 1.96% to 86.44%; the diastolic blood pressure was ≥90 mm Hg was detected 16.83%, with varying degrees of detection rate of the plateau reaction; that the health level since the plateau train significantly worse than the original plain work accounted for 91.67%, highlighted in: memory loss of 86.67% , Energy decreased by 78.33%, physical strength decreased by 73.33%, mental retardation 71.67%, sleep disorders 65.00 %%, weight gain 41.67%, sexual dysfunction 30.00%, loss of appetite 28.33%, menstrual disorders 26.67%, and the Shanghai team than the Beijing team (P <0.05 or P <0.01), and had a moderate to mild correlation with fleet (region, altitude), total time, sex, age, body weight and diastolic blood pressure (P < 0.01). Conclusions There are still significant plateau abacus performance in the plateau-plateau train crew with “great span, frequent round-trip and intermittent hypoxia” operation. The plateau uniforms are related to many factors, High altitude unhealthy habits together constitute a hazard to health, we need to attach great importance to and active protection.
