There have been more previous studies on sleep quality and anxiety symptoms among university students in plains areas. However, fewer studies have been conducted on Tibetan university students at high altitude. Analyzing the relationship between sleep quality and anxiety symptoms due to increased altitude may provide a reference for mental health promotion and intervention for Tibetan university students in high altitude areas.
Stratified whole cluster sampling was used. The pittsburgh sleep quality index (PSQI) scale was used to investigate the sleep quality of 4,777 university students at high altitude in China. The self-rating anxiety scale (SAS) was used to investigate anxiety symptoms. The chi-square test was used to compare the detection rates of anxiety symptoms among different groups, and logistic regression analysis was used to analyze the association between sleep quality and anxiety symptoms.
The prevalence of anxiety symptoms among Tibetan university students at high altitude in China was 25.7%. The detection rate of anxiety symptoms among girls (28.4%) was higher than that of boys (22.1%), and the difference was statistically significant ( = 24.634, < 0.001). The detection rates of anxiety symptoms among university students with sleep quality of "Good," "Medium" and "Poor" were 1.8, 4.8 and 39.2%, respectively, and the differences were statistically significant ( = 779.759, < 0.001). Logistic regression analysis after adjusting for relevant covariates showed that the risk of anxiety symptoms was higher in the "Medium" (OR:3.479, 95%CI:1.946 ~ 6.221) and "Poor" (OR:44.817, 95%CI:29.175 ~ 68.847) groups, compared with the "Good" group. The same trend was observed in both men and women at the university level.
There is a close relationship between sleep quality and the occurrence of anxiety symptoms among Tibetan university students at high altitude in China. Improving sleep quality may have a positive effect on reducing the occurrence of anxiety symptoms among Tibetan university students at high altitude.
以往针对平原地区大学生睡眠质量和焦虑症状的研究较多。然而，针对高海拔地区藏族大学生的相关研究较少。分析海拔升高导致的睡眠质量与焦虑症状之间的关系，可为高海拔地区藏族大学生的心理健康促进和干预提供参考。
采用分层整群抽样。运用匹兹堡睡眠质量指数（PSQI）量表对我国4777名高海拔地区大学生的睡眠质量进行调查。采用自评焦虑量表（SAS）调查焦虑症状。运用卡方检验比较不同组间焦虑症状检出率，采用logistic回归分析睡眠质量与焦虑症状之间的关联。
我国高海拔地区藏族大学生焦虑症状患病率为25.7%。女生焦虑症状检出率（28.4%）高于男生（22.1%），差异有统计学意义（χ² = 24.634，P < 0.001）。睡眠质量为“好”“中”“差”的大学生焦虑症状检出率分别为1.8%、4.8%和39.2%，差异有统计学意义（χ² = 779.759，P < 0.001）。调整相关协变量后的logistic回归分析显示，与“好”组相比，“中”组（OR：3.479，95%CI：1.946～6.221）和“差”组（OR：44.817，95%CI：29.175～68.847）焦虑症状风险更高。大学层面的男女生均呈现相同趋势。
我国高海拔地区藏族大学生睡眠质量与焦虑症状的发生密切相关。改善睡眠质量可能对降低高海拔地区藏族大学生焦虑症状的发生有积极作用。
