摘　　要：目的:以焦虑水平、携氧能力、睡眠质量等高原身心关键因素探讨高原环境下短期移居者注意网络的潜在影响机制。方法:对112名在高原生活两年以上的移居者进行了SCL-90问卷、匹兹堡睡眠质量问卷、注意网络测验(ANT)的测试,并采集静脉血分析了血红蛋白浓度,考察高原环境下个体的焦虑水平对注意功能的影响中睡眠质量和携氧能力的中介和调节作用。结果:(1)高焦虑组的注意执行功能网络效率显著低于低焦虑组(t=-3.96,P<0.01);(2)血红蛋白浓度偏高组的睡眠质量显著优于血红蛋白浓度正常组(t=2.31,P<0.01);(3)睡眠质量在焦虑水平和注意执行网络之间存在完全中介作用(t=2.73,P<0.01,95%CI=[0.07,0.45]);(4)血红蛋白浓度在焦虑水平和睡眠质量之间存在调节作用。结论:在高原环境下个体高的携氧能力可以通过调节睡眠质量来降低个体的焦虑水平,进而改善注意网络的执行功能。Objective:To explore the potential mechanisms of the attention network in short-term migrants in high altitude environments,this study examines the key factors such as anxiety levels,oxygen carrying capacity,and sleep quality in the Tibetan Plateau.Methods:The SCL-90 questionnaire,the Pittsburgh Sleep Quality index(PSQI)and the Attention Network Test(ANT)were administered to 112 migrants who had lived at high altitude for two years,and venous blood was collected for hemoglobin concentration analysis.Results:(1)the executive function network efficiency of the high anxiety group was significantly lower than that of the low anxiety group(t=-3.96,P<0.01);(2)The sleep quality of the higher hemoglobin concentration group was significantly better than that of the normal hemoglobin concentration group(t=2.31,P<0.01);(3)Sleep quality has a complete mediating effect between anxiety level and attention executive network(t=2.73,P<0.01,95%CI=[0.07,0.45]);(4)Sleep quality and hemoglobin concentration have mediating effects on anxiety level and attention executive network.Conclusion:High oxygen-carrying capacity of individuals in plateau environment can reduce the anxiety level of individuals by regulating sleep quality,and then improve the executive function of attention network.
