摘要
目的 探索在不同海拔地区个体记忆功能的变化规律及其影响因素。方法 招募70名志愿者,在1335 m(低海拔)、3681 m(中海拔)、5219 m(高海拔)3个海拔高度利用临床记忆量表开展指向记忆、联想学习、图像自由回忆、无意义图形再认、人像特点联系回忆测验,并对记忆功能的影响因素进行分析。结果 (1)各分测验量表分及记忆商在不同海拔地区之间差异均有统计学意义(P<0.001),其中,低海拔及中海拔地区的量表分和记忆商均显著高于高海拔地区(P<0.05)。(2)不同性别、学历、岗位受试者的记忆商之间存在显著差异(P<0.001)。(3)在不同海拔地区,记忆商与学历、岗位存在显著相关(P<0.001)。结论 高原环境可能会对个体的记忆功能产生显著影响,且随海拔增高影响愈加显著,同时记忆功能可能与学历存在显著相关性。
Objective To investigate the influencing factors and regularity of the working memory at different altitudes. Methods Seventy volunteers were recruited and finished Clinical Memory Scale,involving the pointing memory test,associative learning test,image free recall test,meaningless image recognition test,and portrait feature associative recall test,when exposed to 1335 m(low altitude),3681 m(middle altitude),and 5219 m(high altitude),respectively.The influencing factors of memory function were explored. Results(1)There was statistically significant difference in the scale scores and memory quotients between different altitudes(P<0.001). Among them,the scale score and memory quotient of low and middle altitude areas were significantly higher than those of high altitude areas(P<0.05).(2)There was significant difference in the memory quotient of volunteers of different genders,educational backgrounds and positions(P<0.001).(3)The memory quotient was significantly correlated with levels of education and positions at different altitudes(P<0.001). Conclusion The plateau environment may have a significant effect on individual memory function,and the effect becomes more significant with the increase in altitude. Memory function may be significantly correlated with levels of education.
