Shift work is associated with circadian rhythm disruption that manifests in several aspects related to sleep disorder, including trouble falling asleep, shortened sleep, and daytime fatigue. The objective of this study was to investigate the effects of shift work on sleep and cognitive function in the middle-aged male miners in Kailuan Mining Group. From May 2013 to May 2015, male miners were recruited and enrolled in prospective study. The results of PSQI demonstrated that there were significant differences in the total score, subjective sleep quality and sleep duration between two groups. For subjects with education level of senior middle school or below, our results showed that the scores of BVMT-R and HVLT-R in the day shift group were significantly higher than that in the night shift group. According to PSQI score, further test was conducted for HVLT-R and BVMT-R. For subjects with PSQI score≤5, there were significant differences in HVLT-R scores between two groups. In terms of PSQI score>5, BVMT-R scores in the night shift group were significantly lower than that in the day shift group. The workers for night shift work in adulthood would tend to impaired working memory. Education can also influence the performance of working memory.
