Pilot study to examine the impact of shift work on cognitive function in Chinese coal mine workers.
Shift work is commonly used in modern industries such as the coal industry, and there is growing concern over the impact that shift work has on miners' work performance and personal well-being.
A total of 54 miners working three shifts (17 in morning shift, 18 in afternoon, and 19 in night shift) participated in this exploratory study. A resting-state fNIRS functional connectivity method was conducted to assess the cognitive ability before and after the work shift.
Results showed significant differences in cognitive ability between before and after the work shifts among the three-shift workers. The brain functional connectivity was reduced ranking as the night, afternoon, and morning shifts. Decreased brain functional connectivity at the end of the working shift was found compared with before in the morning and afternoon shifts. Opposite results were obtained during the night shift. The resting-state functional brain networks in the prefrontal cortex of all groups exhibited small-world properties. Significant differences in betweenness centrality and nodal local efficiency were found in the prefrontal cortex in the morning and night shifts.
The current findings provide new insights regarding the effect of shift work on the cognitive ability of Chinese coal mine workers from the view of brain science.
研究中国煤矿工人轮班工作对认知功能的影响。
轮班工作在现代工业中很常见，人们越来越关注轮班工作对矿工工作表现和个人福祉的影响。
共有 54 名三班倒工人（早班 17 人、中班 18 人、夜班 19 人）参与了这项探索性研究。采用静息态功能近红外光谱（fNIRS）功能连接方法评估工作前后的认知能力。
结果表明，三班倒工人在工作前后的认知能力存在显著差异。夜班、中班和早班的脑功能连接性降低。与早班和中班相比，工作结束时大脑功能连接性下降。夜班则得到相反的结果。所有组的前额叶皮层静息态功能脑网络均表现出小世界特性。在早班和夜班的前额叶皮层中，介数中心性和节点局部效率存在显著差异。
本研究从脑科学的角度为轮班工作对中国煤矿工人认知能力的影响提供了新的见解。
