[Background]Fatigue among distribution network live-line workers in complex operational envi-ronments has become increasingly severe and requires widespread attention. [Objective]To investigate the positive rates of fatigue and associated influencing factors of live-line power distribution workers,and to make a reasonable strategy to reduce the fatigue of front-line workers. [Methods]Power supply companies in Guangdong,Guangxi,and Yunnan provinces were selected by cluster sampling in 2023,and all front-line live-line workers in the selected companies were recruited.The questionnaire used in this study consisted of two parts:one was the Fatigue Scale-14(FS-14)for investigating fatigue status and the other was for associated influencing factors.A FS-14 score greater than 3 points was defined as fatigue.χ2 test and logistic regression were em-χ2 ployed to analyze the factors affecting fatigue. [Results]A total of 1 341 questionnaires were distributed,and 1 217 valid questionnaires were recovered,with a valid response rate of 90.75%.The average fatigue score of the participants was(6.84±3.79)points,and a total of 1 054 participants scored over 3,resulting a fatigue positive rate of 86.6%.The logistic regression model showed that working under extreme weather(OR=2.03,95%CI:1.38,2.98),overtime 2-3 times a week(OR=5.24,95%CI:1.28,21.40),overtime everyday(OR=6.95,95%CI:1.71,28.27),frequent wrist rotation(OR=1.95,95%CI:1.08,3.51),and leaning back slightly(OR=2.94,95%CI:1.19,7.28)associated with higher positive rates of fatigue. [Conclusion]The high positive rate of fatigue among live-line power distribution workers suggests severe fatigue issues.Extreme weather conditions,working overtime frequency,and maintaining wrist rotation and backward bending postures during work are main factors af-fecting their fatigue.
