Abstract Share this page

Fatigue in industrial workers is a multifactorial phenomenon. There are demographic factors that may have a significant influence on the perception of fatigue, but they remain almost unexplored to date.. The present study addresses this issue. A survey to assess fatigue was conducted among CNC lathe operators in three industrial concerns where automotive parts are manufactured. Homokinetic joints in site 1 (121 workers); camshafts in site 2 (121 workers); pistons in site 3 (21 workers). The subjects completed a survey instrument that included two questionnaires to assess fatigue: SOFIíS and OFERíS. There was also a section asking for demographic information. The MANOVA procedure was used to explore the influence of the demographic factors on fatigue. Factors affecting the fatigue dimensions (SOFIíS) were gender, body weight, stature, total length of sleep during a day, and age. Factors affecting the fatigue states (OFER-S) were weight of load being handled, gender, total length of sleep during a day, length of stay in the firm. Non-influential factors were educational status and whether the worker has a second paid job.
