Relationship between mental fatigue and cognitive functions in energized line workers of electric sector companies in Aragua State-Venezuela, 2024

Introduction: Understanding the physical and mental state of operational personnel in the electrical sector was essential to ensure health and prevent workplace accidents. This research analyzed the relationship between mental fatigue and cognitive functions in energized line workers of electric companies in Aragua state, Venezuela. Methods: The study was developed under the positivist paradigm with a quantitative approach, non-experimental, descriptive, field-based, and cross-sectional design. The sample consisted of twelve workers assigned to energized line departments. Data collection was conducted through observation, photographic records, sociodemographic survey, Montreal Cognitive Assessment Test version 8.1 (MoCA), and Subjective Fatigue Patterns Test (PSF). Pearson's correlation coefficient was used to analyze the relationship between variables. Results: The results showed a low inverse correlation, suggesting that increased fatigue levels could be associated with a decrease in cognitive function values. Conclusions: A moderately low and non-significant statistical correlation was concluded, suggesting the need for future research with larger sample sizes and validation of other variables such as age, educational level, experience, as well as specific analysis of the Montreal Cognitive Test variables.
