ABSTRACT
BACKGROUND: Fatigue, sleep disorders, and daytime sleepiness are interconnected, posing significant risks to occupational health and workplace safety. However, the literature on their relationships remains fragmented, with notable gaps, particularly concerning working populations. This descriptive cross-sectional study aimed to evaluate sleep quality (SQ), daily sleep time in hours (DST), daytime sleepiness, fatigue levels among employees in an automotive workplace, and their interrelationships.
METHODS: This study assessed fatigue, DST, SQ, and daytime sleepiness (DTS) among employees aged 21-51 years working under the same conditions. Data were collected using questionnaires and two validated scales: the Check Individual Strength Scale (CIS) for fatigue and the Epworth Sleepiness Scale (ESS) for excessive daytime sleepiness.
RESULTS: None of the Check Individual Strength Scale (CIS), or SQ points, mean values or DST hours values significantly differ due to any sociodemographic independent variables. Epworth Sleepiness Scale (ESS) points mean values differ significantly due to BMI values. However, statistically significant relationships were identified among CIS, ESS, SQ points, and DST hours. Additionally, a positive correlation was observed between ESS and CIS scores. These findings suggest reciprocal effects among fatigue, SQ, DST, and daytime sleepiness.
CONCLUSION: While sleep problems cause fatigue also chronic fatigue syndrome may be the reason of worse SQ. Further research is necessary to emphasize the importance of addressing the interplay between fatigue, excessive daytime sleepiness, SQ, and DST in hours to improve workplace safety and employee well-being.
