Work load and work hours in relation to disturbed sleep and fatigue in a large representative sample

Area of Science:

• Occupational Health
• Sleep Science
• Public Health

Background:

• Workplace factors significantly influence employee health.
• Disturbed sleep and fatigue are prevalent issues affecting productivity and quality of life.
• Understanding the interplay between work and health is crucial for preventative strategies.

Purpose of the Study:

• To investigate the relationship between occupational factors and health outcomes.
• To identify specific work-related predictors of disturbed sleep and fatigue.
• To analyze background factors contributing to sleep disturbances and tiredness.

Main Methods:

• A large-scale national survey of 58,115 individuals was conducted over 20 years.
• Data collection involved interviews on work and health status.
• Statistical analysis utilized multiple logistic regression.

Main Results:

• 32.8% of participants reported fatigue, and 12.8% experienced disturbed sleep.
• Significant predictors for disturbed sleep included female gender, age over 49, illness, hectic work, strenuous physical work, and shift work.
• Significant predictors for fatigue included female gender, age under 49, high socioeconomic status, illness, hectic work, overtime, and strenuous physical work.

Conclusions:

• Occupational stress, shift work, and physical workload are key contributors to sleep disruption.
• These work-related factors are strongly associated with increased fatigue levels.
• Findings underscore the need for interventions addressing workplace stressors to improve sleep and reduce fatigue.
