Circadian Rhythm and Health in Heavy Industry Shift Workers
20. juli 2026 opdateret af: Amine Ataç, Istanbul Gedik University
Investigation of Circadian Rhythm, Musculoskeletal Pain, Sleep Quality, and Quality of Life Among Heavy Industry Shift Workers: A Cross-Sectional Study
Shift work can disrupt the body's circadian rhythm, which may negatively affect sleep, musculoskeletal health, and quality of life.
Heavy industry workers who perform rotating or night shifts may be particularly vulnerable to these health problems.
This cross-sectional observational study will evaluate circadian rhythm characteristics, musculoskeletal pain, sleep quality, and quality of life among heavy industry shift workers.
Participants will complete validated questionnaires assessing chronotype, musculoskeletal symptoms, sleep quality, and quality of life.
The study will examine the associations between chronotype and these health outcomes and compare the results across different chronotype groups.
The findings may contribute to a better understanding of the health effects of shift work and support the development of occupational health strategies for shift workers

Morningness-Eveningness Questionnaire (MEQ)
Tidsramme: At enrollment (single assessment)
|
The Morningness-Eveningness Questionnaire (MEQ) is a validated 19-item self-administered questionnaire used to determine an individual's chronotype (morning, intermediate, or evening type).
Total scores range from 16 to 86.
Higher scores indicate a greater preference for morningness, whereas lower scores indicate a greater preference for eveningness.

Cornell Musculoskeletal Discomfort Questionnaire (CMDQ)
Tidsramme: At enrollment (single assessment)
|
The Cornell Musculoskeletal Discomfort Questionnaire (CMDQ) is a validated self-administered questionnaire used to assess the frequency, severity, and work-related impact of musculoskeletal discomfort in different body regions.
The total score is calculated by summing weighted scores across body regions and does not have a fixed minimum or maximum value.
Higher scores indicate greater musculoskeletal discomfort.
