Circadian Rhythm and Health in Heavy Industry Shift Workers

NCT07702344 · Status: RECRUITING · Type: OBSERVATIONAL · Enrollment: 220

Last updated 2026-07-21

No results posted yet for this study

Summary

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
