Volume 14, Issue 2 (Iranian Journal of Ergonomics-In Press 2026)
Abstract
Background: Dentistry, as a profession characterized by a static nature, repetitive movements, and occupational stress, is considered a high-risk occupation for the development of musculoskeletal disorders and reduced quality of life. The aim of this research was to investigate the relationship between musculoskeletal disorders and quality of life among dentists.
Methods: This descriptive-analytical cross-sectional study was conducted in 2025 on 150 practicing dentists in the city of Ardabil. Samples were selected using the convenience sampling method. Data were collected using standard questionnaires, including the Nordic Musculoskeletal Questionnaire (NMQ) for musculoskeletal disorders and the World Health Organization Quality of Life (WHOQOL) questionnaire. Data analysis was performed using SPSS 26 software with Chi-square and logistic regression tests.
Results: The most commonly affected areas were the lower back (64.7%), neck (60.7%), and shoulders (52.1%). These problems had led to reduced professional activity in 28.7% of the individuals. Quality of life was at a moderate to low level, with the lowest score belonging to the environmental health domain (56.79 out of 100). A significant association was observed between lower quality of life and increased musculoskeletal complaints in some body areas (p < 0.05).
Conclusion: The results of this study indicate a very high and concerning prevalence of musculoskeletal problems and a moderate quality of life among dentists in Ardabil. Furthermore, the findings emphasize the necessity of implementing comprehensive intervention programs to improve workplace ergonomics and enhance the health and quality of life of dentists.
