بررسی شیوع اختلالات اسکلتی-عضلانی و عوامل مؤثر بر آن در کشاورزان شهرستان زرند در سال 1390

Background & objective: Farmers are exposed to numerous risk factors for musculoskeletal disorders, such as awkward postures, highly repetitive movements and carrying heavy loads. The prevalence of these symptoms is therefore predicted to be significant in this group of workers. The present study was conducted to determine the prevalence of musculoskeletal disorders among farmers in Zarand county in Iran. Methods: The present descriptive, analytical, cross-sectional study was conducted on 350 farmers in Zarand. Participants were selected through simple random sampling. Data were collected by community health workers at health houses of the region using the Nordic Questionnaire. The data obtained were then analyzed in SPSS-18. Results: A total of 98% of the farmers were male, 98.9% were married and 62.9% had a normal BMI. The highest prevalence of musculoskeletal disorders was perceived in the knees (58.3) and the lowest in the elbows (8.19) over the last 12 months. The results of statistical tests showed a significant relationship between age and the prevalence of musculoskeletal disorders in all the 9 body parts examined. A significant relationship also existed between the frequency of these disorders and variables including weight and height. Work experience and good exercise habits reduced the likelihood of developing these disorders. Conclusion: The prevalence of musculoskeletal disorders was significant among the farmers examined. Performing ergonomic interventions aimed at modifying body posture at work, designing useful tools and performing exercises at set intervals are measures that should be taken to help farmers keep healthy.
