Abstract: BACKGROUND:Prevention of Work-Related Musculoskeletal Disorders (WRMSDs) is crucial as they jeopardize the well-being of the workforce in workplaces and are prevalent in developed and developing countries. OBJECTIVE:This study aimed to determine the prevalence of WRMSDs among Iranian workers. METHODS:A systematic review and meta-analysis of WRMSDs in Iran was performed by searching relevant keywords in authentic databases and search engines such as SID, Google Scholar, Medlib and PubMed. Twenty-seven published articles in the field of WRMSDs from 2001 to 2010 were searched. Meta-analysis and random effects approach were used to analyze data. Heterogeneity investigation of articles was done using I2 index. RESULTS:The total sample size was 6,090 workers with a mean of 225 samples per study. The upper and lower back had the highest prevalence rate of self-reported WRMSDs with 38.1% (95% CI: 29.9–46.4), and 50% (95% CI: 42.5–57.5), respectively. Also, knee had the highest prevalence among lower extremity disorders with 42.1% prevalence rate (95% CI:35.1–49.1). CONCLUSIONS:A high prevalence of WRMSDs in upper and lower limbs was reported in Iran. Trainings with regard to occupational ergonomics and industrial hygiene programs were recommended for minimizing the work-related risks of musculoskeletal disorders.
