Given their high prevalence and negative health and economic impacts, there is an urgent need to identify MSD-related hazards and their contributing factors. The comprehensive risk assessment of MSDs (CRAMUD) technique was used in this study to evaluate the risk of acquiring MSDs and ascertain the point prevalence of these illnesses among workers in Tehran Province who manufacture automobile components.<br> <strong>Methods</strong>: This cross-sectional analytical investigation was conducted in 2024 in an automotive parts manufacturing industry in Tehran Province, Iran. A total of 340 workers were selected from 360 available workers based on the inclusion criteria. The instruments used included the CRAMUD questionnaire, the rapid entire body assessment (REBA) method, and the Cornell musculoskeletal discomfort questionnaire (CMDQ) to measure musculoskeletal discomfort. Data were analyzed using SPSS software (version 27). The Shapiro-Wilk test was used to assess the data&rsquo;s normality. The relationships between all variables were examined using Pearson correlation tests and linear regression analyses. The chi-square test was also used to examine group differences.<br> <strong>Results</strong>: The mean CRAMUD MSD risk score was 11.12&plusmn;3.53, and the point prevalence of MSDs was 44.8%. Additionally, 18.5% of the participants were highly risky, and 26.3% were risky. There was a high positive correlation between CRAMUD, REBA (r=0.755, P<0.001), and CMDQ (r=0.776, P<0.001) scores. Linear regression analysis also showed that physical, personal, and psychosocial items had significant (P<0.05) effects on the CMDQ score.<br> <strong>Conclusion</strong>: The results of this study confirm the significant prevalence of MSDs in the automotive parts manufacturing industry and the high validity of the CRAMUD method in assessing associated risks. The incidence and severity of MSDs can be prevented by implementing preventive interventions and improving ergonomic conditions.</div> Musculoskeletal disorders (MSDs, Comprehensive risk assessment of musculoskeletal disorders (CRAMUD), Point prevalence, Risk assessment, Auto parts manufacturing industry 307 320 http://ptj.uswr.ac.ir/browse.php?a_code=A-10-683-4&slc_lang=en&sid=1 Aboalfazl Komeili abkomeili1998@gmail.com No Safety Promotion and Injury Prevention Research Center, Research Institute for Health Sciences and Environment, Shahid Beheshti University of Medical Sciences, Tehran, Iran.
