Introduction: Prevalence of musculoskeletal disorders (MSDs) is high among office workers. One of the most important risk factors of these disorders is awkward posture and inappropriate environmental conditions. So, this study was carried out to determine frequency of MSDS and its related risk factors among the office workers of Minab city healthcare centers in 2018.

Materials and Methods: This cross-sectional study was conducted on 104 staff in Minab city health care centers. Nordic musculoskeletal disorders questionnaire was applied to determine the prevalence of MSDs and Rapid Office Strain Assessment (ROSA) method was used for posture analysis. The data were analyzed by SPSS version 21 using descriptive statistics and chi-square test. Excel software was used to plot the graph.

Results: The highest prevalence rates of MSDs were reported in low back (63.5%), neck (51.9%) and upper back (50%). There was no significant difference between MSDs and age, sex and BMI (P˃0.05) but there was a significant relationship with work experience (P˂0.05). Totally, 36.6% of employees were placed in the first priority of corrective actions (i.e. the need for ergonomic interventions as soon as possible). There was a significant correlation between awkward posture and neck pain (P <0.05).

Conclusion: The frequency of MSDS in health center office workers was high and neck pain was related to awkward posture.
