Abstract

This cross-sectional descriptive study aimed to assess ergonomic risks and examine associated factors among 73 computer user support staff working in the Office of the President Building, Suratthani Rajabhat University. Data were collected using a general information questionnaire and the Rapid Office Strain Assessment (ROSA) tool. Descriptive and inferential statistics were applied, including Pearson’s Chi-square test and logistic regression. The results showed that most respondents were female (83.6%), aged 40-49 years (45.2%), obese based on body mass index (49.3%), and physically inactive (61.6%). A vast majority (95.9%) of respondents worked more than eight hours per day, while 43.8% reported working overtime. Additionally, 78.1% used computers, a mouse, and a keyboard for more than six hours daily. According to ROSA scores, 89% were classified as having high to very high ergonomic risk, 11% had moderate risk, and none were in the low-risk category. Common ergonomic risk factors included inappropriate seat cushions (32.9%), absence of lumbar support (31.5%), and lack of hands-free equipment (32.9%). Work experience had statistically significant association with ergonomic risks, those with 4–6 years and 7–10 years of experience had 5.6 and 7.3 times higher risk, respectively, than those with 1–3 years of experience (p < 0.05). These findings highlight a high prevalence of work-related musculoskeletal disorder (WMSD) risks among academic support staff. Workplace ergonomic improvements, promotion of correct work behaviors, and the implementation of occupational health policies are recommended for sustainable risk prevention.
