Abstract

Abstract Background:Work-related musculoskeletal disorders most commonly contribute to years lived with disability among workers. Heavy physical work, static work posture, awkward posture, force exertion, lifting and repetitive movements increase risk of developing work-related musculoskeletal disorders.

Methods and materials: The study used a cross-sectional analytical design.108 non-academic workers at University of Zimbabwe Faculty of Medicine and Health Sciences were sampled through stratified proportional convenient sampling. An adapted Nordic Musculoskeletal Questionnaire capturing socio-demographics and ergonomic risk factors was used to gather data. SPSS v24 was used for data analysis. Results:100 non-academic workers from University of Zimbabwe Faculty of Medicine and Health Sciencesresponded. The 3-month and 12-month prevalence of work-related musculoskeletal disorders were highest in lower back (72% and 75%) and wrists/hands (60% and 69%) respectively. Sociodemographic factors such as age, gender, work experience, educational level and worker category were associated with work-related musculoskeletal disorders.
