ABSTRACT
Background: Studies on the prevalence of work-related musculoskeletal disorders (WRMSDs) among motorcyclists in sub-Saharan Africa are scarce.Objective: This study aimed to investigate the prevalence of WRMSDs and the predisposing factors among commercial motorcyclists operating in Ibadan North Local Government Area, Oyo State, Nigeria.Methods: Information was obtained from 122 (of 200) motorcyclists using a structured questionnaire which elicited information on the respondents' demographic characteristics, work experience, and predisposing factors to, and possible causes of, WRMSDs.Results: The response rate was 61.0%. The age range of the 122 participants was 15 - 55 years. One hundred and thirteen (92.6%) of the motorcyclists reported WRMSDs and 66.4% of all respondents worked for 6 - 10 hours daily. Lower back complaints were most commonly reported. WRMSDs were significantly associated (p < 0.05) with age, marital status, education, years of experience, hours spent at work daily, and days spent working per week. Conclusion: The prevalence of WRMSDs was high among these workers. Age, marital status, educational qualification and work behaviour were risk factors
