Prevalence and Associated Factors of Musculoskeletal Disorders Among Porters in Taxi Parks of Kigali, Rwanda: A Cross-Sectional Study

Background:Musculoskeletal disorders (MSDs) are a leading cause of work related disability,particularly in physically demanding occupations within the informal labor sector.Despite their substantial burden, MSDs among informal workers in sub-Saharan Africa remain under-investigated.This study assessed the prevalence and associated risk factors of MSDs among porters working in major taxi parks in Kigali, Rwanda. Methods:A cross-sectional study was conducted among 144 randomly selected porters from Nyabugogo, Remera, and Nyanza taxi parks. Data were collected using a structured questionnaire adapted from the Standardized Nordic Musculoskeletal Questionnaire.Descriptive statistics were used to estimate MSD prevalence, while multivariate logistic regression identified associated factors, expressed as adjusted odds ratios (AORs) with 95% confidence intervals (CIs). Conclusion:MSDs are highly prevalent among Kigalis porters and are significantly influenced by both socio-demographic and occupational factors. These findings highlight an urgent need for targeted ergonomic interventions, occupational health training, and policy reforms focused on informal laborers.
