Work-related musculoskeletal disorders among desludging operators in Uganda

Abstract

Background Despite the limited evidence, desludging operators remain at a heightened risk of work-related musculoskeletal disorders (WMSDs). This study established the prevalence and predictors of WMSDs among desludging operators in Uganda. Methods A digitalized structured questionnaire was used to collect cross-sectional data on musculoskeletal disorders and routine workplace activities from 303 desludging operators in Uganda. Data were analyzed using STATA version 15.0. Results The prevalence of WMSDs among desludging operators was 29.7%. The background characteristics associated with WMSDs included; attending safety training in the last 12 months (APR = 0.55, 95% CI: 0.31–0.98) and undertaking regular health check-ups (APR = 1.68, 95% CI: 1.16–2.44). The ergonomic factors associated with WMSDs were; working with a bent wrist (APR = 2.64, 95%CI: 1.54–4.52), working with hands above the head (APR = 0.40, 95% CI: 0.26–0.62), and pinching unsupported objects (APR = 0.87, 95% CI: 0.59–1.29). Psychosocial factors associated with WMSDs included; neither agreeing nor disagreeing about being able to influence the availability of equipment needed to do their work = 0.43, 95% CI: 0.20–0.94), having much influence over the amount of work done (APR = 1.75, 95% CI: 1.05–2.91), and sometimes feeling that everything done was an effort (APR = 1.71, 95% CI: 1.01–2.89). Conclusion The prevalence of WMSDs was high among desludging operators in Uganda. We recommend providing comprehensive training on occupational health and safety, with a specific focus on ergonomic hazards. In addition, personal protective equipment uses, regular exercise programs, and considerations for work pace, rest, and recovery opportunities should be prioritized to reduce the risk of WMSDs.
