Abstract

This study's aim was to analyse the relationship between musculoskeletal disorders (low back pain and dorsalgia) and sociodemographic characteristics, workload and occupational hazards among casual dockworkers. This cross-sectional study addressed casual dockworkers from the state of Rio Grande do Sul, Brazil. The convenience sample was composed of 232 casual dockworkers. Data were collected using a structured interview and observation. Poisson regression analysis was used. Association between low back pain and physiological occupational risk (p = 0.006), total exertion levels (p = 0.014) and frustration (p = 0.020) remained statistically significant, while the use of illicit drugs (p = 0.023), being a quayside worker (p = 0.021) and physiological occupational risk (p = 0.040) remained associated with dorsalgia. Decreasing these variables in the workplace may also reduce the prevalence of musculoskeletal disorders such as low back pain and dorsalgia.

Keywords: casual dockworkers; musculoskeletal disorders; occupational health.
