ObjectiveThis study explored the role of occupational physical activity (OPA), physical demands and psychosocial work-related factors on low back pain (LBP) and neck-shoulder pain (NSP) amongst workers with physically demanding professions.MethodsData from 331 participants within the service and manufacturing sector in the Flemish Employees' Physical Activity (FEPA) study were used, with objective measures of OPA and subjective measures of physical and psychosocial work environment. A modified Nordic questionnaire collected data on LBP and NSP.ResultsLBP (> 30 days over a year) was reported by 25% of participants, NSP (> 30 days over a year) by 30% and the composite measure of LBP/NSP simultaneously by 17%. Objective measures of OPA were not significantly associated with any pain groups. In the final model, self-reported physical demands were associated with NSP (OR 2.03, 95% CI 1.30-3.18) and LBP/NSP (OR 2.00, 95% CI 1.16-3.45) but not LBP. Job control was negatively associated with LBP (OR 0.59, 95% CI 0.35-0.99) and LBP/NSP (OR 0.54, 95% CI 0.3-0.98).ConclusionObjective measures were not associated with LBP or NSP. Self-reported measures provided insights into potential workplace hazards such as physical demands and job control which can be used to inform future strategies to prevent the development of LBP and NSP.© 2021.
