Table 4 Logistic regression analysis for work-related LBP and 2 Ergonomic risk-factors (‘Fatigue-inducing or painful posture’ and ‘Dragging, pushing, or moving heavy objects’)

From: Relationship between simultaneous exposure to ergonomic risk factors and work-related lower back pain: a cross-sectional study based on the fourth Korean working conditions survey

  Work-related LBP
Ergonomic risk exposure Crude Adjusteda
Little exposure to both ‘fatigue-inducing or painful posture’ and ‘dragging, pushing, or moving heavy objects’ (n = 24,819) Reference Reference
Usually exposed to ‘fatigue-inducing or painful posture’ (n = 7920) 3.01 (2.82–3.22)* 2.17 (2.02–2.34)*
Usually exposed to ‘dragging, pushing, or moving heavy objects’ (n = 2769) 1.72 (1.54–1.92)* 1.33 (1.19–1.50)*
High exposure to both ‘fatigue-inducing or painful posture’ and ‘dragging, pushing, or moving heavy objects’ (n = 5244) 3.04 (2.82–3.28)* 2.00 (1.82–2.20)*
