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

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’)

	Work-related LBP
Ergonomic risk exposure	Crude	Adjusted^a
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)*
