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 6 Logistic regression analysis for work-related LBP and 2 Ergonomic risk-factors (‘Repetitive hand or arm movements’ and ‘Dragging, pushing, or moving heavy objects’)

	Work-related LBP
Ergonomic risk exposure	Crude	Adjusted^a
Little exposure to both ‘repetitive hand or arm movements’ and ‘dragging, pushing, or moving heavy objects’ (n = 17,547)	Reference	Reference
Usually exposed to ‘repetitive hand or arm movements’ (n = 15,192)	2.00 (1.88–2.14)*	1.25 (1.15–1.34)*
Usually exposed to ‘dragging, pushing, or moving heavy objects’ (n = 1798)	2.21 (1.95–2.52)*	1.37 (1.19–1.57)*
High exposure to both ‘repetitive hand or arm movements’ and ‘dragging, pushing, or moving heavy objects’ (n = 6215)	2.70 (2.50–2.92)*	1.49 (1.39–1.59)**
