* Significant risk factor for LBP
†Of 1,086 workers data on the occurrence of LBP during follow-up, physical exposure at work and all confounders were available
#Logistic regression adjusted for the confounders: age, gender, exercise behaviour during leisure time, quantitative job demands, decision authority, skill discretion, supervisor support, co-worker support, driving a vehicle during work and leisure time, flexion/rotation of the trunk during leisure time and moving heavy loads during leisure time
CLBL Cumulative low back load
LBP Low back pain
