Results In total, 12.8% (861 individuals) reported LBP
during the last month at follow-up. Work-related
psychosocial predictors of LBP were high job demands
(OR 1.41, 95% CI 1.16 to 1.72) and low job control (OR
1.26, 95% CI 1.01 to 1.57). Mechanical factors were
prolonged standing (OR 1.48, 95% CI 1.20 to 1.83),
awkward lifting (OR 1.55, 95% CI 1.28 to 1.88) and
squatting/kneeling (OR 1.29, 95% CI 1.04 to 1.61). The
estimated population risk attributable to these factors was
approximately 42%. The risk for LBP associated with
psychosocial exposure was not influenced by adjustment
for mechanical risk factors, and vice versa. There was no
substantial confounding related to age, gender, education,
occupation or psychological distress.
