摘要：Aim: Low back pain (LBP) has a major impact on work. A lack of prospective data dealing with the diversity of jobs limits the analysis of risk factors for workers. The objective of this study was the prospective modeling of risk of LBP in the salaried workers of the Pays de la Loire region.
Methods: Two successive surveys were conducted in a random sample of salaried workers. The association between individual or occupational risk factors recorded in the first survey and the prevalence of LBP in the second survey was studied, using multi-step logistic regression models. Sensitivity analyses were conducted. The analyses were stratified by sex; only the results related to men are presented.
Results: Among the 3710 participants in the first survey, 2332 responded to the second one, which included 1313 men. The prevalence of LBP was 30% in men. Neck or upper limbs pain, frequent bending or twisting of the trunk and working more than planned were the main risk factors of later LBP. The association observed between a low supervisor support and LBP were no more significant in an analysis restricted to men without prevalent LBP in the first survey.
Conclusion: The role of the biomechanical and organizational factors was higher than the role played by psychosocial factors. The impact of individual factors is tricky to interpret. Some methodological limitations have to be discussed, but the simultaneous analysis of numerous factors in a varied panel of workers has generated an original and useful contribution for prevention actions.
