  ABSTRACT: Low-back pain is a major public health concern because of its socioeconomic burden, especially for chronic forms. The purpose of this study was to analyse the associations between low-back pain and occupational and personal factors, with a special focus on interactions between age and occupational exposures. The study population comprised a sample of 3958 and 4526 working women and men aged 30 to 59 derived from a national health survey (2002-2003 EDS). Low-back pain was assessed using the French version of the Nordic questionnaire. Weight, height and smoking status were obtained through interview at home. Occupational exposures were self-assessed. The associations between low-back pain for more than 30 days in the previous year and occupational and personal factors were assessed using logistic models. An interaction between age and each occupational exposure was studied. In the multivariate models, age was the only personal factor significantly associated with low-back pain for both genders. The other personal factors studied were significantly associated with low-back pain for women only. Handling heavy loads and awkward postures at work were strongly associated with low-back pain for both genders (respectively OR=1.80 [1.46-2.23] and OR=1.65 [1.34-2.03] for men, and OR=1.65 [1.32-2.06] and OR=1.28 [1.04-1.59] for women). A high level of psychological demands at work and a low level of decision latitude were also associated with low-back pain for both genders (respectively OR=1.22 [1.03-1.46] and OR=1.32 [1.11-1.57] for men, and OR=1.31 [1.10-1.56] and OR=1.27 [1.06-1.51] for women). Only the interaction between age and awkward postures for men was borderline significant. This study showed strong associations between occupational exposures and persistent/recurrent low-back pain in a general working population in France. Targeting these exposures in prevention programs could be useful.

  ABSTRACT: To assess the effects of duration of exposure to biomechanical strains on various types of low back pain (LBP). The population study was a random sample from the GAZEL cohort. Durations of exposure to selected biomechanical strains during subjects' working lifetime and potential confounders were assessed in 1996 by self-administered questionnaires. Data on LBP in the previous 12 months were collected in 2001. Relations between various dimensions of LBP and durations of exposure to the biomechanical strains were analysed with multivariate regression models. Polytomous models were built to determine whether some biomechanical strains were specifically associated with some types of LBP. Analyses were performed separately for men (n = 2218) and women (n = 383). Significant associations were observed (ORs reported are those for 20 years of exposure) between LBP and durations of driving and bending/twisting for men (OR 1.24 and 1.37 respectively); LBP for more than 30 days and duration of exposure to bending/twisting for men and women (OR 2.20 and 2.00 respectively) and duration of driving for women (OR 3.15); LBP radiating to the leg and duration of driving for men (OR 1.43) and bending/twisting for women (OR 1.95); LBP radiating below the knee and duration of exposure to pulling/pushing/carrying for men (OR 1.88). Bending/twisting in both men and women, and driving for women appeared to be stronger risk factors for LBP for more than 30 days. Pulling/pushing/carrying heavy loads appeared to be a risk factor specific for LBP radiating below the knee for men. This study suggests that exposure to biomechanical strains has long-term effects and a dose-response relation with duration of exposure and specific effects for some types of LBP.
