Occupational biomechanical exposures are considered as risk factors for low back pain in the working population. It has also been suggested that their effects persist after retirement. Our objectives were to assess the role of past biomechanical occupational exposure on low back pain in early old age among male participants of the Gazel Cohort.
Low back pain for more than 30 days in the past 12 months (LBP30) was assessed in 1996 and 2006 using a French version of the Nordic questionnaire in a subsample of the Gazel Cohort. Logistic regression models were used to study associations between LBP30 in 2006 and past occupational biomechanical exposure, self-reported in 1996, taking into account personal and psychosocial work factors self-reported in 1996, and the date of retirement provided by the company. A multinomial model served to study persistent and new cases, according to LBP30 in 1996.
We studied 1,520 men aged 58-67 in 2006, most of them retired. Low back pain for more than 30 days in the past 12 months reported in 2006 was related to occupational biomechanical exposure encountered many years earlier (OR 1.55, 95% CI 1.05-2.27 for 10-20 years of exposure to bending/twisting, OR 1.71, 95% CI 1.17-2.49 for >20 years). These associations appeared specific to low back pain for more than 30 days in the past 12 months which persisted between 1996 and 2006.
These results suggest that occupational biomechanical exposure during active life has persistent effects among men in early old age, even for people who left the workforce. They point out the importance of preventive measures at work for better health later and appear relevant for policy-making decisions concerning age at retirement.
职业生物力学暴露被视为工作人群中腰痛的危险因素。也有人提出，其影响在退休后仍会持续。我们的目标是评估过去的生物力学职业暴露对加泽尔队列男性参与者老年早期腰痛的作用。
1996年和2006年，在加泽尔队列的一个子样本中，使用北欧问卷的法语版本评估过去12个月内持续30天以上的腰痛（LBP30）。采用逻辑回归模型研究2006年的LBP30与1996年自我报告的过去职业生物力学暴露之间的关联，同时考虑1996年自我报告的个人和心理社会工作因素以及公司提供的退休日期。根据1996年的LBP30，使用多项模型研究持续性病例和新发病例。
我们研究了2006年年龄在58 - 67岁之间的1520名男性，其中大多数已退休。2006年报告的过去12个月内持续30天以上的腰痛与多年前遇到的职业生物力学暴露有关（弯腰/扭转暴露10 - 20年的比值比为1.55，95%置信区间为1.05 - 2.27；暴露超过20年的比值比为1.71，95%置信区间为1.17 - 2.49）。这些关联似乎特定于过去12个月内持续30天以上的腰痛，且在1996年至2006年期间持续存在。
这些结果表明，在职期间的职业生物力学暴露对老年早期男性有持续影响，即使是那些已离开劳动力队伍的人。它们指出了工作中预防措施对后期更好健康的重要性，并且似乎与退休年龄的政策决策相关。
