Low back pain (LBP) in workers is a leading cause of disability and loss of work time, adversely affecting job performance and overall well-being. The primary objective of this study was to evaluate the potential role of effort-reward imbalance (ERI) as a risk factor for the development of LBP among workers.
This analytical cross-sectional study was conducted among industrial workers (n = 1127) in Tehran province. Data were collected using 3 different questionnaires-an occupational-sociodemographic questionnaire, the van Vegchel version of the ERI questionnaire, and the Dutch Musculoskeletal Questionnaire (DMQ). Workers who reported experiencing pain in the past 12 months and the past 7 days were classified as having LBP. To assess the relationship between ERI and other independent factors with LBP, univariate logistic regression was employed. Subsequently, to adjust for the effects of influential factors on the dependent variable, a multiple logistic regression model with backward elimination was utilized.
Out of 1127 participants, 1015 (90.06%) were men. The prevalence of ERI among the participants was 60.69%. The results of the multivariate logistic regression model indicated that having ERI (adjusted odds ratio [AOR], 2.985 [95% CI, 1.994-4.470]; < 0.001), having accident experience (AOR, 3.338 [95% CI, 2.378-4.685]; < 0.001), and being married (AOR, 1.602 [95% CI, 1.028- 2.498]; = 0.037) were associated with an increased risk of LBP among industrial workers.
Similar to findings in other countries and various occupational studies, ERI was prevalent among industrial workers in Iran. Additionally, we found that ERI is a significant risk factor for LBP.
工人的腰痛是导致残疾和工作时间损失的主要原因，对工作表现和整体健康产生不利影响。本研究的主要目的是评估努力-回报失衡（ERI）作为工人腰痛发生风险因素的潜在作用。
本分析性横断面研究在德黑兰省的产业工人（n = 1127）中进行。使用3种不同的问卷收集数据——职业-社会人口学问卷、ERI问卷的范·韦切尔版本以及荷兰肌肉骨骼问卷（DMQ）。报告在过去12个月和过去7天内经历过疼痛的工人被归类为患有腰痛。为评估ERI和其他独立因素与腰痛之间的关系，采用单因素逻辑回归。随后，为调整影响因素对因变量的影响，使用了具有向后排除法的多因素逻辑回归模型。
在1127名参与者中，1015名（90.06%）为男性。参与者中ERI的患病率为60.69%。多因素逻辑回归模型的结果表明，存在ERI（调整后的优势比[AOR]，2.985[95%置信区间，1.994 - 4.470]；P < 0.001）、有事故经历（AOR，3.338[95%置信区间，2.378 - 4.685]；P < 0.001）以及已婚（AOR，1.602[95%置信区间，1.028 - 2.498]；P = 0.037）与产业工人腰痛风险增加相关。
与其他国家和各种职业研究的结果相似，ERI在伊朗的产业工人中普遍存在。此外，我们发现ERI是腰痛的一个重要风险因素。
