DESCRIPTION: Occupationally, related low back disorders (LBDs) represent a major occupational health concern. The etiology of this health problem is complex and poorly understood. The proposed study investigates the role of biomechanical job demands and psycho social work characteristics in increasing LBD risk among employees in manual materials handling jobs. Although there is a wealth of knowledge associated with each of these categories of risk factors, there is a dearth of studies that have rigorously investigated both categories of risk factors in the same work environment. Therefore, it is difficult to estimate the contribution of each of these risk categories to the overall risk for occupationally-related LBDs. We hypothesize that both types of risk factors make independent contributions to the risk of LBDs, and that psycho social work characteristics are more likely to increase risk for LBD when biomechanical job demands are moderate to low than when they are high. The proposed study uses a prospective cohort design. It significantly increases the standard of scientific rigor of investigations in this area through: (1) reliable, valid state-of-the art measures of both psycho social work characteristics and biomechanical job demands; (2) assessments of exposure variables at multiple points in time; (3) the use of an array of outcome measures for LBD including a validated, highly quantifiable clinical assessment of low back functional status; and (4) adequate power to formally assess both additive and potential interactive effects of the two categories of risk factors. With adequate quantification of exposures, we will be able to accurately estimate the extent to which exposures (both psycho social and biomechanical) need to be decreased to reduce LBP risk. We will also be able to discern when and under what conditions an intervention to improve the psycho social work environment will be likely to reduce LBP and its associated morbidity.

描述： 在职业上，相关的下背部疾病（LBD）代表主要 职业健康问题。 这个健康问题的病因很复杂 并且理解很差。 拟议的研究调查了 生物力学工作需求和心理社会工作特征增加 LBD在手动材料处理工作中的员工风险。 虽然有 与这些风险类别相关的大量知识 因素，缺乏研究对两者进行了严格研究 在同一工作环境中的风险因素类别。 因此，是 难以估计这些风险类别中的每一种对 与职业相关的LBD的总体风险。 我们假设两种类型的风险因素都可以独立贡献 出于LBD的风险，心理社会工作特征更多 当生物力学工作需求中等时，可能会增加LBD的风险 低于它们高。 拟议的研究使用了前瞻性队列设计。 它很大程度上 提高了该领域的科学严格严格标准 通过：（1）可靠的，有效的，最先进的精神衡量标准 工作特征和生物力学工作需求； （2）评估 多个时间点的曝光变量； （3）使用 LBD的结果指标，包括经过验证的高度量化临床 评估下背部功能状态； （4）足够的力量正式 评估这两类的添加剂和潜在的交互作用 风险因素。 通过足够的暴露量化，我们将能够 为了准确估计暴露的程度（心理社会和 生物力学）需要减少以降低LBP风险。 我们还将能够 辨别何时和在什么条件下进行干预以改善 心理社会工作环境可能会减少LBP及其相关的LBP 发病率。
