目的(I)构建和评估机械和心理社会工作暴露的性别相关工作暴露矩阵(JEM)，并检验其对腰痛的预测效度。我们根据挪威版的国际标准职业分类(ISCO-88)对职业进行了4位数的分类。机械和心理社会暴露信息是通过个人电话采访收集的，其中包括已知的腰痛危险因素暴露。我们评估了基于个体和基于JEM的暴露估计值之间的一致性，包括kappa、灵敏度和特异度。我们通过测试腰痛与基于个人和基于JEM的暴露之间的关联来评估JEM的预测有效性。结果显示，构建的JEM和个人工作暴露之间总体上是中等到中等的一致性。与心理社会工作暴露相比，JEM在机械工作暴露方面的表现要好得多。机械JEM和心理社会JEM的预测效度一直较低，但重复性较好。结论机械估计和心理社会应激源，如心理需求、单调的工作和决策自由度，可能在大规模流行病学登记研究中有用。该矩阵的预测效度被评估为总体可接受；因此，它可以成为一种有效和通用的方法来估计工作暴露和下腰痛之间的关系。
Objectives The aim of this study was to (i) construct and evaluate a gender-specific job exposure matrix (JEM) for mechanical and psychosocial work exposures and (ii) test its predictive validity for low-back pain.Methods We utilized data from the Norwegian nationwide Survey of Living Conditions on work environment in 2006 and 2009. We classified occupations on a 4-digit level based on the Norwegian version of the International Standard Classification of Occupations (ISCO-88). The mechanical and psychosocial exposure information was collected by personal telephone interviews and included exposures that were known risk factors for low-back pain. We evaluated the agreement between the individual- and JEM-based exposure estimates, with kappa, sensitivity and specificity measures. We assessed the JEM's predictive validity by testing the associations between low-back pain and the individual- and JEM-based exposure.Results The results showed an overall fair-to-moderate agreement between the constructed JEM and individual work exposures. The JEM performed considerably better for mechanical work exposures compared with psychosocial work exposures. The predictive validity of the mechanical and psychosocial JEM showed a consistently lower but predominantly reproducible association with low-back pain for both genders.Conclusions The mechanical estimates and psychosocial stressors, such as psychological demands, monotonous work and decision latitude in the constructed JEM, may be useful in large epidemiological register studies. The predictive validity of the matrix was evaluated as being overall acceptable;it can thus be an effective and versatile approach to estimate the relationship between work exposures and low-back pain.
