This study aimed to quantify the interaction between physical and psychosocial factors on the presence of neck/shoulder symptoms (NSS) and its consequences (reduced activities and absenteeism) among 1294 coal mining workers in Indonesia. A self-administered questionnaire was used to obtain information on current workplace exposure and NSS and its consequences. Participants were grouped into one of four combination exposure groups: low physical and low psychosocial (as the reference group); low physical and high psychosocial; high physical and low psychosocial, and high physical and high psychosocial (HPhyHPsy). The attributable proportion (AP) due to interaction between both factors was examined. Individuals in the HPhyHPsy group were most likely to report NSS [odds ratio (OR) 4.83, 95% confidence interval (CI) 2.43-9.58], reduced activities (OR 3.90, 95% CI 2.36-6.43), and absenteeism (OR 3.91, 95% CI 2.11-7.25). This study has shown an interaction between physical and psychosocial factors that increases the OR of NSS (AP 0.49, 95% CI 0.08-0.89). Practitioner Summary: Although physical and psychosocial factors are known to be predictors for NSS, little is known about their interaction. Self-reported questionnaire was used to obtain information about physical and psychosocial factors at work. This study found an interaction between the physical and psychosocial risk factors that increases the odds ratio of NSS.
本研究旨在量化身体因素与心理社会因素之间的相互作用对印度尼西亚1294名煤矿工人颈部/肩部症状（NSS）的存在及其后果（活动减少和旷工）的影响。采用自填式问卷获取有关当前工作场所暴露情况、NSS及其后果的信息。参与者被分为四个组合暴露组之一：低身体因素和低心理社会因素组（作为参照组）；低身体因素和高心理社会因素组；高身体因素和低心理社会因素组，以及高身体因素和高心理社会因素组（HPhyHPsy）。研究了两种因素之间相互作用导致的归因比例（AP）。HPhyHPsy组的个体最有可能报告NSS[比值比（OR）4.83，95%置信区间（CI）2.43 - 9.58]、活动减少（OR 3.90，95%CI 2.36 - 6.43）和旷工（OR 3.91，95%CI 2.11 - 7.25）。本研究表明身体因素与心理社会因素之间存在相互作用，这增加了NSS的OR值（AP 0.49，95%CI 0.08 - 0.89）。从业者总结：虽然已知身体因素和心理社会因素是NSS的预测因素，但它们之间的相互作用却鲜为人知。采用自填式问卷获取工作中身体因素和心理社会因素的信息。本研究发现身体风险因素与心理社会风险因素之间存在相互作用，这增加了NSS的比值比。
