As part of the cross-sectional component of the Semiconductor Health Study, we assessed prevalence of specific musculoskeletal symptoms and their association with possible ergonomic risk factors. A total of 3,175 persons (78% participation rate) from eight manufacturing sites across the U.S. completed a health and work questionnaire. Using logistic regression methods to adjust for nonoccupational factors, we compared musculoskeletal symptom (self report) prevalence among fabrication room (fab) and nonfab workers, among specific work process groups, and among workers exposed to selected ergonomic stressors. Overall, seven of 12 musculoskeletal outcomes were significantly more prevalent among fab workers. Distal upper-extremity symptoms were more common among fab than nonfab workers [relative risk (RR) = 1.44, 95% confidence interval (CI) = 1.26-1.63] and showed a dose-response effect with hours per day spent in the fab; increased risk was associated with frequency of lifting and with use of vacuum wands and projection aligners. Female sex and high somatization index score were associated with increased reporting for all musculoskeletal outcomes.
作为半导体健康研究横断面部分的内容，我们评估了特定肌肉骨骼症状的患病率及其与可能的工效学风险因素的关联。来自美国八个制造场所的总共3175人（参与率78%）完成了一份健康与工作调查问卷。我们使用逻辑回归方法对非职业因素进行调整，比较了制造车间（fab）工人和非fab工人、特定工作流程组工人以及接触选定工效学压力源的工人之间肌肉骨骼症状（自我报告）的患病率。总体而言，12项肌肉骨骼结果中有7项在fab工人中明显更为普遍。远端上肢症状在fab工人中比非fab工人更常见[相对风险（RR）=1.44，95%置信区间（CI）=1.26 - 1.63]，并且与在fab车间每天花费的小时数呈现剂量反应效应；风险增加与举重频率以及使用真空棒和投影对准仪有关。女性性别和高躯体化指数得分与所有肌肉骨骼结果的报告增加有关。
