The Occurrence of Carpal Tunnel Syndrome in Frozen Food Factory Employees
冷凍食品加工廠員工腕道症候群研究
摘要
冷凍食品加工廠207位員工依其工作內容分析而歸類成三組，以研究員工腕道症候群之盛行率與危害因素。第一組屬於手部無冷凍品曝露且無反覆性腕部操作者；第二組為手部無冷凍品曝露但具反覆性腕部操作者；第三組則為手部有冷凍品操作曝露且有反 覆性腕部操作者。三組員工經臨床神經學檢查、神經電學檢查及過去病史與作業經歷調查後，結果發現臨床神經學篩選檢查患有腕道症候群者，分別為4.08%、45.94%及47.11%，其中女性盛行率較男性為高。進一步由神經電學檢查證實腕道症候群在第一到第三組之盛行率分別為4.08%、40.54%及37.19%。我們以Mantel-Haenzel方法比較第二及第三組(均為反覆腕部操作者)對第一組，第二組對第一組及第三組對第一組之勝算比(Odds Ratios, ORs)同時校正性別、年齡及工作年資後再比較(adjusted Odds Ratios, aORs)，具反覆腕部操作者發生腕道症候群之機會為對照組之14.39倍，校正後之aORs在第三組均比第二組為高。最後經過邏輯迴歸分析發現性別、冷凍品曝露與否、腕部反覆性操作及後兩者之交互作用等四項與腕道症候群之發生有顯著相關。 本研究發現反覆操作之手腕部運動作業者腕道症候群盛行率偏高，因此，透過正確的健康危害教育認知，早期症狀報告與偵測系統之建立是必須的。

Two hundred and seven (207) active workers from two frozen food plants were classified according to their daily tasks and placed into three groups. Each classification was evaluated for risk factors which could lead to carpal Tunnel Syndrome (CTS). The workers were thoroughly studied by structured interviews, neurological screening, and electrophysiological stud-ies. Those workers who experienced little hands’ local exposure to cold and low repetitive movements of the wrist (group I) served as the internal standard. In groups II (no local exposure to cold, but a high degree of re-petitiveness) and III (a combination of local exposure to cold and a high degree of repetitiveness) 40.54% and 37.19%, of the workers respectively were diagnosed to have CTS by neurological studies. The risk of CTS for group II + III was 14.39 times higher than that of group I, when group I was compared with group II + III (high repetitiveness). After adjusted for sex, age, and/or the length of employment, group III still had a higher risk of CTS than group II. Repetitiveness as well as hands’ local exposure to cold were found to be contributing factors in leading to CTS. Recognition, evaluation, and management of CTS in the related industries in Taiwan should be initiated to assure early diagnosis and prevention of this occupa-tionally related syndrome.
