目標：本研究主旨在探討臺灣北區盒餐業員工肌肉骨骼不適現況，及其與工作內容之相關性。方法：利用橫斷性研究從受訪者基本資料、生活習慣與盒餐業工作特性探討分析各種可能之危險因子。於西元2002至2003年以結構式問卷針對臺北縣市盒餐業20家計完成309人樣本。結果：盒餐業員工常常使用雙手工作(55.0%)，受訪者多從事搬運物品(61.2%)、裝配餐盒(56.3%)及清潔餐具(52.1%)等工作。大多數員工常使用手推車(62.5%)，且經常站立(88.7%)。在工作類型與身體不適部位中，發現「裝配餐盒」動作與「上手臂」及「腳踝及足」不適症狀、「搬運物品」動作與「前手臂」不適症狀、「清洗食材」動作與「下背及腰」不適症狀之間有顯著的正相關性(p＜0.05)。工作時以「搬抬重物一分鐘以上」的動作對身體12個部位的影響較大(p＜0.01)，其中又以「上背」(OR＝16.9)與「小腿」(OR＝14.4)最為明顯。「伸手過肩的動作」、「使用不自然姿勢(扭身)」及「搬抬重物一分鐘以上」等動作與「肩膀」不適的相關性最顯著。結論：本研究發現由於工作姿勢與型態不同，肌肉骨骼不適的身體部位亦因此而異，搬抬重物與上背或小腿的相關性最明顯。

　　　　　Objectives: To investigate work-related musculoskeletal discomfort (WMSD) and its association with tasks carried out by commissary foodservice employees in northern Taiwan. Methods: A cross-sectional survey of a convenient sample of 309 commissary employees was conducted at 20 factories from 2002-2003 to collect information on individual's demographic characteristics, work characteristics, and perceived discomfort from work. Results: The study participants frequently used both hands (55.0%) while working. The tasks for most study participants included moving objects (61.2%), packing lunch boxes (56.3%), and cleaning dishes (52.1%). Most study participants used trolleys (62.5%) and spent a lot of time standing (88.7%). Results showed significant WMSD was found from the tasks of packing lunch boxes using the upper arm or the ankle/feet, moving objects using the forearm, and washing materials using the lower back and waist. Carrying heavy objects for more than 1 minute for each task was associated with an increased risk of 12 body site-specific WMSD, especially for the upper back (OR=16.9) and feet (OR=14.4). Shoulder pain was significantly associated with awkward postures including lifting the hand over the shoulder, twisting the body trunk, and carrying heavy objects for more than 1 minute. Conclusion: Different postures at work may lead to different body site-specific WMSD. Carrying heavy materials was found to be associated with an elevated risk of discomfort in the upper back and feet.
