多數的外籍勞工族群主要負責工廠內較為粗重的工作，所以其是否影響到外籍勞工的健康也引起職業醫學界的關心。工作對健康的影響相當廣泛，而本研究主要是針對夜班工作之外籍勞工的睡眠品質及工作時的精神狀況做調查分析。本研究之對象為南臺灣兩家五金配件生產供應商之160名外籍勞工，以匹茲堡睡眠品質量表及Epworth Sleepiness Scale嗜睡指數量表兩種問卷作分析，實際回收有效問卷共120份。本研究依日班工作及夜班兩種工作時間之外籍勞工進行統計分析，分析結果顯示夜班之外籍勞工的PSQI及ESS score均高於日班工作之外籍勞工。而年齡、婚姻及性別則不影響PSQI，但於ESS score方面則男性外籍勞工高於女性。
