充足的睡眠包含了質與量的雙重要求，睡眠的品質要比睡眠時間更爲重要。本研究以台灣南部某市男性員警爲研究對象，針對該市警局、分局與派出所，共計46家一一造訪，採用匹茲堡睡眠品質指標(PSQI)，嗜睡量表(ESS)及改編之睡眠習慣量表(ASHS)進行問卷調查。總計發出550份，回收187份，有效樣本107份。結果發現員警平均年齡介於35~44歲，平均BMI值爲25.4±3.43，平均年資爲l9.09±5.74年。75.7%的員警睡眠品質較差，睡眠習慣不良與很差的各佔29.0%與7.5%。嗜睡程度屬中度的員警佔44.9%，重度嗜睡佔11.2%。自我評估認爲壓力很大的佔30.8%，最主要的壓力來源是工作(77.2%)，其次爲經濟與生活(20.7%)。和常見定義爲優良睡眠品質、嗜睡程度與適當睡眠習慣之總分相較，男性員警的睡眠品質(t=9.322, p=0.000)、嗜睡程度(t=2.866, p=0.005)與睡眠習慣(t=2.754, p=0.007)均顯著較差。經相關分析發現，員警的嗜睡程度(r=0.273, p<0.01)、睡眠習慣(r=0.228, p<0.05)、精神壓力(r=0.374, p<0.01)與睡眠品質間呈現顯著相關。員警的職務(r=0.203, P<0.05)、執夜勤次數(r=0.216, p<0.05)與高尿酸或痛風(r=0.240, p<0.05)等慢性病亦與睡眠品質間呈現相關。本研究的結論爲我國南部男性員警有肥胖現象，工作壓力過高，睡眠品質甚差，嗜睡程度嚴重，睡眠習慣不良，而睡眠品質與睡眠習慣、工作狀況、嗜睡程度相關，應予以注意議及早改善。

Good sleep includs not only the quantity but also the quality of sleep. The aim of our study was to evaluate the health condition, personal characteristics, shift work, sleep quality, sleepiness and sleep hygiene of male policeman in a Sourthern Taiwan city. The sample was drawn from a metropolitan police forece (46 police institutes, n=550, effective samples=107), and a self-reported questionnaire with Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale (ESS), and revised ASHS was used. The average age of the male policemen was 35~44 years, BMI was 25.46±3.43, average length of service was 19.09+5.74 years. Results showed 75.7% of the male policemen had low sleep quality, 44.9% and 11.2% had moderate and severe sleepiness, respectively. Male policemen with bad and very bad sleep hygiene were 29.0% and 7.5%, respectively. Compared with the global scores defined as good sleeper, normal sleepiness and fair sleep hygiene, the sleep quality (t=9.322, p=0.000), sleepiness (t=2.866, p=0.005) and sleep hygiene (t=2.754, p=0.007) of male policemen were significantly worse. Self-rated high stress level was 30.8%, the main source of stress was from work (77.2%), and the second was life expenses and economics (20.7%). The sleepiness (r=0.273, p<0.01), sleep hygiene (r=0.228, p<0.05) and stress (r=0.374, p<0.01) were significantly associated the sleep quality. The service rank (r=0.203, p<0.05), shift work (r=0.216, p<0.05) and chronic disease, such as gout (r=0.240, p<0.05), of the subjects were also related with sleep quality.
