目的：進行本國某工廠員工睡眠品質與睡眠障礙的流行病學調查，並探討肥胖與年齡對睡眠呼吸障礙的影響。材料與方法：研究對象為台灣某工廠員工，以前瞻性、隨機取樣的方法由14,725 名員工中隨機取樣731 人(4.96%) 發放匹茲堡睡眠品質量表(Pittsburg Sleep Quality Index, PSQI)、嗜睡問卷(Epworth Sleepiness Scale, ESS) 以及打鼾問卷(Snore Outcomes Survey, SOS)，由受訪者自行填答。以卡方檢定(Chi-square)、史匹曼相關係數(Spearman correlation coefficient)、與one-way ANOVA 探討身體質量指數與年齡對睡眠呼吸障礙的影響。結果：回收問卷501 份，回收率68.5%。受訪者平均年紀為46.1 ± 7.7 歲，男性佔92.1% (668 人)。嚴重打鼾發生率為8.8% (44 人)，嚴重嗜睡發生率為8.5% (43 人)。身體質量指數與打鼾程度呈顯著相關(r = -0.1488, p =0.0008)；打鼾分布情形在身體質量指數不同的族群中有顯著差異(p < 0.05)。年齡與打鼾程度有顯著相關(r = -0.1468, p = 0.0010)；打鼾嚴重度在各年齡組群中分布確實有所差異(p < 0.05)。結論：台灣中年男性中，以問卷調查結果推估罹患睡眠呼吸障礙盛行率不低，其臨床表現以打鼾程度加重較為明顯，身體質量指數與年齡分佈和打鼾程度呈明顯相關。建議以中年男性人口為主的工廠應將阻塞性睡眠呼吸中止症的篩檢納入工安的重點工作項目，並將有睡眠呼吸障礙的員工進一步予以隔夜多頻道睡眠檢查(polysomnography, 簡稱PSG)，以篩檢出罹患阻塞性睡眠呼吸中止症的員工，降低職災發生率。

Objectives: This domestic prevalence study explores the impacts of bodymass index (BMI)and age on sleep-disordered breathing (SDB) . Materials and Methods: The Pittsburgh SleepQuality Index (PSQI) , Epworth Sleepiness Scale (ESS) , and Snore Outcomes Survey (SOS)wereself-administered randomly to 731 (4.96% of 14,725) employees at a chemical factory in aprospective manner. Chi-square test, Spearman correlation coefficient, and one-way analysis ofvariance (ANOVA) were used to investigate the impacts of BMI and age. Results: Thequestionnaire return rate was 68.5% (n = 501) . The mean age was 46.1 ± 7.7 years with a malepredominance (n = 668, 92.1%) . Severe snoring was reported by 44 (8.8%) , while severesleepiness was reported by 43 (8.5%) of respondents. The body-mass index (BMI; kg/m2) (r =-0.1488, p = 0.0008) and age (r = -0.1468, p = 0.0010)were significantly associatedwith the severityof snoring (r = -0.1488, p = 0.0008) .Conclusions: The domestic prevalence of sleep disturbancesamong middle-aged civilians might have previously been underestimated. Obesity and older agemay be associated with a more-severe level of snoring, and both are risk factors for obstructivesleep apnea. Prevention of SDB is a priority for improving occupational safety.
