Abstract
背景:阻塞型睡眠呼吸中止症(obstructive sleep apnea, OSA)逾三分之一比例的病患係屬於低覺醒閾值表現型(low arousal threshold phenotype,Low ArTH),此類患者會因著較輕微的呼吸阻塞而覺醒,加劇睡眠碎片化(sleep fragmentation)的嚴重度。而目前對於Low ArTH OSA 症狀與病患的體組成特徵之關連性以及相關機轉尚待進一步研究,遂此本文旨就體脂肪、體水分布與呼吸事件期間持續期間、缺氧指數以及睡眠障礙等與疾病症狀的關連進行探討。

方法:回溯性整理新北市雙和醫院睡眠中心2924 位受試者資料,其中含括多項式睡眠生理檢查(polysomnography,PSG)與身體組成量測結果。依據現行Low ArTH OSA 臨床鑑別標準,篩選實驗組(Low ArTH OSA, n=1850)以及對照組 (non-OSA, n=368) 和(Non-low ArTH OSA, n=706)。使用統計分析比較三組各項目之平均值;以回歸模型分析身體組成變項對於PSG 參數與疾病嚴重度之關連性,以及罹患Low ArTH OSA 疾病的風險。

結果:實驗組(Low ArTH OSA)分別在年齡、細胞外液-內液比率項目具有較高的平均值(p<0.01);細胞外液-內液比率之增加與淺呼吸時長呈現顯著線性負相關。在Low ArTH OSA 與non-OSA 兩組之間,經校正年齡、性別、身體質量指數(BMI)後,預測模型發現體脂肪比率、軀幹-四肢脂肪比率以及細胞外液-內液比率三項目與增高罹病風險有顯著關連性,其勝算比[信賴區間](odds ratio, OR[CI])依序為1.58 [1.08-2.3],1.22 [1.04-1.43],1.32 [1.08-1.62];相同校正於Low ArTH OSA 與Non-low ArTH OSA 兩組之間,軀幹-四肢脂肪比率以及細胞外液-內液比率與增高Low ArTH OSA 風險有顯著關連性,其勝算比[信賴區間](odds ratio, OR[CI])分別為1.18[1.05-1.33],1.78 [1.52-2.09]。然而內臟脂肪水平與Low ArTH OSA 罹病風險之間無顯著的證據顯示有關連性。

結論:增加於軀幹處的脂肪以及細胞外液的分布是Low ArTH OSA 疾病之危險因子。
