老年人睡眠品質與身體質量指數相關性之探討

Relationship Between Sleep Quality and Body Mass Index in Elderly Persons

探討老年人其睡眠狀況與身體質量指數之相 關性。 ݲП 本研究採橫斷式研究設計，以立意取樣進行抽 樣，研究對象為南部某高齡醫學中心神經內科及 身心科門診60歲（含）以上之門診病患共397位。 以結構式問卷收集資料。問卷內容包含：人口學 特質、生活型態與睡眠品質評量表等。資料統計 採SPSS 22.0中文版統計軟體進行分析，以描述性統 計分析研究對象之基本屬性及睡眠品質等，另以獨 立樣本t檢定、單因子變異數分析及迴歸進行推論統 計分析。 ݎ๖ 有63％研究對象的睡眠品質是差的（PSQI>5）。 性別之睡眠品質有顯著差異；且女性長者之睡眠品質較 男性差。睡眠時數低於6小時者之BMI值顯著高於6-7小 時及7小時以上者，但在女性長者此現象並不顯著。老 年人之整體睡眠品質與身體質量指數有關，睡眠品質越 差，身體質量指數越高。本研究結果顯示年長者之睡眠 品質與性別、睡眠時數、BMI有關。以進入法（Enter） 迴歸分析此模式可解釋睡眠品質總變異量之40.1％（R2 ＝ 0.401）。 ๖፣ 年長者之BMI與睡眠時數呈現負相關，而BMI與睡 眠品質PSQI則呈現正相關，亦即睡眠時數越少，睡眠品 質越差，BMI值越高。（澄清醫護管理雜誌 2020； 16（4）：29-37）
