影響婦女夜尿次數的因素

Nocturnal Voids and Associated Factors in Women

夜尿是婦女常見的現象，婦女健康狀態與其夜尿次數息息相關，而少有文獻探究影響夜尿次數的因素。本研究目的是探討睡眠狀況、睡前液體攝取量、疾病史、服藥史、年齡與是否停經等因素，與婦女夜尿次數的關係。本研究採取橫斷式研究設計，以179位至台中某家醫科診所健檢婦女為研究對象，以問卷訪談調查法收集婦女上週每晚平均夜尿次數及影響因素。結果發現婦女的平均年齡是48歲（SD=12.70，範圍 28-81）。其中有144位（81%）的婦女夜尿至少一次、65位（36.5%）至少二次、24位（13.5%）至少三次。logistic多變項迴歸分析結果為，夜尿至少一次（比起0次）的顯著影響因素是淺眠易醒（OR＝6.06）；夜尿至少二次（比起< 二次）的顯著影響因素是淺眠易醒（OR＝3.57）和已停經（OR＝3.00）；而夜尿至少三次（比起< 三次）的顯著影響因素是晚飯後至睡前液體攝取量>500cc （比起≤250cc）（OR＝6.00）和下肢水腫（OR＝4.32）。透過本研究結果，可幫助醫護人員對影響婦女夜尿次數的因素有更深入的瞭解，且能藉此針對影響夜尿次數的因素，給予妥善預防和適當處置。（志為護理, 2008; 7:3, 71-79.）

Nocturia is a very common problem in women. Nocturnal voiding episode is associated with health status in women. To know the factors associated with nocturnal voiding is important for health care providers. However, the available literature on this topic is sparse. Hence, the objective of this study was to assess the relationship between sleep pattern, fl uid intake volume after dinner, medical history, medications, age, years after menopause and nocturnal voiding episodes per night within the last week. We conducted a cross-sectional face-to-face questionnaire interview of 179 women who were participating in a health screening program at a family doctor practice. The results showed that the mean age of the participants was 48 ± 12.70 years (range 28-81) and among them, 144 (81%) reported nocturnal voiding ? 1/night, 65 (36.5%) reported it ? 2/night and 24 (13.5%) reported it ? 3/night. Using multivariate logistic models, the signifi cant independent correlates of having ? 1 nocturnal voids (vs. 0) was poor sleep (OR＝6.06), of having ? 2 nocturnal voids (vs. < 2) were poor sleep and menopause (OR＝3.57 and 3.00, respectively), and of having ? 3 nocturnal voids (vs. < 3) were the fl uid volume drunk after dinner > 500cc vs ? 250cc (OR＝6.00) and leg edema (OR＝4.32). The fi ndings of this study should help health care providers to understand the factors associated with nocturnal voiding in women, allow the provision of appropriate intervention and allow implementation of professional nursing.
