Influence of Lower Urinary Tract Symptoms, Physical Activity, and Depression on the Quality of Sleep in Elderly Women with Urinary Incontinence

ABSTRACT

PURPOSE: This study was to identify factors influencing the quality of sleep in elderly women with urinary incontinence and examine the relationship among the factors. METHODS: The study investigated 113 elderly women with urinary incontinence who were subject to the visiting care program at health centers in D-gu, D-si, South Korea. The collected data were analyzed using IBM SPSS version 19.0 along with χ²-test, t-test, ANOVA, Pearson's correlation, and multiple regression. RESULTS: The total Pittsburgh Sleep Quality Index (PSQI) of the participants was found to be 11.41±4.34. As a result of the correlation analysis, PSQI was found to have significant correlations with Female Lower Urinary Tract Symptoms (BFLUTS) (r=.32, p<.001). The Korean version of Physical Activity Scale for Elderly (K-PASE) was (r=−.34, p<.001) and the Geriatric Depression Scale Short Form (GDS-SF) was (r=.23, p=.012). Multiple regression analysis found sleeping pill use (β=−.35, p<.001) had the strongest influence on PSQI, followed by physical activity (β=−.20, p<.001), depression (β=.20, p<.001), and lower urinary tract symptoms (β=.19, p<.001). The total model explanatory power was 28.3% (F=12.07, p<.001). CONCLUSION: The study findings are expected to be useful for enhanced understanding of the quality of sleep in elderly women with urinary incontinence.
