SLEEP QUALITY AND EXCESSIVE DAYTIME SLEEPINESS IN WOMEN WITH URINARY INCONTINENCE
Urinary incontinence is defined as any complaint of involuntary loss of urine. One of the main symptoms in women with urinary incontinence is nocturia, characterized by the need to awake one or more times per night to void. Repeated nocturnal voiding can leads to chronically disturbed sleep, which negatively affects the sleep quality (SQ). The sleep fragmentation causes excessive daytime sleepiness (EDS), a difficulty to maintain wakefulness or alertness at appropriate situations during the day. The gold standard to measure sleep objectively is polysomnography, however, wrist actigraphy supports large-scale, is cheaper, and can be useful to investigate sleep/wake patterns for prolonged observations in non-laboratory environments.
Therefore, the aim of the present study was to evaluate sleep quality and excessive daytime sleepiness in women with urinary incontinence.
We evaluated 66 women with urinary incontinence. They used the Fitbit Charge 3, an activity tracker, for 7 days to objectively evaluate the SQ and Epworth sleepiness scale to assess EDS.
The patients were aged: 57.7 ± 11.2 years, body mass index (BMI): 29.1± 4.2kg/m2, 59% had mixed urinary incontinence (n = 39), 28% stress urinary incontinence (n = 19) and 12% (n = 08) urge urinary incontinence. According to actigraphy data: total sleep time (TTS): 6.10±0.95 hours; Total time in bed (TTB): 7.0±1.0 hours; Awakening episode per night (WE): 19.1±6.7 events; Awakenings after sleep onset (WASO): 0.88±0.16 hours and sleep efficiency (SE): 87.4±2.3%. The total score for the Epworth sleepiness scale was 11.1 ± 6.2, characterizing the presence of EDS.
According to the results, despite the presence of EDS and shortened sleep time, it was showed that the women with urinary incontinence had good sleep efficiency. Future research is suggested to correlate sleep data obtained with actigraphy with those obtained by polysomnography in women with urinary incontinence, since there are evidences indicating overestimation of sleep efficiency by the actigraphy.
