Abstract
Objectives: Behavioral treatment for nocturia includes wearing compression stockings. However, a reading of the cited literature for evidence shows that there is not enough research data to support this recommendation, and it is controversial. The present study aimed to investigate and supplement evidence on the effects of wearing compression stockings during the daytime in patients with nocturia. Methods: This was a single-arm prospective study to investigate the effects of compression stockings on nocturia for four weeks. Patients were asked to record a frequency-volume chart and complete various questionnaires at baseline and after four weeks, and also provide feedback on treatment satisfaction. The primary endpoint was a change in night-time frequency in the frequency-volume chart from the baseline to the end of treatment. Results: Thirty-four patients (19 men and 15 women; age: 72.3 ± 12.6 years) were included. Two patients dropped out because of pain associated with wearing compression stockings and one due to a refusal to wear compression stockings every day. Therefore 31 patients were analyzed. In the frequency-volume chart, night-time and 24-hour frequencies significantly decreased by 0.5 and 1.1 episodes, respectively (P = 0.004 and P = 0.035, respectively). The hours of undisturbed sleep significantly increased by 0.8 h (P = 0.013). No significant differences were observed in nocturnal or 24-h urine volumes, the number of urgency or urinary incontinence episodes, the mean or maximum voided volume, the nocturnal polyuria index, or the first night-time voided volume. The total overactive bladder symptom score significantly decreased (P = 0.006). Significant reductions were also observed in all overactive bladder symptom score subscores, except for the daytime frequency score. Conclusion: The present results suggest the effectiveness of wearing compression stockings during the day was satisfactory in most patients with nocturia, and the treatment was safely continued in patients who experienced no pain when wearing the stockings. Based on the results of this study, we believe that it is worth considering as a treatment for nocturia.

JMIR Mhealth Uhealth 2022; 10:e34384. [PMID: 35076409 PMCID: PMC8826148 DOI: 10.2196/34384] [Citation(s) in RCA: 41] [Impact Index Per Article: 20.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2021] [Revised: 11/23/2021] [Accepted: 12/17/2021] [Indexed: 12/23/2022] Open
Abstract
Background Wearable devices hold great promise, particularly for data generation for cutting-edge health research, and their demand has risen substantially in recent years. However, there is a shortage of aggregated insights into how wearables have been used in health research. Objective In this review, we aim to broadly overview and categorize the current research conducted with affordable wearable devices for health research. Methods We performed a scoping review to understand the use of affordable, consumer-grade wearables for health research from a population health perspective using the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews) framework. A total of 7499 articles were found in 4 medical databases (PubMed, Ovid, Web of Science, and CINAHL). Studies were eligible if they used noninvasive wearables: worn on the wrist, arm, hip, and chest; measured vital signs; and analyzed the collected data quantitatively. We excluded studies that did not use wearables for outcome assessment and prototype studies, devices that cost >€500 (US $570), or obtrusive smart clothing. Results We included 179 studies using 189 wearable devices covering 10,835,733 participants. Most studies were observational (128/179, 71.5%), conducted in 2020 (56/179, 31.3%) and in North America (94/179, 52.5%), and 93% (10,104,217/10,835,733) of the participants were part of global health studies. The most popular wearables were fitness trackers (86/189, 45.5%) and accelerometer wearables, which primarily measure movement (49/189, 25.9%). Typical measurements included steps (95/179, 53.1%), heart rate (HR; 55/179, 30.7%), and sleep duration (51/179, 28.5%). Other devices measured blood pressure (3/179, 1.7%), skin temperature (3/179, 1.7%), oximetry (3/179, 1.7%), or respiratory rate (2/179, 1.1%). The wearables were mostly worn on the wrist (138/189, 73%) and cost <€200 (US $228; 120/189, 63.5%). The aims and approaches of all 179 studies revealed six prominent uses for wearables, comprising correlations—wearable and other physiological data (40/179, 22.3%), method evaluations (with subgroups; 40/179, 22.3%), population-based research (31/179, 17.3%), experimental outcome assessment (30/179, 16.8%), prognostic forecasting (28/179, 15.6%), and explorative analysis of big data sets (10/179, 5.6%). The most frequent strengths of affordable wearables were validation, accuracy, and clinical certification (104/179, 58.1%). Conclusions Wearables showed an increasingly diverse field of application such as COVID-19 prediction, fertility tracking, heat-related illness, drug effects, and psychological interventions; they also included underrepresented populations, such as individuals with rare diseases. There is a lack of research on wearable devices in low-resource contexts. Fueled by the COVID-19 pandemic, we see a shift toward more large-sized, web-based studies where wearables increased insights into the developing pandemic, including forecasting models and the effects of the pandemic. Some studies have indicated that big data extracted from wearables may potentially transform the understanding of population health dynamics and the ability to forecast health trends.

Sleep 2021; 44:5876847.

Abstract
Study Objectives We examined associations between self-reports about typical sleep patterns and sleep data derived from a wearable device worn on a nightly basis for a prolonged period (mean = 214 nights). We hypothesized that sleep characteristics would correlate better across different methods of assessment (self-report versus wearable) than they would correlate within the same method, a classic psychometric approach (multitrait, multimethod matrix). Methods A cross-national sample of 6,230 adult wearable users completed a brief sleep questionnaire collecting data on sleep duration and number of awakenings (NAW) and provided informed consent to link their responses to data from their wearable watches. The data collection for the wearable occurred over 12 months and the sleep questionnaire was completed subsequent to that. Results Results indicated a large (r = .615) correlation between sleep duration as assessed with the wearable and by self-report. A medium-to-large correlation (r = .406) was also seen for NAW. The multitrait, multimethod matrix suggested minimal method variance, i.e. similar “traits” (sleep duration and NAW) correlated across methods but within a given method, and such “traits” were generally unrelated. Conclusions The results suggest that the longer period of data collection with the wearable generates more stable estimates of sleep than have been reported in most studies of actigraphy. Alternatively, the data might imply that individuals modify their self-reports about sleep via daily feedback to align their perceptions to the output of the wearable.

Abstract
AIMS Nocturia, due to nocturnal polyuria and other conditions associated with nocturnal voiding, affects sleep quality and daytime quality of life (QOL). We aimed to investigate the relationship among nocturia, sleep quality, and daytime QOL in a young Japanese population. METHODS This epidemiological study analyzed data from a retrospective data set containing sleep data from wearable devices worn by 9446 Japanese users and a prospective data set containing answers to a 10-item questionnaire completed by a subset of 605 users in the retrospective dataset. We recorded the first uninterrupted sleep period (FUSP), total sleep time (TST), number of nocturnal voids, sleep quality, daytime QOL, bothering nocturnal voids, and early wake-ups in the morning. RESULTS The subjects were 18-65 years old. The mean TST was 6.7 ± 0.9 h, and the mean number of wake-ups was 2.11 ± 1.1. FUSP and TST decreased (from 334 ± 114 to 173 ± 74 min and 5.9 ± 1.0 to 5.5 ± 1.0 h, respectively) with an increasing number of nocturnal voids, and the change was statistically significant. Logistic regression analysis showed a statistically significant relationship between nocturia and FUSP and the number of wake-ups. CONCLUSION Nocturia has close relationships with FUSP and the number of wake-ups and can result in decreased daytime QOL in young Japanese people.

Abstract
INTRODUCTION Nocturia is a highly prevalent and bothersome medical condition characterised mainly by the need to wake up to pass urine during the main sleep period. Using data from wearable devices, it is possible to examine the sleep of large cohorts in natural settings. This study seeks to use data from connected smartwatches combined with a one-time survey to explore the presence of nocturia and associated level of bother and sleep characteristics in a non-patient cohort of wearable device users representing a broad age range. METHODS The data used come from a retrospective dataset containing sleep data from Withings watches of 250 000 users and a prospective dataset containing answers to a 10-item questionnaire completed by a subset of users in the retrospective dataset. RESULTS The prospective dataset contained 6230 users. Overall, 6.0%, 15.3% and 38.9% of users in the age groups 18-44 years, 45-64 years and 65-90 years, respectively, reported 2 or more nocturnal voids as their customary voiding pattern, corresponding to levels of nocturia consistent with previous literature. The level of bother associated with nocturia was higher among younger users with 27.8% of users aged 18-44 years reporting that their daytime activity was highly affected versus just 14.1% among those aged 65-90 years. A higher number of reported voids per night was associated with watch-derived measures of a lower sleep efficiency, a longer awake duration at night and a shorter first uninterrupted sleep period. CONCLUSION This study suggests not only that nocturia is present among the younger population but also that the younger are more bothered by this medical condition. Using data from wearables it was possible to establish that there is an association between the number of nocturnal voids and sleep characteristics.
