Do sleep problems or urinary incontinence predict falls in elderly women?

Real-World Evidence for Risk Factors of Bruises and Fractures from Falls in Patients with Overactive Bladder: A Medical Record Analysis

Aim

To identify the risk factors for bruises and fractures from falls in patients with overactive bladder (OAB).

Methods

We evaluated 1136 patients with OAB and aged ≥50 years who visited our hospital. Age, sex, frequency of nocturnal urination, and urinary incontinence type were investigated in the 360 eligible patients. Patients were divided into three groups: those patients without falls (no-fall group), those with fall bruises (bruise group), and those with fall fractures (fracture group). The risk factors for bruises and fractures in patients with OAB were evaluated using the logistic regression analysis. In addition, association between the bruises or fractures from falls and the behavior around urination during the night was investigated.

Results

The multivariate logistic regression analysis showed that female sex (odds ratio (OR) 2.888, p = 0.030) and nocturnal urination frequency ≥3 times/night (OR vs. ≤2 times/night, 2.940; p = 0.040) were significantly associated with bruises. Nocturnal urination frequency ≥3 times/night (OR vs. ≤2 times/night, 2.835; p = 0.026) and urge incontinence (OR 3.415, p = 0.016) were significantly associated with fractures. Behavior around urination during the night was significantly associated with fractures (p = 0.009).

Conclusion

In the real-world clinical setting, increasing nocturnal urination frequency is a common risk factor for bruises and fractures. Also, female sex and urge incontinence were the risk factors for bruises and fractures, respectively. OAB patients with urge incontinence would especially require aggressive intervention to prevent fractures during night-time voiding.

Observed daytime sleepiness in in-hospital geriatric patients and risk of falls

BACKGROUND

Daytime sleepiness and falls are frequent in geriatric in-hospital patients; however, the relationship between both events is not clear. To test the hypothesis that observed daytime sleepiness is associated with falls in geriatric in-hospital patients data collected from medical records of patients who were admitted to an acute geriatric department were retrospectively analyzed.

METHODS

The data from the medical records of patients who were admitted to the geriatric department of the Alfried-Krupp-Hospital in Essen, Germany in the period from January 2018 to March 2020 were retrospectively analyzed. Personal data, data concerning the geriatric assessment, observed daytime sleepiness, and falls were recorded.

RESULTS

From a total of 1485 patients who were consecutively admitted to hospital, the data of 1317 (87%) patients could be included for further analysis. During the hospital stay 146 (11%) patients fell at least once, 35 (3%) patients had more than 1 fall and 64 falls (44%) occurred while patients were standing (bipedal fall). Daytime sleepiness was observed in 73% of the patients with bipedal falls and in 65% patients with nonbipedal falls (p < 0.01). Falls correlated significantly with the history of a recent fall, the length of hospital stay, the Barthel index (BI) on admission, the mini mental state examination (MMSE), dementia and observed daytime sleepiness. No correlation was found between falls and age, multimorbidity, and the number of drugs used. Drugs related to falls were medications to treat Parkinson's disease, antidepressants and neuroleptics. In a multiple logistic regression analysis in-hospital falls were significantly and independently associated with a history of falls, length of in-hospital stay, dementia, and observed daytime sleepiness.

CONCLUSION

Observed daytime sleepiness is associated with in-hospital falls in geriatric patients. Prospective interventional studies are needed to confirm this relationship, and to quantify the impact of sleepiness on the risk of falling. Additionally, the impact of treatment for observed daytime sleepiness on the risk of falling should be assessed. The assessment of sleepiness should become a routine task in geriatrics.

Adherence to a healthy sleep pattern is associated with lower risks of incident falls and fractures during aging

Background

Autoimmune diseases are more common among people with unhealthy sleep behaviors, and these conditions have been linked to aging-related bone health. However, there have been few studies that examined the correlation between recently developed sleep patterns based on sleep duration, sleepiness, chronotype, snoring, insomnia, and the incidence of falls and fractures.

Methods

We used a newly developed sleep pattern with components of sleep 7 to 8 h per day, absence of frequent excessive daytime sleepiness, early chronotype, no snoring, and no frequent insomnia as healthy factors to study their relationship with the incidence of falls and fractures. The analysis was conducted among 289,000 participants from the UK Biobank.

Results

The mean follow-up period was 12.3 years (3.5 million person-years of follow-up), and 12,967 cases of falls and 16,121 cases of all fractures were documented. Compared to participants exhibiting an unfavorable sleep pattern, those adhering to a healthy sleep pattern experienced a 17% and 28% reduction in the risks of incident falls (hazard ratio [HR], 0.83; 95% CI, 0.74-0.93) and all fractures (HR, 0.72; 95% CI, 0.66-0.79) during follow-up. In addition, participants exhibiting a healthy sleep pattern, together with a high genetically determined bone mineral density (BMD), showed the lowest risks of falls and fractures.

Conclusion

A healthy sleep pattern was significantly linked to decreased risks of incident falls and fractures. The protective association was not modified by genetically determined BMD.

The relationships between sleep disturbance and falls: A systematic review

The purpose of this systematic review was to examine critically the literature that addresses the association between sleep disturbance and falls. Electronic databases OVID MEDLINE, PubMed, and CINAHL were searched using MeSH terms "sleep" and "accidental falls." Search limits included adults, humans, and English. The articles selected for the final sample were assessed for methodological quality. Eleven key attributes of sleep disturbance were extracted. The search yielded 177 articles from OVID MEDLINE, 124 from PubMed, and 46 from CINAHL. The final sample included 42 papers. The mean methodological quality score was 7.5 (range 2-10). Those who self-report >11 h or ≤5 h of nocturnal sleep duration may have a greater fall risk, but variations in cutoff points, study designs, and data collection methods contribute to difficulty in comparing study results. Subjective sleep fragmentation is associated with falls. The few studies on obstructive sleep apnea and insomnia demonstrate evidence of an increased risk for falls. It remains unclear whether daytime sleepiness, self-reported sleep quality, snoring, or napping are associated with falls, since some but not all studies demonstrate an association and the study quality did not differ.

The relationship between the severity of insomnia and falls in the elderly

BACKGROUND

Insomnia is associated with depression, cognitive impairment, hypertension, myocardial infarction, stroke, metabolic syndrome and prostate cancer in the elderly. The aim of this study is to investigate the relationship between severity of insomnia and falls.

METHODS

This cross-sectional study was conducted in a single geriatric outpatient clinic at a university teaching hospital. Patients with active infection, who could not complete insomnia severity index (ISI) test because of cognitive impairment and who could not perform handgrip strength and timed up and go (TUG) tests were excluded from the study.

RESULTS

A total of 215 patients were included in this study. Logistic regression analysis showed that there is significant relationship between poorer TUG performance, mild insomnia, moderate insomnia, severe insomnia and falls in the elderly (odds ratio (OR) = 1.04, CI: 1.00-1.09, P = 0.041, OR = 2.43, CI: 1.22-4.85, P = 0.011, OR = 3.84, CI:1.35-10.94, P = 0.012, OR = 5.81, CI:1.00-33.72, P = 0.050).

CONCLUSIONS

In this study we showed that there is a relationship between the severity of insomnia and falls.

The impact of urinary incontinence on falls: A systematic review and meta-analysis

OBJECTIVE

Previous studies on the association between urinary incontinence (UI) and falls have reported conflicting results. We, therefore, aimed to evaluate and clarify this association through a systematic review and meta-analysis of relevant studies.

METHODS

We performed a literature search for relevant studies in databases including PubMed and EMBASE from inception up to December 13, 2020, using several search terms related to UI and falls. Based on the data reported in these studies, we calculated the pooled odds ratios (ORs) for falls and the corresponding 95% confidence intervals (CIs) using the Mantel-Haenszel method.

RESULTS

This meta-analysis included 38 articles and a total of 230,129 participants. UI was significantly associated with falls (OR, 1.62; 95% CI, 1.45-1.83). Subgroup analyses based on the age and sex of the participants revealed a significant association between UI and falls in older (≥65 years) participants (OR, 1.59; 95% CI, 1.31-1.93), and in both men (OR, 1.88; 95% CI, 1.57-2.25) and women (OR, 1.41; 95% CI, 1.29-1.54). Subgroup analysis based on the definition of falls revealed a significant association between UI and falls (≥1 fall event) (OR, 1.61; 95% CI, 1.42-1.82) and recurrent falls (≥2 fall events) (OR, 1.63; 95% CI, 1.49-1.78). According to the UI type, a significant association between UI and falls was observed in patients with urgency UI (OR, 1.76; 95% CI, 1.15-1.70) and those with stress UI (OR, 1.73; 95% CI, 1.39-2.15).

CONCLUSIONS

This meta-analysis, which was based on evidence from a review of the published literature, clearly demonstrated that UI is an important risk factor for falls in both general and older populations.

Associations between sleep duration, midday napping, depression, and falls among postmenopausal women in China: a population-based nationwide study

OBJECTIVE

To explore the independent and joint associations of sleep duration, midday napping, and depression with fall accidents in Chinese postmenopausal women.

METHODS

A total of 2,378 postmenopausal women aged ≥ 45 years from the baseline survey of the China Health and Retirement Longitudinal Study were enrolled in the study. Each participant provided data on falls, sleep duration, midday napping by a self-reporting approach. We employed the Chinese version of the Center for Epidemiologic Studies Depression Scale to assess depression. Adjusted odds ratios (OR) and 95% confidence intervals (CI) were calculated to estimate the associations of predictor variables with falls using multivariate logistic regression.

RESULTS

Of the 2,378 postmenopausal women, 478 (20.10%) reported falls in the preceding 2 years. Compared with sleep duration of 7 to 8 h/night, sleep duration of 5 to 6 h/night (OR, 1.49; 95% CI, 1.03-2.15) and of ≤ 5 h/night (OR, 1.63; 95% CI, 1.18-2.25) were associated with a higher fall prevalence. However, no significant correlation was found between sleep duration of > 8 h/night and falls. Furthermore, participants with depression were more likely to report falls (OR, 1.78; 95% CI, 1.41-2.25) than their depression-free counterparts. The duration of midday napping was not independently associated with falls, but significant joint associations of sleeping ≤ 6 h/night and no napping (OR, 1.72; 95% CI, 1.07-2.76) or napping > 60 minutes (OR, 2.14; 95% CI, 1.18-3.89) with more falls were found. Similarly, a combined status of sleeping ≤ 6 h/night and depression was related to more falls (OR, 2.97; 95% CI, 1.86-4.74).

CONCLUSION

The present study demonstrates that short sleep duration and depression are independently associated with more falls among postmenopausal women in China. Moreover, short sleep duration combined with no or long napping, short sleep duration combined with depression are jointly correlated with more falls. Future longitudinal studies are warranted to confirm these findings.

Independent and synergistic effects of pain, insomnia, and depression on falls among older adults: a longitudinal study

Background

Few studies have examined the relationship between falls and pain, insomnia and depressive symptoms which are common and risk factors in older adults. We aimed to examine the independent and synergistic effects of these risk factors on future falls among older adults.

Methods

We used data of 2558 community-dwelling older adults from 2011 (Y1) to 2015 (Y5) of the National Health and Aging Trends Study (NHATS). Pain was determined by whether participants reported bothersome pain in the last month. Insomnia was assessed by two questions about how often the participants had trouble falling asleep and maintaining sleep. Depressive symptoms were assessed by Patient Health Questionnaire-2. Generalized estimation equation (GEE) models were used to examine the independent effects of pain, insomnia and depressive symptoms at prior-wave (period y-1) on falls at current wave (period y) adjusting for covariates (age, sex, education, race/ethnicity, living arrangement, BMI, smoking, vigorous activities, number of chronic illnesses and hospitalization). The significance of the three-way interaction of these factors (pain*insomnia*depression) was tested using the aforementioned GEE models to determine their synergistic effects on falls.

Results

Overall, the participants were mainly 65–79 years old (68%), female (57%) and non-Hispanic White (70%). At Y1, 50.0% of the participants reported pain, 22.6% reported insomnia and 9.9% reported depressive symptoms. The incidence of falls from Y2 to Y5 was 22.4, 26.0, 28.3, and 28.9%, respectively. Participants with pain (Odds ratio [OR], 95% confidence interval [CI] = 1.36, 1.23–1.50) and depressive symptoms (OR, 95% CI = 1.43, 1.23–1.67) had high rates of falling adjusting for covariates. After further adjustment for insomnia and depressive symptoms, pain independently predicted falls (OR, 95% CI = 1.36, 1.22–1.51). Depressive symptoms also independently predicted falls after further adjusting for pain and insomnia (OR, 95% CI = 1.40, 1.20–1.63). After adjusting for pain and depression, the independent effects of insomnia were not significant. None of the interaction terms of the three risk factors were significant, suggesting an absence of their synergistic effects.

Conclusions

Pain and depressive symptoms independently predict falls, but synergistic effects seem absent. Further research is needed to develop effective strategies for reducing falls in older adults, particularly with pain and depressive symptoms.

Kidney function and other factors and their association with falls : The screening for CKD among older people across Europe (SCOPE) study

Background

Reduced kidney function has become a major public health concern, especially among older people, as Chronic Kidney Disease (CKD) is associated with increased risk of end stage renal disease and mortality. Falls are a serious negative health outcome in older persons with one third of people aged 65 years experiencing a fall per year and increasing fall rates with increasing age. The impact of CKD on falls in older community-dwelling persons is not well investigated. Additionally, lower urinary tract symptoms (LUTS) may also increase the risk of falls. Therefore, our aim was to investigate the impact of CKD and LUTS on falls as well as on injurious falls.

Methods

The SCOPE study is an observational, multinational, multicenter, prospective cohort study involving community-dwelling older persons aged 75 years and more recruited from August 2016 to March 2018 in seven European countries. The main outcomes of the present study were any falls and any injurious falls during the 12 months before enrolment. The cross-sectional association of estimated glomerular filtration rate (eGFR) and LUTS with study outcomes was investigated by logistic regression analysis adjusted for baseline characteristics of enrolled subjects.

Results

Our series consisted of 2256 SCOPE participants (median age = 79.5 years, 55.7% female). Of them, 746 participants experienced a fall and 484 reported an injurious fall in the 12 months prior to baseline assessment. CKD was not significantly associated with falls (OR = 0.95, 95%CI = 0.79–1.14 for eGFR< 60; OR = 1.02, 95%CI = 0.81–1.28 for eGFR< 45; OR = 1.08, 95%CI = 0.74–1.57 for eGFR< 30) or injurious falls (OR = 0.91, 95%CI = 0.67–1.24 for eGFR< 60; OR = 0.93, 95%CI = 0.63–1.37 for eGFR< 45; OR = 1.19, 95%CI = 0.62–2.29 for eGFR< 30). LUTS were found significantly associated with both falls (OR = 1.56, 95%CI = 1.29–1.89) and injurious falls (OR = 1.58, 95%CI = 1.14–2.19), and such associations were confirmed in all multivariable models.

Conclusions

Cross-sectional data suggest that CKD may not be associated with history of falls or injurious falls, whereas LUTS is significantly associated with the outcomes.

Trial registration

This study was registered on 25th February 2016 at clinicaltrials.gov (NCT02691546).

Association Between Subjective Sleep Quality and Future Risk of Falls in Older People: Results From LOHAS

Background

Inadequate sleep is correlated with morbidity and mortality among older adults. However, the longitudinal relationship between subjective sleep quality and risk of falls in the elderly population remains to be clarified.

Methods

Study participants were from Locomotive Syndrome and Health Outcome in Aizu Cohort Study (LOHAS) sites (1,071 community-dwelling people ≧65 years of age, mean: 71 years). Subjective sleep quality was measured by the Pittsburgh Sleep Quality Index (PSQI). Occurrence of falls (defined as experiencing at least one fall) during the subsequent year was ascertained by a self-reported questionnaire.

Results

Mean global PSQI score was 4.3 (SD 3.2), with 28.9% of participants rating their sleep quality as poor (PSQI > 5). A total of 210 participants (19.6%) fell at least once in the year following sleep examination. Multivariable analysis revealed that participants reporting worse subjective sleep quality had significantly higher odds of experiencing falls during the 1-year follow-up period (adjusted odds ratio [AOR] = 1.50 for each three-point increase in global PSQI score; 95% confidence interval [CI] = 1.20, 1.89). Participants in the highest global PSQI score (PSQI > 5) quartile had significantly increased odds of experiencing falls compared to those in the lowest global score quartile (PSQI < 2; AOR = 2.14; 95% CI = 1.09, 4.22). This association was similarly significant in subgroup analyses for older men and women, nonusers of sleep medication, and those without a history of falls at baseline.

Conclusion

Subjective poor sleep quality, as measured by the PSQI, is longitudinally associated with greater risk of experiencing falls in community-dwelling older adults.

Incidence of falls among community-dwelling older adults in Turkey and its relationship with pain and insomnia

AIM

The aim of this study was to determine the incidence of falls among community-dwelling older adults and the impact of pain and insomnia on falls.

METHODS

This cross-sectional study recruited 659 older adults. Pain was assessed by the Geriatric Pain Measure, and insomnia was assessed by the Insomnia Severity Index. The history of falls was assessed within the last 12 months. Risk factors for falls were determined using logistic regression analysis.

RESULTS

The incidence of falls within the last year was 37.2%. Based on the analyses, pain and insomnia were found to be risk factors for falls.

CONCLUSION

In this study, falls were observed as a common problem among community-dwelling older adults, and pain and insomnia were determined as risk factors for falls. Therefore, pain and insomnia should be addressed when prevention of falls among community-dwelling older adults are planned by health care professionals including nurses.

Fall Risk Classification in Community-Dwelling Older Adults Using a Smart Wrist-Worn Device and the Resident Assessment Instrument-Home Care: Prospective Observational Study

Background

 Little is known about whether off-the-shelf wearable sensor data can contribute to fall risk classification or complement clinical assessment tools such as the Resident Assessment Instrument-Home Care (RAI-HC).

Objective

 This study aimed to (1) investigate the similarities and differences in physical activity (PA), heart rate, and night sleep in a sample of community-dwelling older adults with varying fall histories using a smart wrist-worn device and (2) create and evaluate fall risk classification models based on (i) wearable data, (ii) the RAI-HC, and (iii) the combination of wearable and RAI-HC data.

Methods

 A prospective, observational study was conducted among 3 faller groups (G₀, G₁, G₂₊) based on the number of previous falls (0, 1, ≥2 falls) in a sample of older community-dwelling adults. Each participant was requested to wear a smart wristband for 7 consecutive days while carrying out day-to-day activities in their normal lives. The wearable and RAI-HC assessment data were analyzed and utilized to create fall risk classification models, with 3 supervised machine learning algorithms: logistic regression, decision tree, and random forest (RF).

Results

 Of 40 participants aged 65 to 93 years, 16 (40%) had no previous falls, whereas 8 (20%) and 16 (40%) had experienced 1 and multiple (≥2) falls, respectively. Level of PA as measured by average daily steps was significantly different between groups (P=.04). In the 3 faller group classification, RF achieved the best accuracy of 83.8% using both wearable and RAI-HC data, which is 13.5% higher than that of using the RAI-HC data only and 18.9% higher than that of using wearable data exclusively. In discriminating between {G₀+G₁} and G₂₊, RF achieved the best area under the receiver operating characteristic curve of 0.894 (overall accuracy of 89.2%) based on wearable and RAI-HC data. Discrimination between G₀ and {G₁+G₂₊} did not result in better classification performance than that between {G₀+G₁} and G₂₊.

Conclusions

 Both wearable data and the RAI-HC assessment can contribute to fall risk classification. All the classification models revealed that RAI-HC outperforms wearable data, and the best performance was achieved with the combination of 2 datasets. Future studies in fall risk assessment should consider using wearable technologies to supplement resident assessment instruments.

Nursing Home Eligible, Community-Dwelling Older Adults' Perceptions and Beliefs About Sleep: A Mixed-Methods Study

Sleep disturbances are highly prevalent in older adults; little is known about sleep in those who remain living in the community despite qualifying for nursing home placement. We conducted a concurrent, nested, mixed-methods study to describe sleep characteristics and sleep disturbances in this population. Our final sample (n = 40) was Black (100%), female (85%) older adults with a mean (±SD) age of 72 ± 9.5 years. Of these, 35 had objectively measured short or long sleep duration, and 30 had subjectively reported poor sleep quality. Our evidence suggests that sleep disturbances are common in this group, and these older adults had adjusted their expectations and adapted to their sleep disturbances. Given that at-risk older adults may not perceive their sleep disturbances as problematic, clinicians must proactively assess sleep and educate about the importance of sleep. These results reveal modifiable factors with potential to improve health outcomes in this vulnerable population.

[Palliative long-term urinary bladder drainage: the uro-geriatric point of view]

A serious voiding disorder or urinary incontinence represent indications for long-term catheterization of the urinary bladder. Treatment by a transurethral or suprapubic bladder catheter for life-long bladder drainage is accompanied by technical short-term complications and long-term sequelae. The mortality risk associated with inserting a suprapubic catheter is approximately 2% due to an incorrect bladder puncture. Long-term consequences of life-long bladder drainage are hematuria, infection, spasms, stone formation, obstruction, catheter loss, risk of falls and automanipulation especially in cognitively impaired persons. These constitute frequent reasons for emergency treatment or hospitalization. Further problem areas are dependency on caregivers to perform the catheter change and dermal problems in the area of the fistula stoma. To what extent this limits the quality of life of those affected remains unclear up to now. The acute complications and the long-term consequences of life-long bladder drainage make careful decision-making necessary after other therapeutic options have failed, are not appropriate or not desired.

Urinary Incontinences Are Related with Fall and Fragility Fractures in Elderly Population: Nationwide Cohort Study

Background

This prospective cohort study used nationwide claims data to investigate the incidence of fall and fragility fractures in association with urinary incontinence (UI) in the elderly, and to compare mortality after fragility fractures in elderly patients with or without incontinence.

Methods

A total of 39,854 Korean adults (age, 66-80 years) who participated in health examinations between 2007 and 2012 and were followed up until 2015 were analyzed. Patient and comparison groups were classified according to the presence or absence of UI. The cumulative incidence of osteoporotic fragility fractures and falls in the 2 groups was assessed and compared. Hazard ratios for fragility fractures were calculated for the risk of UI in association with falls using a Cox proportional hazards model.

Results

Of 39,854 elderly participants, 5,703 were classified in the UI group, while 34,151 were placed in the comparison group. Fall rates were significantly higher (20.8%) in the incontinence group than in the comparison group (4.7%) (P<0.001). Women in the incontinence group (13.9%) showed a significantly higher incidence of all types of fragility fractures than those in the comparison group (11.8%) (P=0.005). After adjustment for confounders, UI was not a significant risk factor for fragility fractures in men (P=0.878) or women (P=0.324).

Conclusions

This study demonstrated that elderly women with UI have a significantly higher incidence of osteoporotic fragility fractures. In addition, elderly women are at higher risk for falls.

The Association Between Overactive Bladder and Falls and Fractures: A Systematic Review

Introduction

Urinary symptoms are associated with an increased risk of falls, but few studies have focused on patients with overactive bladder (OAB). This study aimed to synthesize estimates of the risk of falls and fractures in patients with OAB.

Methods

Medline, EMBASE, the Cumulative Index to Nursing and Allied Health Literature, and Scopus were systematically searched for observational studies that focused on patients with OAB. When available, data from a non-OAB comparison sample were included. Double independent review and data extraction were performed. Falls and fractures data were summarized by unadjusted and adjusted risks, and percent attributable risk (PAR) of falls and fractures associated with OAB.

Results

Fifteen studies were included in the analyses. The proportion of patients with OAB experiencing at least one fall over a year ranged from 18.9% to 50.0%, and the proportion of patients with OAB experiencing recurrent or serious falls ranged from 10.2% to 56.0%. In studies that included a non-OAB comparison sample, a higher risk of falls was observed in patients with OAB compared to those without. A significantly increased (1.3- to 2.3-fold) adjusted OAB-associated risk of falls was reported, while unadjusted PARs for OAB associated falls ranged from 3.7% to 15.5%. Risk was higher among women and those 65 years of age or older. While analysis of fractures showed elevated point estimates, most studies were underpowered to detect a statistically significant difference between groups.

Conclusions

Evidence from the published literature clearly demonstrates the importance of OAB and its symptoms as risk factors for falls and fractures.

Sex Differences in Lower Urinary Tract Symptoms in Older Korean Adults Living in Rural Areas: Prevalence, Quality of Life, and Associated Factors

Purpose

Urinary incontinence (UI) is associated with nursing home admission, functional decline, and risk of death among community-dwelling older adults. Little information, however, is available on sex differences in lower urinary tract symptoms (LUTS) in older Korean adults exclusively living in rural areas. This study examined sex-related differences in LUTS, factors associated with UI in older adults living in rural areas, and health-related quality of life (HRQoL) in incontinent older adults.

Methods

This was a cross-sectional study in which face-to-face interviews were conducted at 15 rural community-health centres. A total of 323 older adults aged ≥65 years from rural areas of Korea participated. LUTS prevalence was evaluated and HRQoL was measured using the King’s Health Questionnaire. The chi-square test and t -test were used to examine sex differences in characteristics, LUTS, and HRQoL. Multivariable logistic regression was used to identify risk factors associated with UI.

Results

Nocturia was the most prevalent symptom, affecting 87% of men and 86% of women. Women (53%) had significantly more UI of any kind than did men (35%) (P=0.007). Urgency UI was the most frequent type of UI in men, whereas stress UI was the most frequent in women. Regarding HRQoL, men had significantly higher scores in the domains of sleep/energy disturbances (P=0.032) than did women, and women reported greater effects from the severity of incontinence (P=0.001) than did men. Arthritis was the only factor associated with UI in men (odds ratio [OR], 6.88; 95% confidence interval [CI], 1.46–32.36). However, women with diabetes mellitus were less likely to have UI than those without (OR, 0.43; 95% CI, 0.23–0.82).

Conclusions

LUTS were found to be highly prevalent in community-dwelling older Korean adults in rural areas. Interventions to improve sleep and to reduce UI severity are needed for incontinent men and women, respectively.

Effects of Pain and Sleep Quality on Falls Among Nursing Home Residents in Turkey

The current study was conducted to detect the incidence of falls among individuals in nursing homes, as well as the impact of pain and sleep quality on falls. The sample for this cross-sectional study comprised 291 older adults. Pain was assessed using the Geriatric Pain Measure and insomnia was assessed using the Insomnia Severity Index. Incidence of falls within the past 1 year was 40.9%. Risk factors for falling were determined using logistic regression analysis. Based on the analysis, being single (odds ratio [OR] = 2.502, 95% confidence interval [CI] [1.155, 6.195]) and experiencing pain (OR = 2.841, 95% CI [1.195-6.754]) were risk factors for falling. In the current study, falling was seen as a common problem among older adults. Pain in particular should be addressed when planning the prevention of falls in nursing homes. [Res Gerontol Nurs. 2018; 11(5):257-264.].

Urinary incontinence and sleep complaints in community dwelling older adults

Sleep disorder is associated with poor quality of life in old age. Therefore, it is imperative to identify contributing factors leading to sleep disorder. The current study aimed to examine the impact of urinary incontinence on sleep complaint after controlling for potential sociodemographic and health covariates. Materials and Methods: A cross-sectional study was conducted on a sample of 184 community dwelling older adults 60 years and older in Yazd, Iran, 2016. In order to obtain the sample a multistage proportional random sampling technique was employed. Sociodemographic characteristics, sleep complaint, and urinary incontinence were collected from medical records. Statistical analyses were performed using SPSS version 24. A multiple logistic regression analysis was used to examine the impact of urinary incontinence on sleep complaint after controlling for potential covariates. Findings: A total of 184 respondents with a mean age of 68.48±6.65 years (age range, 60-87 years) were included in the study. About 70% of the respondents were women, 72.8% were married, 68.5% were not formally educated, and 21.7% were living alone. The prevalence of sleep complaint and urinary incontinence were 27.2% (95% CI: 21-34) and 22.3% (95% CI: 17-29), respectively. The results of the multiple logistic regression analysis revealed respondents with urinary incontinence were four times more likely to suffer from sleep complaint than those without urinary incontinence after adjusting for potential covariates (AOR=4.04, 95% CI: 1.74-9.35, p<0.001). Conclusion: Based on the results of this present study, which showed that urinary incontinence independently contributed to sleep complaint among older adults, it is necessary to employ effective interventions for controlling urinary incontinence to reduce sleep complaints.

Sleep duration and falls: a systemic review and meta-analysis of observational studies

Several epidemiological studies have linked sleep duration with falls; however, the findings yielded inconsistent results. No quantitative analysis has specifically assessed the influence of sleep duration on falls. PubMed and Embase were screened for observational studies from inception to 13 September 2016. A generic inverse-variance method was used to pool the outcome data for sleep duration categories of the lowest category versus reference, and the highest category versus reference with a random-effects model. Dose-response analysis was performed to evaluate the potential relationship of sleep duration with falls. Finally, seven eligible observational studies involving a total of 212 829 participants were included in the present meta-analysis. Compared with the reference category, both short and long sleep duration were significantly associated with falls, and the pooled odds ratios (95% confidence intervals) were 1.32 (1.21, 1.46) and 1.35 (1.17, 1.56), respectively, both with evidence of significant heterogeneity. An approximately 'U-shaped' curve was observed, and the lowest risk of falls was shown at 7-8 h day-1 of sleep duration. Further subgroup analysis found that the association of long sleep duration and falls was more pronounced among Caucasians. The present study is limited to its small number of included studies, considerable heterogeneity, observational study design and the large contribution of a single article. Further researches are still needed to confirm the causal association between sleep duration and falls in populations with different gender, age and ethnicity.

Poor Sleep and Risk of Falls in Community-Dwelling Older Adults: A Systematic Review

Concerns about sleep problems and falls in older adults are significant. This article reviews the association between sleep problems and falls in community-dwelling adults aged 65 years or older. Multiple databases were searched from inception until 2015 using sleep, sleep disorders, and falls as keywords, limiting to studies published in English in peer-reviewed journals. After screening and assessing for eligibility, 18 articles were selected based on the inclusion and exclusion criteria. Findings of an association between sleep problems and risk of falls are conflicting, but some specific sleep problems such as extremely short sleep duration, daytime sleepiness and naps appear to be significantly related to falls in older adults. Methodological limitations including variability in covariates included in the analyses and measurement of the exposure and outcome variables were identified. The results of this review identified the need to have comparable definitions, validated tools, and rigorous design of future studies.

Balance and Mobility in Community-Dwelling Older Adults: Effect of Daytime Sleepiness

OBJECTIVES

To examine the effect of self-reported daytime sleepiness on performance-based balance measures and self-reported balance confidence in community-dwelling older adults.

DESIGN

Cross-sectional secondary analysis of an observational cohort study designed to develop and refine measures of balance and mobility in community-dwelling older adults.

SETTING

Community.

PARTICIPANTS

Older adults (aged 78.2 ± 5.9) (n = 120).

MEASUREMENTS

The performance-based gait and balance measures included gait speed, double support time, and step width. Narrow walk, obstacle walk, and timed standing balance were also assessed. The Activities-Specific Balance Confidence Scale was included as a self-reported measure. Daytime sleepiness was defined as an Epworth Sleepiness Scale score of 9 or greater. Body mass index, fall-related comorbidities, and use of central nervous system (CNS) medications were considered as covariates.

RESULTS

Forty-five percent of participants reported daytime sleepiness. Participants reporting daytime sleepiness differed significantly from those without in gait speed (adjusted difference (standard error (SE)) -0.09 (0.04) m/s, P = .03), step width (adjusted difference (SE) 0.02 (0.01), P = .03), and self-reported balance confidence (adjusted difference (SE) -1.02 (0.38), P = .01) even after adjusting for covariates. Two-way analysis of variance of CNS medication use and daytime sleepiness showed no significant interaction effects.

CONCLUSION

Self-reported daytime sleepiness is associated with slower gait speed and poor balance confidence in community-dwelling older adults. Subjective sleep assessment should be considered when assessing balance and implementing interventions for improving balance in older adults. Further study is needed to examine the role of CNS medication use.

Report and Research Agenda of the American Geriatrics Society and National Institute on Aging Bedside-to-Bench Conference on Sleep, Circadian Rhythms, and Aging: New Avenues for Improving Brain Health, Physical Health, and Functioning

The American Geriatrics Society, with support from the National Institute on Aging and other funders, held its eighth Bedside-to-Bench research conference, entitled "Sleep, Circadian Rhythms, and Aging: New Avenues for Improving Brain Health, Physical Health and Functioning," October 4 to 6, 2015, in Bethesda, Maryland. Part of a conference series addressing three common geriatric syndromes-delirium, sleep and circadian rhythm (SCR) disturbance, and voiding dysfunction-the series highlighted relationships and pertinent clinical and pathophysiological commonalities between these three geriatric syndromes. The conference provided a forum for discussing current sleep, circadian rhythm, and aging research; identifying gaps in knowledge; and developing a research agenda to inform future investigative efforts. The conference also promoted networking among developing researchers, leaders in the field of SCR and aging, and National Institutes of Health program personnel.

Age- and gender-specific associations between insomnia and falls in Boston Puerto Rican adults

PURPOSE

This study evaluated the age- and gender-specific associations between insomnia and falls in community-dwelling Puerto Rican adults, independently of multiple covariates.

METHODS

Cross-sectional data were collected from 954 Puerto Ricans, aged 46-79 years, in Boston, Massachusetts. In-person interviews were conducted to collect information on sociodemographics and lifestyle, mental status, medication use, comorbidities, sleep duration, insomnia symptoms, and falls and fractures. Blood and urine samples, and bone density measures were collected to assess C-reactive protein, serum interleukin-6, urinary cortisol, and bone mineral density.

RESULTS

Multivariate robust Poisson regressions suggested that adults with insomnia had a 32 % increased likelihood of having falls (PR 1.32, p < 0.05), after adjustment for multiple covariates. Age and gender modified the effect of insomnia on risk of falls. Insomnia was significantly associated with higher risk of falls in adults of 60 years or older (PR 1.49, p < 0.05) and in women (PR 1.36, p < 0.05), but not in adults younger than 60 years or in men. Insomnia was not associated with recurrent falls or fractures.

CONCLUSIONS

Age and gender need to be taken into account when considering treatment of insomnia in preventing geriatric falls. Well-designed evidence-based interventions to treat insomnia and improve sleep quality may reduce the risk of falls in this population.

The Association between Sleep Problems, Sleep Medication Use, and Falls in Community-Dwelling Older Adults: Results from the Health and Retirement Study 2010

Background. Very few studies have assessed the impact of poor sleep and sleep medication use on the risk of falls among community-dwelling older adults. The objective of this study was to evaluate the association between sleep problems, sleep medication use, and falls in community-dwelling older adults. Methods. The study population comprised a nationally representative sample of noninstitutionalized older adults participating in the 2010 Health and Retirement Study. Proportion of adults reporting sleep problems, sleep medication use, and fall was calculated. Multiple logistic regression models were constructed to examine the impact of sleep problems and sleep medication use on the risk of falls after controlling for covariates. Results. Among 9,843 community-dwelling older adults, 35.8% had reported a fall and 40.8% had reported sleep problems in the past two years. Sleep medication use was reported by 20.9% of the participants. Older adults who do have sleep problems and take sleep medications had a significant high risk of falls, compared to older adults who do not have sleep problems and do not take sleep medications. The other two groups also had significantly greater risk for falls. Conclusion. Sleep problems added to sleep medication use increase the risk of falls. Further prospective studies are needed to confirm these observed findings.

Lower Urinary Tract Symptoms and Incident Falls in Community Dwelling Older Men: The Concord Health and Ageing in Men Project

PURPOSE

We sought to determine which lower urinary tract symptoms are associated with incident falls in community dwelling older men.

MATERIALS AND METHODS

The Concord Health and Ageing in Men Project involves a representative sample of community dwelling men 70 years old or older in a defined geographic region in Sydney, New South Wales, Australia. Included in analysis were 1,090 men without neurological diseases, poor mobility or dementia at baseline. Lower urinary tract symptoms were assessed using I-PSS (International Prostate Symptom Score) and incontinence was assessed using ICIQ (International Consultation on Incontinence Questionnaire) at baseline. I-PSS subscores were calculated for storage and voiding symptoms. Incident falls in 1 year were determined by telephone followup every 4 months.

RESULTS

I-PSS storage and voiding subscores were associated with falls. Urgency incontinence was associated with falls (adjusted incidence rate ratio 2.57, 95% CI 1.54-4.30). In addition, intermediate to high I-PSS storage subscores without urgency incontinence were associated with falls (adjusted incidence rate ratio 1.72, 95% CI 1.24-2.38). Other types of incontinence and urgency alone without urgency incontinence were not associated with falls.

CONCLUSIONS

Lower urinary tract storage and voiding symptoms were associated with falls in community dwelling older men. Of the symptoms of overactive bladder urgency incontinence carried a high risk of falls. Storage symptoms also contributed to the fall risk independently of urgency incontinence. Circumstances of falls among men with lower urinary tract symptoms should be explored to understand how lower urinary tract symptoms increase the fall risk and generate hypotheses regarding potential interventions. Furthermore, trials to treat lower urinary tract symptoms in older men should include falls as an end point.

Excessive Sleep and Lack of Sleep Are Associated With Slips and Falls in the Adult Korean Population: A Population-Based Cross-Sectional Study

Few studies have evaluated the impacts of excessive sleep duration on falls. This study investigated the associations between sleep duration and falls among Korean adults in a wide range of age groups while adjusting for numerous confounding factors. Data collected from study participants ranging in age from 19 to 109 years old were analyzed from the 2013 Korean Community Health Survey (KCHS). Sleep duration was divided into 5 groups: ≤5, 6, 7, 8, and ≥9  hours per day. The relations between sleep duration and falls (≥1 time or ≥2 times per year) were analyzed using simple and multiple logistic regression analyses with complex sampling. Age, sex, days of vigorous or moderate physical activity, income, education, alcohol use, smoking, stress, obesity, hypertension, diabetes mellitus, hyperlipidemia, stroke, angina or myocardial infarction, arthritis, and asthma were controlled for as confounding factors. Associations between sleep duration and falls were analyzed in 19 to 40, 41 to 60, and 61+ year age groups. Furthermore, the relations between sleep duration and indoor versus outdoor falls were analyzed. Both ≤6 and ≥8  hours of sleep per day were significantly associated with an increased incidence of falls (≥1 time and ≥2 times per year) in the overall adult population (P < 0.001 in both instances). In a subgroup analysis, sleep durations of ≤5 and ≥9  hours were significantly associated with an increased incidence of falls (≥1 time a year) in each age group. Six hours of sleep was not significantly associated with falls (≥2 times per year) in the 61+ year age group, and 8 and 9  hours of sleep were not significantly associated with falls (≥2 times a year) in the 19 to 40 year age group. This study demonstrated that long as well as short sleep durations are associated with an increased incidence of falls. However, these relations were not evident in elderly populations with short sleep durations or in young adults with long sleep durations.

Correlates of excessive daytime sleepiness in community-dwelling older adults: an exploratory study

Excessive daytime sleepiness (EDS) imposes a wide range of adverse health-related outcomes in older people, such as disability, which impair everyday activities and may increase the risk of fall. Few studies have explored EDS in Brazilian older people living in the community who are typically cared in primary health services. This study aims to investigate the prevalence of EDS and its sociodemographic, physical and mental health correlates among community-dwelling older adults. This is an exploratory, population-based study derived from Frailty in Brazilian Older Adults (FIBRA) study including adults aged 65 years and older. Participants with a score ≥ 11 points on the Epworth Sleepiness Scale were considered as having excessive daytime sleepiness. A structured, multidimensional questionnaire was used to investigate sociodemographic, physical and mental health, and self-rated health variables. The sample was composed of 776 older adults, of whom 21% (n = 162) presented excessive daytime sleepiness. Multivariate regression analysis revealed that EDS is associated with obesity (OR = 1.50; 95%CI 1.02 - 2.20), urinary incontinence (OR = 1.53; 95%CI 1.01 - 2.31), poor self-rated health (OR = 1.54; 95%CI 1.06 - 2.24), and depression symptoms (OR = 1.49; 95%CI 1.00 - 2.20). Our results suggest that healthcare professionals should identify older adults with EDS and implement intervention strategies to minimize the negative impact of the co-occurrence of this condition with obesity, depression and urinary incontinence over health and quality of life.

Excessive daytime sleepiness and falls among older men and women: cross-sectional examination of a population-based sample

Background

Excessive daytime sleepiness (EDS) has been associated with an increased risk for falls among clinical samples of older adults. However, there is little detailed information among population-representative samples. The current study aimed to assess the relationship between EDS and falls among a cohort of population-based older adults.

Methods

This study assessed 367 women aged 60-93years (median 72, interquartile range 65-79) and 451 men aged 60-92years (median 73, interquartile range 66-80) who participated in the Geelong Osteoporosis Study between the years 2001 and 2008. Falls during the prior year were documented via self-report, and for men, falls risk score was obtained using an Elderly Fall Screening Test (EFST). Sleepiness was assessed using the Epworth Sleepiness Scale (ESS), and scores of ≥ 10 indicated EDS. Differences among those with and without EDS in regard to falls were tested using logistic regression models.

Results

Among women, 50 (13.6 %) individuals reported EDS. Women with EDS were more likely to report a fall, and were more likely to report the fall occurring outside. EDS was similarly associated with an increased risk of a fall following adjustment for use of a walking aid, cases of nocturia and antidepressant medication use (adjusted OR = 2.54, 95 % CI 1.24-5.21). Multivariate modelling revealed antidepressant use (current) as an effect modifier (p < .001 for the interaction term). After stratifying the data by antidepressant medication use, the association between EDS and falls was sustained following adjustment for nocturia among antidepressant non-users (adjusted OR = 2.63, 95 % CI 1.31-5.30). Among men, 72 (16.0 %) individuals reported EDS. No differences were detected for men with and without EDS in regard to reported falls, and a trend towards significance was noted between EDS and a high falls risk as assessed by the EFST (p = 0.06), however, age explained this relationship (age adjusted OR = 2.20, 95 % CI 1.03-1.10).

Conclusions

For women, EDS is independently associated with at least one fall during the previous year, and this is more likely to occur whilst located outside. Amelioration of EDS may assist in improving functional outcomes among these individuals by reducing the risk for falls.

The excess risk of major osteoporotic fractures in hypothyroidism is driven by cumulative hyperthyroid as opposed to hypothyroid time: an observational register-based time-resolved cohort analysis

The long-term relationship between hypothyroidism and fracture risk is challenging to dissect because of the modifying influence of subsequent thyroxine replacement with the potential for excessive replacement doses. We studied changes in serum thyrotropin concentration (TSH) over time and association with fracture risk in real-world patients presenting with elevated TSH. All TSH determinations were done in the same laboratory, which served all hospitals and general practices. The study population consisted of all adults with a first measurement of TSH >4.0 mIU/L (n = 8414) or normal TSH (n = 222,138; comparator). We used a Cox proportional hazards analysis incorporating additional time-dependent covariates to represent initiation of thyroxine replacement and cumulative number of periods with high versus low TSH after index date with a mean follow-up of 7.2 years. Elevated baseline TSH was not associated with an increased risk of hip fracture (HR 0.90; 95% CI, 0.80 to 1.02) or major osteoporotic fractures (HR 0.97; 95% CI, 0.90 to 1.05), nor was subsequent thyroxine prescription predictive of increased risk of fractures. The number of subsequent 6-month periods with low TSH-suggesting excessive thyroxine dosing-was significantly associated with increased risk of both hip fracture (HR 1.09; 95% CI, 1.04 to 1.15) and major osteoporotic fracture (HR 1.10; 95% CI, 1.06 to 1.14). When gender- and age-stratified analyses for major osteoporotic fractures were undertaken, hyperthyroid time was identified as a predictor of fracture risk in postmenopausal women whereas hypothyroid time predicted increased fracture risk in men below age 75 years. In conclusion, among patients who present with an elevated TSH, the long-term risk of hip and other osteoporotic fractures is strongly related to the cumulative duration of periods with low TSH-likely from excessive replacement. An independent effect of elevated TSH could only be observed in young and middle-aged men, suggesting gender-discrepant consequences on risk.

Review of the efficacy and safety of fesoterodine for treating overactive bladder and urgency urinary incontinence in elderly patients

Overactive bladder (OAB) is a common condition, with prevalence rates increasing with advancing age. Symptoms of OAB, including urgency urinary incontinence (UUI), are associated with various co-morbidities in elderly individuals (e.g., falls and fractures, functional impairment, and depression). The current mainstay of pharmacological therapy for OAB is antimuscarinic agents. Until recently, few studies had specifically evaluated the efficacy and safety of antimuscarinics in the treatment of OAB symptoms in elderly patients. This review summarises available evidence from the medical literature on the efficacy and safety of fesoterodine in elderly patients with OAB symptoms, including UUI. The data from unique placebo-controlled fesoterodine trials of elderly and vulnerable elderly patients, together with age-stratified data from post hoc analyses of fesoterodine trials, demonstrate that treatment with fesoterodine 4 or 8 mg results in statistically and clinically significant improvements in OAB symptoms and patient-reported outcomes in many elderly patients. The data indicate that the efficacy of fesoterodine in elderly patients is comparable with that in younger patients. Fesoterodine is generally well tolerated in elderly and vulnerable elderly patients, with low rates of urinary retention and little evidence of central nervous system events or impaired cognition. The data support a favourable benefit-to-risk ratio for fesoterodine in elderly and medically complex vulnerable elderly patients with OAB.

Association between dentures and the rate of falls in dementia

Background

Poor oral health, chronic diseases, functional decline, and low cognitive ability can increase the risk of falls in the elderly.

Objectives

The current study aimed to show the effects of oral health, diabetes mellitus (DM), hypertension (HT), heart disease, functional status, and sociodemographic factors on the risk of falls in elderly with dementia.

Materials and methods

The sample comprised 1,210 Malaysian elderly who were demented and noninstitutionalized. This study was a national cross-sectional survey entitled “Determinants of Health Status among Older Malaysians”. The effects of age, ethnicity, sex differences, marital status, educational level, oral health, DM, HT, heart disease, and functional status on the risk of falls were evaluated. The multiple logistic regression model was used to estimate the effects of contributing variables on the risk of falls in samples.

Results

The prevalence of falls was approximately 17% in subjects. It was found that age (odds ratio [OR] 1.02), non-Malay ethnicity (OR 1.66), heart disease (OR 1.92), and functional decline (OR 1.58) significantly increased the risk of falls in respondents (P<0.05). Furthermore, having teeth (OR 0.59) and dentures (OR 0.66) significantly decreased the rate of falls (P<0.05).

Conclusion

It was concluded that age, non-Malay ethnicity, functional decline, heart disease, and oral health significantly affected falls in dementia.

Sleep disturbances and risk of falls in older community-dwelling men: the outcomes of Sleep Disorders in Older Men (MrOS Sleep) Study

OBJECTIVES

To test the hypothesis that subjective and objective sleep disturbances are associated with risk of incident falls in older men.

DESIGN

The prospective observational MrOS Sleep Study.

SETTING

Six academic clinical centers in the United States.

PARTICIPANTS

Community-dwelling men aged 67 and older (mean 76) (n = 3,101).

MEASUREMENTS

Subjective sleep measurements included daytime sleepiness (Epworth Sleepiness Scale (ESS)), sleep quality (Pittsburgh Sleep Quality Index (PSQI)), and total sleep time (TST). Objective sleep measurements included actigraphic TST and sleep efficiency (an index of fragmentation) and sleep disordered breathing (measured using in-home polysomnography). Fall frequency during the subsequent year was ascertained three times per year using questionnaires. Recurrent falling was defined as having two or more falls in the subsequent year.

RESULTS

In multivariable-adjusted models, participants with excessive daytime sleepiness (ESS > 10) but not poor subjective sleep quality (PSQI > 5) had greater odds of experiencing two or more falls in the subsequent year (odds ratio (OR) = 1.52 95% confidence interval (CI) = 1.14-2.03). Based on actigraphic recordings, the odds of having recurrent falls was higher for men who slept 5 hours or less (OR = 1.79, 95% CI = 1.22-2.60) than for those who slept 7 to 8 hours. Actigraphically measured sleep efficiency was also associated with greater risk of falls, as was nocturnal hypoxemia (≥ 10% of sleep time with arterial oxygen saturation <90%; OR = 1.62, 95% CI = 1.17-2.24) but not apnea hypopnea index.

CONCLUSION

Subjective and objective sleep disturbances were associated with risk of falls in older men, independent of confounders.

Comorbidities and personal burden of urgency urinary incontinence: a systematic review

AIMS

Studies on the burden and comorbidities associated with urgency urinary incontinence (UUI) are difficult to compare, partly because of the evolution of definitions for lower urinary tract symptoms and the various instruments used to assess health-related quality of life (HRQL). This article summarises published evidence on comorbidities and the personal burden associated specifically with UUI to provide clinicians with a clear perspective on the impact of UUI on patients.

METHODS

A PubMed search was conducted using the terms: (urgency urinary incontinence OR urge incontinence OR mixed incontinence OR overactive bladder) AND (burden OR quality of life OR well-being OR depression OR mental health OR sexual health OR comorbid), with limits for English-language articles published between 1991 and 2011.

RESULTS

Of 1364 identified articles, data from 70 retained articles indicate that UUI is a bothersome condition that has a marked negative impact on HRQL, with the severity of UUI a predictor of HRQL. UUI is significantly associated with falls in elderly individuals, depression, urinary tract infections, increased body mass index, diabetes and deaths. The burden of UUI appears to be greater than that of stress urinary incontinence or overactive bladder symptoms without UUI. UUI adversely impacts physical and mental health, sexual function and work productivity.

CONCLUSIONS

UUI is associated with numerous comorbid conditions and inflicts a substantial personal burden on many aspects of patients' lives. Healthcare providers should discuss UUI with patients and be aware of the impact of UUI and its associated comorbidities on patients' lives.

Association between sleep disturbances and falls among the elderly: results from the German Cooperative Health Research in the Region of Augsburg-Age study

OBJECTIVE

We aimed to examine the association between various sleep disturbances and falls among older individuals from the general population while considering the influence of age and dizziness.

METHODS

Data were derived from the population-based cross-sectional KORA (Cooperative Health Research in the Region of Augsburg)-Age study, whereby information was conducted in standardized telephone interviews with 4127 men and women aged ⩾65years in 2008 and 2009. Unstratified and stratified (by age and dizziness) multivariable logistic regression model analyses were performed.

RESULTS

The multivariable analysis showed a marginally significant association between trouble staying asleep and ⩾1 fall in the previous year (odds ratio [OR], 1.23 [95% confidence interval (CI), 1.01-1.50]). This association was more pronounced in participants older than the age of 75years (OR, 1.58 [95% CI, 1.16-2.16]) and in individuals without dizziness (OR, 1.35 [95% CI, 1.04-1.76]). There was no association between daytime sleepiness and falls in the fully-adjusted models, but the odds of falls in the previous year in individuals older than the age of 75years were significantly higher for individuals with difficulty falling asleep. Although sleep duration was not associated with falls in multivariable analyses when stratified by dizziness, sleep duration of 9h daily was significantly associated with higher odds of experiencing at least one fall in the previous year.

CONCLUSIONS

Our study suggested that the positive relationship between a trend towards longer sleep duration, trouble falling and staying asleep, and falls is strongest in older individuals and in individuals who did not experience dizziness in the previous year.

Do continence management strategies reduce falls? a systematic review

Urinary incontinence is associated with increased fall risk, and fall prevention programs include recommendations to manage continence as one component of fall reduction. However, the evidence to support this recommendation is unclear. The aim of this study was to identify continence management interventions that are effective in decreasing falls. A systematic review of the literature was conducted. Studies were included if they evaluated the effect of any type of continence management strategy on falls in older adults. The included studies were assessed for quality, and data relating to participants, interventions and outcomes were extracted by two independent reviewers. Four articles met the inclusion criteria. Two studies were randomised controlled trials, one a retrospective cohort study and one an uncontrolled intervention study. Interventions included pharmacological agents, a toileting regime combined with physical activity and an individualised continence program. Only the study evaluating the combination of physical activity and prompted voiding found an effect on falls. It is surprising that there has been so little research into continence management interventions that include fall outcomes. A toileting regime combined with physical activity may reduce falls in residential care. There is a need for further studies investigating the impact of continence management on falls.

The effects of sleep quality, physical activity, and environmental quality on the risk of falls in dementia

OBJECTIVES

This study aimed to identify the effects of sleep quality, physical activity, environmental quality, age, ethnicity, sex differences, marital status, and educational level on the risk of falls in the elderly individuals with dementia.

METHODOLOGY

Data were derived from a group of 1210 Malaysian elderly individuals who were noninstitutionalized and demented. The multiple logistic regression model was applied to estimate the risk of falls in respondents.

RESULTS

Approximately the prevalence of falls was 17% among the individuals. The results of multiple logistic regression analysis revealed that age (odds ratio [OR] = 1.03), ethnicity (OR = 1.76), sleep quality (OR = 1.46), and environmental quality (OR = 0.62) significantly affected the risk of falls in individuals (P < .05). Furthermore, sex differences, marital status, educational level, and physical activity were not significant predictors of falls in samples (P > .05).

CONCLUSION

It was found that age, ethnic non-Malay, and sleep disruption increased the risk of falls in respondents, but high environmental quality reduced the risk of falls.

Lower urinary tract symptoms and falls risk among older women receiving home support: a prospective cohort study

Background

Although lower urinary tract symptoms have been associated with falls, few studies have been undertaken to understand this relationship in vulnerable community dwelling older adults. The purpose of this study was to describe the relationship over time of falls risk and lower urinary tract symptoms among community based older women receiving home support services.

Methods

A prospective cohort study which took place in an urban setting in western Canada. Participants were 100 older women receiving home care or residing in assisted living with home support services and were followed for six months. Demographic characteristics were collected at baseline, with the Timed Up and Go (TUG), International Consultation on Incontinence Questionnaire Female Lower Urinary Tract Symptoms (ICIQ-FLUTS), and self-report of falls collected at baseline, 3 and 6 months. Descriptive statistics were used to summarize demographic data. Differences between the three visits were analyzed using the Friedman test with post hoc analysis and associations between variables by the Spearman Rank-Order Correlation Coefficient.

Results

One hundred women initially enrolled; 88 and 75 remained at three months and six months. Mean age = 84.3 years; 91% reported at least one urinary symptom at baseline and 35% reported falling in the six months prior to enrollment; 15.9% reported falling between the baseline and three months and 14.6% between three and six months. Mean TUG scores at each time point indicated falls risk (27.21, 29.18 and 27.76 seconds). Significant correlations between TUG and ICIQ-FLUTS (r ₌ 0.33, p < .001; r ₌ 0.39, p < .001) as well as TUG and overactive bladder scores (r ₌ 0.25, p = .005; r ₌ 0.28, p < .008) were found at baseline and three months, but not six months.

Conclusions

The association of lower urinary tract symptoms and falls risk in this group of vulnerable community dwelling older women at baseline and three months has potential clinical relevance. Lack of correlation at six months may be due loss of less robust participants, illuminating the difficulty in following frailer groups over time. Further studies are needed to understand the contribution of urinary symptoms to falls risk, and clinicians should incorporate continence assessment within falls risk assessment.

Associação entre sintomas de insônia, cochilo diurno e quedas em idosos da comunidade

Essa pesquisa investigou associações entre sintomas de insônia, cochilo diurno, e quedas em idosos da comunidade. Estudo transversal de base populacional e amostra probabilística envolvendo 689 idosos da comunidade. O protocolo continha variáveis de autorrelato e de desempenho físico. Foi utilizada a análise de regressão logística univariada e multivariada, e o nível de significância estatística adotado foi de p < 0,05. A prevalência de sintomas de insônia e cochilo diurno foi de 49,9% (n = 339) e 62,8% (n = 432), respectivamente. Quatorze vírgula quatro porcento relataram uma única queda e 11,9% relataram quedas recorrentes. A ocorrência de quedas associou-se com sexo feminino (OR = 7,73; IC95%: 3,03-19,72), idade > 80 anos (OR = 3,48; IC95%: 1,54-7,85), cochilo diurno (OR = 2,24; IC95%: 1,24-4,05) e sintomas depressivos (OR = 1,98; IC95%: 1,11-3,53). A associação entre cochilo diurno e quedas replicam dados de pesquisa internacional. Identificar fatores de risco modificáveis pode auxiliar programas de prevenção de quedas.

Effect of sitting pause times on postural stability after supine-to-standing transfer in dimly lit environments

BACKGROUND AND PURPOSE

Falls are common and often take place in the home. Risk of fall increases if the environment is dimly lit. Longer sitting pause times, before standing, might improve postural stability after standing from a supine position. The purpose of this investigation was to measure the effects of sitting pause times on postural sway velocity immediately following a supine-to-standing transfer in a dimly lit room in older and younger adult women.

METHODS

Five women aged 65 to 70 years and 5 aged 23 to 30 years participated in the study. On each of 2 consecutive days, study participants lay on a mat table with their eyes closed for 45 minutes before performing a supine-to-standing transfer in a dimly lit room. Sitting pause times of 2 seconds and 30 seconds preceded the transfers.

RESULTS

Mean postural sway velocity for the whole sample and for younger and older groups was less after a 30-second pause time than that after a 2-second pause time (sample, P = .001; young, P = .019; old, P = .021). No significant difference in mean postural sway velocity was observed between the 2 groups (P > .05).

CONCLUSIONS

Total mean postural sway velocity was less when study participants performed a sitting pause of 30 seconds before standing in a dimly lit room. These results suggest that longer sitting pause times may provide improved adaptability to dimly lit environments contributing to improved postural stability.

Self-reported sleep duration and falls in older adults

Whether the association between sleep duration and accidental falls is independent of sleep quality is uncertain. It is also unclear if this association varies with age and sex among older adults. Data were collected through telephone interviews of 1542 community-dwelling individuals aged ≥68 years in Spain. Analyses were performed with logistic regression and adjusted for the main confounders, including lifestyle, health status, comorbidity and sleep quality, as measured by nighttime and daytime sleep complaints. Analyses were also stratified by age and sex. In total, 449 (29.1%) participants fell in the previous year; of these, 57.7% had one fall and 42.3% had recurrent (≥2) falls. As compared with those who usually slept 7-8 h, those sleeping ≥11 h were more likely to suffer recurrent falls [odds ratios (OR) 2.75; 95% confidence intervals (CI) 1.32-5.62]. In the stratified analysis, there was no association between sleep duration and falls in those aged ≤75 years and in men. In contrast, among those aged >75 years, the percentage of individuals with ≥1 falls was higher in those sleeping ≤5 h (OR 2.15; 95% CI 1.20-3.87) and ≥11 h (OR 2.34; 95% CI 1.17-4.68) than in those sleeping 7-8 h; also, women who slept ≥11 h were more likely to fall ≥1 times (OR 3.89; 95% CI 1.74-8.69). In conclusion, long sleep duration was associated with higher frequency of falls in older adults, even after adjustment for a wide range of sleep quality indicators. The association is clearer in women and the oldest adults. Assessment of sleep duration can help identify older adults who might benefit from interventions aimed at fall prevention.

Relação entre problemas do sono, desempenho funcional e ocorrência de quedas em idosos da comunidade

OBJETIVO: Esta revisão objetivou sistematizar estudos que avaliam a relação entre problemas do sono, desempenho funcional e ocorrência de quedas em idosos da comunidade. MÉTODO: Realizou-se revisão bibliográfica entre 21 e 30 de setembro de 2009, no idioma Inglês, com as seguintes palavras-chave: "sleep" AND "falls" AND "functional performance" AND "elderly". Foram utilizadas as bases de dados PubMed, Ageline e Scielo. Foram critérios de inclusão: artigos publicados de janeiro de 2006 a setembro de 2009; artigos completos; estudos transversais, retrospectivos, prospectivos; estudos realizados com idosos da comunidade. RESULTADOS: Foram encontrados 52 estudos, dos quais foram avaliados dez que preencheram os critérios de inclusão. CONCLUSÕES: Os estudos mostraram que os distúrbios do sono podem piorar o desempenho funcional, além de representarem fator de risco independente para quedas em idosos.
