Urinary incontinence in older community-dwelling women: the role of cognitive and physical function decline

Effects of using a mobile application on pelvic floor training in women with stress urinary incontinence: A randomized controlled clinical study

INTRODUCTION

Urinary incontinence (UI) is defined as any involuntary loss of urine that causes negative impacts on women's lives. Pelvic floor muscle training (PFMT) is considered to be "level A" of scientific evidence in the treatment of UI. Despite its efficacy, it is known that the effect of PFMT may depend on continuous adherence. Therefore, healthcare professionals are looking for alternatives to improve adherence in their patients. Healthcare has been innovating through mobile device apps.

OBJECTIVE

Thus, the objective of this study was to verify the effects of PFMT with the use of a mobile device app in incontinent women.

TRIAL DESIGN

This was a controlled, randomized clinical trial that occurred remotely.

METHODS

A total of 104 women with stress UI and/or mixed incontinence, over 18 years old, literate, with preserved cognitive capacity, with internet access and a mobile device with the Android system, participated in this study. They were randomly divided into two groups: The App group and the Booklet group, which underwent a PFMT protocol guided by a mobile app and a booklet, respectively. Both groups received daily reminders to perform the exercises. Before and after 12 weeks of intervention, it was evaluated using the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF) and the King's Health Questionnaire (KHQ).

RESULTS

Both groups showed improvements in the final ICIQ-SF score. However, superior results were shown for the Booklet group (App: pre: 11.5 [±3.8], post: 9.8 [±4.5]; Booklet: pre: 12.6 [±4.5], post: 7.4 [±4.3]; p = 0.03).

CONCLUSION

It was concluded that PFMT, with the use of a mobile app, is capable of reducing UI and the impact of UI, but it is not superior to training with the use of booklet instructions.

Efficacy of a Therapeutic Pelvic Yoga Program Versus a Physical Conditioning Program on Urinary Incontinence in Women : A Randomized Trial

BACKGROUND

Pelvic floor yoga has been recommended as a complementary treatment strategy for urinary incontinence (UI) in women, but evidence of its efficacy is lacking.

OBJECTIVE

To evaluate the effects of a therapeutic pelvic floor yoga program versus a nonspecific physical conditioning program on UI in women.

DESIGN

Randomized trial. (ClinicalTrials.gov: NCT03672461).

SETTING

Three study sites in California, United States.

PARTICIPANTS

Ambulatory women aged 45 years or older reporting daily urgency-, stress-, or mixed-type UI.

INTERVENTION

Twelve-week program of twice-weekly group instruction and once-weekly self-directed practice of pelvic floor-specific Hatha yoga techniques (pelvic yoga) versus equivalent-time instruction and practice of general skeletal muscle stretching and strengthening exercises (physical conditioning).

MEASUREMENTS

Total and type-specific UI frequency assessed by 3-day voiding diaries.

RESULTS

Among the 240 randomly assigned women (age range, 45 to 90 years), mean baseline UI frequency was 3.4 episodes per day (SD, 2.2), including 1.9 urgency-type episodes per day (SD, 1.9) and 1.4 stress-type episodes per day (SD, 1.7). Over a 12-week time period, total UI frequency (primary outcome) decreased by an average of 2.3 episodes per day with pelvic yoga and 1.9 episodes per day with physical conditioning (between-group difference of -0.3 episodes per day [95% CI, -0.7 to 0.0]). Urgency-type UI frequency decreased by 1.2 episodes per day in the pelvic yoga group and 1.0 episode per day in the physical conditioning group (between-group difference of -0.3 episodes per day [CI, -0.5 to 0.0]). Reductions in stress-type UI frequency did not differ between groups (-0.1 episodes per day [CI, -0.3 to 0.3]).

LIMITATION

No comparison to no treatment or other clinical UI treatments; conversion to videoconference-based intervention instruction during the COVID-19 pandemic.

CONCLUSION

A 12-week pelvic yoga program was not superior to a general muscle stretching and strengthening program in reducing clinically important UI in midlife and older women with daily UI.

The Correlation Between Comfort Level and Quality of Life in Female Patients With Urinary Incontinence: Structural Equation Modeling Approach

PURPOSE

The aim of this study was to develop a model to determine the correlation between comfort level and quality of life in women with UI.

DESIGN

Cross-sectional, descriptive correlational research design with causal modeling.

SUBJECTS AND SETTING

The study was conducted in the urology outpatient clinic of a university hospital in the Central Anatolia region of Turkey. The sample comprised 233 women admitted to the outpatient clinic between December 2017 and May 2018. Participants had a mean age of 52.5 (SD = 13.9) years.

METHODS

Data were collected using a researcher-designed Descriptive Characteristics Form, the Incontinence Quality of Life (I-QOL) form, the Urinary Incontinence and Frequency Comfort Questionnaire (UIFCQ), and the Short Form-36 (SF-36). Multivariate correlations were analyzed using structural equation modeling; an AMOS covariance-based structural equation model was developed.

RESULTS

The correlational pathway between I-QOL, UIFCQ, and SF-36 was statistically significant. As a result of the confirmed model, I-QOL scores were moderately correlated with SF-36 scores (r = .65, P = .001) and highly correlated with UIFCQ scores (r = .76, P = .001). Mean UIFCQ scores were moderately correlated with SF-36 scores (r = .66, P = .001). The structural equation modeling resulted in a model with a good fit.

CONCLUSIONS

The higher the comfort level, the higher the UI-specific and health-related quality of life. Risk factors related to UI should be monitored, and necessary training and counseling should be provided to eliminate this common problem.

Reducing Falls in Older Women with Urinary Incontinence

Urinary incontinence is common in older women and doubles the risk of falls in this population. The association between urinary incontinence, especially urgency urinary incontinence, and falls is multifactorial and likely the result of a complex interaction between physical, mental, social, and environmental factors. As a result of this multifactorial etiology and based on existing evidence, the integration of different fall prevention strategies including strength and resistance exercises, bladder training, and home hazard reduction have the potential to decrease the risk of falls in older women with urinary incontinence. Given the prevalence of urinary incontinence and the significant morbidity associated with falls, effective interventions to reduce fall risk in older women with urinary incontinence is of high public health significance.

Comorbidities of community-dwelling older adults with urinary incontinence: A scoping review

BACKGROUND

Identifying comorbidities is a critical first step to building clinical phenotypes to improve assessment, management, and outcomes.

OBJECTIVES

1) Identify relevant comorbidities of community-dwelling older adults with urinary incontinence, 2) provide insights about relationships between conditions.

METHODS

PubMed, Cumulative Index of Nursing and Allied Health Literature, and Embase were searched. Eligible studies had quantitative designs that analyzed urinary incontinence as the exposure or outcome variable. Critical appraisal was performed using the Joanna Briggs Institute Critical Appraisal Checklists.

RESULTS

Ten studies were included. Most studies had methodological weaknesses in the measurement of conditions. Comorbidities affecting the neurologic, cardiovascular, psychologic, respiratory, endocrine, genitourinary, and musculoskeletal systems were found to be associated with urinary incontinence.

CONCLUSION

Existing literature suggests that comorbidities and urinary incontinence are interrelated. Further research is needed to examine symptoms, shared mechanisms, and directionality of relationships to generate clinical phenotypes, evidence-based holistic care guidelines, and improve outcomes.

Overactive Bladder and Cognitive Impairment: The American Urogynecologic Society and Pelvic Floor Disorders Research Foundation State-of-the-Science Conference Summary Report

IMPORTANCE

Overactive bladder (OAB) is prevalent in older adults in whom management is complicated by comorbidities and greater vulnerability to the cognitive effects of antimuscarinic medications.

OBJECTIVES

The aim of this study is to provide a comprehensive evidence-based summary of the 2021 State-of-the-Science (SOS) conference and a multidisciplinary expert literature review on OAB and cognitive impairment.

STUDY DESIGN

The American Urogynecologic Society and the Pelvic Floor Disorders Research Foundation convened a 3-day collaborative conference. Experts from multidisciplinary fields examined cognitive function, higher neural control of the OAB patient, risk factors for cognitive impairment in older patients, cognitive effects of antimuscarinic medications for OAB treatment, OAB phenotyping, conservative and advanced OAB therapies, and the need for a multidisciplinary approach to person-centered treatment. Translational topics included the blood-brain barrier, purine metabolome, mechanotransduction, and gene therapy for OAB targets.

RESULTS

Research surrounding OAB treatment efficacy in cognitively impaired individuals is limited. Short- and long-term outcomes regarding antimuscarinic effects on cognition are mixed; however, greater anticholinergic burden and duration of use influence risk. Oxybutynin is most consistently associated with negative cognitive effects in short-term, prospective studies. Although data are limited, beta-adrenergic agonists do not appear to confer the same cognitive risk.

CONCLUSIONS

The 2021 SOS summary report provides a comprehensive review of the fundamental, translational, and clinical research on OAB with emphasis on cognitive impairment risks to antimuscarinic medications. Duration of use and antimuscarinic type, specifically oxybutynin when examining OAB treatments, appears to have the most cognitive impact; however, conclusions are limited by the primarily cognitively intact population studied. Given current evidence, it appears prudent to minimize anticholinergic burden by emphasizing nonantimuscarinic therapeutic regimens in the older population and/or those with cognitive impairment.

Is There an Association between Norton Scale and Cognitive Impairment in Hip Fractured Elderly Patients?

INTRODUCTION

Geriatric assessment as an integrative part of assessment is a composite of a large number of scales. Sometimes it is difficult to transfer all of them. The Norton Scale Score (NSS) assesses the degree of risk to develop bedsores. In previous studies, a correlation between Norton Scale and function was found. A correlation between Norton Scale and cognitive assessments was not evaluated yet. The aim of this study was to determine if there is an association between Norton Scale Score and cognitive impairment. This association can further facilitate geriatric assessment in frail older patients, especially in older patients with communicative difficulties.

METHODS

We have performed an observational cohort study which included hip fractured older patients consecutively admitted to the rehabilitation ward of the Shmuel Harofe Geriatric Medical Center. The collected data included demographic data and data on chronic illnesses. Results of cognitive status assessment (Mini-Mental State Examination - MMSE) and Norton Scale assessment were received from the computerized patients' charts. We evaluated the association between these 2 scales.

RESULTS

The study included 224 consecutive hip fracture patients with a mean age of 81.78 ± 7.19 years. Norton scores at admission, age, education, and previous stroke emerged as the only statistically significant parameters differing between those with cognitive decline and those without it. After adjusting for confounding variables, lower Norton scores at admission (OR 1.303, CI: 1.097-1.548, p = 0.003) were associated with an increased risk finding for cognitive impairment.

CONCLUSION

Our findings suggest that there is an association between Norton Scale Scores and cognitive impairment. Norton score parameters, under certain circumstances, such as speech and other communication difficulties, can be used as a proxy measure for MMSE to indicate cognitive impairment. These findings can be even more helpful in the present time of "COVID-19," when we have to evaluate older patients with facial masks and other defensive suits.

Prevalence and Risk Factors of Urinary Incontinence Among Elderly Adults in Rural China: A Cross-Sectional Survey

PURPOSE

The purpose of this study was to explore the prevalence of urinary incontinence (UI) and several subtypes: (stress, urge, and mixed UI) and the influence of multiple factors on the likelihood of UI.

DESIGN

Epidemiological study based on cross-sectional data collection.

SUBJECTS AND SETTING

The sample comprised 1279 inhabitants 65 years and older residing in 10 villages randomly selected from the Shanxi province, located in North China.

METHODS

The presence and types of UI were assessed using the International Consultation of Incontinence Questionnaire-Short Form. Sociodemographic parameters were also recorded, along with data on lifestyle, bowel function, and medical conditions. The Activity of Daily Living Scale and Mini-Mental State Examination instruments were used to evaluate physical and cognitive functions, respectively. A multivariate logistic regression model with the backward method was employed to identify factors associated with UI.

RESULTS

The prevalence of any UI among the rural Chinese elderly 65 years and older was 46.8%, with a female predominance (56.3% in females vs 35.0% in males). The most common incontinence subtype in women was mixed UI (n = 170, 24.0%), followed by stress UI (n = 131, 18.5%) and urge UI (n = 97, 13.7%). The most prevalent form of UI in males was urge UI (n = 190, 33.2%), followed by stress UI (n = 5, 0.9%) and mixed UI (n = 5, 0.9%). Less than one quarter of respondents (17%, n = 102) of participants with UI had consulted a doctor. Multivariate analysis found that poorer physical function, poor quality of sleep, and fecal incontinence were common factors associated with UI in both women and men. In women, higher body mass index and constipation were also independent correlates, as were poor vision and heart disease in men. Poorer physical function was associated with all UI subtypes. For female stress UI, poorer cognitive status, tea drinking, and hypertension also emerged as independent risk factors. Heart disease was an independent risk factor in both female and male urge UI; as was consumption of a non-plant-based diet for female mixed and urge UI; nonfarmer and traumatic brain injury for female urge UI; and poor vision and fecal incontinence in male urge UI.

CONCLUSIONS

Chinese rural citizens showed a high UI prevalence, but only a small proportion had consulted a health care provider. Physical function decline was the most important contributor to UI among participants. Individualized intervention programs targeting modifiable risk factors among high-risk populations should be developed.

A Review of Aging and the Lower Urinary Tract: The Future of Urology

Lower urinary tract symptoms (LUTS) are common among elderly people, with significant effects on individuals, caregivers, and the wider health care system. As the elderly population with multiple comorbidities is increasing, the burden of LUTS will increase. This review describes the demographic trends in the aging society, changes in lower urinary tract function with aging, and deterioration of physical and cognitive function in aging, as well as what has been done regarding geriatric urology and what urologists should do to meet the health care needs of the aging population. Frailty and dementia are unmissable factors in the evaluation of elderly patients. Numerous reports have described associations between LUTS and frailty and between LUTS and dementia. Urologists must be aware of the multiplex physical, cognitive, and social characteristics of elderly people. Maintaining a geriatric viewpoint in the diagnosis, treatment, and management of elderly individuals with LUTS will fulfill the unmet needs of elderly people. It is also essential to discuss the treatment and management goals of LUTS with patients and caregivers. Active case identification, appropriate evaluations of LUTS and comorbidities, and a multidisciplinary approach with other health-care professionals are recommended for better treatment and management.

Urinary incontinence onset predictors in community-dwelling older women: A prospective cohort study

AIM

We aimed to investigate whether physical function was associated with urinary incontinence (UI) onset in community-dwelling older Japanese women.

METHODS

This was a 4-year prospective cohort study. After excluding participants with UI and missing data in the baseline survey, we included 890 participants in the analyses. Physical function including grip strength, maximal walking speed, knee extension strength, single-leg balance, and timed up and go (TUG) were measured. The primary outcome was the onset of all UI and different types of UI (urge, stress and mixed) based on the questionnaire survey. Binary logistic regression analysis was applied to calculate the adjusted odds ratios and 95% confidence intervals for the association between physical function and the risk of all UI and different types of UI incident.

RESULTS

Among the 890 participants, 221 (25%) developed UI during the 4-year follow-up. After adjusting for confounders, better knee extension strength, maximal walking speed and TUG were significantly associated with a lower risk of all UI and urge UI onset, and better single-leg balance and TUG were significantly associated with a lower risk of mixed UI onset (P for trend <0.05). No significant association was found between physical function and the risk of stress UI onset.

CONCLUSIONS

This study confirmed that better lower extremity physical function is associated with lower risk of urge and mixed UI onset, indicating that exercise programs focusing on maintaining and improving lower extremity physical function may be useful for reducing such events among older women. Geriatr Gerontol Int 2021; 21: 178-184.

Prevalence and Associated Factors of Fecal Incontinence and Double Incontinence among Rural Elderly in North China

Fecal and double incontinence are known to be more prevalent among the rural elderly. Yet, there have been few studies on their epidemic condition among Chinese rural elders. This study estimated the prevalence and correlates of fecal and double incontinence in rural elderly aged 65 years and over in North China. A multisite cross-sectional survey was conducted in 10 villages, yielding a sampling frame of 1250 residents. Fecal and urinary incontinence assessments were based on the self-reported bowel health questionnaire and the International Consultation on Incontinence Questionnaire-Short Form, respectively. The concomitant presence of fecal and urinary incontinence in the same subject was defined as double incontinence. The prevalence of fecal and double incontinence was 12.3% and 9.3%, respectively. Factors associated with fecal incontinence included urinary incontinence, lack of social interaction, traumatic brain injury, cerebrovascular disease, and poverty. Physical activities of daily living dependence, traumatic brain injury, lack of social interaction, and poor sleep quality were associated with higher odds of having double incontinence, whereas tea consumption was correlated with lower odds. Individualized intervention programs should be developed targeting associated factors and high-risk populations. These intervention programs should be integrated into existing public health services for the rural elderly to facilitate appropriate prevention and management of incontinence.

Physical performance measures in older women with urinary incontinence: pelvic floor disorder or geriatric syndrome?

Objective:

To evaluate physical performance measures of mobility and functional impairments and assess their association with urinary incontinence (UI) severity and impact on quality of life among older women with UI.

Methods:

In a cross-sectional pilot study, 20 women aged ≥ 70 years with UI completed UI questionnaires (Global Impression of Severity, Incontinence Impact Questionnaire (IIQ-7)) and functional status evaluation. Functional status evaluation included the Modified Physical Performance Test (MPPT; range 0–36), Short Physical Performance Battery (SPPB; range 0–12), and other physical performance measures (e.g., Timed Up and Go [TUG]). MPPT and SPPB scores <32 and <10, respectively, indicated impaired mobility and function. Descriptive statistics and spearman correlation coefficients evaluated study variables and associations between UI and physical performance measures.

Results:

Women were 76.6±4.7 years old with mean body mass index 33.5±9.0 kg/m². Mixed UI was the most prevalent (n=17; 85%), and 14 (70%) participants rated their UI as moderate or severe. Low MPPT (<32) and SPPB (<10) scores were present in 65% (n=13) and 35% (n=7) of participants, respectively. Lower MPPT score (r=−0.46; P=0.04) and worse TUG performance (r=0.50; P=0.03) were associated with greater UI impact on quality of life based on IIQ-7. SPPB did not correlate (P>0.05) with UI measures.

Conclusions:

Mobility and functional impairments are common among older women with UI. Associations between MPPT score, TUG performance with UI impact on quality of life suggest these physical performance measures could be markers of mobility and functional impairments in future research on UI in older women.

Further research in utility of physical performance measures as markers of mobility and functional impairments in older women with urinary incontinence is warranted.

Continence: Bowel and Bladder and Physical Function Decline in Women

Purpose of review

The purpose of this article is to review the various forms of incontinence, highlight their impact on older women, and to explore current literature regarding the link between physical activity, physical function, and incontinence.

Recent findings

Both urinary and fecal incontinence become more prevalent with age, and are associated with significant morbidity. In parallel, there is a well-established decline in physical function that occurs with age. Furthermore, incontinence has a bidirectional relationship with physical function decline. Given the known link between increasing physical activity and preserved physical function, there is an emerging body of literature seeking to determine whether increases in physical activity may also improve incontinence outcomes. We review some recent data on this topic.

Summary

Continence and physical function are two closely linked entities. Further research is needed to determine whether interventions that increase physical activity might result in improved continence outcomes.

Vitamin D intake and the 10-year risk of urgency urinary incontinence in women

Evidence indicates that higher serum 25-hydroxy vitamin D levels may be associated with decreased prevalence of urgency urinary incontinence (UI), but the impact of vitamin D consumption on development of urgency and mixed UI is unclear. The objective was to assess whether greater vitamin D intake was associated with decreased risk of incident urgency and mixed UI over 10 years using 2 large prospective cohorts of middle-aged and older women. We analyzed 38,101 women from the Nurses' Health Study I (NHS I) and 35,190 women from NHS II who were free of UI at baseline. We followed incident UI, defined as new UI occurring at least monthly, separately by subtype (urgency, mixed, stress UI), from 2002-2012. We categorized vitamin D intake from supplements and diet. We estimated relative risk for developing UI according to vitamin D intake using Cox-proportional hazard models with adjustment for covariates. Median vitamin D intake was 580IU in the older women in NHS I (age range 56-71 at baseline) and 487IU in middle-aged women in NHS II (age range 40-57). Among women taking ≥1000IU of vitamin D, median intake in the older women was 1252IU and 1202IU in the middle-aged women. Among the older women, we found no relation of vitamin D intake to risk of developing UI, across all UI subtypes. In multivariable-adjusted analysis for middle-aged women, the relative risk of developing mixed UI among women taking >1000IU was 0.79 (0.63, 0.99) and for urgency UI was 0.88 (0.71, 1.07), versus <200IU. Risks of developing stress UI were not related to vitamin D intake categories. Overall, we did not find a relationship between vitamin D intake and UI incidence in middle-aged and older women; however, the reported intake was moderate.

Exploring a Path Model of Cognitive Impairment, Functional Disability, and Incontinence Among Male Veteran Home Residents in Southern Taiwan

Most studies focusing on only one directional effect among cognitive health, physical function, and incontinence may miss potential paths. This study aimed to determine the pathway by analyzing the bidirectional effects of exposure (X) on outcome (Y) and explore the mediating effect (M) between X and Y. Secondary data analyses were performed in this study. The original data were collected from August to October 2013 in one VH in Tainan, Taiwan, and the final sample size was 144 older male veterans. Path analysis was performed to test the pathway sequence X → M → Y among the three outcome variables. Approximately 80% of the veterans were aged 81 or older, approximately 42% had a functional disability, 26% had cognitive impairment, and 20% had incontinence. The relationships between functional disability and incontinence and between functional disability and cognition impairment were bidirectional, and functional disability played a key mediating role in the relationship between cognitive impairment and incontinence. Physical more than cognitive training in order to improve or at least stabilize functional performance could be a way to prevent or reduce the process of developing incontinence.

Is urinary incontinence associated with sedentary behaviour in older women? Analysis of data from the National Health and Nutrition Examination Survey

BACKGROUND

Urinary incontinence (UI) is a common geriatric syndrome associated with physical and cognitive impairments. The association between type of UI and sedentary behaviour (SB) has not been explored.

AIM

To determine association between moderate-severe UI, or any stress UI (SUI) or any urgency UI (UUI) and SB in community-dwelling older women.

METHODS

Women aged 60 and over from the 2005-2006 cycle of the National Health and Nutrition Examination Survey (NHANES) with objectively measured (accelerometer) and self-reported SB and UI data were selected. Multivariate models exploring association between moderate-severe UI and SB, or SUI and SB, or UUI and SB were analysed using logistic regression adjusted for factors associated with UI.

RESULTS

In the overall sample of 459 older women, 23.5% reported moderate-severe UI, 50.5% reported any SUI and 41.4% reported any UUI. In bivariate analysis objectively measured proportion of time in SB was associated with moderate-severe UI and UUI (p = 0.014 and p = 0.047) but not SUI. Average duration of SB bouts in those with moderate-severe UI or any SUI was no longer than older women reporting no continence issues, but it was significantly (19%) longer in older women with any UUI (mean difference 3.2 minutes; p = 0.001). Self-reported SB variables were not associated with any type of UI. Multivariate analysis showed an association between UUI and a longer average duration of SB bouts (OR = 1.05, 95% CI = 1.01-1.09, p = 0.006) but no association with moderate-severe UI or SUI.

CONCLUSION

UUI was significantly associated with increased average duration of SB bouts in community-dwelling older women. The importance of objective measurement of SB is highlighted and suggests that decreasing time in prolonged sitting may be a target intervention to reduce UUI. Future studies are required to further explore the association between SB and incontinence.

Physical Activity Patterns and Sedentary Behavior in Older Women With Urinary Incontinence: an Accelerometer-based Study

PURPOSE

Objective physical activity data for women with urinary incontinence are lacking. We investigated the relationship between physical activity, sedentary behavior, and the severity of urinary symptoms in older community-dwelling women with urinary incontinence using accelerometers.

MATERIALS AND METHODS

This is a secondary analysis of a study that measured physical activity (step count, moderate-to-vigorous physical activity time) and sedentary behavior (percentage of sedentary time, number of sedentary bouts per day) using a triaxial accelerometer in older community-dwelling adult women not actively seeking treatment of their urinary symptoms. The relationship between urinary symptoms and physical activity variables was measured using linear regression.

RESULTS

Our cohort of 35 community-dwelling women (median, age, 71 years) demonstrated low physical activity (median daily step count, 2168; range, 687-5205) and high sedentary behavior (median percentage of sedentary time, 74%; range, 54%-89%). Low step count was significantly associated with nocturia (P = 0.02). Shorter duration of moderate-to-vigorous physical activity time was significantly associated with nocturia (P = 0.001), nocturnal enuresis (P = 0.04), and greater use of incontinence products (P = 0.04). Greater percentage of time spent in sedentary behavior was also significantly associated with nocturia (P = 0.016).

CONCLUSIONS

Low levels of physical activity are associated with greater nocturia and nocturnal enuresis. Sedentary behavior is a new construct that may be associated with lower urinary tract symptoms. Physical activity and sedentary behavior represent potential new targets for treating nocturnal urinary tract symptoms.

ELECtric Tibial nerve stimulation to Reduce Incontinence in Care homes: protocol for the ELECTRIC randomised trial

BACKGROUND

Urinary incontinence (UI) is highly prevalent in nursing and residential care homes (CHs) and profoundly impacts on residents' dignity and quality of life. CHs predominantly use absorbent pads to contain UI rather than actively treat the condition. Transcutaneous posterior tibial nerve stimulation (TPTNS) is a non-invasive, safe and low-cost intervention with demonstrated effectiveness for reducing UI in adults. However, the effectiveness of TPTNS to treat UI in older adults living in CHs is not known. The ELECTRIC trial aims to establish if a programme of TPTNS is a clinically effective treatment for UI in CH residents and investigate the associated costs and consequences.

METHODS

This is a pragmatic, multicentre, placebo-controlled, randomised parallel-group trial comparing the effectiveness of TPTNS (target n = 250) with sham stimulation (target n = 250) in reducing volume of UI in CH residents. CH residents (men and women) with self- or staff-reported UI of more than once per week are eligible to take part, including those with cognitive impairment. Outcomes will be measured at 6, 12 and 18 weeks post randomisation using the following measures: 24-h Pad Weight Tests, post void residual urine (bladder scans), Patient Perception of Bladder Condition, Minnesota Toileting Skills Questionnaire and Dementia Quality of Life. Economic evaluation based on a bespoke Resource Use Questionnaire will assess the costs of providing a programme of TPTNS. A concurrent process evaluation will investigate fidelity to the intervention and influencing factors, and qualitative interviews will explore the experiences of TPTNS from the perspective of CH residents, family members, CH staff and managers.

DISCUSSION

TPTNS is a non-invasive intervention that has demonstrated effectiveness in reducing UI in adults. The ELECTRIC trial will involve CH staff delivering TPTNS to residents and establish whether TPTNS is more effective than sham stimulation for reducing the volume of UI in CH residents. Should TPTNS be shown to be an effective and acceptable treatment for UI in older adults in CHs, it will provide a safe, low-cost and dignified alternative to the current standard approach of containment and medication.

Characteristics of Lower Limb Muscle Strength, Balance, Mobility, and Function in Older Women with Urge and Mixed Urinary Incontinence: An Observational Pilot Study

Purpose: After the age of 65, urinary incontinence (UI) occurs in one of every two women. A positive correlation between falls and urgency UI (UUI) or mixed UI (MUI) has also been identified. However, lower extremity impairments in older women with UUI or MUI have not been thoroughly investigated. The primary goal of this study was to compare lower limb strength, balance, mobility, and function in older women with and without UUI or MUI. The secondary goal was to evaluate the association between these measurements and UI severity. Method: A total of 40 older women with and without UUI or MUI completed standardized tests for lower limb strength (knee flexor or extensor dynamometry, 30-second sit-to-stand test), balance (single-leg stance test, Four Square Step Test, Activities-specific Balance Confidence questionnaire), mobility (10-metre walk test, 6-minute walk test), and function (Human Activity Profile questionnaire, 12-Item Short Form Health Survey). Results: Significant differences in balance and mobility were observed between the two groups. Women with UI had shorter single-leg stance times, lower balance confidence scores, and slower gait speeds. Conclusions: The results from this pilot study suggest that high-functioning older women with UUI or MUI have balance and mobility impairments. More studies are needed to confirm these results. By reporting power calculations for sample size, this pilot study provides a useful basis on which to design and conduct larger studies.

Achieving self-management goals among low income older adults with functional limitations

Although self-management interventions can improve symptoms and disease among older adults, there is a dearth of literature on how self-management behaviors may improve factors related to the older adults' physical function. To fill this gap in the literature, we describe the patient-directed self-management goals in nursing visits that relate to physical function as part of a multi-component program. We analyze the self-management goals and outcomes of 367 low- income older adults with functional limitations who participated in the CAPABLE program: a program to reduce the health effects of impaired physical function in low-income older adults. We focus on the following self-management goals that participants chose with the nurses: pain management, depressive symptoms, incontinence, fall prevention, and communication with healthcare providers. The majority of participants chose pain (50%) or fall prevention (51%) as goals and partially or fully met their goals. Improvements across these areas may lead to improved physical function.

Urinary Incontinence Is Associated With Physical Performance Decline in Community-Dwelling Older Women: Results From the International Mobility in Aging Study

Objective: The objective of this study is to evaluate the influence of urinary incontinence (UI) on physical performance. Method: In prospective analyses from the International Mobility in Aging Study (IMIAS), 915 women (65-74 years) from Canada, Colombia, Albania, and Brazil were evaluated in relation to self-reported UI (past week) and physical performance (Short Physical Performance Battery [SPPB]), with reevaluation after 2 years. Linear mixed models examined the influence of UI on SPPB, adjusted by covariates (age, study site, education, income sufficiency, body mass index [BMI] and parity). Results: Women reporting some UI presented lower SPPB mean (β = -0.41, p = .009) and a greater reduction (β = -0.53, p = .001) over 2 years than those reporting no UI. Discussion: Compared with no reported UI, some UI was associated with worse and more pronounced declines in physical performance over 2 years. This study highlights the importance of practices to reduce UI to contribute to healthier aging.

Health literacy, cognition, and urinary incontinence among geriatric inpatients discharged to skilled nursing facilities

AIMS

To investigate the association between health literacy and cognition and nursing and patient-reported incontinence in a geriatric inpatient population transitioning to skilled nursing facilities (SNF).

METHODS

Health literacy, depression, and cognition were assessed via the Brief Health Literacy Screen (BHLS), Geriatric Depression Scale 5-item (GDS) and Brief Interview for Mental Status (BIMS), respectively. Multivariable logistic regression assessed the association between BHLS score and incontinence by: (1) nursing-reported urinary incontinence during hospitalization; and (2) patient self-reported "bladder accidents" in the post-enrollment study interview.

RESULTS

A total of 1556 hospitalized patients aged 65 and older met inclusion criteria, of whom 922 (59.3%) were women and 1480 had available BHLS scores. A total of 464 (29.8%) and 515 (33.1%) patients had nursing-reported and self-reported urinary incontinence, respectively. Nursing-reported incontinence was significantly associated with lower BHLS (ie, poorer health literacy) (aOR 0.93, 95%CI 0.89-0.99) and BIMS (ie, poorer cognition) (aOR 0.90, 95%CI 0.83-0.97) scores and need for assistance with toileting (aOR 7.08, 95%CI 2.16-23.21). Patient-reported incontinence was significantly associated with female sex (aOR 1.62, 95%CI 1.19-2.21), increased GDS score (ie, greater likelihood of depression) (aOR 1.22, 95%CI 1.10-1.36) and need for assistance with toileting (aOR 2.46, 95%CI 1.26-4.79).

CONCLUSIONS

Poorer health literacy and cognition are independently associated with an increased likelihood of nursing-reported urinary incontinence among geriatric inpatients transitioning to SNF. Practitioners should consider assessment of health literacy and cognition in frail patients at risk for urinary incontinence and that patient and nursing assessment may be required to capture the diagnosis.

Relationship between aerobic capacity and pelvic floor muscles function: a cross-sectional study

The objective of this study was to evaluate the relationship between aerobic capacity and pelvic floor muscles (PFM) function in adult women. Women aged 18 or over and without urinary dysfunction or other chronic diseases were eligible to participate. They completed the habitual physical activity (HPA) questionnaire, underwent a PFM functional evaluation by palpation and perineometry, and performed a submaximal (between 75 and 85% of maximum heart rate) cardiopulmonary exercise (CPX) test to determine the ventilatory anaerobic threshold (VAT). Forty-one women were included (35±16 years, 75% physically active, 17% very active, and 8% sedentary and 17% presented grade 1 PFM contraction, 31.8% grade 2, 26.8% grade 3, and 24.4% grade 4, according to the modified Oxford Scale). The average PFM contraction pressure obtained by perineometer was 53±26 cmH2O and the average oxygen consumption at VAT (VO2VAT) obtained from CPX was 14±2 mL·kg-1·min-1. Significant correlations were found between PFM contraction pressure and VO2VAT (r=0.55; P<0.001); between PFM contraction pressure and HPA score (r=0.38; P=0.02); between age and VO2VAT (r=-0.25; P=0.049); and between VO2VAT and HPA score (r=0.36; P=0.02). An age-adjusted multiple linear regression equation (R2=0.32) was derived to estimate VO2VAT from the contraction value obtained by perineometer, so that the PFM contraction pressure was able to predict VO2VAT. The equation was validated using data from another group of 20 healthy women (33±12 years; PFM contraction: 49±23 cmH2O) and no significant difference was found between actual VO2VAT and predicted VO2VAT (13.1±1.9 vs 13.8±2.0 mL·kg-1·min-1). In conclusion, PFM function is associated with aerobic capacity in healthy women and PFM contraction pressure may be used to estimate VO2VAT in this population.

Incontinence and Nocturia in Older Adults After Hip Fracture: Analysis of a Secondary Outcome for a Parallel Group, Randomized Controlled Trial

Objective: To test the effect of a follow-up clinic on urinary incontinence (UI) and nocturia among older adults with hip fracture. Method: Fifty-three older adults (≥65 years) 3 to 12 months following hip fracture were enrolled and randomized to receive usual care plus the intervention (B4), or usual care (UC) only. The B4 group received management by health professionals, with need-based referrals. UI, nocturia, and quality of life were measured with questionnaires at baseline, 6 months, and 12 months. Results: There were 48 participants included in this analysis, and at baseline, 44% of study participants self-reported UI. At final assessment, six out of 24 B4 participants and 12 out of 24 UC participants reported UI. Four out of five study participants reported nocturia at baseline; this did not decrease during the study. Discussion: Following hip fracture, many older adults report UI and most report nocturia. Health professionals should be aware of the high occurrence of urinary symptoms among older adults post hip fracture.

Noctural Enuresis as a Risk Factor for Falls in Older Community Dwelling Women with Urinary Incontinence

PURPOSE

We determined the association of urinary symptoms with fall risk and physical limitations in older community dwelling women with urinary incontinence.

MATERIALS AND METHODS

We performed an in-depth assessment of daytime and nighttime urinary symptoms, fall risk, physical function, physical performance tests and mental function in older community dwelling women with urinary incontinence who had not sought care for urinary symptoms. All assessments were performed in participant homes. We used univariable and multivariable linear regression to examine the relationship of urinary symptoms to fall risk, physical function and physical performance.

RESULTS

Of 37 women with a mean ± SD age of 74 ± 8.4 years who had urinary incontinence 48% were at high risk for falls. Nocturnal enuresis was reported by 50% of the women. Increased fall risk was associated with increasing frequency of nocturnal enuresis (p = 0.04), worse lower limb function (p <0.001), worse upper limb function (p <0.0001) and worse performance on a composite physical performance test of strength, gait and balance (p = 0.02). Women with nocturnal enuresis had significantly lower physical performance test scores than women without nocturnal enuresis (median 7, range 0 to 11 vs 9, range 1 to 12, p = 0.04). In a multivariable regression model including age, nocturnal enuresis episodes and physical function only physical function was associated with an increased fall risk (p <0.0001).

CONCLUSIONS

Nocturnal enuresis is common in older community dwelling women with urinary incontinence. It may serve as a marker of fall risk even in women who do not seek care for urinary symptoms. Interventions targeting upper and lower body physical function could potentially decrease the risk of falls in older women with urinary incontinence.

Association between objectively measured sleep quality and physical function among community-dwelling oldest old Japanese: A cross-sectional study

AIM

The present study examined the association between objective measures of sleep quality and performance-based measures of physical function in community-dwelling oldest old Japanese.

METHODS

This cross-sectional study included 207 community-dwelling adults aged 80 years or older (92 men, 115 women; age 83.5 ± 2.6 years [range 80-95 years]). Participants wore an accelerometer (ActiGraph GT3X+) on their non-dominant wrist for 24 h per day over seven consecutive nights. Sleep parameters included total sleep time, sleep efficiency and wake after sleep onset during the night for a week. Performance-based physical function measures were handgrip strength, knee extension strength, and usual and maximum walking speeds. Multivariable linear regression was carried out to determine the associations between weekly sleep parameter averages and physical function measures.

RESULTS

Approximately 24% of participants had a total sleep time of less than 6 h a night, and 13% had greater than 8 h a night. Overall, average daily physical activity was 1771.8 ± 520.6 (counts/min/day). In multiple linear regression, sleep efficiency and wake after sleep onset were significantly associated with maximum walking speed (β = 0.277; 95% confidence interval [CI] 0.103 to 0.351 and β = -0.214; 95% CI -0.339 to -0.082, respectively) and usual walking speed (β = 0.200, 95% CI 0.035 to 0.305 and β = -0.174; 95% CI -0.341 to -0.064, respectively), after adjusting for potential confounding factors including daily physical activity. Both sleep qualities were also independently associated with knee extension strength. However, wake after sleep onset was not associated with handgrip strength.

CONCLUSION

Objectively measured sleep quality was associated with physical function in the oldest old. Further research is required to identify the temporality of associations between sleep and physical function.

Association of urinary incontinence with impaired functional status among older people living in a long-term care setting

AIM

To examine the association between functional status and urinary incontinence.

METHODS

A total of 27 participants with urinary incontinence and 50 participants without urinary incontinence were analyzed at a long-term care setting in Pingtung County, Taiwan, in 2011. The recruitment criteria were age older than 65 years, ability to communicate with the researcher, agreement to participate in the present study and potential ability to complete at least one measurement of functional status. Urinary incontinence was defined as urine leakage at least once a week during the past 4 weeks, whereas functional status was assessed by the body composition (body mass index and waist circumference), upper body strength (grasp test), lower body strength (30-s and 5-times chair stand test), upper body flexibility (back scratch test), lower body flexibility (chair sit-and-reach test) and agility/dynamic balance (8-ft up-and-go test).

RESULTS

In univariate analyses, performances on the tests of 5-time chair stand, 30-s chair stand, 8-ft up-and-go, chair sit-and-reach, and grasp were significantly different between the participants with and without urinary incontinence (all P < 0.05). However, after multiple logistical regression adjusting sex, age and chronic illnesses, just two tests, 8-ft up-and-go and chair sit-and-reach, were independent predictors of urinary incontinence.

CONCLUSION

Poor performance on the tests of 8-ft up-and-go and chair sit-and-reach were the predominated risk factors of urinary incontinence. Further studies regarding how to improve the functional status, especially focusing on the function of the lower body, might be required in order to enhance continence care.

Glycemic control and urinary incontinence in women with diabetes mellitus

BACKGROUND

Although many studies have shown that diabetes increases the risk for urinary incontinence, it is unclear whether poor glycemic control in women with diabetes is associated with incontinence. This study aims to determine the relationship between the hemoglobin A1c (HbA1c) level and urinary incontinence in a large, diverse cohort of older women.

METHODS

We examined 6026 older women who responded to a survey (62% response rate) and were enrolled in the Diabetes and Aging Study, an ethnically stratified random sample of patients with diabetes enrolled in Kaiser Permanente Northern California. Our primary independent variable was the mean of all HbA1c measurements in the year preceding the survey. Outcomes included the presence/absence of incontinence and limitations in daily activities due to incontinence. We used modified Poisson regression and ordinal logistic regression models to account for age, race, body mass index, parity, diabetes treatment, duration of diabetes, and comorbidity.

RESULTS

Sixty-five percent of women reported incontinence (mean age 59±10 years). After adjustment, HbA1c levels were not associated with the presence or absence of incontinence. However, among women reporting incontinence, HbA1c ≥9% was associated with more limitations due to incontinence than HbA1c <6% (adjusted odds ratio 1.67, 95% confidence interval: 1.09-2.57).

CONCLUSION

In this cross-sectional analysis, HbA1c level is not associated with the presence or absence of incontinence. However, for women with incontinence, poor glycemic control (HbA1c ≥9%) is associated with more limitations in daily activities due to incontinence. Longitudinal studies are needed to determine whether improving glycemic control to HbA1c <9% leads to fewer limitations in daily activities due to incontinence.

Mobility impairment is associated with urge but not stress urinary incontinence in community-dwelling older women: results from the Ossébo study

OBJECTIVE

To assess the association between functional limitations related to mobility and urinary incontinence (UI) in elderly women.

DESIGN

An observational cross-sectional study.

SETTING

Nine 'balance' workshops in France.

POPULATION

A total of 1942 community-dwelling women aged 75-85 years, who were invited, based on voter registration lists, to a 'balance assessment'.

METHODS

Mobility and balance test results for incontinent women were compared with those for continent women according to the severity and type of incontinence.

MAIN OUTCOME MEASURES

Data on UI were collected using a self-administered questionnaire (International Consultation on Incontinence Questionnaire-Short Form). Motor-related physical abilities were assessed using standardised balance and functional gait tests.

RESULTS

Forty-two per cent of women had involuntary urine leakage, with daily leaks in 57% of them; 24% had stress UI, 31% had urge UI, and 37% had mixed UI. Results for each functional test were poorer for women with UI and the limitation was more pronounced when the incontinence was severe. Multivariate logistic regression analyses showed that balance and gait impairments were significantly and independently associated with urge UI (walking speed, lower versus higher quartile, odds ratio (OR) 2.2; 95% confidence interval (95% CI) 1.4-3.5; walking balance, unable versus able to do four tandem steps (OR 1.6; 95% CI 1.2-2.2) but not with stress UI.

CONCLUSIONS

In this large population of older women living at home, there was a strong association between limitation of motor and balance skills and UI, which was proportional to the severity of incontinence and related specifically to urge incontinence. These results offer new perspectives on the prevention and treatment of urge incontinence in elderly women.

Sociodemographic and health indicators of older women with urinary incontinence: 2010 National Survey of Residential Care Facilities

OBJECTIVES

To describe the relationship between sociodemographic characteristics, health status, and urinary incontinence (UI) in older women (≥ 65) living in residential care facilities (RCFs).

DESIGN

Cross-sectional, retrospective survey of a population-based sample, the 2010 National Survey of Residential Care Facilities (NSRCF).

SETTING

United States.

PARTICIPANTS

Participants in the 2010 NSRCF (N = 8,094).

MEASUREMENTS

Sociodemographic and health indicators associated with UI.

RESULTS

Data from 4,930 women were available for analysis, 44.6% of whom had UI. Statistically significant differences were found between the samples of continent women and incontinent women in marital status (P = .001), educational level (P = .04), and length of stay (P = .03). Significant differences were also found between continent and incontinent women in activity of daily living (ADL) scores (P < .001), overall health status (P < .001), and comorbidities (P < .001). The strongest association was severe impairment in ADLs (adjusted odds ratio (OR) = 21.59, 95% confidence interval (CI) = 16.07-29.01), followed by moderate impairment in ADLs (OR = 3.41, 95% CI = 2.61-4.44).

CONCLUSION

UI is highly prevalent in older women residing in RCFs and is associated with severe impairment in ADLs. A comprehensive assessment including physical function status or early detection in physically functional impairment in RCFs is suggested to prevent or delay onset of or improve existing UI.

Urinary incontinence and risk of functional decline in older women: data from the Norwegian HUNT-study

Background

The main objective of the present study was to determine whether UI is an independent predictor of ADL decline and IADL decline in elderly women. We also aimed to find out whether incontinent subjects were at higher risk of needing help from formal home care or home nursing care during 11 year follow-up.

Methods

A prospective cohort study conducted as part of the North-Trøndelag Health Study 2 and 3. Women aged 70–80 years when participating in the HUNT 2 study, who also participated in the HUNT 3 study, were included in this study. Analyses on self-reported urinary incontinence at baseline and functional decline during a11-year period were performed for incontinent and continent subjects.

Results

Baseline prevalence of urinary incontinence was 24%. At on average eleven year follow up, logistic regression analysis showed a significant association between incontinence and decline in activities of daily living (ADL) (OR =2.37, 95% CI =1.01-5.58) (P=0.04). No association between urinary incontinence and instrumental activities of daily living (IADL) in incontinent women compared with continent women was found (OR=1.18, CI=.75-1.86) (P=.46). Data were adjusted for ADL, IADL and co morbid conditions at baseline. No significant differences in need of more help from formal home care and home nursing care between continent and incontinent women were found after 11 years of follow-up.

Conclusions

Urinary incontinence is an important factor associated with functional decline in women aged 70–80 years living in their own homes. At eleven years of follow up, no significant differences in need of more help from formal home care and home nursing care between continent and incontinent women were found.

Does improved functional performance help to reduce urinary incontinence in institutionalized older women? A multicenter randomized clinical trial

Background

Urinary incontinence (UI) is a major problem in older women. Management is usually restricted to dealing with the consequences instead of treating underlying causes such as bladder dysfunction or reduced mobility.

The aim of this multicenter randomized controlled trial was to compare a group-based behavioral exercise program to prevent or reduce UI, with usual care. The exercise program aimed to improve functional performance of pelvic floor muscle (PFM), bladder and physical performance of women living in homes for the elderly.

Methods

Twenty participating Dutch homes were matched and randomized into intervention or control homes using a random number generator. Homes recruited 6–10 older women, with or without UI, with sufficient cognitive and physical function to participate in the program comprising behavioral aspects of continence and physical exercises to improve PFM, bladder and physical performance. The program consisted of a weekly group training session and homework exercises and ran for 6 months during which time the control group participants received care as usual. Primary outcome measures after 6 months were presence or absence of UI, frequency of episodes (measured by participants and caregivers (not blinded) using a 3-day bladder diary) and the Physical Performance Test (blinded). Linear and logistic regression analysis based on the Intention to Treat (ITT) principle using an imputed data set and per protocol analysis including all participants who completed the study and intervention (minimal attendance of 14 sessions).

Results

102 participants were allocated to the program and 90 to care as usual. ITT analysis (n = 85 intervention, n = 70 control) showed improvement of physical performance (intervention +8%; control −7%) and no differences on other primary and secondary outcome measures. Per protocol analysis (n = 51 intervention, n = 60 control) showed a reduction of participants with UI (intervention −40%; control −28%) and in frequency of episodes (intervention −51%; control −42%) in both groups; improvement of physical performance (intervention + 13%; control −4%) was related to participation in the exercise program.

Conclusions

This study shows that improving physical performance is feasible in institutionalized older women by exercise. Observed reductions in UI were not related to the intervention. [Current Controlled Trials ISRCTN63368283]

Prevalência, tipologia e sintomas de gravidade da incontinência urinária em mulheres idosas segundo a prática de atividade física

INTRODUÇÃO: A prática de atividade física (AF) é importante para a população idosa, graças aos beneficios biopsicossociais. A incontinência urinária (IU) também vem sendo analisada, pois o avanço da idade é um fator de risco importante na sua ocorrência. OBJETIVO: Verificar a prevalência, a tipologia e os sintomas de gravidade da IU entre mulheres idosas segundo a prática de AF regular. MATERIAIS E MÉTODOS: Participaram deste estudo 209 idosas, divididas em três grupos, segundo o nível de AF. Foram coletados dados referentes à presença, tipologia, duração e gravidade dos sintomas da IU. Utilizou-se estatística descritiva e inferencial, por meio dos testes Qui-Quadrado, Mann-Whitney e Análise de Variância, conforme os grupos de variáveis. Adotou-se nível de significância de 5%. RESULTADOS: A presença de IU na amostra total foi de 33,3%, sendo a menor prevalência entre as idosas mais ativas (28,9%). Quanto à tipologia, 28,7% apresentaram IU de esforço (IUE), 14,8% IU de urgência (IUU) e 10,5% IU mista (IUM). A presença de IUU (p = 0,05) e IUM (p = 0,04) associou-se com o grupo de mulheres sedentárias. A prática de ginástica associou-se com a ausência de IU (p = 0,003). Em 43,5% da amostra, o início dos sintomas de gravidade deu-se após a menopausa. A retenção de urina sem dificuldade associou-se com a prática de AF (p = 0,029). CONCLUSÃO: A menor incidência de IU entre as idosas muito ativas pode ser atribuída aos benefícios da AF moderada ao mecanismo de continência. Além disso, a prática de exercícios físicos também parece minimizar os sintomas de urgência miccional.

Acidic fruit intake in relation to incidence and progression of urinary incontinence

INTRODUCTION AND HYPOTHESIS

Acidic fruits are commonly cited in the lay press as potential bladder irritants that may promote urinary incontinence (UI), but no epidemiologic studies have examined this issue. We hypothesized that higher intake of acidic fruits might be related to greater risk of UI incidence and progression in women.

METHODS

In one set of analyses, we included women without UI at study baseline in the Nurses' Health Studies (NHS), with 34,144 women aged 54-79 in NHS I and 31,024 women aged 37-54 in NHS II. These cohorts were established among women living in the USA. Incident UI was ascertained over 4 years of follow-up, and acidic fruit consumption was measured by food frequency questionnaire prior to UI onset. In a second set of analyses, we examined UI progression over 2 years of follow-up among 11,764 women in NHS I and 11,299 women in NHS II with existing UI. Multivariable-adjusted relative risks were calculated for the associations of acidic fruit intake and UI incidence and progression.

RESULTS

We found no relation between acidic fruit intake and risk of developing UI, including urgency, mixed, and stress UI. In addition, there was no association between consumption of acidic fruits and UI progression, regardless of UI type.

CONCLUSIONS

No associations were detected between acidic fruit intake and UI in this large, prospective study of women. These data have implications for the development of evidence-based dietary guidelines around acidic fruits and UI, particularly because acidic fruits likely have many health benefits.

Residents' perspectives on urinary incontinence: a review of literature

BACKGROUND

Individuals in residential aged care facilities experience urinary incontinence more than any other single population. Despite these factors, the impact of the condition on their quality of life, their perspectives of living with the condition, and their preferences for care have received little research attention.

AIM

To provide a descriptive overview of research about; the impact of urinary incontinence on residents' quality of life; residents' perspectives of having urinary incontinence; and their preferences for continence care'.

DESIGN

A descriptive review of literature.

METHOD

A broad search was undertaken for qualitative and quantitative research that evaluated residents' quality of life related to urinary incontinence; their perspectives on having urinary incontinence, and their preferences for managing it. Data were displayed in tabular format, summarized, and described.

RESULTS

Ten studies were identified and reviewed (six qualitative and four quantitative). They reveal many residents' value having independent bowel and bladder function, but believe that incontinence in inevitable and intractable. Some adopt self management strategies, however considerable barriers hinder their ability to maintain continence and manage incontinence. Residents often have low expectations, and hence decline further evaluation and treatment. Some express satisfaction with continence care even if this care is not consistent with their preferences. Little is known about how cognitively impaired residents perceive their condition. However some individuals with cognitive impairment respond with acute anxiety when carers' attempt to provide continence care.

CONCLUSION

Residents' perspectives on incontinence and preferences for continence care relate to low expectations for improvement. Such misconceptions should be addressed and residents and their family members should be given a range of options from which to choose. As urinary incontinence impacts on residents' quality of life, it is also important that continence care is delivered in a participative and sensitive way.

A healthy bladder: a consensus statement

A panel of experts in urology, urogynecology, nursing, and behavioral therapy convened in 2010 to discuss the importance of a healthy bladder on overall health. They determined that a consensus statement was necessary to raise awareness among the general public, healthcare providers, payors, and policymakers, with the goals of minimizing the impact of poor bladder health and stimulating primary prevention of bladder conditions. In this statement, 'healthy' bladder function is described, as well as internal and external factors that influence bladder health. It is suggested that primary prevention strategies should be aimed at providing education regarding normal lower urinary tract structures and functioning to the public, including patients and healthcare providers. This education may promote the achievement of optimal bladder health by increasing healthy bladder habits and behaviors, awareness of risk factors, healthcare seeking, and clinician engagement and reducing stigma and other barriers to treatment. Promoting optimal bladder health may reduce the personal, societal and economic impact of bladder conditions, including anxiety and depression and costs associated with conditions or diseases and their treatment. While adopting healthy bladder habits and behaviors and behaviors may improve or maintain bladder health, it is important to recognize that certain symptoms may indicate the presence of conditions that require medical attention; many bladder conditions are treatable with a range of options for most bladder conditions. Lastly, the authors propose clinical directives based on persuasive and convergent research to improve and maintain bladder health. The authors hope that this statement will lead to promotion and achievement of optimal bladder health, which may improve overall health and help minimize the effects of bladder conditions on the public, healthcare professionals, educators, employers, and payors. The advisors are in consensus regarding the recommendations for improving and maintaining bladder health presented herein.

Effect of weight loss on urinary incontinence in women

BACKGROUND

The purpose of this research was review the epidemiology of the association of obesity and urinary incontinence, and to summarize the published data on the effect of weight loss on urinary incontinence.

METHODS

A literature review of the association between urinary incontinence and overweight/obesity in women was performed. Case series and clinical trials reporting the effect of surgical, behavioral, and/or pharmacological weight loss on urinary incontinence are summarized.

RESULTS

Epidemiological studies demonstrate that obesity is a strong and independent risk factor for prevalent and incident urinary incontinence. There is a clear dose-response effect of weight on urinary incontinence, with each 5-unit increase in body mass index associated with a 20%-70% increase in risk of urinary incontinence. The maximum effect of weight on urinary incontinence has an odds ratio of 4-5. The odds of incident urinary incontinence over 5-10 years increase by approximately 30%-60% for each 5-unit increase in body mass index. There appears to be a stronger association between increasing weight and prevalent and incident stress incontinence (including mixed incontinence) than for urge incontinence. Weight loss studies indicate that both surgical and nonsurgical weight loss leads to significant improvements in prevalence, frequency, and/or symptoms of urinary incontinence.

CONCLUSION

Epidemiological studies document overweight and obesity as important risk factors for urinary incontinence. Weight loss by both surgical and more conservative approaches is effective in reducing urinary incontinence symptoms and should be strongly considered as a first line treatment for overweight and obese women with urinary incontinence.
