Associations between obesity, physical fitness, and urinary incontinence in non-institutionalized postmenopausal women: The elderly EXERNET multi-center study

Weight-adjusted-waist index is positively associated with urinary incontinence: results from the National Health and Nutrition Examination Survey (NHANES) 2001-2018

BACKGROUND

Urinary incontinence (UI) is closely related to obesity. The aim of this study is to evaluate the association of a novel anthropometric indicator weight-adjusted-waist index (WWI) with UI.

METHODS

This cross-sectional study used the data from National Health and Nutrition Examination Survey (NHANES) 2001-2018. Weighted multivariable logistic regression was used to evaluate the relationship between WWI and three types of UI [stress UI (SUI), urgency UI (UUI), and mixed UI (MUI)]. The receiver operating characteristic (ROC) curve and Delong et al.'s test were utilized for comparison of the predictive capability for UI between WWI and body mass index (BMI), waist circumference (WC).

RESULTS

A total of 41,614 participants were included in this study, of whom 23.57% had SUI, 19.24% had UUI, and 9.43% had MUI. In the fully adjusted model, WWI was positively associated with three types of UI [SUI: odds ratio (OR) = 1.19, 95%Confidence interval (CI) 1.13-1.25; UUI: OR = 1.18, 95%CI 1.13-1.24; MUI: OR = 1.19, 95%CI 1.11-1.27, all p < 0.001]. Compared to the lowest WWI interval, the positive correlation between WWI and UI still existed in the highest WWI group after converting WWI to a categorical variable by quartiles (SUI: OR = 1.52, 95%CI 1.35-1.71, p < 0.001; UUI: OR = 1.50, 95%CI 1.33-1.69, p < 0.001; MUI: OR = 1.55, 95%CI 1.32-1.83, p < 0.001). WWI had a stronger prediction for three types of UI than BMI and WC (all p < 0.001).

CONCLUSION

A higher WWI was linked with an increased likelihood of three types of UI (SUI, UUI, and MUI) in the United State population. Compared to BMI and WC, WWI had a stronger predictive power for UI. WWI may be a better adiposity parameter for evaluating UI.

Patterns of sedentary behavior among older women with urinary incontinence and urinary symptoms: a scoping review

BACKGROUND

Independent of physical activity, sedentary behavior has emerged as a significant risk factor for health. Particularly, older adults spent as high as 13 h daily on sedentary activities, which account for 98% of their awake times. Although there is growing evidence revealing the potential association between sedentary behavior and urinary incontinence (UI) across populations of different ages, the relationship between sedentary behavior and urinary symptoms in older women, who are twice as likely to have UI than older men, has not been reviewed. This scoping review aimed to synthesize available evidence of the relationship between sedentary behavior and urinary symptoms in noninstitutionalized older women.

METHODS

Six electronic databases (PubMed, Web of Science, SPORTDiscus, Ovid Nursing Database, EMBASE, and MEDLINE) were searched from their inception to April 2023. Observational and experimental studies that measured sedentary behavior using objective and/or self-reported methods in older women aged 60 + years having any type of UI, with English full texts available, were included. Relevant data, including sedentary patterns (types, definitions, measurements, and daily patterns) and UI types were tabulated. A narrative synthesis of the findings was also conducted.

RESULTS

A total of seven studies (n = 1,822) were included for review and reporting. Objective measurement showed that older women with UI were engaged in > 8 h sedentary activities daily (493.3-509.4 min/day), which accounted for 73% of their awake times. The duration of self-reported sedentary behavior was lower than the time measured objectively, and the average weekday sitting time was 300-380 min/day. With or without adjustment for confounding factors (e.g., age and number of vaginal deliveries), the daily proportion of sedentary time and average duration of sedentary bouts were positively associated with the prevalence of urgency UI. Notably, sedentary patients with UI were more likely to have lower urinary tract symptoms, including bothersome incontinence, to use incontinence products, and to have nocturia episodes, than their age-matched counterparts who were less sedentary.

CONCLUSION

Our findings suggest a potential relationship between sedentary behavior and UI in older women, but the causality of the relationship remains unclear. To further inform the clinical role of sedentary behavior in the context of UI, a greater number of rigorous studies with a prospective study design is urgently needed.

Association between Sitting Time and Urinary Incontinence in the US population: Data from the National Health and Nutrition Examination Survey (NHANES) 2007 to 2018

Background

Urinary incontinence (UI) is a common health problem that affects the quality of life and health of millions of people in the United States (US). We aimed to investigate the association between sitting time and UI symptoms in the US population.

Methods

A cross-sectional survey of participants aged 20 and above from the National Health and Nutrition Examination Survey 2007-2018 was performed. A self-report questionnaire that reported complete data on UI, sitting time and covariates was included. Weighted multivariable logistic and regression models were used to assess the association between sitting time and UI symptoms.

Results

A total of 22,916 participants were enrolled. Prolonged sitting time was associated with urgency UI (UUI, odds ratio [OR] = 1.2, 95% confidence interval [CI] = 1.1 to 1.3, p = 0.001). Compared with patients with sitting a time shorter than 7 hours (h), moderate recreational activity modified the association between sitting time and mixed UI in males in the fully adjusted model (OR = 2.5, 95% CI = 1.4 to 4.5, p = 0.002). A sitting time over 7 h was related to mixed UI (MUI, OR = 1.6, 95% CI = 1.1 to 2.2, p = 0.01) in males, and stress UI (SUI, OR = 0.9, 95% CI = 0.8 to 0.98, p = 0.03) in females. However, no significant difference was found among the UI, SUI, and MUI groups in fully adjusted model.

Conclusions

A prolonged sitting time (≥7 h) was associated with UUI symptoms in all populations, SUI symptoms in females and MUI symptoms in males compared with sitting time lower than 7 h. Compared with those sit shorter than 7 h, moderate recreational activity may be a modifier between prolonged sitting and MUI symptoms in male participants, which warrants further studies for confirmation.

Pelvic floor dysfunction and electrophysiology in postpartum women at 6-8 weeks

Objective: To investigate the incidence of pelvic floor dysfunction (PFD) and electrophysiological indicators in postpartum women at 6-8 weeks and explore the influence of demographic characteristics and obstetric factors. Methods: A survey questionnaire collected information about the conditions of women during their pregnancy and puerperal period and their demographic characteristics; pelvic organ prolapse quantitation (POP-Q) and pelvic floor muscle electrophysiology (EP) examination were conducted in postpartum women at 6-8 weeks. Results: Vaginal delivery was a risk factor for anterior pelvic organ prolapse (POP) (OR 7.850, 95% confidence interval (CI) 5.804-10.617), posterior POP (OR 5.990, 95% CI 3.953-9.077), anterior and posterior stage II POP (OR 6.636, 95% CI 3.662-15.919), and postpartum urinary incontinence (UI) (OR 6.046, 95% CI 3.894-9.387); parity was a risk factor for anterior POP (OR 1.397,95% CI 0.889-2.198) and anterior and posterior stage II POP (OR 4.162, 95% CI 2.125-8.152); age was a risk factor for anterior POP (OR 1.056, 95% CI 1.007-1.108) and postpartum UI (OR 1.066, 95% CI 1.014-1.120); body mass index (BMI) was a risk factor for postpartum UI (OR 1.117, 95% CI 1.060-1.177); fetal birth weight was a risk factor for posterior POP (OR 1.465, 95% CI 1.041-2.062); and the frequency of pregnancy loss was a risk factor for apical POP (OR 1.853, 95% CI 1.060-3.237). Conclusion: Pelvic floor muscle EP is a sensitive index of early pelvic floor injury. The changes in muscle strength and fatigue degree coexist in different types of postpartum PFD, and each has its own characteristics.

Do levels of self-efficacy affect urinary incontinence, falls, quality of life, sleep, and physical activity in elderly people with urinary incontinence?

BACKGROUND

Our study aims to determine whether different self-efficacy (SE) levels affect urinary incontinence symptoms, falls, quality of life, sleep, and physical activity in elderly individuals with incontinence. Our secondary aim is to examine the relationship between SE levels and urinary incontinence severity, quality of life, sleep status, fear of falling, and physical activity level.

METHODS

One hundred twenty elderly individuals (median age: 71 years) with urinary incontinence participated in the cross-sectional study. Participants were divided into 3 groups as levels of low, moderate, and high according to their Geriatric SE Index for Urinary Incontinence (GSE-UI). Urogenital Distress Inventory (UDI-6), Incontinence Impact Questionnaire (IIQ-7), Incontinence Quality of Life Scale (I-QOL), Pittsburgh Sleep Quality Index (PSQI), Fall Efficacy Scale (FES), Rapid Assessment Physical Activity (RAPA), and International Physical Activity Questionnaire Short Form (IPAQ-SF) assessments associated with incontinence were performed. Data were analyzed using Mann-Whitney U, Kruskal-Wallis tests, and Spearman's correlation.

RESULTS

A significant difference was found in UDI-6, IIQ-7, I-QOL, and FES belonging to three groups according to GSE-UI levels (p ˂0.01, p ˂0.01, p ˂0.01). It was determined that the group with low GSE-UI level had the highest incontinence symptoms, fear of falling, and the lowest quality of life statistically significant. A negative moderate significant correlation was found between GSE-UI scores and UDI-6 (r: - .67, p ˂0.01), IIQ-7 (r: - .67, p ˂0.01), and FES (r: - .46, p ˂0.01).

CONCLUSION

In elderly individuals with urinary incontinence, the level of SE may affect incontinence symptoms, severity, fear of falling, and quality of life and may be an important factor for incontinence. An increased level of SE may lead to positive effects on the user interface. Further studies in this field are needed.

Urinary Incontinence in Physically Active Older Women of Northeast Brazil

Low- and moderate-impact physical activity (PA) is associated with the prevention of urinary incontinence (UI). The objective of the cross-sectional study presented herein is to analyze the factors associated with UI in physically older active women who participate in senior community groups. The variable UI was measured by the International Consultation Incontinence Questionnaire Short Form (ICIQ-SF). Socioeconomic variables were also collected, along with data on life habits and clinical history. The multivariate analysis employed Poisson's Regression with robust variance for factors associated with UI. Of the 106 participants evaluated, 54.7% presented UI, of which stress incontinence was more frequent, with 40.6%. UI presented a statistically significant association with dizziness/loss of balance during Activities of Daily Living (ADL) (prevalence ratio-PR 1.48; 95% CI 1.06-2.07) and nocturia (PR 1.63; 95% CI 1.05-2.55). Despite PA being a protection factor, UI presented an elevated prevalence in the older population, and therefore, other biological, social, and cultural aspects could also contribute to the occurrence of UI in this age group. Moreover, physically active older women with UI presented nocturia and dizziness/loss of balance during ADL, regardless of education levels and the number of births. These findings can help improve multi-professional programs aimed at promoting, preventing, and managing UI in the public.

Anthropometric indicators as predictors of pelvic floor muscle distress in young women

AIM

To identify anthropometric indicators that could predict pelvic floor muscle distress (PFMD) in young women.

METHOD

A cross-sectional study was conducted, whose sample consisted of 54 women aged between 18 and 35 years. The Pelvic Floor Distress Inventory was used to assess the PFMD. The anthropometric indicators evaluated were body mass index (BMI) being measured the weight and height, body fat percentage (skinfolds), waist circumference (WC), waist-to-hip ratio (WHR), and relative fat mass (RFM), which is calculated from height and WC. Descriptive and inferential statistics (Spearman correlation, simple linear regression, and receiver operating characteristic curve) were used, with a significance level of 5%.

RESULTS

The PFMD and the anthropometric indicators BMI (r = .43), body fat percentage (r = .42), WC (r = .46), WHR (r = .49), and RFM (r = .48) showed a positive and moderate correlation (P < .01). In all, 24%, 23%, 20%, and 18% of the PFMD can be credited to RFM, WC, WHR, and body fat percentage, respectively. The cut-off point for RFM was 38.44 for the symptom of pressure in the lower abdomen and 36.24 for symptom of stress urinary incontinence and incomplete emptying of the bladder.

CONCLUSION

Anthropometric indicators of body fat percentage, WC, WHR, and RFM can be predictors of PFMD in young women minimally symptomatic.

Relationship of Body Composition and Urinary Incontinence in Women: A Cross-Sectional Case-Control Study

OBJECTIVE

To describe the profile of segmental body composition through the bioelectrical impedance analysis (BIA) method in continent and incontinent women and analyze the association between overweight/obesity and urinary incontinence (UI).

METHODS

This was a cross-sectional case-control study that included women aged between 20 and 65 years, who were not pregnant, were outside of their menstrual period, without neurological, psychiatric, orthopedic, or cardiac comorbidities. The presence of UI was verified using the International Consultation on Incontinence Questionnaire-Short Form. Segmental body composition was assessed with BIA. The independent Student t test was used to compare body composition means between groups, and multivariate logistic regression was used to test the association between body composition and UI.

RESULTS

The study included 62 women with a mean age of 34.4 ± 11.6 years, of whom 27 (43.5%) had UI. Of these, 15 (55.6%) were nulliparous and had a body mass index of 25.1 ± 4.2 kg/m, similar to that of continent women, who had a body mass index of 23.6 ± 3.9 kg/m (P=0.16). The sociodemographic and obstetric data were similar among continent and incontinent women. With respect to the parameters of segmental body fat, visceral fat, and waist circumference, incontinent women presented higher values than the continent group. In the final multivariate analysis model, women with high levels of visceral fat had a 1.13-times higher likelihood of presenting UI.

CONCLUSIONS

In adult women, there is an association between the level of visceral fat assessed by BIA and complaints of urinary loss, being more evident in overweight and obese women.

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.

Association of Physical Activity With Urinary Incontinence in Older Women: A Systematic Review

OBJECTIVE

To analyze the scientific evidence on the association of physical activity with urinary incontinence in older women.

DESIGN

Searches were performed in MEDLINE, PubMed, CINAHL, Web of Science, SCOPUS, and ScienceDirect. Observational studies were included. The following search terms were used: urinary incontinence, older adult, and physical activity. Methodological quality was assessed using the checklist proposed by Downs and Black.

RESULTS

Ten articles were included. Sedentary lifestyle and <150 min/week of physical activity are at risk of developing urinary incontinence. Walking (at least 30 min) and physical activities (600-1,500 and 600 METs/min per week) prevent urinary incontinence. Seven of the 10 studies indicated a good level of methodological quality.

CONCLUSIONS

Sedentary lifestyle is at risk of urinary incontinence, and walking, moderate and vigorous physical activities are associated with prevention of urinary incontinence.

Further understanding of the Senior Fitness Test: Evidence from community-dwelling high function older adults in Hong Kong

OBJECTIVES

This study examined the factor structure of the Senior Fitness Test and examined its measurement and structural invariance across participants with normal body weight and participants who were overweight.

METHODS

Eight hundred and forty-five community-dwelling older adults in Hong Kong participated in this study. Their functional fitness was assessed using the Senior Fitness Test. Confirmatory factor analysis was conducted to examine and compare two competing models: a one-factor model and a second-order model. Multiple-group confirmatory factor analysis was conducted to evaluate the measurement and structural invariance of the SFT measurement model. Multiple fit indices were used to evaluate the adequacy of the model fit to the data.

RESULTS

The second-order model outperformed the one-factor model. For men participants, the second-order 4-factor model was indicated, while for women participants, the second-order 5-factor model was evidenced. The measurement and structural invariance of the SFT measurement model across normal weight and overweight participants were also supported.

CONCLUSION

This study provided initial evidence for the construct validity of the SFT. However, there were some differences in the factor structure of the SFT for men and women participants. Body composition did not necessarily reflect the functional fitness of men participants. All of the older adults responded to the testing items in a similar way regardless of body weight status in both men and women samples. The significance of each component for functional fitness was also similar for participants with different body weight statuses.

Pelvic, anorectal and urinary symptoms according to the nutritional status of adult women: A cross-sectional study

ABSTRACT To review the occurrence of pelvic, anorectal and urinary symptoms according to the nutritional status of adultwomen. Methods This is a cross-sectional study with 54 women, aged 18 to 35 years, divided into normal weight (<25kg/m2), overweight (25kg/m2 to 29.99kg/m2) and obesity (≥30kg/m2) according to the body mass index. The presence of pelvic floor muscle dysfunction symptoms was assessed by the Pelvic Floor Distress Inventory and the impact of these symptoms by the Pelvic Floor Impact Questionnaire. Descriptive and inferential statistics were used, with a significance level of 5%. Results Pelvic Floor Distress Inventory total score was 22.95 (SD=26.11) in the eutrophic group and 59.67 (SD=47.80) in the obesity group (p=0.01). Considering the scales, urinary symptoms were higher in obese women than in the eutrophic group (p=0.01). In the assessment of patients with each symptom, a difference (p<0.01) was observed in incomplete bowel emptying, in which the highest frequency occurred in overweight women (47.4%) compared to eutrophic and obese women (both 26.3%). Urinary incontinence symptoms (18.2% in eutrophic women, 27.3% overweight and 54.5% obese), stress urinary incontinence (8.3% eutrophic, 41.7% overweight and 50.0%, obese) and difficulty in emptying the bladder (0.0% eutrophic, 33.3% overweight and 66.7% obese) exhibited higher frequencies (p=0.03; p<0,01 and p=0.02, respectively) in obese women. Conclusion Symptoms of pelvic floor muscles dysfunction, especially urinary tract muscles, occur more frequently in obese adult women when compared to eutrophic women.

Sedentary time in older adults: a critical review of measurement, associations with health, and interventions

Sedentary time (ST) is an important risk factor for a variety of health outcomes in older adults. Consensus is needed on future research directions so that collaborative and timely efforts can be made globally to address this modifiable risk factor. In this review, we examined current literature to identify gaps and inform future research priorities on ST and healthy ageing. We reviewed three primary topics:(1) the validity/reliability of self-report measurement tools, (2) the consequences of prolonged ST on geriatric-relevant health outcomes (physical function, cognitive function, mental health, incontinence and quality of life) and(3) the effectiveness of interventions to reduce ST in older adults.

METHODS

A trained librarian created a search strategy that was peer reviewed for completeness.

RESULTS

Self-report assessment of the context and type of ST is important but the tools tend to underestimate total ST. There appears to be an association between ST and geriatric-relevant health outcomes, although there is insufficient longitudinal evidence to determine a dose-response relationship or a threshold for clinically relevant risk. The type of ST may also affect health; some cognitively engaging sedentary behaviours appear to benefit health, while time spent in more passive activities may be detrimental. Short-term feasibility studies of individual-level ST interventions have been conducted; however, few studies have appropriately assessed the impact of these interventions on geriatric-relevant health outcomes, nor have they addressed organisation or environment level changes. Research is specifically needed to inform evidence-based interventions that help maintain functional autonomy among older adults.This consensus statement has been endorsed by the following societies: Academy of Geriatric Physical Therapy, Exercise & Sports Science Australia, Canadian Centre for Activity and Aging, Society of Behavioral Medicine, and the National Centre for Sport and Exercise Medicine.
