Urinary Incontinence and Depressive Symptoms: The Mediating Role of Physical Activity and Social Engagement

The link between disability and social participation revisited: Heterogeneity by type of social participation and by socioeconomic status

BACKGROUND

While prior literature explores the impact of disability on social participation, the distinct characteristics of diverse social activities could further complicate this relationship. Furthermore, this relationship may exhibit heterogeneity when considering socioeconomic status (SES).

OBJECTIVE

This study aims to investigate whether the relationship between disability and social participation differs depending on the type of social participation, and to what extent this relationship is moderated by SES.

METHODS

Data from seven waves of the Korean Longitudinal Study of Ageing were analyzed. Various types of social participation, including socializing, leisure, volunteer, political, and religious activities, were considered. Individual fixed effects models were employed to account for unobserved individual-level heterogeneity. To investigate the potential moderating role of SES, an interaction term between disability and SES was included.

RESULTS

Disability was associated with a decrease in social participation (b = -0.088). When differentiating types of social participation, the associations were negative for socializing and leisure activities (b = -0.092 and b = -0.012, respectively) and positive for volunteer activities (b = 0.012). The negative association between disability and social participation was generally stronger among higher-SES groups than lower-SES groups. Specifically, the negative association with leisure activities was more pronounced among the high-education groups. In contrast, the positive association with volunteer activities was more evident among the low-education group.

CONCLUSIONS

Disability has a negative association with engagement in socializing and leisure activities and a positive association with engagement in volunteer activities. Policymakers should consider the role of SES in complicating the relationship between disability and social participation.

The use of assistive devices and social engagement among older adults: heterogeneity by type of social engagement and gender

Little is known about the relationship between the use of assistive devices for functional loss and social engagement. This study investigated whether wearing assistive devices (dentures and hearing aids) is associated with social engagement among older adults in South Korea. Potential heterogeneity by type of social engagement (informal social contact versus formal social activity) and gender was also examined. This study analyzed data from 3725 individuals aged 65 or older collected over the course of 6 waves of the Korean Longitudinal Study of Ageing (KLoSA) from 2008 to 2018 (2150 women and 1575 men). Individual fixed effects models were used to account for unobserved individual-level heterogeneity that could confound the relationship between wearing assistive devices and social engagement. The fixed effects estimates showed that wearing assistive devices is associated with a decrease in formal social activity (b =  - 0.034 for dentures and b =  - 0.077 for hearing aids), but not informal social contact. Gender-stratified fixed effects revealed that the association between wearing assistive devices and social engagement is statistically significant only for men. In men, wearing assistive devices is associated with a decrease in formal social activity (b =  - 0.049 for denture and b =  - 0.095 hearing aids). The findings of this study suggest that wearing assistive devices may reduce the formal social activity of older adults, particularly men. Policymakers should consider developing interventions to help older adults overcome the stigma associated with assistive devices, which can hinder their social integration.

Urinary incontinence and life-space activity/mobility additively increase the risk of incident disability among older adults

OBJECTIVES

To examine the associations of a combination of urinary incontinence (UI) and life-space activity/mobility with the risk of incident disability among community-dwelling older adults.

STUDY DESIGN

The participants were 12,808 older adults for the cross-sectional study and 12,516 older adults who completed the follow-up assessment.

MAIN OUTCOME MEASURES

UI was assessed using a questionnaire. Life-space activity/mobility was evaluated using total, physical, and social scores on the Active Mobility Index (AMI). Participants were classified into four groups (high AMI total score + no UI; high AMI total score + UI; low AMI total score + no UI; low AMI total score + UI). Incident disability was extracted from the Japanese Long-Term Care System.

RESULTS

During the 24-month follow-up, 562 participants (4.5 %) developed disability. Those with a low AMI score + no UI (hazard ratio, 1.35; 95 % confidence interval, 1.07-1.71) and those with a low AMI score + UI (hazard ratio, 2.00; 95 % confidence interval, 1.56-2.56) had a higher risk of incident disability than those with a high AMI score + no UI in the follow-up analysis.

CONCLUSIONS

A combination of UI and low AMI score was associated with an increased risk of incident disability, whereas having UI but a high AMI score was not associated with an increased risk of incident disability. Our findings may help identify older adults at high risk of developing disabilities.

U-shaped association between sleep duration and urgency urinary incontinence in women: a cross-sectional study

BACKGROUND

To investigate the association between sleep duration and urgency urinary incontinence (UUI) among adult women.

METHODS

Cross-sectional data were retrieved from the 2005-2014 National Health and Nutrition Examination Survey. To explore the association between sleep duration and urgency urinary incontinence, multivariable logistic regression and restricted cubic spline (RCS) regression analysis was carried out.

RESULTS

Among 9204 adult women, the weighted urinary incontinence prevalence was  31% for urgency urinary incontinence (UUI). The fully adjusted multivariable model revealed that participants with short (< 7 h) or long (> 9 h) sleep duration were more likely to report UUI compared to participants with normal (7-9 h) sleep duration (OR 1.20, 95% CI 1.03-1.40, p = 0.02, OR 1.40, 95% CI 1.11-1.76, p = 0.005, respectively). Subgroup analysis showed no significant interaction. Furthermore, additional analysis demonstrated a U-shaped correlation between sleep duration and incident UUI.

CONCLUSION

The non-linear association exists between sleep duration and urgency urinary incontinence. Compared with insufficient or excessive sleep, normal sleep duration is related to lower prevalence of urgency urinary incontinence. Future prospective longitudinal studies should be conducted to further investigate and determine the degree of the association between sleep time and urgent urinary incontinence.

Interpersonal Stressors and Resources for Support: Associations with Lower Urinary Tract Symptoms and Impact Among Women

Background: This study utilizes Coronary Artery Risk Development in Young Adults (CARDIA) data to examine whether women's perceived emotional support and interpersonal stressors are associated with lower urinary tract symptoms (LUTS) and their impact on quality of life. Materials and Methods: Emotional support was assessed at baseline/year 0 (1985-86), year 2 (1987-88), year 15 (2000-01), and year 20 (2005-06); interpersonal stressors were assessed at years 15 and 20. In 2012-13, LUTS and impact were assessed. LUTS/impact category (a composite variable ranging from bladder health to mild, moderate, and severe LUTS/impact) was regressed on trajectory groups of emotional support from years 0 to 20. Separately, LUTS/impact was regressed on mean emotional support and interpersonal stressors across years 15-20. Analyses were adjusted for age, race, education, and parity (n = 1104). Results: In comparison to women whose support trajectory from years 0 to 20 was consistently high, women whose support decreased from high to low had over twice the odds (odds ratio [OR] = 2.72; 95% confidence interval [CI] = 1.76-4.20) of being classified into a more burdensome LUTS/impact category. Mean support and interpersonal stressors across years 15-20 were independently associated with lower odds (OR = 0.59; 95% CI = 0.44-0.77) and greater odds (OR = 1.52; 95% CI = 1.19-1.94), respectively, of being classified into a more burdensome LUTS/impact category. Conclusions: In the CARDIA cohort, quality of women's interpersonal relationships, assessed between 1985-86 and 2005-06, was associated with LUTS/impact assessed in 2012-13. Additional research collecting LUTS/impact data at multiple time points is needed to test potential bidirectional associations of emotional support and interpersonal stressors with LUTS/impact, as well as potential mechanisms of association.

Characteristics, scope of activity, and negative emotions in elderly women with urinary incontinence: Based on a longitudinal follow-up in Shanghai, China

We conducted a study to assess the characteristics, scope of activity, and negative emotions in elderly women with urinary incontinence (UI) based on a longitudinal follow-up conducted in Shanghai, China from 2013 to 2019. A total of 3,531 elderly women were included in the final analysis, and 697 women who experienced UI during follow-up were included in the UI group. Subjects with UI were subdivided into those with partial UI (UI once a day or less) and UI (frequent UI). Two thousand eight hundred and thirty-four women who did not have UI during the same period served as the control group. The prevalence of UI was 19.74% in this study. Logistic regression analysis revealed that being older (> 80 years of age), having a high level of education (> 12 years; elderly people with a high level of education may pay more attention to their health and notice UI more readily), a low personal monthly income (≤ 3,000 RMB), more gravidity/parity, and having a chronic disease (chronic obstructive pulmonary disease (COPD), dementia, or Parkinson's disease) were risk factors for UI (p < 0.05). About 60% of women in the partial UI group engaged in daily activities outdoors, while this number decreased sharply to 3.6% in the UI group. Women in the UI group were more likely to have negative emotions, such as depression, anxiety, irritability, or feeling worthless (p < 0.001). Among elderly women with dementia, those with UI had defects in terms of judgment in everyday life, the ability of convey information, and the ability to understand information (p < 0.05). More attention needs to be paid to the adverse effects of UI on activities of daily living (ADL) and mental health in the future.
