Gender-based Variations in Urinary Incontinence Factors Among Older Adults

Overview

This study analyzed sex-specific differences in factors associated with urinary incontinence (UI) among older adults in Germany using data from the GEDA 2019/2020-EHIS survey. It found that UI prevalence is higher in females and is influenced by multiple biopsychosocial factors including age, chronic diseases, physical limitations, and depressive symptoms, with distinct patterns observed between males and females.

Background

Urinary incontinence is a prevalent condition in older adults that significantly impacts quality of life and healthcare resources. Its prevalence is influenced by demographic, lifestyle, mental health, and somatic factors, with females generally showing higher rates due to biological differences, while males often experience UI related to prostate issues. Despite this, few studies have comprehensively compared sex-specific determinants of UI in the general population. The GEDA 2019/2020-EHIS study provides updated, population-based data to address this gap.

Data Highlights

Key Findings

• UI prevalence increases with age and is significantly higher in females compared to males.
• Chronic diseases and physical limitations (ADL impairments) are strongly associated with UI in both sexes.
• Depressive symptoms (PHQ-8 ≥10) are independently linked to higher UI prevalence, highlighting the biopsychosocial impact.
• Higher BMI categories correlate with increased UI risk, with obesity showing a stronger association in females.
• Lower education levels are associated with increased UI prevalence, suggesting socioeconomic influences.
• Sex-specific differences exist in the relative influence of these factors, underscoring the need for tailored clinical approaches.

Clinical Implications

Clinicians should consider the multifactorial nature of urinary incontinence in older adults, including physical, psychological, and socioeconomic factors, with attention to sex-specific differences. Screening for depressive symptoms and functional limitations alongside traditional risk factors like BMI and chronic disease may improve identification and management of UI. Tailored interventions addressing these diverse determinants can enhance patient outcomes and quality of life.

Conclusion

This study highlights distinct gender-based variations in factors contributing to urinary incontinence among older adults, emphasizing the importance of a comprehensive, sex-specific approach to assessment and management in clinical practice.
