AI Article Synopsis

  • The study investigates the prevalence of stress urinary incontinence (SUI) among middle-aged and elderly women in mainland China, aiming to fill gaps in existing research.
  • After screening 688 articles, 85 studies were included, revealing an overall SUI prevalence of 24.5%, which exhibits significant statistical heterogeneity.
  • The research identified variations in SUI prevalence based on factors like publication year, study quality, geographical location, and rural versus urban settings, indicating regional differences in the condition's incidence.

Article Abstract

Background And Objective: Stress urinary incontinence (SUI) in women is a common condition that affects middle-aged and elderly women. Currently, there are still many limitations in the epidemiological research on SUI. This study aims to address the gap in the prevalence of female SUI in mainland China and provide theoretical support for the prevention and treatment of SUI.

Methods: A comprehensive literature search was conducted on the prevalence of female SUI in mainland China, systematically searching Chinese and English databases including PubMed, Web of Science, Embase, Cochrane Library, China National Knowledge Infrastructure (CNKI), Wanfang Database, and Weipu Database as of April 1, 2024. Detailed criteria for screening and exclusion were established. The prevalence of SUI in the selected studies was synthesized using Stata MP (version 15) software, and a multisubgroup analysis, a sensitivity analysis, and publication bias detection of the prevalence of SUI were also performed using the software. Additionally, ArcGIS software (version 10.8) and Geoda software (version 1.2) were utilized to explore the geographical distribution characteristics of the prevalence of female SUI in mainland China.

Key Findings And Limitations: A total of 688 articles were screened, and finally 85 articles were included. The overall rate of female SUI in mainland China was 24.5% (95% confidence interval: 22.5-26.5%). The heterogeneity of the study is statistically significant (I = 99.0%,  < 0.001). Based on significant heterogeneity, a multisubgroup analysis was conducted. The results showed that the prevalence of SUI varies among different publication years, literature quality scores, investigators, study settings, sampling methods, provinces, regions, coastal or inland areas, and rural or urban areas. A spatial econometric analysis indicated that the incidence of SUI in the east-west distribution showed a downward trend, while in the north-south distribution, the incidence rate of SUI showed a trend of first increasing and then decreasing. Additionally, a spatial metrology analysis showed similar trends in the distribution of SUI incidence.

Conclusions And Clinical Implications: The high incidence rate of female SUI in mainland China and the regional differences observed indicate the need for further rigorous epidemiological investigation in the future.

Patient Summary: Stress urinary incontinence (SUI) is common among middle-aged and elderly women. The high prevalence of SUI in mainland China and the differences across regions emphasize the need for conducting more robust epidemiological studies in the future.
