Remission and Transition of Female Urinary Incontinence and Its Subtypes and the Impact of Body Mass Index on This Progression: A Nationwide Population-Based 4-Year Longitudinal Study in China

Abstract

Purpose: We estimated the remission and transition rate between urinary incontinence (UI) subtypes in women with UI and evaluated the impact of body mass index (BMI) on this process. Materials and Methods: A Chinese population-based longitudinal study was conducted. Women aged !20 years were included using a multistage, stratified, cluster sampling method. Self-reported data on demographics, medical history, and physiological and anthropometric information were collected. UI was identified using 2 questions about any leaking symptom of stress UI (SUI) and urgency UI (UUI) in the past 6 months. Predicted probabilities of UI subtypes were calculated using multinomial logistic regression. Results: Analyses included 5,189 women (mean age 52.6 years, mean BMI 23.8 kg/m 2 ), of whom 98.5% were parous. The median followup time was 4.0 years. Overall, the annual remission rate of UI was 12.7% among adult women. Regarding UI subtypes, the remission rates for UUI and SUI were similar, but higher than that for mixed urinary incontinence (MUI; p <0.05). In total, 7.6% of SUI patients and 16.4% of UUI patients developed MUI, and 35.3% of MUI patients continued to report MUI after 4 years. For women aged !60 years with a BMI !24 kg/m 2 and

Associated factors of stress, urgency, and mixed urinary incontinence in a geriatric outpatient assessment of older women with hip fracture

“…Komesu et al found age between 80 and 90 and BMI over 35 to be a predictors of incident MUI, as well as lower remission rates during a 2 year follow-up [18]. In another study by Pang et al, women aged 60 or over and with BMI over 24 had a higher predicted probability of remaining with or progressing to MUI from either SUI or UUI during a 4 year follow-up [45]. Since obesity also exerts challenges to mobilizing and rehabilitating the patient after a hip fracture, and on the other hand these patients frequently suffer from malnutrition [46] and thereby might carry the risk of sarcopenic obesity [47], preventing or managing UI by weight loss presents a clinical challenge in these patients.…”

Analysis of Subtypes of Urinary Incontinence in a Geriatric Outpatient Assessment of Older Women With Hip Fracture

“…[41] Komesu et al found age between 80-90 and BMI over 35 to be a predictors of incident MUI, as well as lower remission rates during a 2-year follow-up [16]. In another study by Pang et al, women aged 60 or over and with BMI over 24 had a higher predicted probability of remaining with or progressing to MUI from either SUI or UUI during a 4-year follow-up [42]. The association between higher BMI and SUI did not reach statistical signi cance in our study, which might be partly explained by the sample size as well as the older age distribution of the study population compared to previous studies.…”

Joint Effect of Physical Activity and Sedentary Behavior with the Female Urinary Incontinence: An Analysis of NHANES 2011–2016

“…However, to the best of our knowledge, this study is the first to investigate the independent and combined effects of leisure-time physical activity and sedentary behavior on different subtypes of UI risk among females. UI can result in enduring physical and psychological distress for patients, with varying degrees of impact observed across different subtypes of UI [20]. In a study from China, women pointed out that the severity of mixed UI surpasses that of stress UI and urgency UI, and the overall health burden (including mental health) experienced by patients with mixed UI exceeds that of those with stress UI and urgency UI [21].…”
