The relationship between BMI and urinary incontinence subgroups: results from EpiLUTS.
To evaluate the relationship between body mass index (BMI) and urinary incontinence (UI) in adults ≥40 from the United States, United Kingdom, and Sweden.
This was a secondary analysis of EpiLUTS-a population-representative, cross-sectional, Internet-based survey conducted to assess the prevalence and HRQL impact of urinary symptoms. UI was evaluated by the LUTS Tool and categorized by subgroups: no UI, urgency urinary incontinence (UUI), stress urinary incontinence (SUI), mixed urinary incontinence (MUI) (UUI + SUI), UUI + other UI (OI), SUI + OI, and OI. Descriptive statistics were used. Logistic regressions examined the relationship of BMI to UI controlling for demographics and comorbid conditions.
Response rate was 59%; 10,070 men and 13,178 women were included. Significant differences in BMI were found across UI subgroups. Obesity rates were highest among those with MUI (men and women), SUI + OI (women), UUI and UUI + OI (men). Logistic regressions of each UI subgroup showed that BMI ≥ 30 (obese) was associated with UI in general and MUI (women) and UUI + OI (men). Among women, being obese increased the odds of having SUI and SUI + OI. Women with BMI 25-29.9 (overweight) were more likely to have UI in general and SUI with and without other incontinence (SUI, MUI, and SUI + OI). Being overweight was unrelated to any form of UI in men.
Results were consistent with prior research showing BMI is associated with higher risk of UI. These findings indicate substantial differences in obesity by gender and UI subtype, suggesting different mechanisms for UI other than purely mechanical stress on the bladder.

Incidence and risk factors of female urinary incontinence: a 4-year longitudinal study among 24 985 adult women in China.
To estimate the incidence of urinary incontinence (UI), including its subtypes stress UI (SUI), urgency UI (UUI) and mixed UI (MUI), and to examine risk factors for de novo SUI and UUI in Chinese women.
Nationwide longitudinal study.
Six geographic regions of China.
Women aged ≥20 years old were included using a multistage, stratified, cluster sampling method.
This study was conducted between May 2014 and March 2016, with follow up in 2018. Data on demographics, medical history, lifestyle and physiological and anthropometric information were collected.
Incidence, rate ratio (RR).
Analyses included 24 985 women (mean age 41.9 years).The follow-up response rate was 55.5%, median follow-up time was 3.7 years. The standardised incidences of UI, SUI, UUI and MUI were 21.2, 13.1, 3.0 and 5.1 per 1000 person-years, respectively. Risk factors for de novo SUI included delivery pattern (vaginal spontaneous delivery RR 2.12, 95% CI 1.62-2.78 and instrumental delivery RR 3.30, 95% CI 1.99-5.45), high body mass index (BMI) (overweight RR 1.52, 95% CI 1.33-1.74 and obesity RR 1.67, 95% CI 1.32-2.11), cigarette smoking (RR 1.54, 95% CI 1.12-2.12), chronic cough (RR 1.44, 95% CI 1.17-1.76), diabetes (RR 1.33, 95% CI 1.10-1.60) and older age (50-59 years RR 1.49, 95% CI 1.16-1.90 and 60-69 years RR 1.61, 95% CI 1.22-2.13).The risk factors significantly associated with de novo UUI were age (RR increased from 1.21, 95% CI 0.74-1.99, at 30-39 years to 6.3, 95% CI 3.85-10.30, at >70 years) and diabetes (RR 1.48, 95% CI 1.05-2.09).
The incidence of female UI is 21.2 per 1000 person-years in China. Delivery (vaginal spontaneous delivery, instrumental delivery), high BMI, cigarette smoking, chronic cough, diabetes and older age were risk factors.
The incidence of female urinary incontinence was 21.2 per 1000 person-years in China. Delivery, BMI, diabetes and old age are risk factors.

Incidence and remission of stress, urge, and mixed urinary incontinence in midlife and older women: A longitudinal cohort study.
To analyze factors related to the incidence and remission of stress urinary incontinence (SUI), urge urinary incontinence (UUI), and mixed urinary incontinence (MUI) among women at midlife.
A total of 2115 women participants in a prospective longitudinal survey (GAZEL cohort) were included. In 2000 and 2008, a specific questionnaire about urinary incontinence (UI) symptoms was sent to all participants. Incidence, remission, and risk factors associated with each type of UI were considered.
Within our population followed up for 8 years, we observed an overall incidence rate of UI of 21.9% (95% CI, 19.6-24.2%) and a remission rate of 33.3% (30.1-36.5%). For the different UI types, the incidence and remission rates were respectively 14.9% (12.9-24.2%) and 37.9% (37.8-42.0%) for SUI, 3.2% (2.2-4.2%) and 25.5% (3.5-37.5%) for UUI, 3.1% (2.1-4.1%) and 24.6% (19.3-29.9%) for MUI. Educational level, increase in body mass index (BMI), BMI and depression at inclusion were associated with SUI incidence. The history of surgery for UI was associated with the incidence of UUI and MUI. Surgery for SUI was significantly associated with remission, while pelvic floor rehabilitation and vaginal delivery were significantly associated with a lower SUI remission. Vaginal delivery was also negatively associated with MUI remission.
The influence of the standard risk factors seems to differ in each type of UI.
