Effects of urinary incontinence, comorbidity and race on quality of life outcomes in women.

PURPOSE: We investigated the effects of comorbidity and urinary incontinence on both generic and incontinence specific quality of life outcome measures, and investigated whether the association between urinary incontinence and quality of life varies by race. MATERIALS AND METHODS: Study participants were 2,109 women 40 to 69 years old randomly selected from an urban health maintenance organization and interviewed in person for a study of risk factors for urinary incontinence. The sample was racially diverse consisting of 48% white, 18% black, 17% Hispanic and 16% Asian-American women. In addition to incontinence, reproductive and medical history questionnaires, all participants completed the Medical Outcomes Study Short Form 36, a measure of health related quality of life. All participants with daily and weekly incontinence (29%) completed the Incontinence Impact Questionnaire, an incontinence specific quality of life measure. The health maintenance organization's inpatient and outpatient electronic databases were used to calculate a Charlson comorbidity index score for each participant. ANCOVA was used to produce a model adjusting for sociodemographic variables, comorbidity and incontinence frequency. The same model was run for each of 4 racial groupings to examine differences by race/ethnicity. RESULTS: Urinary incontinence is significantly associated with a decreased quality of life and those with more frequent incontinence have significantly lower quality of life scores. In our model the Charlson score, an objective measure of comorbidity based on hospital and physician records, also has a significant negative impact on quality of life. When comorbidity is controlled, incontinence frequency continues to have a significant negative association with quality of life except among the sickest women. For women with the greatest extent of comorbidity, incontinence frequency is not significantly associated with negative quality of life outcomes. We did not find clear patterns of variation by race. CONCLUSIONS: Urinary incontinence and comorbidity each have an independent and significant role in reducing quality of life outcomes for all but the sickest women.

Urinary incontinence and pelvic floor dysfunction in Asian-American women.

OBJECTIVE: The objective of the study was to describe the prevalence, risk factors, and impact of urinary incontinence and other pelvic floor disorders among Asian-American women. STUDY DESIGN: This was a population-based cohort study of older women randomly selected from age and race strata. RESULTS: Weekly urinary incontinence was reported by 65 of 345 Asian women (18%), with stress and urge incontinence being approximately equally common. In multivariate analysis, higher body mass index (greater than 25 kg/m2) was associated with both stress incontinence (odds ratio 4.90, 95% confidence interval 1.76 to 13.68) and urge incontinence (odds ratio 2.49, 95% confidence interval 1.01 to 6.16) in Asians. Hysterectomy was a significant risk factor for stress incontinence (odds ratio 2.79, 95% confidence interval 1.03 to 7.54). Only 34% of Asian women with weekly urinary incontinence reported ever having sought treatment. Pelvic floor exercises were the most common form of treatment, being used by 29% of Asian women with weekly incontinence. Asians were less likely then white women to report anal incontinence (21% versus 29%, P = .007), although this difference became nonsignificant after adjusting for differences in risk factors. CONCLUSION: Asian women share some risk factors for stress and urge urinary incontinence with white women. Urinary incontinence is associated with anal incontinence among Asian women.
