Prevalence of Symptomatic Pelvic Floor Disorders in US Women

CONTEXT Pelvic floor disorders (urinary incontinence, fecal incontinence, and pelvic organ prolapse) affect many women. No national prevalence estimates derived from the same population-based sample exists for multiple pelvic floor disorders in women in the United States. OBJECTIVE To provide national prevalence estimates of symptomatic pelvic floor disorders in US women. DESIGN, SETTING, AND PARTICIPANTS A cross-sectional analysis of 1961 nonpregnant women (>or=20 years) who participated in the 2005-2006 National Health and Nutrition Examination Survey, a nationally representative survey of the US noninstitutionalized population. Women were interviewed in their homes and then underwent standardized physical examinations in a mobile examination center. Urinary incontinence (score of >or=3 on a validated incontinence severity index, constituting moderate to severe leakage), fecal incontinence (at least monthly leakage of solid, liquid, or mucous stool), and pelvic organ prolapse (seeing/feeling a bulge in or outside the vagina) symptoms were assessed. MAIN OUTCOME MEASURES Weighted prevalence estimates of urinary incontinence, fecal incontinence, and pelvic organ prolapse symptoms. RESULTS The weighted prevalence of at least 1 pelvic floor disorder was 23.7% (95% confidence interval [CI], 21.2%-26.2%), with 15.7% of women (95% CI, 13.2%-18.2%) experiencing urinary incontinence, 9.0% of women (95% CI, 7.3%-10.7%) experiencing fecal incontinence, and 2.9% of women (95% CI, 2.1%-3.7%) experiencing pelvic organ prolapse. The proportion of women reporting at least 1 disorder increased incrementally with age, ranging from 9.7% (95% CI, 7.8%-11.7%) in women between ages 20 and 39 years to 49.7% (95% CI, 40.3%-59.1%) in those aged 80 years or older (P < .001), and parity (12.8% [95% CI, 9.0%-16.6%], 18.4% [95% CI, 12.9%-23.9%], 24.6% [95% CI, 19.5%-29.8%], and 32.4% [95% CI, 27.8%-37.1%] for 0, 1, 2, and 3 or more deliveries, respectively; P < .001). Overweight and obese women were more likely to report at least 1 pelvic floor disorder than normal weight women (26.3% [95% CI, 21.7%-30.9%], 30.4% [95% CI, 25.8%-35.0%], and 15.1% [95% CI, 11.6%-18.7%], respectively; P < .001). We detected no differences in prevalence by racial/ethnic group. CONCLUSION Pelvic floor disorders affect a substantial proportion of women and increase with age.

Epidemiology and Natural History of Urinary Incontinence

Abstract: This paper examines or current state of knowledge of the epidemiology of urinary incontinence. The population studied was community-dwelling non-institutionalized persons. The review includes discussion of the prevalence, incidence, natural history and presence of racial and ethnic differences in the epidemiology of urinary incontinence. We also review correlates and potential risk factors that have been revealed in epidemiological studies. Differences between epidemiological and clinical approaches to a health problem, help-seeking behavior and methodological issues for research are also discussed. We have reviewed a large number of completed studies in the field of urinary incontinence, and have emphasized high-quality and population-based studies. We also wished to present studies from a variety of countries. Because of the abundance of studies, only a small fraction can be presented here. Other studies may have equal standards and useful information, but lack of space precludes their inclusion.

Epidemiology and natural history of urinary incontinence in women

Understanding the epidemiology (distribution and determinants) of urinary incontinence (UI), as well as its natural history is a very important issue. In this article, we discuss prevalence, incidence, natural history, and the variations that may be related to race and ethnicity. We focus on epidemiologic population comprising community-dwelling women who are not institutionalized. Our review clearly shows that there is a lack of advanced epidemiologic analyses. Variables that better characterize UI include frequency measure, quantity of urine loss, duration, type, and severity. These factors should be incorporated into basic study design so that more advanced and informative analyses may be conducted.

Factors associated with women's decisions to seek treatment for urinary incontinence

BACKGROUND Urinary incontinence is a highly prevalent and burdensome condition among women. However, fewer than half of women with symptoms talk to a physician about incontinence, and the determinants of treatment seeking are not well understood. DESIGN A two-stage cross-sectional survey of adult U.S. women; 45,000 households participating in NFO Worldgroup survey research received a questionnaire to identify adults with incontinence. Based on stratified random sampling of identified incontinent women, 2310 women received a detailed questionnaire. RESULTS Among 1970 women with urinary incontinence symptoms, 38% had initiated a conversation with a physician about incontinence. In multivariate logistic regression analysis, some of the factors associated significantly with treatment seeking were symptom duration >3 years (OR 2.33, 95% CI 1.57-3.45), having a history of a noticeable accident (OR 1.41, 95% CI 1.06-1.87), worse disease-specific quality of life scores (OR 1.89, 95% CI 1.32-2.70), not being embarrassed to talk with a physician about urinary symptoms (OR 1.65, 95% CI 1.28-2.14), talking with others about urinary incontinence (OR 3.34, 95% CI 2.49-4.49), and keeping regular appointments for routine/preventive care (OR 2.25, 95% CI 1.54-3.29). CONCLUSIONS Less than half of community-dwelling adult U.S. women with symptoms of urinary incontinence have talked with a physician about urinary incontinence. In addition to duration of symptoms, factors associated with treatment seeking included the impact of incontinence on quality of life, lack of embarrassment about talking to a physician about urinary symptoms, and attitudes toward healthcare use. Concerns about the meaning of incontinence for overall and future health were important reasons for women choosing to seek treatment.

Fecal and urinary incontinence in primiparous women

OBJECTIVE: To prospectively investigate the relationship between anal sphincter tears and postpartum fecal and urinary incontinence. METHODS: The Childbirth and Pelvic Symptoms study was a prospective cohort study performed by the Pelvic Floor Disorders Network to estimate the prevalence of postpartum fecal and urinary incontinence in primiparous women: 407 with clinically recognized anal sphincter tears during vaginal delivery, 390 without recognized sphincter tears (vaginal controls), and 124 delivered by cesarean before labor. Women were recruited postpartum while hospitalized and interviewed by telephone 6 weeks and 6 months postpartum. We assessed fecal and urinary incontinence symptoms using the Fecal Incontinence Severity Index and the Medical, Epidemiological, and Social Aspects of Aging Questionnaire, respectively. Odds ratios were adjusted for age, race, and clinical site. RESULTS: Compared with the vaginal control group, women in the sphincter tear cohort reported more fecal incontinence (6 weeks, 26.6% versus 11.2%; adjusted odds ratio [AOR] 2.8, 95% confidence interval [CI] 1.8–4.3; 6 months, 17.0% versus 8.2%; AOR 1.9, 95% CI 1.2–3.2), more fecal urgency and flatal incontinence, and greater fecal incontinence severity at both times. Urinary incontinence prevalence did not differ between the sphincter tear and vaginal control groups. Six months postpartum, 22.9% of women delivered by cesarean reported urinary incontinence, whereas 7.6% reported fecal incontinence. CONCLUSION: Women with clinically recognized anal sphincter tears are more than twice as likely to report postpartum fecal incontinence than women without sphincter tears. Cesarean delivery before labor is not entirely protective against pelvic floor disorders. LEVEL OF EVIDENCE: II-3

Combined Behavioral and Drug Therapy for Urge Incontinence in Older Women

OBJECTIVE: The purpose of this study was to examine the effects of combining behavioral treatment and drug treatment for urge incontinence in community‐dwelling older women.

Urinary Incontinence in the Elderly: Bladder-Sphincter Biofeedback and Toileting Skills Training

Behavioral treatment of urinary incontinence was given to 39 elderly outpatients; 19 had stress incontinence, 12 detrusor motor instability, and 8 urge incontinence without instability. Biofeedback involving the bladder and sphincter was used to teach selective control of sphincter muscles or voluntary inhibition of detrusor contractions. Traditional behavioral methods used included habit training to gradually increase the voiding interval and relaxation training to cope with the urge to void. After an average 3.5 training sessions, patients with stress incontinence reduced the frequency of incontinent episodes an average of 82% (range, 55% to 100%). Patients with detrusor motor instability showed an average 85% improvement (range, 39% to 100%), and patients with urge incontinence reduced incontinence an average of 94% (range, 83% to 100%). Furthermore, 13 of the patients achieved total continence, and 19 had fewer than one accident per week after treatment.

Treatment seeking for urinary incontinence in older adults.

Objective: To examine treatment seeking for urinary incontinence among older adults and to identify characteristics associated with treatment‐seeking behavior.

Burden of stress urinary incontinence for community-dwelling women

OBJECTIVE The purpose of this study was to better understand the subjective bothersomeness of stress urinary incontinence symptoms and their impact on the quality of life of community-dwelling women. STUDY DESIGN We conducted a mail survey of 605 women in the United States who reported symptoms of stress urinary incontinence. RESULTS More than three fourths of the respondents reported their symptoms to be bothersome, with approximately 29% reporting their symptoms to be moderately to extremely bothersome. The odds of moderate-to-extreme bother decreased with age and increased with symptom severity. Concerns about social embarrassment were evident. CONCLUSION Stress urinary incontinence symptoms can impose a significant burden on the women who have them. The results reinforce the need for health care professionals to be proactive in questioning and educating patients about this common lower urinary tract symptom.

Changes in urinary and fecal incontinence symptoms with weight loss surgery in morbidly obese women.

OBJECTIVE: To examine changes in the prevalence and severity of urinary incontinence (UI) and fecal incontinence in morbidly obese women undergoing laparoscopic weight loss surgery. METHODS: In a prospective cohort study, 101 women (aged 20–55 years) with body mass index (BMI) of 40 or more underwent laparoscopic Roux-en-Y gastric bypass and were followed to 6 and 12 months. Presence, severity, and effect of UI were assessed using the Medical, Epidemiological, and Social Aspects of Aging Questionnaire, Urogenital Distress Inventory, and Incontinence Impact Questionnaire. Fecal incontinence was assessed by self-report of anal leakage. RESULTS: Mean BMI decreased from 48.9±7.2 presurgery to 35.3±6.5 at 6 months and 30.2±5.7 at 12 months postsurgery. Prevalence of UI decreased from 66.7% presurgery to 41.0% at 6 months and 37.0% at 12 months (P<.001; 95% confidence interval [CI] for change 18.6–40.0%). Reduction in prevalence of UI was significantly associated with decreases in BMI (P=.01). Among incontinent women who lost 18 or more BMI points, 71% regained urinary continence at 12 months. Medical, Epidemiological, and Social Aspects of Aging Questionnaire urge and stress scores decreased (both P<.001; 95% CI 0.5–1.85 and 2.71–5.34, respectively), as did scores on the Urogenital Distress Inventory (P<.001; 95% CI 8.31–16.21) and Incontinence Impact Questionnaire (P<.001; 95% CI 4.71–14.60), indicating reduction in severity. Prevalence of fecal incontinence (solid or liquid stool) decreased from 19.4% to 9.1% at 6 months and 8.6% at 12 months (P=.018; 95% CI 2.1–19.4%). CONCLUSION: Prevalence of UI and fecal incontinence decreased after bariatric surgery. Magnitude of weight loss was associated with reduction in UI prevalence, strengthening the inference that improvements are attributable to weight loss. LEVEL OF EVIDENCE: II
