Urinary incontinence in elite female athletes and dancers

A PERDA DE URINA É INFLUENCIADA PELA MODALIDADE ESPORTIVA OU PELA CARGA DE TREINO? UMA REVISÃO SISTEMÁTICA

RESUMO Atualmente, diversos estudos relatam incontinência urinária (IU) entre mulheres jovens nulíparas e fisicamente ativas. Contudo, alguns investigam a prevalência da IU de acordo com as modalidades esportivas, enquanto outros investigam a carga de treino. A finalidade do presente estudo foi verificar se a modalidade esportiva é mais determinante na prevalência de IU do que a carga de treino entre mulheres jovens nulíparas. Para esta revisão sistemática, três revisores independentes realizaram uma busca de publicações originais nas bases de dados PubMed, LILACS e SciELO, entre 1994 e 2015. Foram utilizadas como estratégia de busca as palavras-chave: urinary incontinence AND (physical activity OR women OR nulliparous OR athletes), registradas na MeSH e no DeCS. Foram incluídos apenas estudos originais publicados nas línguas português, inglês e espanhol, que verificaram a IU em mulheres nulíparas, atletas ou praticantes de atividade física. Foram selecionados 873 estudos, mas somente dez artigos satisfizeram os critérios de inclusão e exclusão. Todos os artigos foram do tipo transversal, dos quais quatro relacionaram a IU com as modalidades esportivas, cinco verificaram a carga de treino com a perda de urina e um estudo verificou ambos os aspectos. Foi encontrada uma alta taxa de prevalência de IU entre atletas. Parece haver evidência de que as atividades que exigem salto, aterrissagem longa e corrida são as mais propensas a provocar perda de urina. Além disso, a maior carga de treino parece estar associada com a quantidade de urina perdida. Esta revisão evidencia as altas taxas de IU em praticantes de grandes cargas de treinamento associadas a esportes com salto, especialmente entre atletas. Contudo, ainda não há resposta para qual fator esportivo é mais determinante para a perda de urina entre mulheres nulíparas.

Effectiveness of pelvic floor muscle training in treating urinary incontinence in women: A current review

OBJECTIVE

To analyse the content of various published studies related to physical exercise and its effects on urinary incontinence and to determine the effectiveness of pelvic floor training programmes.

METHOD

We conducted a search in the databases of PubMed, CINAHL, the Cochrane Plus Library, The Cochrane Library, WOS and SPORTDiscus and a manual search in the Google Scholar metasearcher using the search descriptors for documents published in the last 10 years in Spanish or English. The documents needed to have an abstract or complete text on the treatment of urinary incontinence in female athletes and in women in general.

RESULTS

We selected 3 full-text articles on treating urinary incontinence in female athletes and 6 full-text articles and 1 abstract on treating urinary incontinence in women in general. The 9 studies included in the review achieved positive results, i.e., there was improvement in the disease in all of the studies.

CONCLUSIONS

Physical exercise, specifically pelvic floor muscle training programmes, has positive effects on urinary incontinence. This type of training has been shown to be an effective programme for treating urinary incontinence, especially stress urinary incontinence.

Influence of parity, type of delivery, and physical activity level on pelvic floor muscles in postmenopausal women

[Purpose] The aim of the present study was to assess the influence of parity, type of delivery, and physical activity level on pelvic floor muscles in postmenopausal women. [Subjects and Methods] This was an observational analytic cross-sectional study with a sample of 100 postmenopausal women, aged between 45 and 65 years, divided into three groups according to menopausal stage: hysterectomized and early and late postmenopause. Patients were assessed for sociodemographic and gyneco-obstetric factors and subjected to a muscle strength test and perineometry. Descriptive statistics, ANOVA, Kruskal-Wallis and multiple regression were applied. [Results] The results showed homogeneity in sociodemographic and anthropometric characteristics. There was no difference in pelvic floor muscle function among the three groups. Type of delivery, parity and physical activity level showed no influence on muscle function. [Conclusion] The findings demonstrate that parity, type of delivery, and physical activity level had no influence on pelvic floor muscle pressure in postmenopausal women. One hypothesis to explain these results is the fact that the decline in muscle function in postmenopausal women is related to the female aging process.

Prevention of pelvic floor disorders: international urogynecological association research and development committee opinion

INTRODUCTION AND HYPOTHESIS

Pelvic floor disorders (PFD), including urinary incontinence, anal incontinence, and pelvic organ prolapse, are common and have a negative effect on the quality of life of women. Treatment is associated with morbidity and may not be totally satisfactory. Prevention of PFDs, when possible, should be a primary goal. The purpose of this paper is to summarise the current literature and give an evidence-based review of the prevention of PFDs METHODS: A working subcommittee from the International Urogynecological Association (IUGA) Research and Development (R&D) Committee was formed. An initial document addressing the prevention of PFDs was drafted, based on a review of the English-language literature. After evaluation by the entire IUGA R&D Committee, revisions were made. The final document represents the IUGA R&D Committee Opinion on the prevention of PFDs.

RESULTS

This R&D Committee Opinion reviews the literature on the prevention of PFDs and summarises the findings with evidence-based recommendations.

CONCLUSIONS

Pelvic floor disorders have a long latency, and may go through periods of remission, thus making causality difficult to confirm. Nevertheless, prevention strategies targeting modifiable risk factors should be incorporated into clinical practice before the absence of symptomatology.

Physical activity and the pelvic floor

Pelvic floor disorders are common, with 1 in 4 US women reporting moderate to severe symptoms of urinary incontinence, pelvic organ prolapse, or fecal incontinence. Given the high societal burden of these disorders, identifying potentially modifiable risk factors is crucial. Physical activity is one such potentially modifiable risk factor; the large number of girls and women participating in sport and strenuous training regimens increases the need to understand associated risks and benefits of these exposures. The aim of this review was to summarize studies reporting the association between physical activity and pelvic floor disorders. Most studies are cross-sectional and most include small numbers of participants. The primary findings of this review include that urinary incontinence during exercise is common and is more prevalent in women during high-impact sports. Mild to moderate physical activity, such as brisk walking, decreases both the odds of having and the risk of developing urinary incontinence. In older women, mild to moderate activity also decreases the odds of having fecal incontinence; however, young women participating in high-intensity activity are more likely to report anal incontinence than less active women. Scant data suggest that in middle-aged women, lifetime physical activity increases the odds of stress urinary incontinence slightly and does not increase the odds of pelvic organ prolapse. Women undergoing surgery for pelvic organ prolapse are more likely to report a history of heavy work than controls; however, women recruited from the community with pelvic organ prolapse on examination report similar lifetime levels of strenuous activity as women without this examination finding. Data are insufficient to determine whether strenuous activity while young predisposes to pelvic floor disorders later in life. The existing literature suggests that most physical activity does not harm the pelvic floor and does provide numerous health benefits for women. However, future research is needed to fill the many gaps in our knowledge. Prospective studies are needed in all populations, including potentially vulnerable women, such as those with high genetic risk, levator ani muscle injury, or asymptomatic pelvic organ prolapse, and on women during potentially vulnerable life periods, such as the early postpartum or postoperative periods.

AVALIAÇÃO DO ASSOALHO PÉLVICO DE ATLETAS: EXISTE RELAÇÃO COM A INCONTINÊNCIA URINÁRIA?

Introdução O assoalho pélvico feminino é formado por um conjunto de músculos, fáscias e ligamentos que sustentam os órgãos pélvicos (bexiga, ânus e vagina). A lesão destas estruturas, devido à idade avançada e parto podem levar à incontinência urinária. Entretanto, ainda não se sabe se o exercício de alta intensidade é capaz de lesar este conjunto músculo-aponevrótico, levando à incontinência urinária. Objetivo Comparar a capacidade de contração dos músculos do assoalho pélvico entre mulheres sedentárias e atletas de elite, e verificar se existe associação com a ocorrência de incontinência urinária durante a atividade física. Métodos Estudo caso-controle que incluiu 93 mulheres (49 atletas e 44 sedentárias) convidadas a responder o questionário "International Consultation on Incontinence Questionnaire - Short Form" e realizar avaliação funcional do assoalho pélvico. As atletas (grupo caso) eram praticantes de corrida de longa distância, basquete e ginástica olímpica. As sedentárias (grupo controle) realizavam menos de 150 minutos por semana de atividades moderadas ou vigorosas. A aferição da pressão de contração foi feita por meio de um perineômetro digital de precisão. Resultados Os grupos foram homogêneos quanto à idade e índice de massa corpórea. As atletas apresentaram maiores valores de pressão vaginal máxima (70,1±2,4 cmH2O) quando comparadas às sedentárias (34,3±1,7 cmH2O), (p<0,001). As atletas praticantes de basquete tiveram os maiores valores da pressão vaginal máxima (77,2 cmH2O) quando comparadas às ginastas (65,5 cmH2O) e corredoras (65,4 cmH2O). A prevalência de incontinência urinária nas atletas foi de 76% e somente 16% nas sedentárias (p=0,005). Conclusão Embora a capacidade de contração do assoalho pélvico em atletas de elite seja superior às sedentárias, a prevalência de incontinência urinaria foi elevada neste grupo de praticantes de esporte de alto rendimento e alto impacto.

[Urinary incontinence in non-professional female marathon runners]

OBJECTIVE

To determine the prevalence of urinary incontinence within a population of female recreational runners during a marathon.

METHODS

Observational study carried on a marathon from the analysis of questionnaire handed to the participants before the beginning of the marathon. The questionnaire was handed to 800 participants and among them, 517 (64.6%) agreed to fill it. Among the participants, 268 (52.4%) were marathon runners and 243 (47.5%) were relay runners.

RESULTS

Mean age of the runners was 41.1 (±9.7), 479 (93.7%) of them were caucasian, mean body mass index was 20,7 (±1.9) kg/m(2) and 173 (34%) were nulliparous. Among responders, 157 (30.7%) runners declared to have urinary incontinence symptoms (any circumstances). Among 157 runners who declared an urinary incontinence, 83 (52,9%) presented with urinary leaks during the running. In half of the cases, these urinary leaks usually arose at the end of race. Urinary incontinence during coughing, sneezing or laughing was reported by 96/517 (18,5%) women. The prevalence of urge urinary incontinence was 63/517 (12%). Concerning the frequency of urinary incontinence, 39/517 (7.5%) women reported at least once weekly. For urinary incontinence bother, scores on the Visual Analogue Scale (VAS 0 to 100) was 1.6 (±1.7).

CONCLUSION

In this series, the prevalence of urinary incontinence was 30.7% within a population of female recreational runners. This rate seems to be similar to the current prevalence in the general population.

Lifetime physical activity and female stress urinary incontinence

OBJECTIVE

We sought to estimate whether moderate/severe stress urinary incontinence (SUI) in middle-aged women is associated with overall lifetime physical activity (including leisure, household, outdoor, and occupational), as well as lifetime leisure (recreational), lifetime strenuous, and strenuous activity during the teen years.

STUDY DESIGN

Recruitment for this case-control study was conducted in primary-care-level family medicine and gynecology clinics. A total of 1538 enrolled women ages 39-65 years underwent a Pelvic Organ Prolapse Quantification examination to assess vaginal support. Based on Incontinence Severity Index scores, cases had moderate/severe and controls had no/mild SUI. We excluded 349 with vaginal descent at/below the hymen (pelvic organ prolapse), 194 who did not return questionnaires, and 110 with insufficient activity data for analysis. In all, 213 cases were frequency matched 1:1 by age group to controls. Physical activity was measured using the Lifetime Physical Activity Questionnaire, in which women recall activity from menarche to present. We created separate multivariable logistic regression models for activity measures.

RESULTS

SUI odds increased slightly with overall lifetime activity (odds ratio [OR], 1.20 per 70 additional metabolic equivalent of task-h/wk; 95% confidence interval [CI], 1.02-1.41), and were not associated with lifetime strenuous activity (OR, 1.11; 95% CI, 0.99-1.25). In quintile analysis of lifetime leisure activity, which demonstrated a nonlinear pattern, all quintiles incurred about half the odds of SUI compared to reference (second quintile; P = .009). Greater strenuous activity in teen years modestly increased SUI odds (OR, 1.37 per 7 additional h/wk; 95% CI, 1.09-1.71); OR, 1.75; 95% CI, 1.15-2.66 in sensitivity analysis adjusting for measurement error. The predicted probability of SUI rose linearly in women exceeding 7.5 hours of strenuous activity/wk during teen years. Teen strenuous activity had a similar effect on SUI odds when adjusted for subsequent strenuous activity during ages 21-65 years.

CONCLUSION

In middle-aged women, a slight increased odds of SUI was noted only after substantially increased overall lifetime physical activity. Increased lifetime leisure activity decreased and lifetime strenuous activity appeared unrelated to SUI odds. Greater strenuous activity during teen years modestly increased SUI odds.

Volume of training and the ranking level are associated with the leakage of urine in young female trampolinists

OBJECTIVES

The aim of this study was to investigate in young nulliparous female trampolinists the hypothetical associations between the level of athletic performance and the volume of training with urine leakage.

DESIGN

Cross-sectional cohort study.

SETTING

Professional trampolinists.

PARTICIPANTS

Twenty-two female athletes participating in a trampoline national championship were included in this study.

ASSESSMENT OF RISK FACTORS

The associations for player-related performance variables were evaluated using Spearman rank correlation and Kruskal-Wallis H test verified the differences between the tertiles.

MAIN OUTCOME MEASURES

Rate of urinary incontinence (UI) among young athletes and the relationship with the athletic performance. Screening was performed through a questionnaire. This included the demographic sample characterization, the assessment of training volume, and the athletes' ranking in the championship. Additionally, it included the International Consultation on Incontinence Questionnaire Short-Form (ICIQ-UI-SF) to assess the leakage.

RESULTS

About 72.7% of the participants reported that they experienced urine leakage during trampoline practice and described that the episodes of leakage started after the beginning of the trampoline. Significant associations between the athletic performance and the training volume were observed with the severity of incontinence. Dividing the sample in tertiles of training volume, it was observed that the third tertile was the one with greatest impact of incontinence on their quality of life (ICIQ score).

CONCLUSIONS

The results confirm a high frequency of UI in young trampolinists and reveal a clear identification of the athletes' ranking and the training volume as risk factors to develop and worsen urine loss.

CLINICAL RELEVANCE

Special attention from team physicians and trainers is required for this athletes' problem that is often hidden by shame. In addition, female athletes practicing high-impact sports should be informed about the risk to develop pelvic floor muscles dysfunction and should be encouraged to seek help from health professionals to minimize or even eliminate the urine incontinence.

Prevalence of stress urinary incontinence in elite female endurance athletes

The goal of the study was to assess the prevalence of stress urinary incontinence in a group of elite female endurance athletes, as professional sport is one of the risk factors for stress urinary incontinence. SUI rates in the groups of female cross-country skiers and runners were compared to determine whether the training weather conditions like temperature and humidity influenced the prevalence of urinary incontinence. An anonymous questionnaire was distributed among 112 elite female athletes ie., 57 cross-country skiers and 55 runners. We used a short form of the Urogenital Distress Inventory (UDI-6) to assess the presence of SUI symptoms and the level of urogenital distress. Only women who had been practicing sport professionally for at least 3 years, on an international and national level, were included in the research. The study group consisted of 76% nulliparous and 24% parous women. 45.54% of all participants reported leakage of urine associated with sneezing or coughing which indicates stress urinary incontinence. 29.46% were not bothered by the urogenital distress symptoms. 42.86% of the participants were slightly bothered by the symptoms, 18.75% were moderately bothered, 8.04% were significantly bothered and 0.89% were heavily bothered. The absence of statistically significant differences between both groups seems to indicate that training weather conditions did not influence the prevalence of SUI in elite female endurance athletes.

Health in older women athletes

Physical activity has been identified as a protective factor against a wide spectrum of diseases, but little is known about the link between older women's health and their professional involvement in sport in the past. The aim of this narrative review is to characterize and summarize the available data concerning the influence of physical activity on morbidity and mortality in former female athletes. Concerning bone health, it seems that physical activity in the past can be protective against osteoporosis in postmenopausal women, but these data come from observational studies only. Also the cardiovascular system appears to benefit in older women from regular sport in the past. This refers mainly to better heart efficiency, and improved endothelial function and metabolic profile. The incidence of different types of neoplasms, especially breast cancer, is also decreased in former athletes. Professional sport, on the other hand, acts negatively on the pelvic floor and is a risk factor for urinary incontinence. The overall effect on mortality is difficult to assess, because of many parameters, such as the sport's intensity, variety of the sport and exposure to extreme danger in some disciplines. Also, caution should be kept in interpretation of the data because of the shortage of well-designed studies.

Reeducation of pelvic floor muscles in volleyball athletes

Objective: to verify the effectiveness of the pelvic floor muscles rehabilitation program (PFMRP) in female volleyball athletes, analyzing the amount and frequency of urinary leakage. Methods: experimental study. The sample consisted of 32 female athletes from Famalicão Athletic Volleyball Club (Portugal). The athletes were selected by convenience and distributed randomly into two groups: experimental group (EG = 16 athletes) and the control group (CG = 16 athletes). The EG underwent PFMRP for three months. The PFMRP was the awareness and identification of the pelvic floor muscles (PFM), pre-timed PFM contraction prior to occasions of increased intra-abdominal pressure, and 30 daily contractions of MPP at home. The CG had only access to the pamphlet. The assessment instruments included the questionnaires, the Pad Test (amount of urinary leakage) and frequency record of urinary leakage (7-day diary) before and after PFMRP. Results: the amount of urine leakage decreased in 45.5% of athletes under PFMRP intervention, and in 4.9% of athletes in CG, with statistical differences between the groups (p < 0.001). The reduction in the frequency of urinary leakage was 14.3% in EG, and 0.05% in CG, a statistically significant difference between the groups (p < 0.001). Conclusion: PFMRP in this study was effective to reduce stress urinary incontinence in female volleyball athletes. The program allowed significant improvement of symptoms of quantity and frequency of urinary leakage.

[Sport and urinary incontinence in women]

Women are more attentive to their physical appearance and a quarter of French women use to practice a regular physical activity. Benefits of sport on general health are recognized. However, sport may be the cause of various diseases when it is poorly chosen or improperly performed. In literature, intensive exercise is a risk factor for urinary incontinence, defined as "the complaint of any involuntary leakage of urine". It is essentially stress urinary incontinence, occurring because of the phenomenon of intrabdominal hyperpressure, inherent with certain activities, and excess capacity of sphincters. Some sports are more risky than others, and high-level sportswomen are the most exposed. Health professionals must invest in information, screening, prevention, counseling and treatment track athletes So, the general practitioner and the doctor of sports play a vital role in informing, screening, prevention, therapeutic and monitoring of sportswomen. Better information is needed because according to the severity of incontinence and its impact, there are simple, effective, more or less invasive treatment options. The aim of this study was to establish an inventory of scientific knowledge and to improve the management of these patients.

Barriers to Physical Activity in Women

Despite the clear benefits of physical activity for women, few women obtain the recommended levels of physical activity. To address adherence to physical activity in this group, it is important to understand the barriers to physical activity that affect women. These barriers may include lack of time; anticipated lack of enjoyment; self-consciousness about body size, shape, and physical activity ability; and urinary incontinence. By addressing barriers to physical activity, health care providers may experience greater success in their efforts to increase physical activity in their female patients.

Urinary incontinence in physically active women and female athletes

A literature review was performed on the topic of urinary incontinence during physical activity and sports. This paper reviews the prevalence, risk factors, pathophysiology and treatment modalities of urinary incontinence in physically active women and female athletes. Urinary incontinence affects women of all ages, including top female athletes, but is often under-reported. The highest prevalence of urinary incontinence is reported in those participating in high impact sports. Pelvic floor muscle training is considered the first-line treatment, although more research is needed to determine optimal treatment protocols for exercising women and athletes. Trainers, coaches and other athletes' caregivers should be educated and made aware of the need for proper urogynaecological assessment.

Pelvic floor muscle exercise as the best stress urinary incontinence prevention method in women practising competitive sport

Exercises in stress urinary incontinence (SUI) cover Pelvic Floor Muscle Exercises (PFME), also known in literature as Pelvic Floor Muscle Training (PFMT) or Kegel exercises; isometric exercises, exercises of the abdominal and gluteal muscles and of the adductor of thigh, respiratory exercises carried out through the abdominal tract, exercises in water. In persons with urinary incontinence, the interaction between the pelvic floor muscles and the transverse abdominal muscle is impaired, suggesting a significant role of this muscle in urinary continence. Consequently, a moderate training, e.g. including exercises of Pilates method, may be part of the therapy. Stress urinary incontinence is a frequent occurrence among women practising competitive sport. In the review article we have presented the incidence of stress urinary incontinence in sportswomen, risk factors and physiotherapeutic treatment. We have paid specific attention to the prevention of stress urinary incontinence in female athletes.

Assessment of pelvic floor muscle pressure in female athletes

OBJECTIVE

To evaluate the pressure of the pelvic floor muscles in female athletes and the associated signs and symptoms of stress urinary incontinence.

DESIGN

A prospective observational study.

SETTING

An academic institution, primary level of clinical care.

PARTICIPANTS

Forty women between 18 and 30 years of age divided into 4 groups: 10 volleyball players, 10 handball players, 10 basketball players, and 10 nonathletes.

METHODS

The measurement of intracavity pressure was performed with use of a perineometer. The volunteers were instructed to perform 3 maximum isometric contractions of the perineum, held for 4 seconds. Data regarding specific training and urinary symptoms were collected through a questionnaire.

MAIN OUTCOME MEASUREMENTS

Statistical analysis was performed by analysis of variance, with a significance level of 5%. The Spearman correlation was used to verify the degree of association between variables related to training, urinary symptoms, and perineal pressure.

RESULTS

The average (standard deviation) perineal pressure for nonathletes was 6.73 ± 1.91 mm Hg. The average perineal pressure for handball players was 5.55 ± 1.43 mm Hg; for volleyball players, 4.36 ± 1.43 mm Hg; and for basketball players, 3.65 ± 1.35 mm Hg. Statistically significant differences were found in the perineal pressure of volleyball (P = .009) and basketball players (P = .039) compared with nonathletes. The number of games per year, strength training, and on-court workout correlated significantly with perineal pressure (Spearman correlation coefficient [Rs] of -0.512 for the 3 variables). Urine leakage through effort and nocturia correlated moderately with perineal pressure (Rs of -0.51 and -0.54, respectively). A strong correlation was found between urinary frequency and perineal pressure (Rs of -0.85).

CONCLUSIONS

Analysis of these data suggests that perineal pressure is decreased in female athletes compared with nonathlete women. A lower perineal pressure correlates with increased symptoms of urinary incontinence and pelvic floor dysfunction.

Prevalência, tipologia e sintomas de gravidade da incontinência urinária em mulheres idosas segundo a prática de atividade física

INTRODUÇÃO: A prática de atividade física (AF) é importante para a população idosa, graças aos beneficios biopsicossociais. A incontinência urinária (IU) também vem sendo analisada, pois o avanço da idade é um fator de risco importante na sua ocorrência. OBJETIVO: Verificar a prevalência, a tipologia e os sintomas de gravidade da IU entre mulheres idosas segundo a prática de AF regular. MATERIAIS E MÉTODOS: Participaram deste estudo 209 idosas, divididas em três grupos, segundo o nível de AF. Foram coletados dados referentes à presença, tipologia, duração e gravidade dos sintomas da IU. Utilizou-se estatística descritiva e inferencial, por meio dos testes Qui-Quadrado, Mann-Whitney e Análise de Variância, conforme os grupos de variáveis. Adotou-se nível de significância de 5%. RESULTADOS: A presença de IU na amostra total foi de 33,3%, sendo a menor prevalência entre as idosas mais ativas (28,9%). Quanto à tipologia, 28,7% apresentaram IU de esforço (IUE), 14,8% IU de urgência (IUU) e 10,5% IU mista (IUM). A presença de IUU (p = 0,05) e IUM (p = 0,04) associou-se com o grupo de mulheres sedentárias. A prática de ginástica associou-se com a ausência de IU (p = 0,003). Em 43,5% da amostra, o início dos sintomas de gravidade deu-se após a menopausa. A retenção de urina sem dificuldade associou-se com a prática de AF (p = 0,029). CONCLUSÃO: A menor incidência de IU entre as idosas muito ativas pode ser atribuída aos benefícios da AF moderada ao mecanismo de continência. Além disso, a prática de exercícios físicos também parece minimizar os sintomas de urgência miccional.

Exploring the association between lifetime physical activity and pelvic floor disorders: study and design challenges

BACKGROUND

One in four women has moderate to severe symptoms of at least one pelvic floor disorder. Lifetime physical activity, a modifiable risk factor, may theoretically predispose women to, or protect them from, developing pelvic floor disorders. It is neither feasible nor ethical to test this association using the most rigorous (level I) study design.

PURPOSE

The aim of this manuscript is to describe the methods for the PHysical ACtivity Study (PHACTS), which encompasses two case-control studies and the development of a registry, and to describe challenges and solutions to study progress to date. For each of the case-control studies, the primary aims are to determine, compared to controls with neither pelvic organ prolapse nor urinary incontinence, whether 1) pelvic organ prolapse or 2) stress urinary incontinence is associated with a) increased or decreased current leisure activity or b) increased or decreased overall lifetime activity (including leisure, household, outdoor, and occupational) measured in MET-hours per week, as well as in strenuous hours per week.

METHODS

To obtain 175 pelvic organ prolapse cases, 175 stress urinary incontinence cases, and an equal number of age, body mass index and recruitment site matched controls, we plan to enroll 1500 women from about 20 primary care level clinics.

RESULTS

We have encountered various challenges leading to lessons learned about minimizing bias, recruitment from community clinics, the lifetime physical activity instrument used, and data management.

CONCLUSIONS

Our experiences can help guide future investigators studying risk factors, particularly physical activity, and pelvic floor disorders.

Prevalence study of stress urinary incontinence in women who perform high-impact exercises

INTRODUCTION

Stress urinary incontinence is a frequent complaint in medical offices and studies have shown that women who practice high impact sports develop its symptoms.

OBJECTIVE

To evaluate the prevalence of stress urinary incontinence in women who attend gyms and perform high impact exercises and correlate it with women who do not attend gyms.

METHOD

Prospective comparative study in which 488 nulliparous women of normal weight were divided into a Study Group, composed of women who attended gyms, and a Comparative Group, composed of women who did not attend gyms. Three questionnaires were used for the evaluation of stress urinary incontinence and the results of the ICIQ-SF questionnaire were used to compare the groups.

RESULTS

There was a significant difference between groups on the ICIQ-SF. The average in the Study Group was 1.68 (+ 3.46) and in the Comparative Group the average was 1.02 (+ 2.69) (p = 0.006).

CONCLUSION

Women who attend gym and perform high impact exercises have a higher prevalence of urinary incontinence symptoms, independent of the exercise modality, than women who do not perform any high impact exercise.

A healthy bladder: a consensus statement

A panel of experts in urology, urogynecology, nursing, and behavioral therapy convened in 2010 to discuss the importance of a healthy bladder on overall health. They determined that a consensus statement was necessary to raise awareness among the general public, healthcare providers, payors, and policymakers, with the goals of minimizing the impact of poor bladder health and stimulating primary prevention of bladder conditions. In this statement, 'healthy' bladder function is described, as well as internal and external factors that influence bladder health. It is suggested that primary prevention strategies should be aimed at providing education regarding normal lower urinary tract structures and functioning to the public, including patients and healthcare providers. This education may promote the achievement of optimal bladder health by increasing healthy bladder habits and behaviors, awareness of risk factors, healthcare seeking, and clinician engagement and reducing stigma and other barriers to treatment. Promoting optimal bladder health may reduce the personal, societal and economic impact of bladder conditions, including anxiety and depression and costs associated with conditions or diseases and their treatment. While adopting healthy bladder habits and behaviors and behaviors may improve or maintain bladder health, it is important to recognize that certain symptoms may indicate the presence of conditions that require medical attention; many bladder conditions are treatable with a range of options for most bladder conditions. Lastly, the authors propose clinical directives based on persuasive and convergent research to improve and maintain bladder health. The authors hope that this statement will lead to promotion and achievement of optimal bladder health, which may improve overall health and help minimize the effects of bladder conditions on the public, healthcare professionals, educators, employers, and payors. The advisors are in consensus regarding the recommendations for improving and maintaining bladder health presented herein.

Impact of high-level sport practice on anal incontinence in a healthy young female population

BACKGROUND

Regular physical activity usually confers health benefits, but high-level sport may induce harmful outcomes, such as pelvic floor dysfunction. Urinary incontinence (UI) was previously documented, but few data are available about anal incontinence (AI) in female athletes. Our aim was to determine the role of high-level sport practice on AI in a young, healthy female population.

METHODS

In this cross-sectional study, we included women aged 18-40 years. Self-administered questionnaires were delivered to each female volunteer. Two groups were defined: (1) intensive sport (IS) group: high-level sport (>8 hours weekly), and (2) nonintensive sport (NIS) group: all other subjects.

RESULTS

Of the 393 women enrolled, 169 were in the IS group and 224 were in the NIS group. Women of the IS group were significantly younger than the others (21.74±4.28 vs. 24.87±5.61 years, p<0.001) and had less births (0.07±0.31 vs. 0.20±0.62, p=0.005). The prevalence of AI was statistically higher in the IS group than in the NIS group (14.8% vs. 4.9%, p=0.001), as was UI (33.1% vs. 18.3%, p=0.001). Multivariate analysis showed that IS practice (odds ratio [OR] 2.99, 95% confidence interval [CI] 1.29-6.87, p=0.010) and body mass index (BMI) (OR 1.14, 95% CI 1.01-1.28, p=0.033) were significantly linked to AI when taking into account major confounding factors (age and births). In the IS group, AI was mainly represented by loss of flatus in 84%.

CONCLUSIONS

High-level sport appears to be a significant independent risk factor for AI in healthy young women. These results suggest that preventive measures, such as pelvic floor muscle training, may be proposed for this young population.

Estudo comparativo da capacidade de contração do assoalho pélvico em atletas de voleibol e basquetebol

As modalidades esportivas de alto impacto podem produzir um aumento exagerado e frequente na pressão intra-abdominal, um dos fatores desencadeadores da incontinência urinária de esforço (IUE) em atletas. Foi realizado um estudo com 20 atletas, sendo 10 de basquetebol e 10 de voleibol, do tipo quantitativo, observacional, transversal e comparativo, no qual foi comparada a capacidade de contração do assoalho pélvico (AP) entre atletas de voleibol e basquetebol, e então correlacionadas com sintomas de IUE. A avaliação das atletas foi composta por um questionário, a avaliação funcional do assoalho pélvico (AFA) e avaliação da capacidade de contração do AP através do Biofeedback Eletromiográfico Fênix®. Após a avaliação, não foi observada diferença estatisticamente significante com relação à capacidade de contração do assoalho pélvico entre atletas de basquetebol e voleibol; porém, ambas as modalidades apresentaram atletas com relatos de perda involuntária de urina mediante esforço físico, com maior proporção no grupo de atletas de basquetebol.

The impact of urinary stress incontinence in young and middle-age women practising recreational sports activity: an epidemiological study

OBJECTIVES

To evaluate the prevalence of urinary stress incontinence (USI) in menstruating women practising recreational sports activity, to detect specific sports with a stronger association with urinary incontinence (UI) and to evaluate risk factors possibly related to this condition.

DESIGN

Epidemiological study.

SETTING

Non-competitive sports organisations in the province of Varese, Italy.

PARTICIPANTS

679 women of fertile age, practising recreational sports activity.

INTERVENTION

Anonymous questionnaire on UI.

MAIN OUTCOME MEASUREMENTS

The questionnaire included questions about patients' general characteristics, occurrence of UI in relation to sport or daily general activities, time of onset of this condition, frequency of leakage episodes, correlation of incontinence with types of movements or sports, subjective impression of being limited on such occasions and/or necessity to modify the type of sport.

RESULTS

UI was reported by 101 women (14.9%). Of these, 32 (31.7%) complained of UI only during sports activity, 48 (47.5%) only during daily life and 21 (20.8%) in both circumstances. Body mass index and parity were significantly associated with the risk of UI. Looking at the different sports activities, a higher rate of incontinence was found in women participating in basketball (16.6%), athletics (15%), and tennis or squash (11%). 10.4% of women abandoned their favourite sport, because of USI, and a further 20% limited the way they practised their favourite sport to reduce leakage episodes.

CONCLUSIONS

Female UI affects a significant proportion of young women practising non-competitive sports activity; it can cause abandonment of the sport or limitation of its practice.

[Urinary incontinence among physical education students]

Urinary incontinence (UI) is seen as a problem that affects older multiparous women. Little attention has been given to identifying UI in groups of younger or nulliparous women. This study verified the prevalence of UI and the characteristics of urinary loss among young nulliparous female physical education students. Data collection was performed using a questionnaire. Of all 95 students, 61.1% answered the questionnaire. The average age was 21.4 years and 20.7% stated having presented involuntary urine loss. In 75% of cases, urinary loss occurred during sports activities. The students who had experienced urinary loss rated the problem with a 2.3 average score (ranging form 0 to 6), with 0 being no problem and 10 being a serious problem. It is concluded that urinary loss during exercise, though relatively frequent, is not considered a relevant issue for the physical education students.

Feasibility of using a computer modeling approach to study SUI Induced by landing a jump

Stress urinary incontinence (SUI) occurs due to anatomic and/or neurologic factors involving connective tissues, muscles and nerves. Although SUI is more common in post-menopausal and multiparous women, studies have also shown a high prevalence of SUI in young, physically fit female athletes. With a goal toward dynamic subject-specific mechanical characterization of the interaction between anatomical structures during physical activities that elicit SUI in females during physical or daily activities, a computer aided design (CAD)-based computer model of the female pelvis has been developed to test the feasibility of the computer modeling approach in understanding the measurable differences between stress-continent and stress-incontinent women. In the present study, a fluid-structure interaction analysis was conducted by using the finite element (FE) analysis technique based on the CAD-based computer model of the female pelvis to investigate the urine leakage in females during jumping. To the best of our knowledge, this is the first application of a fluid-structure interaction FE analysis approach in understanding the mechanisms of SUI in females. Through a series of computer simulations, the effects of varying impact forces determined by jumping height and bladder volume were investigated. The dynamic computer simulation results revealed that jumping heights have a significant influence on the volume of urine leakage caused by the landing impact of jumping. Bladder volume did not have a significant influence on leakage when the jumping heights were smaller than 1 ft, which indicates that normal walking (corresponds to a jumping height smaller than 0.1 ft) is not the primary cause of urine leakage for healthy females. The computer simulation results also showed that the deformation difference between the anterior and posterior portion of the female pelvis causes opening of the urethra and resultant urine leakage. The present study demonstrates the feasibility of using a computer modeling approach to study female SUI during physical and daily activities.

[Pelvic floor disorders]

Fecal and urinary incontinence are frequently associated, together with pelvic organ prolapse. The most important risk factors for pelvic floor disorders are vaginal delivery and chronic constipation. Irrespective of the symptom prompting the patient to seek medical attention and the specialist consulted, symptoms in other compartments must be investigated because patients rarely report them spontaneously. Patients with pelvic floor disorders should be evaluated by a multidisciplinary group of specialists. Complete evaluation includes urodynamics, anal manometry, endoanal ultrasonography and neurophysiologic study of the pelvic floor and is recommended in most patients, given that pelvic floor disorders have a complex and multifactorial pathophysiology and that all anatomic and functional abnormalities must be detected to provide the most appropriate treatment. Conservative treatment resolves or improves the problem in a large proportion of patients with mild-to-moderate symptoms. Surgery should be indicated in selected patients with careful evaluation to identify preoperatively all anatomical and functional defects that can be surgically corrected. The identification of risk factors and better knowledge of the prevalence and pathophysiology of this health problem will allow preventive strategies to be established and improve therapeutic outcomes.

Incontinência urinária e a prática de atividades físicas

A incontinência urinária é definida como "toda perda involuntária de urina". Ela atinge com maior freqüência mulheres e é causada principalmente por partos e gestações que podem lesar os músculos responsáveis pela continência na mulher. É muito comum mulheres que praticam atividades físicas e esportes apresentarem incontinência. Muitas dessas mulheres abandonam suas atividades para evitar perder urina durante essa prática, pois essa perda causa vergonha, constrangimento, além de interferir no desempenho durante o exercício. Inexistem pesquisas na área da educação física que discutam esse tema. O objetivo deste estudo consistiu de uma revisão bibliográfica acerca da incontinência urinária, analisando sua relação com atividades físicas e esportivas por mulheres, o impacto causado pela incontinência nessa prática, e de que forma o profissional de educação física pode contribuir com essas mulheres para uma prática mais segura e confortável. Os dados da literatura a respeito desse tema são muito recentes, mas suficientes para evidenciar que a prática de atividades físicas e esportivas constituídas de exercícios que exijam muito esforço e alto impacto pode levar ao desenvolvimento da incontinência urinária. As mulheres que não abandonam suas atividades por causa da incontinência utilizam algumas estratégias para prevenir a perda de urina, como o uso de absorventes e restrição hídrica. O profissional de educação física tem um papel fundamental na orientação adequada de exercícios, transformando essa prática numa intervenção preventiva da incontinência urinária entre mulheres fisicamente ativas.

Pelvic floor function in elite nulliparous athletes

OBJECTIVE

There is preliminary evidence linking long-term participation in high-impact exercise with poor performance in labor and increased incidence of stress urinary incontinence, which may be due to altered pelvic floor function. Recent work has shown that HIFIT (high-impact, frequent intense training) athletes have an increased cross-sectional area of the levator ani muscle group as visualized using magnetic resonance imaging (MRI). The aim of this study was to further characterize pelvic floor muscle function and pelvic organ descent in a nulliparous athletic population and compare it with non-athletic controls matched for age and body mass index, using three-dimensional/four-dimensional (3D/4D) pelvic floor ultrasound imaging.

METHODS

In this prospective comparative study translabial ultrasound imaging was used to assess pelvic floor anatomy and function in 46 nulliparous female volunteers (aged 19-39 years), 24 HIFIT and 22 controls. Two-dimensional (2D) and 3D translabial ultrasonography was performed on all subjects, after voiding and in the supine position. Descent of the pelvic organs was assessed on maximum Valsalva maneuver, whilst volume datasets were acquired at rest, during pelvic floor muscle contraction and during a Valsalva maneuver. Participants performed each maneuver at least three times and the most effective was used for evaluation.

RESULTS

HIFIT athletes showed a higher mean diameter of the pubovisceral muscle (0.96 cm vs. 0.70 cm, P < 0.01), greater bladder neck descent (22.7 mm vs. 15.1 mm, P = 0.03) and a larger hiatal area on Valsalva maneuver (21.53 vs. 14.91 cm(2), P = 0.013) compared with the control group. There were no significant differences in hiatal area at rest or on maximal voluntary contraction between the two groups.

CONCLUSION

HIFIT athletes show significant differences in several of the measured parameters for both function and anatomy of the pelvic floor. Further research into the impact of this altered function on childbirth and continence mechanisms is needed.

Physical activity and urinary incontinence among healthy, older women

OBJECTIVE

To examine the association between physical activity and risk of developing urinary incontinence (UI).

METHODS

Prospective analysis from the Nurses' Health Study of women aged 54-79 years. Physical activity was reported in 1986 and biennially afterward. To determine stable, long-term activity levels, data were averaged across all questionnaires (bottom quintile: 6.2 metabolic equivalent task hours per week or less; top quintile: more than 28.6 metabolic equivalent task hours per week). From 2000 to 2002, 2,355 cases of incident UI were identified using self-reports of leaking urine. Type of incontinence was determined from questions regarding the circumstances during which leaking occurred. We estimated adjusted odds ratios (ORs) of developing incontinence across quintiles of physical activity levels using logistic regression, controlling for numerous potential confounding factors.

RESULTS

Increasing levels of total physical activity were significantly associated with a reduced risk of UI (top versus bottom quintile of metabolic equivalent task hours per week, OR 0.81, 95% confidence interval [CI] 0.71-0.93; P for trend across quintiles <.01). Walking, which constituted approximately half of total physical activity among our participants, was related to 26% lower risk of developing UI (top versus bottom quintile, OR 0.74, 95% CI 0.63-0.88; P for trend across quintiles <.01). Specifically, total physical activity and walking were associated with a significant reduction in stress UI (physical activity: P for trend =.01; walking: P for trend =.01), but neither was related to incidence of urge UI (P for trend =.8 and P for trend =.3, respectively).

CONCLUSION

Physical activity was associated with a significant reduction in UI. Results appeared somewhat stronger for stress UI than urge UI.

LEVEL OF EVIDENCE

II.

Pelvic prolapse and urinary incontinence in nulliparous college women in relation to paratrooper training

The objective of this study was to determine whether paratrooper training is associated with pelvic support defects or urinary incontinence. Nulliparous women at The United States Military Academy were examined using the Pelvic Organ Prolapse Quantification System and completed a questionnaire regarding incontinence and exercise prior to undergoing summer military training. The exam and questionnaire were repeated following training. One hundred sixteen women completed the study (80.6%), 37 of whom had attended paratrooper training. Women who attended paratrooper training were significantly more likely to have stage II prolapse (RR=2.72, 1.37<RR<5.40; p=0.003). Additionally, women who attended paratrooper training were significantly more likely to have worsening in their pelvic support regardless of initial prolapse stage (RR=1.57, 1.12<RR<2.20; p=0.01). Twenty-four women complained of urinary incontinence; however, this was not associated with paratrooper training. The forces transmitted to the female pelvis during paratrooper training are significant and cause pelvic support defects.

Restrições causadas pela incontinência urinária à vida da mulher

O objetivo deste estudo foi identificar as restrições causadas pela incontinência urinária (IU) à vida da mulher, considerando-se o tipo de incontinência, e verificar como manejam este problema. Trata-se de uma análise secundária de dados obtidos em estudo anterior, coletados por meio de entrevista com perguntas abertas e fechadas. A amostra foi composta por 164 mulheres com queixa de IU, internadas em clínicas de ginecologia e urologia de dois hospitais-escola da cidade de Campinas, SP. Apresentavam idade entre 25 e 85 anos e 104 (64%) referiram uma ou mais restrições. Citaram alterações nas atividades sexuais (40,9%), sociais (33,5%), domésticas (18,9%) e ocupacionais (15,2%). A incontinência urinária mista e a de urgência forem as que mais afetavam a vida das mulheres. A estratégia mais utilizada para minimizar a IU foi o uso de forro e/ou absorvente higiênico. Concluiu-se que a IU tem implicações negativas no cotidiano dessas mulheres.

Lower urinary tract symptoms in middle-aged women - prevalence and attitude towards mild urinary incontinence. A community-based population study

OBJECTIVE

To investigate the prevalence and perceived bother of lower urinary tract symptoms (LUTS) in middle-aged women with and without self-reported urinary incontinence.

PATIENTS AND METHODS

In the Women's Health In the Lund Area study (WHILA 1995--2000), 32% of the participating 6,917 women, 50--59 years, reported urinary incontinence defined as involuntary urinary leakage causing a social and/or hygienic problem. Out of these, 1,500 women with (INCONT) and 1,500 without incontinence (CONT) received the Bristol Female lower urinary tract symptoms (LUTS) questionnaire in January 2001.

RESULTS

A total of 2,682 (89%) women were included. Most common LUTS in the INCONT and CONT groups, respectively, were any urinary leakage (93.8% vs. 53.3%, P<0.001), urgency (86.2% vs. 62.5%, P<0.001), stress incontinence (85.1% vs. 41%, P<0.001), and frequency (86.9% vs. 35.6%, P<0.001). The two groups differed significantly in the degree of reported bother by infrequently occurring stress and urge incontinence. Urinary leakage more than once a week was reported as bothersome by 97.5%. The prevalence of self-reported urinary incontinence increased from 32% to estimated 66% if the demand for social and/or hygienic bother was omitted from the definition. Conclusion. The prevalence of self-reported urinary incontinence increased from 32% to estimated 66%, if the demand for social and/or hygienic bother was omitted from the definition. LUTS other than incontinence are common in middle-aged women, with a significantly higher prevalence in women with self-reported incontinence than in continent women. The attitude towards stress- and urge incontinence varied widely when the symptoms occurred infrequently. Urinary leakage more than once a week was considered bothersome by 97.5%.

Pelvic organ prolapse and urinary incontinence in nulliparous women at the United States Military Academy

The objective of this study was to evaluate both baseline pelvic support and incontinence in relation to physical activity in nulliparous college women. Participants were examined using the pelvic organ prolapse and quantification system (POP-Q) and completed a questionnaire. Women with stage 0 prolapse and any other stage were compared. Potential risk factors and levels of physcial activity were analyzed using the chi-square test. We evaluated 144 women. Fifty percent had stage 0 support and 50% had stage I or II. Nineteen percent of participants reported incontinence. No risk factors for prolapse were identified, however running was associated with incontinence. Forty-six percent of physically active nulliparous college students had stage I pelvic support without identifiable risk factors. Stage I and II prolapse represent normal support.
