INTRODUCTION: The aim of this review was to assess the prevalence of gastrointestinal (GI) and lower urinary tract symptoms (LUTS) in sportswomen having high intensity training and to determine whether the type of sport might also affect LUTS and GI symptoms.
EVIDENCE ACQUISITION: A systematic review of the literature was performed by searching PubMed, CINAHL, Cochrane Library and Web of Science up to November 2018. The search strategy included several keywords concerning pelvic floor disorders, urinary dysfunction, bowel dysfunction, sportswomen, and elite sports. Inclusion criteria were studies of women who performed any kind of sport with a prevalence of LUTS and/or bowel symptoms without any restriction for age, sport modality or frequency of training. Outcomes were prevalence of LUTS and GI symptoms and meta- analyses and moderator analyses to identify risk factors for the occurrence of these symptoms in female athletes.
EVIDENCE SYNTHESIS: The search screened 1263 records, 31 of which met the methodological criteria for qualitative analysis and 5 for meta-analysis. Sportswomen during daily activity showed a 3-fold higher risk to develop urinary incontinence (UI) than controls (OR 3.13; CI 95% 2.39-4.00). No differences were found stratifying data for UI types. Cumulative prevalence rates were: 58.7% of all kinds of UI (daily life together with sport time), 32.8% at rest (during daily life out of sport time), 36.3% during sport time; 23% of stress urinary incontinence (SUI) during sport time versus 38.6% at rest; 11% of urge urinary incontinence (UUI) during sport time versus 17.8% at rest; 11.9% of mixed urinary incontinence (MUI) during sport time versus 20.7% at rest. Prevalence rates of GI symptoms before sport time were 57.6%, during sport competition 35.2% and 58.2% after competition.
CONCLUSIONS: All the analysed studies showed bias. This meta-analysis indicated that competitive sport activities represent a risk factor for urinary incontinence and gastrointestinal disorders. To prevent urinary leakage athletes should be instructed to strengthen the pelvic floor muscles.
