Prevalence and risk factors of urinary incontinence in women who visit the doctor with low back pain: Multicentre study

Objectives: Estimating prevalence and risk factors of urinary incontinence (UI) in women with low back pain (LBP) and describing their social and demographic and clinical features. Design: Cross-sectional study. Setting: Two primary care health centres in south of Cordoba and a private center in Madrid. Participants: 364 women of 20-65 years of age (of 466 who were contacted, 33 of them were excluded and 69 refused to participate) who had low back pain located between the twelfth rib and the gluteal fold. Interventions: Medical questionnaire. Main measurements: Questionnaires (Oswestry Disability Index and UI questionnaires [International Consultation on Incontinence Questionnaire SF and Incontinence Impact Questionnaire-7]), functional test (ASLR Test) and comorbidity of interest for the UI. Descriptive and multivariate statistical analysis. Results: UI was detected in 155 women (43%, 95% CI: 37%-48%), the majority of stress (83%) and a minimal impact (60%). Front of the continents, incontinent women showed significant differences in age, body mass index, marital status, level of education, coexistence, consumption of drugs/day, number of vaginal and total deliveries, abdominal and pelvic surgery, asthma, constipation, hypertension, diabetes, percentage of disability and functional ASLR test. In multivariate analysis, the variables influencing the probability of being incontinent were asthma, hypertension, constipation, total parity, BMI and the percentage of disability. Conclusions: Prevalence of UI is higher than in women without low back pain. Asthma, constipation and parity are the most influential factors in the occurrence of UI. (C) 2013 Elsevier Espana, S.L.
