Prevalence and factors associated with urinary incontinence in climacteric / Prevalência e fatores associados à incontinência urinária no climatério

SUMMARY Objective: To estimate the prevalence and identify associated factors to urinary incontinence (UI) in climacteric women. Method: In a cross-sectional study with a stratified random sample, 1,200 women aged between 35 and 72 years were studied, enrolled in the Family Health Strategy in the city of Pindamonhangaba, São Paulo. Urinary incontinence was investigated using the International Consultation of Incontinence Questionnaire - Short Form, while associated factors were assessed based on a self-reported questionnaire with socio-demographic, obstetric and gynecological history, morbidities and drug use. The prevalence of urinary incontinence was estimated with a 95% confidence interval (95CI) and the associated factors were identified through multiple logistic regression model performed using Stata software, version 11.0. Results: Women had a mean age of 51.9 years, most were in menopause (59.4%), married (87.5%), Catholic (48.9%), and declared themselves black or brown (47.2%). The mean age of menopause of women with UI was 47.3 years. The prevalence of UI was 20.4% (95CI: 17.8-23.1%). The factors associated with UI were urinary loss during pregnancy (p=0.000) and after delivery (p=0.000), genital prolapse (p=0.000), stress (p=0.001), depression (p=0.002), and obesity (p=0.006). Conclusion: The prevalence of UI was lower but similar to that found in most similar studies. Factors associated with the genesis of UI were urinary loss during pregnancy and after delivery, genital prolapse and obesity.

RESUMO Objetivo: estimar a prevalência e identificar os possíveis fatores associados à incontinência urinária (IU) em mulheres no climatério. Método: em estudo analítico transversal com amostra aleatória estratificada, foram estudadas 1.200 mulheres, entre 35 e 72 anos, cadastradas na Estratégia de Saúde da Família do município de Pindamonhangaba, SP. A IU foi investigada por meio do International Consultation of Incontinence Questionnaire – Short Form e os fatores associados, por meio de questionário autorreferido, contendo informações sociodemográficas, história ginecológica e obstétrica, morbidades e uso de medicamentos. Estimou-se a prevalência da incontinência urinária com intervalo de confiança de 95% (IC95%), e os fatores associados foram identificados por meio de um modelo de regressão logística múltipla realizada no Programa Stata, versão 11.0. Resultados: as mulheres apresentavam média etária de 51,9 anos, estavam na menopausa (59,4%), eram casadas (87,5%), católicas (48,9%) e declararam-se negras ou pardas (47,2%). A média de idade da menopausa das mulheres com IU foi de 47,3 anos. A prevalência de IU foi de 20,4% (IC95%: 17,8-23,1). Os fatores associados à IU foram perda urinária na gestação (p=0,000) e no pós-parto (p=0,000), prolapso genital (p=0,000), estresse (p=0,001), depressão (p=0,002) e obesidade (p=0,006). Conclusão: a prevalência de IU foi inferior, mas semelhante à encontrada na maioria dos estudos análogos. Os fatores associados à gênese da IU foram perda urinária na gestação e no pós-parto, prolapso genital e obesidade.
