Abstract

Objective: To investigate the risk factors for postpartum urinary incontinence (UI) and its characteristics.

Method: This was a case-control study with 344 puerperal women (77 cases and 267 controls) with up to 90 days postpartum. In a single session, participants were given a questionnaire with sociodemographic and clinical data and two others that assessed urine leakage, leakage situations, and type of UI.

Results: Stress UI was present in 45.5% of the women, incidents of urine leakage several times a day in 44.2%, of which 71.4% were in small amounts and 57.1% when coughing or sneezing. In 70.1% of cases, UI began during pregnancy and remained through the postpartum period. After running a binary logistic regression model, the following factors remained in the final model: UI during pregnancy (OR 12.82, CI 95% 6.94 - 23.81, p<0.0001), multiparity (OR 2.26, CI 95% 1.22 - 4.19, p=0.009), gestational age at birth greater or equal to 37 weeks (OR 2.52, CI 95% 1.16 - 5.46, p=0.02) and constipation (OR 1.94, CI 95% 1.05 - 5.46, p=0.035).

Conclusion: Most often, UI first appeared during pregnancy and remained through the postpartum period. Urinary incontinence during pregnancy, multiparity, gestational age at birth greater or equal to 37 weeks, and constipation were presented as risk factors. In the studied group, stress UI was more frequent.

Objetivo: Investigar os fatores de risco para a incontinência urinária (IU) no puerpério e as suas características.

Método: Trata-se de estudo caso-controle com 344 puérperas (77 casos e 267 controles), com até 90 dias pós-parto. Foi aplicado, em um único momento, um questionário para os dados sociodemográficos e clínicos, e dois outros para avaliar a perda urinária, situações de perda e o tipo de IU.

Resultados: Apresentaram IU de esforço 45,5%, perda urinária diversas vezes ao dia 44,2%, sendo 71,4% em pequena quantidade e 57,1% ao tossir ou espirrar. Em 70,1% dos casos a IU iniciou-se na gestação e permaneceu no puerpério. Ao ajustar-se um modelo de regressão logística binária, apenas IU na gestação (OR 12,82, IC 95% 6,94 - 23,81, p<0,0001), multiparidade (OR 2,26, IC 95% 1,22 - 4,19, p=0,009), idade gestacional no parto maior ou igual a 37 semanas (OR 2,52, IC 95% 1,16 - 5,46, p=0,02) e constipação (OR 1,94, IC 95% 1,05 - 5,46, p=0,035) permaneceram no modelo final.

Conclusão: A IU iniciou-se frequentemente na gestação e permaneceu no puerpério. A presença de IU na gestação, multiparidade, idade gestacional no parto maior ou igual a 37 semanas e constipação foram fatores de risco. No grupo estudado a IU de esforço foi a mais frequente.
