This study compared two populations in the Brazilian Amazon, one comprising urban women and the other indigenous origin women from a riparian population, to assess the prevalence of and risk factors associated with stress urinary incontinence (SUI).
Following sample calculation, 120 indigenous and 260 urban women underwent evaluations including medical history, UI-oriented physical examination, pelvic organ prolapse, and functional assessment of the pelvic floor. Women with complaints of SUI underwent a urodynamic study and completed a quality of life questionnaire (King's Health Questionnaire). Univariate ORs were calculated, and multiple logistic regression models were then built using the stepwise backward method.
The prevalence of SUI was similar in both groups (25.8% in indigenous origin women and 20.4% in the urban group (P > 0.05). The parity and number of spontaneous deliveries and home births were higher in the indigenous origin group. Multivariate analysis showed a decreased prevalence of SUI in patients with modified Oxford Scale scores ≥ 3. Women with homebirths had a 3.45-fold higher likelihood of having SUI than women with hospital deliveries (OR 3.45 -CI 1.78-6.70). Quality of life was worse in the domains of SUI impact, hindering daily and physical activities as well as jeopardizing personal and emotional relationships in urban women.
No significant difference in SUI was observed between the groups, despite significantly higher risk factors for SUI in the indigenous origin group.
