Abstract

Background: The aim of this study is to explore the association between the systemic immune-inflammatory index (SII) and stress urinary incontinence (SUI). Methods: We used information obtained from the National Health and Nutrition Examination Survey (NHANES) that was conducted between 2007 and 2016. The weighted multivariate logistic regression model was used in order to evaluate the relationship that exists between the SII index and the SUI measurement. In addition, a technique from the field of smooth curve fitting was used to investigate the linear connection that exists between these variables. In order to determine whether or not the SII index and SUI relationship remained stable across a variety of demographic strata, subgroup analyses were carried out. Results: The research had a grand total of 20,849 individuals. After full adjustment for confounders, each 1-unit increase in log₁₀(SII) was associated with a 29.7% increase in the odds of SUI (OR=1.297, 95%CI 1.028–1.636, P = 0.032). Categorizing the SII index into quartiles revealed that even in the highest SII quartile, there remained a significant positive association with SUI when compared to the lowest quartile (OR =1.177, 95%CI 1.013–1.368, P = 0.038). Furthermore, an augmented correlation between alcohol consumption and SUI was detected among drinkers compared to non-drinkers (P
