This study aims to explore the association between SII and SUI in women.Methods: Adult participants from the 2007– 2018 NHANES were included. Weighted multivariate logistic regression and subgroup analysis were conducted to determine the relationship between SII and SUI. The non-linear relationship between SII and SUI risk was evaluated using restricted cubic splines (RCS), and the inflection point was determined by two-piecewise logistic regression.Results: A total of 10,776 women were included, of whom 4407 (40.9%) had SUI. After adjusting for all confounders, a significant positive association between SII and SUI risk was observed (OR: 1.09; 95% CI: 1.01– 1.19, P = 0.021); Moreover, when compared with the women in the lowest SII tertile, those in the highest SII tertile had a 15% increased risk of SUI (OR: 1.15; 95% CI: 1.00– 1.31, P = 0.049). Subgroup analysis showed that there were consistent relationships between SII and SUI across most subgroups. A non-linear relationship between log2SII and SUI was observed by RCS analysis. Furthermore, the two-piecewise logistic regression demonstrated that the odds of being SUI increased with the SII level, and this rising trend gradually slowed down after passing the inflection point of 8.64.Conclusion: Our findings suggest an association between elevated SII levels and an increased likelihood of SUI in women. Further well-designed prospective studies are needed to substantiate our results.Keywords: systemic immune-inflammation index, stress urinary incontinence, population-based study, NHANES, cross-sectional study
