The presence or absence of obesity was identified using the BRI, and Pso was assessed using the Pso questionnaire. The association of BRI with Pso was explored by weighted multivariate logistic regression analyses and restricted cubic spline (RCS) analyses, and the threshold effect was further examined using two\u2010stage linear regression models. Mediation analyses assessed SII\u2019s role in the BRI\u2010Pso association. The Pso group included 445 out of 14,669 participants. Logistic regression analyses indicated a positive association between BRI and Pso after adjusting for potential confounders. RCS analyses showed a nonlinear relation between BRI and Pso (\n                      <jats:italic>P<\/jats:italic>\n                      <jats:sub>nonlinear<\/jats:sub>\n                      \u2009=\u20090.018), with a point of inflection at 5.103 (odds ratio [OR]\u2009=\u20091.09, 95% CI: 1.04, 1.14). BRI and Pso were positively correlated on the left side of the point of inflection (OR\u2009=\u20091.25, 95% CI: 1.09, 1.45), whereas such an association was not detected on the right side (OR\u2009=\u20091.04, 95% CI: 0.97, 1.11).
