Recent studies have demonstrated that the triglyceride\u2013glucose index (TyG) and the Chinese visceral adiposity index (CVAI), which reflect insulin resistance and visceral adiposity, are linked to elevated odds of diabetes. However, the combined use of TyG and CVAI for identifying diabetes remains underexplored. This study aimed to investigate the relationship among TyG, CVAI, and their joint association with prevalent diabetes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      This cross-sectional study included 11,495 participants from the 2023 Shenzhen Chronic Diseases and Risk Factors Surveillance Survey. A structured questionnaire survey, physical examinations, and fasting blood sample collection were conducted for all participants. Logistic regression models were used to calculate odds ratios (ORs) with 95% confidence intervals (CIs). Restricted cubic spline (RCS) was employed to assess potential nonlinear relationships (all\n                      <jats:italic>P<\/jats:italic>\n                      for nonlinear &amp;lt;0.001).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The study identified 831 participants with diabetes. After adjusting for confounders, TyG (OR: 4.48, 95% CI: 3.66\u20135.52) and CVAI (OR: 6.02, 95% CI: 3.69\u201310.05) were independently associated with the odds of diabetes.

The combination of TyG and CVAI demonstrated the highest discriminative ability (AUC: 0.785, 95% CI: 0.771\u20130.799), outperforming TyG alone (AUC: 0.769, 95% CI: 0.754\u20130.785) and CVAI alone (AUC: 0.744, 95% CI: 0.729\u20130.759).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Elevated TyG and CVAI levels, as well as their combined use, were significantly associated with increased odds of diabetes.
