Chronic obstructive pulmonary disease (COPD) is a major global health burden. The weight-adjusted waist index (WWI), novel adiposity metric, may improve COPD risk prediction, but its association remains underexplored. Using the National Health and Nutrition Examination Survey (NHANES) 2013-2018 data (n=15,278), we assessed WWI-COPD relationship via multivariable logistic regression, ROC analysis, subgroup evaluations. Higher WWI tertiles correlated with elevated incidence. After full adjustment, each unit increase linked to 70% higher (OR=1.70, 95% CI: 1.48-1.95). Participants in highest quartile of faced 290% increased compared lowest (OR=3.90, 2.60-5.86). (AUC=0.707) outperformed BMI (AUC=0.525) circumference (AUC=0.609) prediction. A nonlinear threshold effect emerged at WWI=12.54. Subgroup analyses confirmed robustness across demographics. simple, cost-effective tool for early detection, outperforming circumference, especially resource-limited settings, enabling timely intervention reducing
