Evaluating weight-adjusted waist index as a risk factor for chronic obstructive pulmonary disease: A cross-sectional analysis of NHANES data

This study found a significant and nonlinear positive association between WWI, a marker of central obesity, and COPD risk. Weight-adjusted waist index may be an independent predictor of COPD risk and provide insight into the contribution of obesity to the disease. Given the increasing burden of COPD, integrating WWI into clinical practice could enhance preventive efforts and personalized interventions.
