Summary

This cross-sectional study draws on data from the National Health and Nutrition Examination Survey (NHANES) database. The primary objective is to investigate the associations between the Composite Dietary Antioxidant Index (CDAI) and overweight/obesity, as well as the related metabolic abnormalities, among the U.S. general population. By analyzing this large-scale, nationally representative dataset, the investigators seek to generate evidence that can inform public health policies and clinical practice-ultimately contributing to a deeper understanding of population-level health challenges and the development of targeted strategies to address them.
