Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

CDAI Q1 (Lowest Quartile)

None (Observational)

Intervention Type OTHER

This is an observational study with no active intervention implemented. Its primary aim is to analyze the relationship between the Composite Dietary Antioxidant Index (CDAI) and overweight/obesity, as well as the associated metabolic abnormalities, using the dataset-with no experimental manipulation involved.

CDAI Q2 (Second Quartile)

None (Observational)

Intervention Type OTHER

This is an observational study with no active intervention implemented. Its primary aim is to analyze the relationship between the Composite Dietary Antioxidant Index (CDAI) and overweight/obesity, as well as the associated metabolic abnormalities, using the dataset-with no experimental manipulation involved.

CDAI Q3 (Third Quartile)

None (Observational)

Intervention Type OTHER

This is an observational study with no active intervention implemented. Its primary aim is to analyze the relationship between the Composite Dietary Antioxidant Index (CDAI) and overweight/obesity, as well as the associated metabolic abnormalities, using the dataset-with no experimental manipulation involved.

CDAI Q4 (Highest Quartile)

None (Observational)

Intervention Type OTHER

This is an observational study with no active intervention implemented. Its primary aim is to analyze the relationship between the Composite Dietary Antioxidant Index (CDAI) and overweight/obesity, as well as the associated metabolic abnormalities, using the dataset-with no experimental manipulation involved.
