Dietary Inflammation and COPD Risk Analysis from UK Biobank

A research dataset of 167,440 UK Biobank participants analyzed for associations between dietary inflammatory indices and chronic obstructive pulmonary disease risk. The study, authored by Aimin Wang and last updated in May 2026, followed participants for a median of 13.4 years, during which 4,041 COPD cases occurred. It includes hazard ratios and mediation analyses involving inflammatory biomarkers like C-reactive protein.

Use Cases

• Modeling COPD risk based on dietary inflammatory scores.
• Conducting mediation analysis to understand the role of biomarkers like CRP and SII.
• Performing subgroup analyses to explore population heterogeneity in diet-disease associations.
• Validating the Dietary Inflammatory Index (DII) and Energy-adjusted DII (E-DII) in a large cohort.

Strengths

• Large prospective cohort of 167,440 participants from the UK Biobank.
• Longitudinal design with a median follow-up of 13.4 years and 4,041 observed COPD cases.
• Includes analysis of two dietary indices (DII and E-DII) and multiple inflammatory biomarkers.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic and demographic bias inherent to the UK Biobank cohort.
