UK Biobank Dietary Inflammation and Crohn's Disease Risk Study

207,582 participants from the UK Biobank were analyzed over a mean follow-up of 12.65 years, with 455 incident Crohn's disease cases documented. The study by Na Zhao examines the association between energy-adjusted Dietary Inflammatory Index (E-DII) scores and disease risk. The data was last updated on 2026-04-29.

Use Cases

• Analyze the association between pro-inflammatory diet scores and Crohn's disease risk based on E-DII quartiles.
• Validate Cox regression models for dietary risk factors based on the described multivariable analysis.
• Perform sensitivity and subgroup analyses on dietary inflammation data based on the study's methodology.

Strengths

• 207,582 participants provides a substantial cohort size.
• 12.65 years of mean follow-up offers longitudinal perspective.
• 455 incident cases allow for statistical analysis of a rare outcome.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is a 178.9 KB PDF supplementary file, indicating limited scope and likely summary data rather than raw records.
