Association Between Physical Activity and Inflammatory Bowel Disease in UK Biobank Cohort

UK Biobank data from 293,578 participants was used in a prospective cohort study to evaluate the longitudinal relationship between physical activity intensity and the risk of developing Crohn's disease and ulcerative colitis. The analysis employed multivariable Cox proportional hazards regression models and restricted cubic spline curves. The dataset was authored by Yitian Wei and last updated in May 2026.

Use Cases

• Assessing the protective effect of total physical activity on Crohn's disease risk based on the study's findings.
• Investigating the nuanced, intensity-dependent relationship between physical activity and ulcerative colitis risk described in the results.
• Validating the association between exceeding standard health recommendations for activity and reduced UC risk within specific subpopulations.
• Examining the paradoxical link between excessive light physical activity and increased UC risk mentioned in the study.

Strengths

• Large-scale prospective cohort of 293,578 participants from the UK Biobank.
• Incident IBD cases were identified through linked hospital admission and death registry records.
• Analysis includes multivariable Cox models and restricted cubic spline curves for non-linear associations.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data relies on self-reported physical activity, which may introduce measurement bias.
