UK Biobank Physical Activity and Mortality Supplementary Data

Supplementary files for a research article analyzing the association between physical activity patterns and mortality risk. The study used accelerometer data from 94,541 UK Biobank participants, with a median follow-up of 6.9 years and 2,649 recorded deaths. The files, authored by Alex V. Rowlands and last updated in April 2026, support findings on how activity intensity and bout duration modify mortality risk.

Use Cases

• Replicate mortality risk analysis based on continuous versus sporadic physical activity bouts.
• Model the moderating effect of intensity (moderate vs. vigorous) on mortality associations.
• Validate hazard ratios for different durations of the most active minutes of the day.
• Analyze accelerometry-derived metrics like MXCONT, MX, and MXRATIO in relation to health outcomes.

Strengths

• Data is linked to a peer-reviewed study with specific results, including hazard ratios and confidence intervals.
• Includes a large cohort of 94,541 participants with accelerometer-assessed physical activity.
• Follow-up period of median 6.9 years with 2,649 mortality events provides substantial longitudinal data.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count for the supplementary data files is unknown, which may limit suitability assessment.
• The dataset is small (5.8 MB), which may limit the scope of the included data.
