Comparison of Three Anonymization Tools for a Health Fitness Study

This is data generated by three different anonymization tools, ARX, SDV, and SynDiffix for a data anonymization study. The original data is available upon request as described in the paper. The original study using the original is:

Jurak, G. et al. Associations of mode and distance of commuting to school with cardiorespiratory fitness in slovenian schoolchildren: a nationwide cross-sectional study. BMC Public Heal. 21, 1–10 (2021).

The data has 713 records, one per individual, and contains the following columns:
• VO2max: Float. Maximum oxygen consumption during exercise, measured in milliliters of oxygen per kilogram of body weight per minute (ml/kg/min). VO2max is a key indicator of cardiorespiratory fitness and
aerobic endurance. Higher values indicate better cardiovascular fitness.
• CommToSch: String. Mode of commuting to school. Contains the categorical values “walk”, “wheels”, “car”
and “public”.
• CommHome: String. Mode of commuting from school to home. Contains the categorical values “walk”,
“wheels”, “car” and “public”. This may differ from CommToSch if students use different transportation methods for their return journey.
• gender: String. Gender of the participant. Contains categories “male” and “female”.
• age: Float. Age of the participant in years. The float type suggests precision beyond whole years (e.g., 12.5
years).
• MVPAsqrt: Float. Square root transformed value of Moderate to Vigorous Physical Activity. The square root
transformation is commonly applied to normalize skewed physical activity data. This represents the amount
of meaningful physical activity performed, transformed for statistical analysis.
• DistFromHome: Integer. Distance from participant’s home to their school, measured in meters.
• DistFromSchool: Integer. Distance from school to participants homes, measured in meters.
