Korean Adult PFAS Serum Levels Linked to Physical Exercise, 2018–2020

The Korean National Environmental Health Survey Cycle 4 (2018–2020) provides data on 2,993 Korean adults. It links serum concentrations of five individual per- and polyfluoroalkyl substances (PFAS) and their sums to physical exercise metrics. The analysis was conducted by Kiook Baek and published on figshare in 2026.

Use Cases

• Modeling the inverted U-shaped association between exercise volume and serum PFAS levels based on the described regression analysis.
• Investigating sex-specific patterns in pollutant mobilization and elimination based on the described findings for men and women.
• Assessing the mediating role of performance outdoor apparel use on PFAS exposure based on the described adjustment in the analysis.

Strengths

• Data from 2,993 adults provides a substantial sample size for analysis.
• Survey-weighted linear regressions were used, suggesting a methodologically sound approach.
• Exercise was operationalized in multiple ways (binary status, frequency, volume), allowing for nuanced analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count for the underlying dataset is unknown, which may limit suitability assessment.
• The 485.9 KB size indicates a very limited data scope, likely containing summary or analysis results rather than raw individual-level data.
