Abbreviations: OPA, occupational physical activity; PCa, prostate cancer; RPA, recreational physical activity.

  • aAdjustment was made for the following covariates (values at baseline): birth-year, age, height, body mass index, type 2 diabetes, smoking, family history of prostate disease, education, and regular health check-ups.

    Number of individuals in multiadjusted analysis was 3% to 4% lower than in the age-adjusted analysis (due to missing values for covariates).

    Data on OPA and/or RPA were missing or incomplete for 855 men, leaving 8,221 men in the analytic cohort.
