  • Men aged 25–64 years, free of CVD and currently employed at baseline (n=3574). Rates (x1000 person-years) are age adjusted and estimated at the sample mean age.

  • Adjusted for age, cohort type (population-based vs factory-based), educational level, body mass index, total cholesterol, HDL cholesterol, systolic BP, current smoking, diabetes and alcohol intake.

  • *Waldχ 2 test (5 df).

  • †Waldχ 2 test for interaction (2 df).

  • BP, blood pressure; CHD, coronary heart disease; CVD, cardiovascular disease; HDL, high-density lipoprotein; OPA, occupational physical activity; SpPA, sport physical activity.
