  • 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.

  • Model 1: age, cohort, educational level, OPA and SpPA.

  • Model 2: model 1 plus body mass index, total cholesterol, HDL cholesterol, systolic BP, current smoking, diabetes and alcohol intake.

  • *Wald heterogeneity χ2 test (2 df).

  • †Wald trend χ2 test (1 df).

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