  • Adjusted for age, education, occupation, family history of CVD, medication for hypertension, smoking, body mass index, sedentary behaviour and alcohol intake.

  • *p<0.05 for difference in ABP changes over 5 years (years 5 –1 ABP), compared with reference category (never-exposed workers).

  • ABP, ambulatory blood pressure; CVD, cardiovascular diseases; ERI, effort–reward imbalance.
