  • Model 1. Unadjusted.

  • Model 2. Adjusted for childhood factors (birth year, region, parental SEI and household crowding).

  • Model 3. Adjusted for 2+ characteristics in adolescence (cognitive function, diastolic and systolic blood pressure and CVD diagnosis at conscription).

  • Model 4. Adjusted for 2+3+ physical fitness and body mass index in adolescence.

  • CVD, cardiovascular disease; SEI, socioeconomic index.
