  1. MI, myocardial infarction; IR, incidence rate, HR, hazard ratio; CI confidence interval.
  2. *Health Metric Score is defined as the number of ideal health levels for six cardiovascular disease risk factors.
  3. 1) Body Mass Index < 25 kg/m2.
  4. 2) Total cholesterol < 5.18 mmol/l (<200 mg/dl).
  5. 3) Systolic blood pressure < 120 mmHg and diastolic blood pressure < 80 mmHg.
  6. 4) Non-smokers.
  7. 5) Moderate physical activity ≥ 3 hours per week or vigorous physical activity ≥ 1 hours per week.
  8. 6) Non – Diabetes.
  9. †Percent of participants.
  10. ‡Age adjusted incidence rate per 100,000 person-years from poisson regression.
  11. §Age adjusted Cox proportional hazard regression models with updated values of health metrics score during follow-up using participants with score ≤ 1 as the reference level.
  12. ||HR per unit increase in health metric score.
  13. The Tromsø Study 1994–2008.
