MI, myocardial infarction; HR, hazard ratio; CI confidence interval.
*Age adjusted Cox proportional hazard regression models. The health metrics were updated for those who attended the follow-up examinations in 2001 or 2007–08 and did not experience an event prior to the follow-up examination.
†Systolic blood pressure < 120 mmHg and diastolic blood pressure < 80 mmHg.
‡Moderate physical activity ≥ 3 hours per week or vigorous physical activity ≥ 1 hour per week.
