Data are mean (SD) or %.
Calculated as the weight in kilograms divided by the square of the height in meters.
Defined as alcohol drinks >14 and >7 per week for men and women, respectively.
Total physical activity levels from other leisure-time activities except running.
Defined as systolic or diastolic blood pressure ≥140/90 mmHg or history of physician diagnosis.
Defined as fasting glucose ≥126 mg/dl, current therapy with insulin, or history of physician diagnosis.
Defined as total cholesterol ≥240 mg/dl or history of physician diagnosis.
Defined as abnormal resting or exercise electrocardiogram including rhythm and conduction disturbances and ischemic ST-T wave abnormalities.
Estimated from the final treadmill speed and grade during the maximal exercise test in a subsample of 50,995 participants. MET denotes metabolic equivalent.
