1 The tertiles of the sample distribution of physical activity were 1.41, 1.58 and 3.46 MET*hour/day among women and 1.38, 1.61 and 3.26 MET*hour/day among men;

2 Optimal blood pressure was defined as systolic <120 mmHg and diastolic <80 mmHg, normal blood pressure as systolic 120–129 mmHg or diastolic 80–84 mmHg and high normal blood pressure as systolic 130–139 mmHg or diastolic 85–89 mmHg. If systolic and diastolic blood pressure readings belonged to different categories, the highest was considered.
