Stage 2 hypertension incidence. | All subjects (men): 25.3% (10.4 to 35.8)* | Activity of daily living: stair-climbing and block-walking. + Vigorous-intensity sports. |

2002, Japan. |
Stage 1 hypertension incidence. | All subjects (men): 13% (3 to 22) | Exercise subset: regular exercise ≥40 min/week, 20 min/day, 2 days/week (intensity not specified). |

Moderate intensity (3–6 METs), vigorous intensity (8 METs). |
*Substitution method was used to estimate 95% CI for the PAF.
†EE calculated and rounded37: EE=METs × (t/week) x BM (expressed in kcal/week), where EE is the energy expenditure expressed in kcal/week, t is the exercise duration expressed in hours, and BM is the body mass expressed in kg.
EE, energy expenditure; PA, physical activity; PAF, population attributable fraction.
