PAF: population attributable fraction; CI: confidence interval; BMI: body mass index; CRF: cardiorespiratory fitness; CVD: cardiovascular disease.
PAF value at 5th, 10th, and 15th year was denoted by PAF5, PAF10, and PAF15, respectively.
The definition of smoking, BMI, diet, CRF is the same as in Table 2.
Adjusted for age, gender, hypertension, diabetes, hypercholesterolemia, and family history of CVD.
