aOptimal risk factors are defined as SBP less than 120 mmHg, DBP less than 80 mmHg, non-HDL-C less than 3.11 mmol/l, BMI less than 24 kg/m2, HDL-C at least 1.04 mmol/l, nonsmoker, and no diabetic. Not optimal risk factors are defined as SBP from 120 to 139 mmHg, DBP from 80 to 89 mmHg, non-HDL-C from 3.11 to 4.14 mmol/l, nonsmoker, and no diabetic. Elevated risk factors are defined as SBP from 140 to 159 mmHg, DBP from 90 to 99 mmHg, non-HDL-C from 4.14 to 5.18 mmol/l, BMI from 24 to 28 kg/m2, smoker, and diabetic. High risk factors are defined SBP at least 160 mmHg, DBP at least 100 mmHg, non-HDL-C at least 5.18 mmol/l, BMI at least 28 kg/m2, and HDL-C less than 1.04 mmol/l.
