Mean (SE) for continuous variable and weighted % were reported for categorical variables.
Crude sample size was reported for each blood pressure levels.
aWithin category proportion (column %) of female were reported after age and gender adjustment; however, between category proportion (row %) are 28%, 1.92%, 10.7%, 3.62% and 6.14% for classification of hypertension; normal blood pressure, elevated blood pressure, stage 1 hypertension, stage 2 hypertension and those on medication, respectively.
b10-year predicted risk was calculated based on ACC/AHA pooled cohort risk equation16.
cAccording to the JNC 7 guideline, categories are defined as (Normal, pre-hypertension, prehypertension and stage 1 hypertension, respectively)
SBP: Systolic blood pressure; DBP: Diastolic blood pressure; TC: Total cholesterol; HDL-C: High density lipoprotein cholesterol; FPG: Fasting plasma glucose; eGFR: estimated glomerular filtration rate; CKD: chronic kidney dieses; CVD: Cardiovascular disease.
