Results: One thousand seventy nine volunteers with completed data were included. One hundred fifty three (14.2%) were
known HT, 143 (19.5%) out of 735 and 62 (32.5%) out of 191volunteers, with no history of HT did not know that their BP
reached hypertensive level. Therefore, 205 (22.1%) from 926 volunteers were hypertensive with 89 (26.6%) from 335 men,
116 (19.6%) from 591 women (p = 0.0145) and 32 (3.5%) with isolated systolic hypertension. HT increased significantly in
age of 60-69 y, more than 50-59 y and 40-49 y, BMI over 25 (p = 0.0002) and drinking alcohol (p = 0.0384). However, it did
not increase with smoking (p = 0.2139) and eating salty foods (p = 0.6568). The group which ate sour taste had borderline
significance for negative risk of hypertension (p = 0.0489).
