Hypertension awareness, treatment and control rates for an Asian population: Results from a national survey in Korea
Key result
A national blood pressure survey in Korea revealed low rates of hypertension awareness (25-40%), treatment (16-27%), and control (5-14%) depending on the blood pressure threshold used.

Implication
Highlights low hypertension awareness in Korea; leaves open whether ethnicity-specific strategies improve detection in similar populations.
Key Points
- To evaluate the national rates of hypertension awareness, treatment, and blood pressure control in Korea.
- Conducted a nationwide survey in 1990 using cluster sampling across 190 of 146,944 districts in Korea among adults aged > 30 years (N=21,242 completed blood pressure measurements and questionnaires out of 25,567 eligible).
- Calculated blood pressure from the mean of two measurements using a standard mercury manometer, assessing treatment (dietary, traditional, or medical) and two diagnostic thresholds: ≥160/95 mm Hg or treated (n=2,628) and ≥140/90 mm Hg or treated (n=4,219).
- Using the ≥160/95 mm Hg threshold (n=2,628), awareness was 40% (1,057/2,628), treatment was 27% (696/2,628), and blood pressure control was 14% (367/2,628).
- Using the ≥140/90 mm Hg threshold (n=4,219), awareness dropped to 25% (1,069/4,219), treatment dropped to 16% (696/4,219), and blood pressure control reached only 5% (221/4,219).

Hypertension awareness, treatment, and control rates
A 1990 national survey in Korea revealed very low rates of hypertension awareness, treatment, and control, highlighting the need for improved detection and management strategies.
