Summary
In hypertension, lifestyle modification has been proven to be effective in reducing blood
pressure while decreasing the risk of cardiovascular disease. The dietary approaches to stop
hypertension(DASH) diet, sodium restriction and exercise has been shown to reduce systolic
blood pressure by 8-14mmHg, 2-8mmHg and 4-9mmHg, respectively. The DASH-sodium diet has been
shown to have additional systolic blood pressure lowering effect of 7.2mmHg, which is equal
to adding one antihypertensive drug. However, as the dietary pattern is different in the
Korean population, the investigators cannot implement the data from Western countries
directly to the Korean population. For example, the consumption of dairy products is much
smaller in the Korean population when compared to the western population. Therefore, the
effectiveness of DASH-sodium diet and exercise on blood pressure lowering in the Korean
population is not well defined. In this study, the investigators sought to determine the
effectiveness of the DASH-salt diet and DASH-salt diet plus exercise on brachial blood
pressure lowering. The study will be performed on untreated prehypertension patients and
uncontrolled hypertensive patients undergoing anti hypertensive treatment with blood pressure
measured between 140-159mmHg/90-99mmHg at the time of enrollment.
