Purpose: This study was conducted to evaluate the effects of aerobic exercise on health status with essential hypertension. Method: A non-equivalent control group design was used. For the experimental group, aerobic exercise was given by researcher at one health center in Daegu. Test for hypothesis was done by $X^2$-test t-test, paired t-test, and unpaired t-test. Result: There were significant differences in systolic, diastolic, and MAP between two groups. There were significant differences in body weight, BMI, and body composition between two groups. Hypothesis 3 was partially supported that the score of health status and physical function of experimental group were significantly higher than that of control group. Conclusion: Findings indicated that this study would contribute to application of aerobic exercise as nursing intervention for the people with high blood pressure.
