Purpose: The purpose of this study was to determine the effects of 6 months lifestyle coaching program for adults with hypertension. Methods: The study utilized the one-group pretest-posttest design. The subjects were recruited from a corporation group member of a private health maintenance organization. The data of 35 subjects who completed the program out of initial 114 subjects were analyzed for this study. The program included 6 times of monthly face-to-face visits and additional short messages by cellular phone. They were given education for self-management of hypertension and coaching for lifestyle modification. Dependent variables were measured at the beginning and at the end of 6months program and compared by paired t-test. Results: There were significant reductions in systolic and diastolic BP, BMI, total cholesterol, and fasting blood sugar. Among the variables in life style, significant changes were shown in alcohol consumption (frequency and quantity) and exercise (frequency and duration). Conclusion: This study showed that 6 months lifestyle coaching program has potential for positive outcomes on BP control and modifying lifestyle for adults with hypertension. However, additional study is needed to find sustainability of lifestyle and the long-term effect of the program with larger sample.
