Comparison of Relaxation Techniques, Routine Blood Pressure Measurements, and Self-Learning Packages in Hypertension Control

Abstract

Background.Even though the effectiveness of meditation and relaxation skills is controversial in blood pressure control, extensive field studies are limited. A national study targeting 50 communities randomly selected from northern Taiwan was conducted to test and compare the effectiveness of hypertension control incorporating three strategies.Methods.Five hundred ninety hypertensives identified from 3,128 adults at a screening survey among the 50 communities were invited to participate in the study and were randomly assigned to three treatment modalities, (a) relaxation techniques training at home, (b) routine blood pressure measurement by a health professional, and (c) reading self-learning packages, or to a control group.Results.After a 2-month intervention period, the three treatment groups showed a significant reduction in systolic blood pressure levels compared with the control group (11.O mm Hg for group 1, 9.2 mm Hg for group 2, and 5.1 mm Hg for group 3). The relax-ation group had the most significant reduction insystolic blood pressure levels, followed by the rou-tine blood pressure monitoring group and the self-learning group. However, the effect of relaxation training at home was not significantly greater than routine blood pressure measurement by a health professional.
