Objective: To test the effectiveness of mindfulness training on blood pressure reduction in pre-hypertension people.

Materials and Methods: A randomized control trial was used. Pre-hypertension people with systolic blood pressure (SBP) 130 to 139 and diastolic blood pressure (DBP) 80 to 89 mmHg were randomly assigned to either the intervention with 35 people or the control group also with 35 people. A mindfulness-based brief intervention program (MBBI) was performed for eight weeks. The authors measured the blood pressure at baseline, week 8, 12, and 20. Mixed linear regression was used to test the effect of MBBI.

Results: Seventy participants were included and allocated equally to either the intervention or the control group with 35 participants each. MBBI had the effect of lowering SBP compared to the control group at week 8 (mean difference –3.50, 95% confidence interval –5.13 to –1.87), week 12 (mean difference –5.63, 95% confidence interval –7.25 to –3.99), and week 20 (mean difference –7.81, 95% confidence interval –9.44 to –6.18). For DBP, the authors observed statistically significant decreases only at week 12 (mean difference –3.09, 95% confidence interval –6.15 to –0.02).

Conclusion: The authors observed the effect of a MBBI on decreasing SBP and DBP.
