Mindfulness-based intervention for hypertension patients with depression and/or anxiety in the community: a randomized controlled trial.

Summary

Mindfulness-based therapy significantly reduces symptoms of depression and anxiety in patients with hypertension, with a 21.1% decrease in depression scores and a 17.8% decrease in anxiety scores. In a study involving 60 participants, systolic blood pressure dropped by an average of 12.24 mm Hg after a 10-week intervention. Additionally, self-efficacy improved notably among those receiving mindfulness training compared to the control group. This approach offers a promising strategy for managing both mental health and hypertension effectively.

Abstract

To evaluate mindfulness-based intervention for hypertension with depression and/or anxiety. 10-week mindfulness-based intervention, including health education for hypertension, exclusively for the control group, was administered to the intervention group to assist sixty hypertension patients with depression/anxiety. Among them, the intervention group comprised 8 men and 22 women, with a mean age of 60.02 years and a mean duration of hypertension of 6.29 years. The control group consisted of 14 men and 16 women with a mean age of 57.68 years and a mean duration of hypertension of 6.32 years. The severity of depressive and/or anxiety symptoms was assessed using the 9-item Patient Health Questionnaire (PHQ-9) and the 7-item Generalized Anxiety Disorder scale (GAD-7), along with blood pressure (BP) measurements taken twice daily. The study utilized a self-made self-efficacy scale and awareness of physical and mental health to evaluate mental health and state. The depression PHQ-9 or GAD-7 scores reduced by 21.1% or 17.8% in the mindfulness-based intervention group, compared to the control (Z = -2.040, P = 0.041) post 10-week period, suggesting significant reduction in anxiety/stress. These results were consistent with a reduction in systolic BP of 12.24 mm Hg (t = 6.041, P = 0.000). The self-efficacy score of the mindfulness intervention group significantly improved compared to the control (t = 7.818, P < 0.001), while the awareness of physical and mental health in the mindfulness intervention group significantly improved compared to the control (χ2 = 5.781, P = 0.016). Mindfulness-based, short-term focused interventions provide modest relief for depression and/or anxiety and are effective in lowering blood pressure and improving self-efficacy scores.
