高血圧患者に対する音楽療法の有効性：システマティックレビューとメタアナリシス

This study aimed to comprehensively evaluate the efficacy of music intervention as a non-pharmacological approach for improving physiological and psychological outcomes in patients with hypertension through a systematic review and meta-analysis of randomized controlled trials (RCTs).

We systematically searched PubMed, Embase, The Cochrane Library, Web of Science Core Collection, Wanfang Data, and CNKI for RCTs investigating the effects of music therapy on blood pressure, heart rate (HR), anxiety, and depression in hypertensive adults. Data were pooled using random-effects models, and weighted mean differences (WMDs) with 95% confidence intervals (CIs) were calculated. The robustness of findings was assessed via sensitivity analysis, and publication bias was evaluated using Egger's and Begg's tests.

Twenty-one RCTs involving 1436 participants were included. Meta-analysis revealed that music intervention significantly reduced systolic blood pressure (SBP) (WMD = -8.26 mmHg, 95% CI: -10.56 to -5.96), diastolic blood pressure (DBP) (WMD = -5.91 mmHg, 95% CI: -8.03 to -3.79), HR (WMD = -4.17, 95% CI: -7.22 to -1.12), anxiety levels (measured by Self-Rating Anxiety Scale, SAS) (WMD = -5.22, 95% CI: -7.03 to -3.40), and depression levels (measured by Self-Rating Depression Scale, SDS) (WMD = -7.12, 95% CI: -10.27 to -3.98). Sensitivity analyses confirmed the stability of these findings, and statistical tests showed no significant publication bias for primary outcomes.

Music therapy is an effective complementary intervention for reducing blood pressure, HR, anxiety, and depression in hypertensive patients. Personalized music selections and longer intervention sessions may enhance efficacy. Future research should focus on standardizing intervention protocols, clarifying underlying mechanisms, and exploring long-term efficacy.
