Abstract
BACKGROUND

Depression is recognized as a major public health problem with a substantial impact on individuals and society. Complementary therapies such as acupressure may be considered a safe and cost-effective treatment for people with depression. An increasing body of research has been undertaken to assess the effectiveness of acupressure in various populations with depression, but the evidence thus far is inconclusive.

AIM

To examine the efficacy of acupressure on depression.

METHODS

A systematic literature search was performed on PubMed, PsycINFO, Scopus, Embase, MEDLINE, and China National Knowledge (CNKI). Randomized clinical trials (RCTs) or single-group trials in which acupressure was compared with control methods or baseline in people with depression were included. Data were synthesized using a random-effects or a fixed-effects model to analyze the impacts of acupressure treatment on depression and anxiety in people with depression. The primary outcome measures were set for depression symptoms. Subgroups were created, and meta-regression analyses were performed to explore which factors are relevant to the greater or lesser effects of treating symptoms.

RESULTS

A total of 14 RCTs (1439 participants) were identified. Analysis of the between-group showed that acupressure was effective in reducing depression [Standardized mean differences (SMDs) = -0.58, 95%CI: -0.85 to -0.32, P < 0.0001] and anxiety (SMD = -0.67, 95%CI: -0.99 to -0.36, P < 0.0001) in participants with mild-to-moderate primary and secondary depression. Subgroup analyses suggested that acupressure significantly reduced depressive symptoms compared with different controlled conditions and in participants with different ages, clinical conditions, and duration of intervention. Adverse events, including hypotension, dizziness, palpitation, and headache, were reported in one study.

CONCLUSION

The evidence of acupressure for mild-to-moderate depressive symptoms was significant. Importantly, the findings should be interpreted with caution due to study limitations. Future research with a well-designed mixed method is required to consolidate the conclusion and provide an in-depth understanding of potential mechanisms underlying the effects.

Keywords: Acupressure; Depression; Mild-to-moderate depressive symptoms; Systematic review; Meta-analysis

Core Tip: Acupressure is effective on mild-to-moderate depressive symptoms. However, no confirmed evidence is available about the impacts of acupressure on patients with severe depressive disorders. This is the first study investigating the impacts of acupressure on depression among clinical and general populations.
