Acupuncture for subthreshold depression: a randomized controlled trial
This study investigates whether acupuncture can help people with subthreshold depression, a condition where individuals experience depressive symptoms but do not meet the full criteria for major depression.

Introduction
Acupuncture has shown promise for SD, though its efficacy beyond placebo remains unclear. The mean reduction in HAMD-17 scores from baseline to week 8 was -7.28 (95% CI, -8.26 to -6.3) in the VA group and -3.80 ( 95% CI, -4.42 to -2.77) in the SA group.
The between-group difference at week 8 was -4.08 (95% CI, -5.15 to -3.02; P < .001).

Acupuncture has shown promise for SD, though its efficacy beyond placebo remains unclear.
However, there are currently limited data directly comparing the efficacy of acupuncture versus SA in treating SD.
Research Question
To further explore this hypothesis, stool and plasma samples were collected both at baseline and week 8 as part of the study design, with the aim of conducting microbiome and metabolomic analyses to investigate potential mechanisms underlying acupuncture\u2019s effects in SD.
Methodology
Results Of 231 screened patients, 64 participants (71.87% female; mean age, 29.83 [SD 6.84] years) were included. Fifty-nine participants (92.2%) completed the study.
Study Design
Meta-analysis results indicate that psychotherapy, especially cognitive behavioral therapy (CBT), may be the most effective nonpharmacological intervention to improve SD in adults , but it requires considerable time and financial investment.
Additionally, a systematic review and individual participant data meta-analysis demonstrated that psychological interventions yield small to moderate benefits and can significantly reduce the risk of progression to MDD .

Results & Findings
Abstract Background Subthreshold depression (SD), characterized by depressive symptoms not meeting major depressive disorder (MDD) criteria, poses a significant risk for MDD development. Conclusions Acupuncture demonstrated significant therapeutic effects for SD compared to SA, with benefits extending beyond placebo.

- Conclusions Acupuncture demonstrated significant therapeutic effects for SD compared to SA, with benefits extending beyond placebo.
- These findings support acupuncture as a specific and effective intervention for SD.
- However, the study’s limitations, including its single-center design and relatively young sample, should be considered when generalizing the results.

Practical Applications
Background Subthreshold depression (SD) characterized by depressive symptoms that do not meet the criteria for major depressive disorder (MDD), may coexist with or transition into MDD over time . Interestingly, the SA group also demonstrated a reduction in HAMD17 scores at week 8, which may reflect non-specific placebo responses or the natural tendency of remission in SD.
Moreover, given that individuals with SD are often more sensitive and skeptical, we were concerned that non-penetrating placebo needles might compromise blinding credibility.
Nonetheless, we acknowledge that including a \u201cdon\u2019t know\u201d option could provide additional information on uncertainty, and we will consider this refinement in future studies.
Background
Subthreshold depression (SD) is a condition with depressive symptoms that do not meet major depressive disorder (MDD) criteria, posing a risk for developing MDD. The prevalence of SD is notably high, and it is linked to increased suicide risk and cardiovascular issues. Non-pharmacological treatments, particularly acupuncture, are being explored as effective interventions.
Participants
Inclusion criteria for participants included being aged 18-60, diagnosed with SD, and having specific HAMD-17 scores. Exclusion criteria involved various mental health disorders, severe medical conditions, and recent treatments that could affect results.

The between-group difference at week 8 was -4.08 (95% CI, -5.15 to -3.02; P < .001). To further explore this hypothesis, stool and plasma samples were collected both at baseline and week 8 as part of the study design, with the aim.

The selection of acupoints was based on the Evidence-Based Guidelines of Clinical Practice with Acupuncture and Moxibustion for Depression (Revised) , and was further adapted according to the clinical experience of our research team. Acupuncture has been shown to modulate brain function.
Therefore, we designed this study to evaluate the efficacy of verum acupuncture (VA) compared to sham acupuncture (SA) for SD. Therefore, Prompt recognition, diagnosis, and management of SD are crucial for preventing its escalation to MDD, thereby mitigating its impact on health.
Acupuncture has shown promise for SD, though its efficacy beyond placebo remains unclear. However, there are currently limited data directly comparing the efficacy of acupuncture versus SA in treating SD.
