Traditional Chinese acupuncture and postpartum depression: A systematic review and meta-analysis.

Abstract

Acupuncture, a key component of traditional Chinese medicine, is a form of alternative medicine in which thin needles are inserted into the body commonly for pain relief. To date, the role of traditional Chinese acupuncture in mood disorders in the postpartum period is unclear. Thus, this study aimed to review the effectiveness of acupuncture in patients with postpartum depression (PPD). We searched databases such as PUBMED, EMBASE, and Cochrane Controlled Trials Register until September 2018. Meta-analysis was performed using Comprehensive Meta-Analysis 2.0 software. The mean difference (MD) and risk ratio (RR) with 95% confidence intervals (CI) were calculated to evaluate the results of each comparison. A total of 887 PPD patients from 12 randomised controlled trials were included in the quantitative meta-analysis, with 443 patients in the treatment group and 444 patients in the control group. Patients in the acupuncture group had significantly better performances assessed by the Hamilton Depression Scale than those in the control group, and the pooled MD was -1.27 (95% CI: -2.55 to 0.01; p = 0.05, I = 83%) in the random-effect model. In addition, significantly better performance in the effective rate was observed in the acupuncture group than in the control group, and the pooled RR was 1.20 (95% CI: 1.09 to 1.33; p < 0.0001, I = 46%). However, in subgroup analysis for the acupuncture therapy alone, only effective rate showed a significantly better performance. Traditional Chinese acupuncture seems to be effective in improving some symptoms of PPD, although the evidence is uncertain. Therefore, further studies following standardized guidelines with a low risk of bias are needed to confirm the effectiveness of acupuncture in the treatment of PPD.
