Objective To evaluate the clinical efficacy of acupuncture in treatment of postpartum depression. Methods Pubmed database and Embase database were retrieved online in English, and China National Knowledge Internet (CNKI), China Biology Medicine disc (CBM), VIP database and Wanfang Data were retrieved in Chinese. Literature in recent 10 years relating to clinical randomized controlled trials of acupuncture in treatment of postpartum depression were collected, and Meta analysis was performed by adopting RevMan5.3. Results Fourteen articles were included in the study in total; it was shown from HAMD result that after combination, WMD=-2.27, 95%CI (-2.55, 0.01); according to Z-test, Z=2.95, P=0.05, and the difference in efficacy between treatment group and control group was statistically significant. It was shown from EPDS result that after combination, WMD=-0.53, 95%CI (-0.92, -0.03); according to Z-test, Z=2.08, P〈0.05, and the difference in efficacy between treatment group and control group was statistically significant. During the analysis taking estradiol as standard, it was shown from the result that after combination, WMD=63.99, 95%CI (13.39, 114.60); according to Z-test, Z=2.48, P〈0.05, and the difference in efficacy between treatment group and control group had remarkably statistical significance. During the analysis taking effective rate as standard, it was shown from the result that after combination, OR=3.15, 95%CI (2.19, 4.55); according to Z-test, Z=6.14, P〈0.05, and the difference in efficacy between treatment group and control group had remarkably statistical significance. Conclusion Acupuncture treatment for postpartum depression is effective, but more clinical randomized controlled trials with high quality and large sample size are still needed to verify the result.
