Objective To evaluate the effects of different non-pharmacological interventions on postpartum depression,and to provide the evidence for the formulation of relevant intervention programs.Methods Databases,including China National Knowledge Infrastructure(CNKI),China Biomedical Literature Database,Wanfang Database,VIP database,PubMed,EMBase,the Cochrane Library,were systematically searched for randomized controlled trials(RCT)on the effects of non-pharmacological interventions on postpartum depression.The search time limit was from the establishment of the database to July 2022.Network meta-analysis was performed using Stata17.0 and Review Manager 5.3 software.Results A total of 43 studies were included,including 14 non-pharmaceutical interventions,involving 4451 parturients.The results of network meta-analysis showed that compared with the usual care group,exercise therapy[SMD=-5.41,95％CI(-6.94,-3.89),P＜0.001],cognitive behavioral therapy[SMD=-4.72,95％CI(-6.13,-3.31),P＜0.001],acupuncture and moxibustion[SMD=-4.52,95％CI(-8.01,-1.03),P＜0.001]and the comprehensive psychotherapy[SMD=-4.64,95％CI(-8.53,-0.75),P＜0.001]had better improvement effects on postpartum depression.The results of the area under the cumulative rank probability map showed that exercise was the best non-pharmacological intervention to improve postpartum depression.Conclusion Exercise has the best effect on improving postpartum depression,and it is recommended that clinical nursing care should be prioritized.However,a large number of high-quality RCTs are still needed for verification.
