AIM: To quantify the effect of mind-body interventions on stress in pregnant women. DESIGN: A systematic review and meta-analysis of randomized controlled trials was performed. DATA SOURCES: PubMed, Embase, CENTRAL, Web of Science and PsycINFO were searched from each database inception to January 2020. REVIEW METHODS: Randomized controlled trials regarding mind-body interventions for stress in pregnant women were included. Methodological quality was evaluated using the Cochrane Collaboration 'Risk of Bias' tool and meta-analysis was performed via RevMan 5.3. Subgroup analysis and publication bias assessment were conducted. Post hoc sensitivity analysis was performed to investigate the source of heterogeneity. RESULTS: In total, 28 studies comprising 1944 participants were included. The overall meta-analysis showed that antenatal stress of pregnant women in the mind-body interventions groups showed significant high improvements (SMD=-0.94; 95% CI [-1.25, -0.63]; p < .00001) compared with the control groups. Results of subgroup analyses indicated that all types of mind-body interventions including mindfulness intervention, cognitive behavioural therapy, relaxation techniques and yoga were beneficial to antenatal stress. Both groups and individual formats mind-body interventions were effective. 4-8 weeks mind-body interventions were seemed as the optimal choice. Moreover, mind-body interventions were concomitant with reducing antenatal anxiety and depression. CONCLUSION: Mind-body interventions are promising approaches for stress reduction in pregnant women. Nevertheless, the results should be interpreted with caution because of high heterogeneity and publication bias. Further high-quality studies are needed to verify the findings. IMPACT: Mind-body interventions have been widely implemented to ameliorate antenatal stress, but conflicting results were found across studies. This systematic review and meta-analysis suggested that mind-body interventions are relatively safe and convenient and can successfully promote antenatal stress. The suggestions proposed in this review may be useful for developing a scientific mind-body interventions regimen and encouraging the application of mind-body interventions in pregnant women, thereby managing antenatal stress effectively.
