A Meta-Analysis on the Effectiveness of Prenatal Yoga in Reducing Cortisol Hormone in Pregnancy
ABSTRACT Backgrund: A growing body of evidence suggests that activity of the stress-responsive hypothalamic-pituitary-adrenal axis and its end-product cortisol also may be associated with perinatal emotional well-being. A number of preventive interventions, such as Yoga, targeting psychosocial and physiological risk factors for perinatal depression have utilized mind-body practices, which embody the idea that the mind interacts with the body to influence physical functioning, improve symptoms, and promote health. This study aimed to investigate effectiveness of prenatal yoga in reducing cortisol hormone in pregnancy Subjects and Method: This was a meta-analysis and systematic review. This study collected published articles during 2000 to 2020 from PubMed, Science Direct, Springer, Proquest, and Chocrane electronic databases. The inclusion criteria were full text, randomized controlled trial, and prenatal yoga intervention. The study subjects were pregnant women who received prenatal yoga for 8 to 20 weeks. Outcome was cortisol hormone reduction during pregnancy. The selected articles were analyzed by PRISMA flow chart and RevMan 5.3. Results: 5 articles from America and Asia were met the inclusion criteria. This study had high heterogeneity (I2=88%; p<0.001). Therefore, this study used random effect model (REM). Prenatal yoga reduced cortisol level 0.59 times in pregnancy (Mean Difference= -0.59; 95% CI= 1.18 to 0.01; p= 0.050). Conclusion: Prenatal yoga is effective to reduce cortisol level in pregnant women. Keywords: prenatal yoga, cortisol hormone, pregnant women Correspondence: Shiva Aflahiyah.
