Meanings and perceptions of women regarding the practice of yoga in pregnancy: A qualitative study

The Effect of Yoga Practice on Labor Pain: A Systematic Review and Meta-Analysis

Background

Labor pain management is a critical aspect of midwifery care and an essential purpose of childbirth-related care. There is a need for comprehensive results on relevant non-therapeutic methods of reducing labor pain. This systematic review and meta-analysis study was conducted to investigate the effect of yoga practice on labor pain.

Material and Methods

We performed a systematic literature search from SCOPUS, PubMed, Web of Science, and Science Direct for relevant studies from January 1, 1990 to June 2, 2022. We selected published quasi-randomized and randomized controlled trial studies that evaluated the effect of yoga practice on labor pain. Quality research was applied. We pooled the Standardized Mean Dfference (SMD) of labor pain in pregnant women with and without yoga practice during pregnancy using a random-effects model at 95% Confidence Intervals (CIs).

Results

Nine studies including 660 women were included in the meta-analysis. Pregnant women in the yoga practice group experienced statistically significantly low labor pain at the beginning of the active phase compared to the control group (SMD: -1.10, 95% CI: -1.61, -0.58, p < 0.001; I2 = 89%). Yoga interventions also reduced the intensity of labor pain in active (SMD: -1.32, 95% CI: -2.03, -0.60, p < 0.001; I2 = 92%) and transition (SMD: -1.93, 95% CI: -2.87, -0.99, p < 0.001; I2 = 92%) phases compared to the control group, respectively.

Conclusions

The results of the study showed that yoga practice during pregnancy reduces the intensity of labor pain in different labor phases. However, these findings should be considered cautiously due to the substantial heterogeneity between studies.

Prenatal Yoga-Based Interventions May Improve Mental Health during Pregnancy: An Overview of Systematic Reviews with Meta-Analysis

An overview of systematic reviews with meta-analysis was developed to summarize evidence on the effectiveness of prenatal yoga-based interventions on pain, psychological symptoms, and quality of life during pregnancy. CINAHL (via EBSCOhost), Embase, PubMed, SPORTDiscus (via EBSCOhost), and the Cochrane Library were searched from inception to 15 December 2022. The intervention of interest was any prenatal yoga-based intervention. Pain, psychological symptoms, and quality of life were considered as outcome measures. The methodological quality of systematic reviews was judged using AMSTAR 2. The primary study overlap among systematic reviews was evaluated, building a citation matrix and calculating the corrected covered area (CCA). A total of ten systematic reviews, including fifteen meta-analyses of interest and comprising 32 distinct primary clinical trials, were included. Meta-analyses on pain and quality of life were not found. Most meta-analyses (93%) showed that prenatal yoga-based interventions are more effective than control interventions in reducing anxiety, depression, and stress symptoms. However, the overall methodological quality of systematic reviews was judged as critically low, and primary study overlap among systematic reviews was very high (CCA = 16%). Altogether, prenatal yoga-based interventions could improve the mental health of pregnant women, although due to the important methodological flaws that were detected, future systematic reviews should improve their methodological quality before drawing firm conclusions on this topic.

Effect of yoga on posttraumatic growth and quality of life in first-time mothers: A randomized controlled trial

AIM

This study aims to examine the effect of yoga on posttraumatic growth and quality of life in postpartum mothers.

METHODS

The study was conducted as randomized controlled. There were 160 participant mothers, including 80 for the yoga group and 80 for the control group. Mothers in the yoga group participated in individual yoga practices at their homes every weekday for 10 weeks. The personal information form, posttraumatic growth inventory (PTGI), and short form-36 (SF-36) Quality of Life Scale were used to collect data.

RESULTS

The results showed that total and subscale mean scores of the PTGI were higher in the yoga group than the control group after the intervention. In comparison to the control group, the mean scores of the yoga group were higher in subscales as physical functioning, role-physical, bodily pain, general health, vitality, social functioning, mental health of the SF-36, after the intervention.

CONCLUSION

The yoga increased psychological growth and quality of life in the postpartum period. Health professionals could use yoga to increase the quality of life of mothers and to ensure their psychological growth in health care.
