The effectiveness and characteristics of pregnancy yoga interventions: a systematic review protocol

Stress and cardiovascular risk burden after the pandemic: current status and future prospects

INTRODUCTION

The recent COVID-19 pandemic has induced an increase in anxiety, stress, and depression in the world population, prompting a reevaluation of these well-known risk factors on cardiovascular burden.

AREAS COVERED

This short report analyzes the impact of the pandemic on stress and depression, highlighting how the phenomenon has particularly affected women and highlights the strategies that can be undertaken after the pandemic to reduce stress and depression. We have analyzed the pandemic because it has completely changed the scenario of cardiovascular risk factors with an important increase in socio-economic stressors.

EXPERT OPINION

It is still difficult to assess the damage produced on cardiovascular risk just as it is almost impossible to predict how the overwhelming and important increase in Long-Covid Syndromes will impact the population. Strong action is needed to support critical situations and to implement social campaigns aimed at restoring healthy lifestyles. Physical activity can be an easy and inexpensive tool to help cope with stress and depression.

The characteristics and effectiveness of pregnancy yoga interventions: a systematic review and meta-analysis

Background

Yoga is a popular mind-body medicine frequently recommended to pregnant women. Gaps remain in our understanding of the core components of effective pregnancy yoga programmes. This systematic review and meta-analysis examined the characteristics and effectiveness of pregnancy yoga interventions, incorporating the FITT (frequency, intensity, time/duration and type) principle of exercise prescription.

Methods

Nine electronic databases were searched: MEDLINE, PsycINFO, EMBASE, CINAHL, WHOLiS, AMED, ScieLo, ASSIA and Web of Science. Randomised control trials and quasi-experimental studies examining pregnancy yoga interventions were eligible. Covidence was used to screen titles, abstracts, and full-text articles. Outcomes of interest were stress, anxiety, depression, quality of life, labour duration, pain management in labour and mode of birth. The Cochrane Collaboration’s Risk of Bias Assessment tool was used to assess methodological quality of studies and GRADE criteria (GRADEpro) evaluated quality of the evidence. Meta-analysis was performed using RevMan 5.3.

Results

Of 862 citations retrieved, 31 studies met inclusion criteria. Twenty-nine studies with 2217 pregnant women were included for meta-analysis. Pregnancy yoga interventions reduced anxiety (SMD: -0.91; 95% CI: − 1.49 to − 0.33; p = 0.002), depression (SMD: -0.47; 95% CI: − 0.9 to − 0.04, P = 0.03) and perceived stress (SMD: -1.03; 95% CI: − 1.55 to − 0.52; p < 0.001). Yoga interventions also reduced duration of labour (MD = − 117.75; 95% CI − 153.80 to − 81.71, p < 0.001) and, increased odds of normal vaginal birth (OR 2.58; 95% CI 1.46–4.56, p < 0.001) and tolerance for pain. The quality of evidence (GRADE criteria) was low to very low for all outcomes. Twelve or more yoga sessions delivered weekly/bi-weekly had a statistically significant impact on mode of birth, while 12 or more yoga sessions of long duration (> 60 min) had a statistically significant impact on perceived stress.

Conclusion

The evidence highlights positive effects of pregnancy yoga on anxiety, depression, perceived stress, mode of birth and duration of labour.
