The Effect of Yoga on Menstrual Disorders: A Systematic Review

The Effect of Yoga on Premenstrual Distress, Quality of Life, and Stress Level

The study aims to evaluate the effect of yoga on the premenstrual syndrome, perceived stress level and the quality of life. The study was conducted as a randomized controlled trial at a university in Turkey. A yoga group = 39, a control group = 41, total of n = 80 female students participated in the study. In the study, firstly, the preview was made, then the yoga group was applied two days a week for eight weeks, the second follow-up was made after the application, and lastly, the last follow-up was made in the 24th week. Four questionnaire surveys were applied on students. When the yoga group compared with the control group in terms of premenstrual syndrome, the quality of life and perceived stress level in the 2nd follow-up, a statistically significant decrease was found in the mean between the menstrual and premenstrual period, and the quality of life increases in the yoga group compared to the control group students. Practicing yoga in university students with premenstrual syndrome reduced premenstrual symptoms and raised quality of life. Yoga can be recommended to girls with premenstrual syndrome (PMS) to reduce PMS and improve quality of life.

The effect of long-term, regular yoga on the pain and quality of life in women with premenstrual syndrome: A randomized controlled, single-blinded trial

Premenstrual syndrome (PMS) has been known to have emotional, physical, and behavioral effects in reproductive age. To evaluate the effects of premenstrual syndrome (PMS) on pain and quality of life in women, who perform regular yoga exercises in the long term. 30 women with PMS and 30 control (31.17 ± 5.28 years old) participated in this randomized controlled, single blinded study. The demographics of the PMS and control groups were similar (p < 0.05). A significant difference was found in a depressive mood, anxiety, fatigue, pain, depressive thoughts, sleeping habits subscales, and total scores of the PMSS, WHOQOL-BREF scale, and VAS scores between yoga and control groups (p < 0.05). It is determined that long-term and regular yoga practice for women with PMS will improve their, PMS symptoms, quality of life, and pain level.

Yoga and Lifestyle Changes: A Path to Improved Fertility - A Narrative Review

Infertility, a widespread medical condition affecting numerous couples globally, persists as a challenge despite advances in assisted reproductive technologies (ARTs), often burdened by financial, physical, and emotional strains. Complementary and alternative approaches, notably yoga, have garnered attention for potentially enhancing fertility outcomes. Studies reveal yoga's influence on factors contributing to infertility, including reduced oxidative stress (OS) and oxidative DNA damage (ODD). OS, linked to mutagenic base formation, higher malondialdehyde levels, abnormal methylation, and altered gene expression, can impair sperm genome integrity. Yoga's efficacy is evident in lowering OS, positively affecting signal transmission, gene expression, and physiological systems. Furthermore, yoga has a positive impact on addressing the dysregulation of apoptosis, resulting in improved processes such as spermatogenesis, sperm maturation, and motility, while also reducing DNA fragmentation. OS correlates with genome-wide hypomethylation, telomere shortening, and mitochondrial dysfunction, contributing to genome instability. Yoga and meditation significantly reduce OS and ODD, ensuring proper reactive oxygen levels and preserving physiological systems. The review explores potential mechanisms underlying yoga's positive impact on infertility, including enhanced blood flow, reduced inflammation, relaxation response, and modulation of the hypothalamic-pituitary-adrenal axis. Furthermore, a comprehensive review of the literature reveals substantial evidence supporting the positive effects of yoga on infertility factors. These include oxidative stress (OS), oxidative DNA damage (ODD), epigenetic changes, hormonal balance, ovarian function, menstrual irregularities, and stress reduction. In summary, yoga emerges as a promising adjunctive therapy for infertility, demonstrating the potential to mitigate key factors influencing reproductive success. Although preliminary evidence indicates the positive effects of yoga on infertility, further clinical research is imperative to define specific benefits, molecular mechanisms associated, optimal protocols, and long-term effects in infertility treatment plans.

Effects of Yoga for Coping with Premenstrual Symptoms in Taiwan-A Cluster Randomized Study

Home-based yoga practice has not been approved as a method for alleviating premenstrual symptoms in Taiwan. This study was a cluster randomized trial. A total of 128 women self-reporting at least one premenstrual symptom were enrolled in the study, of which there were 65 participants in the experimental group and 63 participants in the control group. Women in the yoga group were provided with a yoga DVD program (30 min) to practice for three menstrual months, at least three times a week. All participants were given the Daily Record of Severity of Problems (DRSP) form to measure premenstrual symptoms. After the yoga exercise intervention, the yoga group had statistically significantly fewer and/or less severe premenstrual depressive symptoms, physical symptoms, and anger/irritability. Other disturbances and the impairment of daily routine, hobbies/social activities, and relationships also occurred significantly less often in the yoga group. The study found that yoga is useful to relieve premenstrual symptoms. Moreover, home-based yoga practice is more pertinent in the pandemic era. The strengths and drawbacks of the study are discussed and further study is recommended.

Evaluation of the effectiveness of yoga in management of premenstrual syndrome: a systematic review and meta-analysis

Aim: The management of Premenstrual Syndrome (PMS) is still evolving due to the modest effect sizes of the available treatment modalities. Yoga as therapeutic intervention in PMS has been gathering interest amongst researchers. The current manuscript reviews the evidence surrounding yoga in PMS.Methods: This manuscript was a systematic review and meta-analysis evaluating the effectiveness of yoga on the total scores and sub-domains of PMS after studies were identified using a pre-defined selection criterion after a search in PubMed, Google Scholar, Scopus and Web of Science. Both quantitative and qualitative analysis of the accumulated data was performed. Overall, 14 studies were identified for the review, 11 of which were used for the purpose of quantitative analysis.Results: The studies were heterogenous in terms of the design, yoga regimes, nature of interventions and tools used for outcome measures. It was found that yoga was beneficial in the management of PMS. This benefit was also seen when all the sub-domains of PMS were individually examined except physical sub-domain.Conclusion: Though there were certain limitations in our review like heterogeneity in studies, possibility of publication bias and restrictive selection criterion; it supported that yoga can be beneficial in patients with PMS.

Effect of exercise on symptoms of premenstrual syndrome in low and middle-income countries: a protocol for systematic review and meta-analysis

INTRODUCTION

Premenstrual syndrome (PMS) has the potential to affect the quality of life adversely. Published guidelines recommend the use of exercise as part of the first-line management interventions for PMS. However, the published evidence related to the effectiveness of physical activity and PMS is inconclusive. This review will assess the effectiveness of exercise-based interventions in reducing PMS in women screened or diagnosed with PMS in low and middle-income countries, where the prevalence of PMS is high.

METHODS AND ANALYSIS

Electronic databases will be researched, including Embase, Cochrane Central Register of Controlled Trials, MEDLINE, PsycINFO, Web of Science, ClinicalTrials.gov and Google Scholar. All the studies published until March 2020 will be included. A standardised data extraction form will be used adapted from the Cochrane Handbook of Systematic Reviews of Interventions. Included articles will be assessed using the risk of bias tools based on study design. Data will be analysed using Review Manager V.5.3. The inverse-variance random-effects method will be used to report the standardised mean difference. A meta-analysis will be used only if studies are sufficiently homogenous. A narrative synthesis will be undertaken when studies are heterogeneous. Methodological heterogeneity between studies will be evaluated by considering the study types. Statistical heterogeneity will be tested using the I² test. Subgroup analyses may be performed only for the primary outcome in case of sufficient studies. Sensitivity analysis will be conducted to assess the impact of intervention excluding studies without randomisation and studies with a high risk of bias. Funnel plots will be used to assess the potential reporting bias and small-study effects only when there are more than 10 studies included in the meta-analysis.

ETHICS AND DISSEMINATION

This study does not require ethical approval, as the review is entirely based on published studies. The results will be published and/or will be presented at a pertinent conference.
