Effect of Community-Based Structured Yoga Program on Hba1c Level among Type 2 Diabetes Mellitus Patients: An Interventional Study

Effect of Structured Yoga Program on Stress and Well-being Among Frontline Healthcare Workers During COVID-19 Pandemic

CONTEXT

Frontline healthcare workers are at risk of developing psychological distress during a pandemic. Yoga, a form of mind-body medicine can reduce body stress and increases well-being.

AIMS

To assess the effect of yoga on the stress and well-being of healthcare workers during the COVID-19 pandemic.

SETTINGS AND DESIGN

This single-arm pre-post study was conducted among frontline health workers (support staff, paramedics, and medics) posted at a secondary care hospital in a North Indian district.

METHODS AND MATERIALS

Basic demographic details, blood pressure, anthropometric variables like height, weight, and biochemical variables like glycosylated hemoglobin (Hb1Ac), fasting and post-prandial blood sugar, lipid profile, serum cortisol, and C-reactive protein were measured. Stress levels were assessed using the depression anxiety and stress scale (DASS)-21 while well-being was assessed using the World Health Organization (WHO)-5 well-being scale. Twelve weeks of supervised yoga session was provided for 1 hour per session, 3 times per week.

STATISTICAL ANALYSIS

The mean value was compared from baseline to post-intervention with paired t-test/Wilcoxon signed rank test.

RESULT

A total of 89 participants were enrolled, 53 (59.5%) being male. Two-thirds of the participants were aged 20-39 years. During follow-up, 80 participants completed 12 weeks of yoga sessions. Post-intervention DASS-21 score decreased and WHO-5 increased significantly. The glycosylated hemoglobin (HbA1c) level and cholesterol-HDL ratio decreased significantly. Other variables didn't change significantly. No adverse effects were reported by the participants.

CONCLUSION

Supervised structured yoga sessions helped decrease stress, depression, and anxiety and improved well-being. Therefore, it can be a feasible strategy to manage workplace-related stress and phycological morbidities.

A Study to Evaluate the Effect of a Combined Approach of Yoga and Diet in High-risk Cardiovascular Subjects

Background

Cardiovascular disease (CVD) is a group of disorders of the heart and blood vessels, including coronary heart disease, cerebrovascular disease, rheumatic heart disease, peripheral artery disease, congenital heart disease, deep vein thrombosis, and pulmonary embolism.

Aim

The aim of this study was to assess cardiovascular risk factors and evaluate the effectiveness of combined approach of yoga and diet in reducing cardiovascular risk factors among high-risk subjects.

Materials and Methods

This interventional study was conducted at RUHS College of Medical Sciences and Associated Hospitals, Jaipur, on the high-risk population of either sex in the age group of 40-70 years. QRISK3 web calculator was used as the method of measurement for outcome of interest. The combined approach of yoga intervention includes yogic asanas and pranayamas and dietary modification.

Results

This study compared physiological parameters (blood pressure) and biochemical parameters (fasting blood sugar, glycosylated hemoglobin, lipid profile) at baseline, three months and six months after yoga and diet intervention in participants who were at high-risk of cardiovascular disease development in future and were found to be having significantly decreased systolic blood pressure (P=0.000), fasting blood glucose (P=0.000), glycosylated hemoglobin (HbA1C) (P=0.011), total cholesterol-high density lipoprotein ratio (P=0.000), low density lipoprotein (P=0.009), triglyceride (P=0.034), and QRISK3 Score (P=0.000) after combined approach of yoga and diet.

Conclusions

This study concluded that the short-term combined approach of yoga-based life-style intervention and diet reduced cardiovascular risk factors in subjects at high-risk of developing cardiovascular disease.

The Effect of Yoga on the Lipid Profile: A Systematic Review and Meta-Analysis of Randomized Clinical Trials

Objectives

Yoga is a mind-body stress-relieving exercise that increases mental and physical health, which may have a role in the improvement of metabolic disorders. The present study has reviewed the effect of yoga on lipid profiles as a systematic review and meta-analysis.

Methods

We evaluated the available randomized controlled trials on the effects of yoga-based programs, and lipid profiles by searching PubMed/Medline, Scopus, Web of Science, and the Cochrane central register of control trials up to January 2022. Both fixed and random effect analyses were used to find the relationships. Subgroup analysis was performed based on the continent, duration of the included studies, gender, and health condition of participants to discover the sources of heterogeneity.

Result

Fifty-three studies were included in the current systematic review and meta-analysis with a total sample size of 13,191. There was a striking association between yoga and total cholesterol (−10.31 mg/dl; 95% CI: −14.16, −6.45; I² = 82.5%, P < 0.001), low-density lipoprotein cholesterol (−8.64 mg/dl; 95% CI: −12.03, −5.25; I² = 75.0%, P < 0.001), high-density lipoprotein cholesterol (1.98 mg/dl; 95% CI: 0.81, 3.14; I² = 91.6%, P < 0.001), triglycerides (−13.50 mg/dl; 95% CI: −20.09, −6.92; I² = 90.7%, P < 0.001) and very low-density lipoprotein (−3.94 mg/dl; 95%CI: −6.31, −1.56; I² = 72.2%, P < 0.001).

Conclusion

It seems yoga interventions had a substantial effect on lipid profiles, however, more qualified trials or cohort studies are needed to conclude exactly.
