Effect of Pranayama on Perceived Stress, Well Being and Quality of Life of Frontline Healthcare Professionals on Covid-19 Duty: A Quasi- Randomized Clinical Trial

A quasi-randomized clinical trial with 250 frontline healthcare professionals in New Delhi found that a 28-day Pranayama module (twice daily) reduced perceived stress more than routine physical activity. The intervention group showed a significant decrease in perceived stress scores compared to controls. Wellbeing increased non-significantly. Overall quality of life improved non-significantly, but the psychological domain of quality of life increased significantly. Physical and environmental domains also improved but not significantly.

Abstract

Background The COVID-19 pandemic has brought unparalleled challenges for health systems worldwide, the impact of which has also been borne by the Healthcare Professionals (HCPs). Numerous studies have revealed the positive effects of Pranayama and Meditation on mental health. The effect of Pranayama in improving mental health of frontline HCP exposed to Covid-19 patients has not been studied. Aim & Objective: This quasi-randomized clinical trial was done to study the effect of especially designed Pranayama protocol on perceived stress, wellbeing and quality of life of frontline health care professionals who were exposed to COVID-19 patients in hospital settings. Methodology This study was done with 280 frontline healthcare professionals (HCP) assigned duties with COVID-19 patients during September-November, 2020 in 5 government hospitals and COVID-19 quarantine/isolation centres in New Delhi, India. The HCPs were first assessed for COVID-19 infection in the past using antibody test, and only those found negative were recruited. The enrolled respondents were randomly assigned to two arms an intervention arm where there were to practice 28 day Pranayama module (morning and evening sessions) under supervision of a trainer and a Control arm where the HCPs continued routine physical activity (walking jogging etc). Baseline and end-line (total: 250 HCPs) Psychological parameters of Perceived Stress, Well Being and Quality of Life were collected through self-reported questionnaires. Results The intervention (HCPs 123) and control (HCPs 127) groups (Total 250) were comparable in their demographic profile and baseline characteristics. Intervention with Pranayama module led to a significant reduction (Mean diff -2.46 P-value 0.028) in perceived stress score in the intervention group compared to the control group. The wellbeing index in Interventional group intervention showed a non-significant increase. The WHO Quality-of-life score increased in the intervention group as compared to the controls (mean difference 2.78, p-value: 0.17). Of its four components, the one for Psychological domain increased significantly (mean diff: 1.52, P-value: 0.019), while those for Physical domain and Environmental domains increased (mean diff: 0.64, P-value: 0.29 and mean diff: 0.68, p-value: 0.48) though not statistical significantly. Conclusion: The intervention of twice daily practice of the Pranayama module for 28 days in frontline HCPs performing COVID-19 duties had a noteworthy effect in lowering Perceived Stress, improving perceived Quality of life, especially its Psychological domains as measured through standardized questionnaires.
