Abstract 17390: The Impact of The Covid-19 Pandemic on Perceived Stress in Rural Caregivers Participating in a Cardiovascular Risk Reduction Intervention

Abstract

Introduction: Interventions to reduce cardiovascular disease (CVD) risk factors are key for improving the health and well-being of rural caregivers who are often referred to as invisible patients. The Rural Intervention for Caregivers’ Heart Health (RICHH), a CVD risk reduction intervention (2017-2022) included a stress management module. The COVID-19 pandemic (2020-2021) had an unknown impact on this intervention on perceived stress. The aim of this study was to determine whether the COVID-19 pandemic moderated the effects of RICHH on perceived stress for rural caregivers. Methods: This was a randomized controlled trial of a CVD risk reduction intervention that promoted self-care. Caregivers were randomized to usual care or the RICHH intervention. Data were collected at baseline, 4 and 12 months. Participants were grouped into two groups by COVID-19 timing: 1) the pre-pandemic group (n=145) completed the study before the pandemic; and 2) the pandemic group (n=114) completed the study during the pandemic. A piecewise linear mixed-effect model was used to evaluate the impact of the intervention and COVID-19 timing on perceived stress (Cohen’s Perceived Stress Scale). Results: The effect of the intervention on perceived stress in 259 participants (mean age = 55 ± 13 years, 78% female, 95% white, and 73 % married) was significant in the pandemic group (β= -.59, SE = .14, P < .001) but not in the pre-pandemic group (β = -.10, SE = .13, P = .45 [Figure1). The differences in perceived stress changes between the pre-COVID and during-COVID groups was significant, indicating a moderating effect of COVID (β = -.50, SE = .19, P = .009). Conclusion: The RICHH intervention helped to mitigate stress during the COVID-19 pandemic among those in the intervention group at the 4 months, however this effect was not sustained at 12 months. It remains unclear if the reduction in perceived stress during the pandemic was due to participation in the intervention or weekly contact with an interventionist.
