Association between long COVID, functional activity, and health-related quality of life in older adults 2023 Shanbehzadeh et al

Abstract

Background
Older adults experience persistent symptoms post-COVID-19, termed as Long COVID, affecting their physical and mental health. This study aimed to evaluate the effects of Long COVID, level of physical activity, and functional decline on older adults’ health-related quality of life post-COVID-19.

Methods
This cross-sectional study was conducted on 121 older adults with 60 to 90 years old post-coronavirus infection. The standardized metrics used in the study were Fatigue Severity Scale, Physical Activity Elderly, SF12, Post-COVID-19 functional status scale, and COVID-19 Yorkshire rehabilitation screening scale. The severity of coronavirus infection was evaluated by changes in chest CT scan images and O2 saturation at hospital admission. Data were analyzed using linear regression analyses.

Results
The results of regression analysis revealed six factors to be predictors of physical health at 6 months post-COVID-19 (F = 9.046, P < 0.001; explained variance 63%), which the significant factors were fatigue, level of physical activity, worsened pain, difficulties in activities of daily living and cognitive-communication problems. Among these factors, greater fatigue and worsened pain intensity were the strongest predictors. Mental health was associated with days of hospitalization and cognitive-communication problems (F = 2.866, P < 0.001; explained variance 35%).

Conclusions
Considering the negative impact of fatigue, pain, low physical activity, and cognitive-communication problems on health-related quality of life, early and accurate evaluation and management are required for recovered older adults post-COVID-19.
