The impact of wildtype SARS-CoV-2 on fatigue and quality of life: prevalence of post COVID-19 condition in a Dutch population-based serosurveillance cohort. (preprint)

ABSTRACT

Background: Our aim was to assess the relationship between (time since) wild-type SARS-CoV-2 infection and health-related quality of life (HRQoL) and fatigue as endpoints linked to Post COVID-19 condition (PCC). Methods: Participants [≥]15 years were selected from the February 2021 round of the population-based PIENTER Corona study. We investigated the association between (time since) SARS-COV-2 infection and health outcomes: HRQoL (health utility (SF-6D); physical health and mental health (both SF-12)) and fatigue (CIS-fatigue) using multivariable logistic regression analyses adjusted for age, sex, educational level, number of comorbidities, COVID-19 vaccination status, and the intensity of restrictions. For each outcome, multivariable logistic regression models were fitted at cut-off points selected based on the cumulative distribution of those uninfected. Results: Results shown correspond to the cut-off point related to the worst off 15% of each outcome. Significant differences between those uninfected (n=4,614) and cases infected [≤]4 months ago (n=368) were observed for health utility (OR [95%CI] 1.6 [1.2-2.2]), physical health (OR [95%CI] 1.7 [1.3-2.3]) and fatigue (OR [95%CI] 1.6 [1.2-2.0]), but not for mental health. There were no significant differences between uninfected and cases infected >4 months ago (n=345) for all outcomes. Conclusions: In a Dutch population-based cohort of seroconverted individuals, those infected with wild-type SARS-CoV-2 [≤]4 months ago more often reported poor health utility and physical health and were more often severely fatigued compared to those uninfected (at the 15% cut-off). HRQoL and fatigue remained below the detection limit for those infected >4 months ago, suggesting a relatively low prevalence of PCC.
