Abstract

Abstract: Funding Acknowledgements: Type of funding sources: Foundation. Main funding source(s): Dutch Heart Foundation Background: More than 250 million cases of the coronavirus disease-2019 (COVID-19) infection were confirmed across the globe since 2020, leading to a substantial number of COVID-19 related hospital admissions. Many COVID-19 survivors experience long-term health consequences, but data on physical activity patterns and the impact on recovery post-infection are scarce. Purpose: This study aimed to objectively assess physical (in)activity patterns among COVID-19 survivors and to explore the association with patient characteristics, disease severity and cardiac dysfunction. We hypothesized that COVID-19 survivors will demonstrate low volumes of physical activity and a high sedentary time, especially those with a more severe disease course (e.g. longer hospital duration; admission to intensive care), cardiac dysfunction, and persistent symptoms at 3-6 months post-discharge. Methods: In this cross-sectional cohort study, we objectively assessed physical activity, sedentary behaviour and sleep duration for 24 hrs/day during 8 subsequent days in COVID-19 survivors at 3-6 months post-hospitalisation. Activity patterns were compared across pre-defined subgroups based on patient- and disease characteristics, cardiac biomarker release during hospitalisation, abnormal transthoracic echocardiogram regarding left- and right ventricular function and volumes at 3-6 months of follow-up, and persistence of symptoms post-discharge. Results: Physical activity patterns were assessed in 37 patients (60±10 years old; 78% male) at 125 [116; 132] days after discharge. Patients spent 4.2 [3.2; 5.3] hrs/day in light-intensity physical activity and 1.0 [0.8; 1.4] hrs/day in moderate-to-vigorous intensity physical activity. Median sleep duration was 8.6 [8.2; 9.1] hrs/day. Time spent sitting was 9.8 [8.7; 11.2] hrs/day, which was accumulated in 6.0 [4.7; 6.9] prolonged sitting bouts (≥30 min) and 41.4 [31.5; 48.1] short sitting bouts (<30 min, Central Figure). No differences in activity patterns were found across subgroups, but sleep duration was slightly higher in women versus men (9.2 vs 8.5 hrs/day, p=0.03) and patients with versus without persistent symptoms (9.1 vs 8.3 hrs/day, p=0.02). Conclusions: COVID-19 survivors are physically inactive for most of their time at 3-6 months post-hospitalisation. Physical (in)activity patterns are not impacted by patient- nor disease characteristics, underlining the need for a uniform approach for re-activation of COVID-19 survivors. Central Figure.
