Quantify the incidence of severe long COVID in a large urban community sample and contrast the physical and emotional functioning of persons experiencing long COVID to those of COVID+ individuals without long COVID.
Design:
A longitudinal survey, administered to COVID+ persons at a large academic urban health system during 2020-2021, was data source. Respondents were recontacted in 2023 to ascertain their health and functioning, update their COVID history, and document persistent COVID-related symptoms.
Composite subscales of the SF-36—the physical component summary (PCS) and mental component summary (MCS) were the key outcomes. The PCS and MCS summarize the 8 dimensions measured by the SF-36, a validated instrument assessing physical functioning, mental health, bodily pain, general health, vitality, social functioning, and role limitations due to emotional problems and physical problems.
Results:
Of 15,064 individuals recontacted, 4,526 (30.0%) participated and 441 (9.7%) reported severe long-COVID defined as persistent fatigue/loss of endurance and/or cognitive deficits.
Median age of COVID+ persons who did not develop severe long-COVID was 60 years (IQR=22); 58.6% were female, and 5.2% were Black/African American. Persons with severe, persistent COVID symptoms were younger (median age= 56 years; IQR=23), and more likely to be female (71%) or identify as Black/African American (8.8%).
Persons with severe long-COVID scored significantly lower on all SF-36 subscales compared to COVID+ respondents without severe long-COVID. Specifically, the PCS mean score was 56% lower [mean(SD): 34.7(38.8) vs. 53.5(42.3), respectively] and the MCS was 35% lower then COVID+ persons without persistent symptoms [78.8(34.3) vs. 81.8(32.3), respectively].
Conclusions:
Individuals experiencing persistent fatigue and cognitive deficits following a COVID-19 infection are more likely to report poorer overall health status and increased physical and emotional limitations than COVID+ persons without severe long COVID. This highlights the need for efficacious rehabilitation programs to reduce disease burden for the large number of individuals experiencing disabling symptoms.
