Long COVID Is Associated with Decreased Quality of Life and Increased Mental Disability

Abstract

COVID-19’s impact on quality of life (QoL) has been studied; however, data on the effects of long COVID on QoL and mental disability remain limited. This study aimed to investigate whether long COVID is associated with decreased QoL and increased mental disability. We analyzed data from adults (≥18 years) in the 2022 Medical Expenditure Panel Survey (MEPS). Physical and mental QoL were assessed using the Veterans RAND 12-Item Health Survey, while mental disability was measured with the Kessler Index. Long COVID was defined as experiencing COVID-related symptoms for over 3 months. To account for skewness in the outcome variables, the study employed survey-weighted generalized linear regression with a log link and gamma distribution. The analysis included 153,330,408 subjects (unweighted n = 10,975). The average age of those with and without long COVID was similar (51 vs. 52 years, p = 0.46). Subjects with long COVID had a 3% lower physical QoL (β = −0.03, p = 0.02), a 4% lower mental QoL (β = −0.04, p < 0.01), and a 26% higher mental disability score (β = 0.26, p < 0.01) compared to those without long COVID. These findings highlight the urgent need for targeted strategies to address long COVID and support patients in recovering their pre-COVID QoL and mental health.
