Work ability and associated factors among individuals with Post COVID-19 condition- a cross-sectional study

PURPOSE: Long-standing symptoms have been reported after COVID-19 infection, which can negatively impact daily life and work. The purpose of this study was therefore to describe work ability and explore factors associated with poor work ability among individuals with Post COVID-19 Condition (PCC). METHODS: We did an online survey among individuals with self-reported PCC. Descriptive statistics and multivariate logistic regression analysis were used to explore relationships between different factors associated with poor work ability. RESULTS: A total of 608 individuals answered the survey (mean age 47.3 years (SD 9.9), 87% women). The majority (85%) had not been hospitalized on account of a COVID-19 infection. Work ability was experienced as poor among 51%, but only 18% were on sick leave. In the final logistic regression model of four variables (Nagelkerke R Square 0.538, p < 0.001), mental fatigue was the most important factor for perceived poor work ability (Odds ratio 1.176; CI 95%: 1.123–1.232 p < 0.001, Nagelkerke R Square 0.406). Higher levels of dependency in Activities of Daily Living (ADL), greater physical fatigue, and impaired balance were also associated with self-reported poor work ability. CONCLUSION: Perceived poor work ability is common among people with PCC. Several factors are associated with poor work ability in this population whereof mental fatigue seems to be strongest. Given the complexity of these conditions and the consequences in everyday life, it is crucial to implement individually tailored interventions.
