Post-COVID-19 conditions in children and adolescents diagnosed with COVID-19

Background- This study aimed to investigate the prevalence of and the factors associated with post-COVID-2019 condition in COVID-19 children and adolescents in Germany. Methods- The present retrospective cohort study used data from the Disease Analyzer database (IQVIA), and included patients aged <18 years who were diagnosed with COVID-19 in one of 524 general and 81 pediatric practices in Germany between October 2020 and August 2021 (index date: first COVID-19 diagnosis). Post-COVID-19 condition was assessed between the index date and November 2021. Covariates included age, sex, type of practice, and chronic conditions documented in at least 1% of the population. Results- There were 6568 children and adolescents included in this study (mean [SD] age 10.1 [4.9] years; 49.2% girls). The prevalence of post-COVID-19 condition was 1.7% in the population. Patients aged 13–17 years were more likely to be diagnosed with post-COVID-19 condition compared with those being aged ≤5 years (RR = 3.14). Anxiety disorders (RR = 2.53), somatoform disorders (RR = 2.11), and allergic rhinitis (RR = 2.02) were also significantly associated with post-COVID-19 condition. Conclusion- Post-COVID-19 condition was rare in COVID-19 children and adolescents in Germany. Data from other settings are warranted to confirm these findings.
