Importance: Psychiatric outcomes after COVID have been of high concern during the pandemic; however, studies on a nationwide level are lacking. All outcomes were adjusted for age, sex, parental history of mental illness, Charlson Comorbidity Index, educational level, income, and job status.
Follow-up time was 1. The risk of mental disorders was increased in individuals with positive HRR, 1. Compared with individuals with negative test results, the risk of new-onset mental disorders in SARS-CoVpositive individuals was lower in the group aged 18 to 29 years HRR, 0. A similar pattern was seen regarding psychotropic medication use, with a decreased risk in the group aged 18 to 29 years HRR, 0.
However, when hospitalized, patients with COVID had markedly increased risk compared with the general population, but comparable to risk among patients hospitalized for non-COVID infections.
Future studies should include even longer follow-up time and preferentially include immunological biomarkers to further investigate the impact of infection severity on postinfectious mental disorder sequelae.
