The study cohort included all individuals aged 15 years or older, living in Denmark at least one day during 2002\u20132021 (born 1984\u20132006). First psychiatric diagnosis was used to define psychiatric disorder and first homeless shelter contact to define homelessness.

People with any psychiatric disorder had increased risk of sheltered homelessness relative to individuals with no psychiatric disorder [IRR 9.2, 95% confidence interval (CI) 8.8\u20139.6]. Ten years after first psychiatric disorder, 3.0% (95% CI 2.9\u20133.1) had at least one homeless shelter contact. Individuals experiencing homelessness had increased risk of any psychiatric disorder compared to individuals with no homeless shelter contact (IRR 7.0, 95% CI 6.7\u20137.4).
