N2 - Migrants and ethnic minorities are disproportionately affected by the Coronavirus Disease 2019 (COVID-19) pandemic compared to the majority population. Therefore, we studied mortality and use of mechanical ventilation (MV) by country of birth and migrant status in a nationwide cohort in Denmark. Nationwide register data on all cases hospitalized for > 24-hours with COVID-19 between February 2020 and March 2021. Main outcome measures were mortality and MV within 30 days of hospitalization for COVID-19. Odds ratios (OR) and 95% confidence intervals (95% CI) were estimated by region of origin and migrant status using logistic regression analyses, adjusting for age, sex, comorbidity and sociodemographic factors. Of 6,406 patients, 977 (15%) died and 342 (5%) were treated with mechanical ventilation. Immigrants (OR:0.55;95%CI: 0.44–0.70) and individuals of non-Western origin had a lower odds (OR: 0.49; 95% CI: 0.37–0.65) of death upon admission with COVID-19 compared to Danish born individuals. Immigrants and descendants (OR: 1.62; 95% CI: 1.22–2.15) as well as individuals of non-Western origin (OR: 1.83; 95% CI: 1.35–2.47) had a significantly higher odds of MV compared to Danish born individuals. Outcomes of individuals with Western origin did not differ. Immigrants and individuals of non-Western origin had a significantly lower COVID-19 associated mortality compared to individuals of Danish origin after adjustment for sociodemographic factors and comorbidity. In contrast, the odds of MV was higher for immigrants and individuals of non-Western origin compared to individuals of Danish origin.
