Cohort Profile: COVIDMENT: COVID-19 cohorts on mental health across six nations
International Journal of Epidemiology, doi: 10.1093/ije/dyab234
- COVIDMENT (covidment.is) is a NordForsk funded research collaboration across six nations with the overarching aim to significantly advance current knowledge on mental morbidity trajectories associated with the Coronavirus disease 2019 (COVID-19) in the general population and specific risk groups.
- From March 2020 through August 2021, 392 817 individuals have been recruited to the seven COVIDMENT cohorts: The Danish Blood Donor Study (N=71 562), the Estonian Biobank COVID-19 and Mental Health Data Collection cohorts (N=13 329 and N=86 116, respectively), the Icelandic COVID-19 National Resilience Cohort (N=22 849), the Norwegian BRY.DEG2020 (N=19 343), the Norwegian Mother, Father and Child Cohort Study (N=132 486), the Scottish Generation Scotland/CovidLife (N=18 518), and the Swedish Omtanke2020 (N=28 614). Semi-harmonized questionnaire data have been collected across all COVIDMENT cohorts with longitudinal data available, e.g., through linkage to the national registers.
- The average age of participants ranged from 31.8 to 58.5 years across cohorts. The prevalence of depressive symptoms above cut-off point varied considerably across cohorts (4.2-8%). The prevalence of depressive symptoms was highest at COVID-19 incidence of 30 cases per week per 100 000 persons, i.e., 14.3% (95% CI: 9.4-21.8%), which was 61.0% (95% CI: 34.0-94.1%) higher than the prevalence at COVID-19 incidence of 0 cases per week per 100 000 persons (P = 1.1 x 10 ^(-6)).
- We welcome proposals for collaboration; please visit our website covidment.is for further information.
