[A Continuous Literature Review for Mental Health Surveillance during the Covid-19 Pandemic in Germany - Method, Selected Results and Lessons Learned]. / Kontinuierliches Literaturreview zur Surveillance der psychischen Gesundheit in Deutschland während der COVID-19-Pandemie ­ Methode, ausgewählte Ergebnisse und Lessons Learned.

In order to provide an up-to-date overview on changes in population's mental health during the COVID-19 pandemic, a continuous literature review was conducted. Building on a rapid review, systematic and hand searches were conducted monthly until December 31, 2022. Studies were assessed for observation periods, risk of bias and outcomes. Trends in depressive symptoms in adults were summarized by vote counting. 102 publications were included from 62 studies in the adult population. Studies declined over the course of the pandemic. Overall, 37% of the studies and 56% of the publications can assess trends in the population reliably. Among evidence for changes in depressive symptoms deteriorations predominated at last. The heterogeneity of results published by the end of 2022 limits evidence syntheses. Evidence of deterioration requires further surveillance. A continuous review can indicate evidence gaps at an early stage.

Socioeconomic Differences in SARS-CoV-2 Infection and Vaccination in Germany: A Seroepidemiological Study After One Year of COVID-19 Vaccination Campaign.

Objective: To evaluate the socioeconomic patterns of SARS-CoV-2 antigen contacts through infection, vaccination or both ("hybrid immunity") after 1 year of vaccination campaign. Methods: Data were derived from the German seroepidemiological Corona Monitoring Nationwide study (RKI-SOEP-2; n = 10,448; November 2021-February 2022). Combining serological and self-report data, we estimated adjusted prevalence ratios (PR) of SARS-CoV-2 infection, COVID-19 vaccination, basic immunization (at least two SARS-CoV-2 antigen contacts through vaccination and/or infection), and three antigen contacts by education and income. Results: Low-education groups had 1.35-times (95% CI 1.01-1.82) the risk of SARS-CoV-2 infection compared to high-education groups. COVID-19 vaccination (at least one dose) and basic immunization decreased with lower education and income. Low-education and low-income groups were less likely to have had at least three antigen contacts (PR low vs. high education: 0.74, 95% CI 0.65-0.84; PR low vs. high income: 0.66, 95% CI 0.57-0.77). Conclusion: The results suggest a lower level of protection against severe COVID-19 for individuals from low and medium socioeconomic groups. Pandemic response and vaccination campaigns should address the specific needs and barriers of these groups.
