Background: Digital communication technologies are playing an important role in the health communication strategies of governments and public health authorities during the COVID-19 pandemic. The internet and social media have become important sources of health-related information on COVID-19 and on protective behaviors. In addition, the COVID-19 infodemic is spreading faster than the coronavirus itself, which interferes with governmental health-related communication efforts. This jeopardizes national public health containment strategies. Therefore, digital health literacy is a key competence to navigate web-based COVID-19–related information and service environments. Objective: This study aimed to investigate university students’ digital health literacy and web-based information-seeking behaviors during the early stages of the COVID-19 pandemic in Germany. Methods: A cross-sectional study among 14,916 university students aged ≥18 years from 130 universities across all 16 federal states of Germany was conducted using a web-based survey. Along with sociodemographic characteristics (sex, age, subjective social status), the measures included five subscales from the Digital Health Literacy Instrument (DHLI), which was adapted to the specific context of the COVID-19 pandemic. Web-based information-seeking behavior was investigated by examining the web-based sources used by university students and the topics that the students searched for in connection with COVID-19. Data were analyzed using univariate and bivariate analyses. Results: Across digital health literacy dimensions, the greatest difficulties could be found for assessing the reliability of health-related information (5964/14,103, 42.3%) and the ability to determine whether the information was written with a commercial interest (5489/14,097, 38.9%). Moreover, the respondents indicated that they most frequently have problems finding the information they are looking for (4282/14,098, 30.4%). When stratified according to sociodemographic characteristics, significant differences were found, with female university students reporting a lower DHLI for the dimensions of “information searching” and “evaluating reliability.” Search engines, news portals, and websites of public bodies were most often used by the respondents as sources to search for information on COVID-19 and related issues. Female students were found to use social media and health portals more frequently, while male students used Wikipedia and other web-based encyclopedias as well as YouTube more often. The use of social media was associated with a low ability to critically evaluate information, while the opposite was observed for the use of public websites. Conclusions: Although digital health literacy is well developed in university students, a significant proportion of students still face difficulties with certain abilities to evaluate information. There is a need to strengthen the digital health literacy capacities of university students using tailored interventions. Improving the quality of health-related information on the internet is also key.

Background: An infodemic is an overflow of information of varying quality that surges across digital and physical environments during an acute public health event. It leads to confusion, risk-taking, and behaviors that can harm health and lead to erosion of trust in health authorities and public health responses. Owing to the global scale and high stakes of the health emergency, responding to the infodemic related to the pandemic is particularly urgent. Building on diverse research disciplines and expanding the discipline of infodemiology, more evidence-based interventions are needed to design infodemic management interventions and tools and implement them by health emergency responders. Objective: The World Health Organization organized the first global infodemiology conference, entirely online, during June and July 2020, with a follow-up process from August to October 2020, to review current multidisciplinary evidence, interventions, and practices that can be applied to the COVID-19 infodemic response. This resulted in the creation of a public health research agenda for managing infodemics. Methods: As part of the conference, a structured expert judgment synthesis method was used to formulate a public health research agenda. A total of 110 participants represented diverse scientific disciplines from over 35 countries and global public health implementing partners. The conference used a laddered discussion sprint methodology by rotating participant teams, and a managed follow-up process was used to assemble a research agenda based on the discussion and structured expert feedback. This resulted in a five-workstream frame of the research agenda for infodemic management and 166 suggested research questions. The participants then ranked the questions for feasibility and expected public health impact. The expert consensus was summarized in a public health research agenda that included a list of priority research questions. Results: The public health research agenda for infodemic management has five workstreams: (1) measuring and continuously monitoring the impact of infodemics during health emergencies; (2) detecting signals and understanding the spread and risk of infodemics; (3) responding and deploying interventions that mitigate and protect against infodemics and their harmful effects; (4) evaluating infodemic interventions and strengthening the resilience of individuals and communities to infodemics; and (5) promoting the development, adaptation, and application of interventions and toolkits for infodemic management. Each workstream identifies research questions and highlights 49 high priority research questions. Conclusions: Public health authorities need to develop, validate, implement, and adapt tools and interventions for managing infodemics in acute public health events in ways that are appropriate for their countries and contexts. Infodemiology provides a scientific foundation to make this possible. This research agenda proposes a structured framework for targeted investment for the scientific community, policy makers, implementing organizations, and other stakeholders to consider.

Summary: The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a novel virus in the coronavirus family, causing the coronavirus disease (COVID-19). Biomedical vaccines are key but alongside biomedical vaccines, a social vaccine can be similarly useful to prevent infection from SARS-CoV-2, if applied as a health promotion strategy. In order to slow down and control the spread of SARS-CoV-2, applying the social vaccine concept should be considered in parallel. From a health promotion perspective, a social vaccine is a process of social and political mobilization driven by governmental and non-governmental organizations aiming at populations by applying interventions such as health communication, education and mass media campaigns as well as determinant-based programs to address environmental factors influencing personal behavior and community capacities to cope with and overcome the societal burdens of COVID-19. In this context, health literacy is significant, as seen in the role it plays in empowering citizens during the COVID-19 pandemic and enabling them to deal with health information considering COVID-19. As a public health strategy, health literacy as a social vaccine will enable individuals and communities to mitigate the spread of the virus by understanding and applying information as provided through governments and health authorities. The aim of this article is to explore health literacy as a promising social vaccine and opportunity to utilize social vaccination and thus be considered as a key public health approach—both bottom-up and top-down—to support the combat of COVID-19 and future states of emergency.

Early-on in the COVID-19 pandemic when universities were closed as part of the nation-wide public health response to the COVID-19 outbreak, studying and student life significantly changed. Based on limited evidence the aim of this study was to explore the relationship between sense of coherence (SoC), future worries and mental health outcomes among German university students during the early phase of the pandemic. A cross-sectional online survey with n = 14 916 participants was carried out by inviting all private and public universities in Germany. All data were analysed using univariate, bivariate and multivariate statistics. Findings indicate a low and very low wellbeing for 38% of university students. Moreover, 29% reported being affected by at least two health complaints more than once week. Both health outcomes follow a social gradient and could be more frequently observed for respondents with lower subjective social status and female students. Regression analysis revealed significant association between the SoC dimensions and wellbeing (OR: 1.2−2.03) as well as health complaints (OR: 1.58−1.71). A high level of future worries was associated with low/very low wellbeing (OR: 2.83) and multiple health complaints (OR: 2.84). Based on the results, the public health response to the pandemic and university health promotion should therefore consider student mental health as an important target within their policy and action frameworks.

Zusammenfassung: Hintergrund: Die vorliegende Studie untersucht, in welchem Ausmaß Schulen Maßnahmen der Gesundheitsförderung und Prävention während der COVID-19-Pandemie umsetzen. Von besonderem Interesse sind hierbei Unterschiede nach demografischen Variablen, Schulform, Bundesland und die Beteiligung an Landesinitiativen der Gesundheitsförderung. Methodik: Im Rahmen des COVID-Health-Literacy-Netzwerks wurde von März bis April 2021 eine Onlinestudie mit 2186 Schulleitungen in Baden-Württemberg, Hessen, Niedersachsen und Nordrhein-Westfalen durchgeführt. Der Umsetzungsstand der COVID-19-bezogenen schulischen Gesundheitsförderung und Prävention wurde mittels eines eigenentwickelten Instruments untersucht. Nach Analyse der faktoriellen Struktur des Instruments erfolgten uni- und bivariate Auswertungen. Ergebnisse: Es lassen sich 3 Dimensionen des Umsetzungsstandes der schulischen Gesundheitsförderung identifizieren (1. COVID-19-bezogene Unterstützung der Schüler*innen, 2. Gesundheitsförderliche Gestaltung von Lehr‑, Lern- und Arbeitsbedingungen, 3. Prinzipien der Gesundheitsfördernden Schule). Eine geringe Umsetzung liegt für Aspekte der Lehr‑, Lern- und Arbeitsbedingungen sowie für Partizipation und die Kooperation mit schulexternen Akteuren vor. Signifikante Unterschiede des Umsetzungsstands ergeben sich zugunsten von weiblichen und älteren Schulleitungen sowie Grundschulen. Außerdem zeigen sich nicht homogene Unterschiede nach Bundesland. Differenziert nach Teilnahme an einem Landesprogramm findet sich lediglich für Schulen mit Zertifikat im Bereich Gesundheitsförderung ein höherer Umsetzungsstand. Diskussion: Die Ergebnisse geben Hinweise darauf, dass die COVID-19-Pandemie für Schulen ein disruptives Ereignis darstellt, welches die Umsetzung schulischer Gesundheitsförderung erschwert. Vor allem gesundheitsförderliche Arbeitsbedingungen, Partizipation und Kooperation sollten in den Fokus genommen werden.
