There is an “infodemic” associated with the COVID-19 pandemic—an overabundance of valid and invalid information. Health literacy is the ability to access, understand, appraise, and apply health information, making it crucial for navigating coronavirus and COVID-19 information environments. A cross-sectional representative study of participants ≥ 16 years in Germany was conducted using an online survey. A coronavirus-related health literacy measure was developed (HLS-COVID-Q22). Internal consistency was very high (α = 0.940; ρ = 0.891) and construct validity suggests a sufficient model fit, making HLS-COVID-Q22 a feasible tool for assessing coronavirus-related health literacy in population surveys. While 49.9% of our sample had sufficient levels of coronavirus-related health literacy, 50.1% had “problematic” (15.2%) or “inadequate” (34.9%) levels. Although the overall level of health literacy is high, a vast number of participants report difficulties dealing with coronavirus and COVID-19 information. The participants felt well informed about coronavirus, but 47.8% reported having difficulties judging whether they could trust media information on COVID-19. Confusion about coronavirus information was significantly higher among those who had lower health literacy. This calls for targeted public information campaigns and promotion of population-based health literacy for better navigation of information environments during the infodemic, identification of disinformation, and decision-making based on reliable and trustworthy information.

BackgroundHealth literacy is of increasing importance in public health research. It is a necessary pre-condition for the involvement in decisions about health and health care and related to health outcomes. Knowledge about limited health literacy in different age groups is crucial to better target public health interventions for subgroups of the population. However, little is known about health literacy in Germany. The study therefore assesses the prevalence of limited health literacy and associated factors among different age groups.MethodsThe Health Literacy Survey Germany is a cross-sectional study with 2,000 participants aged 15 years or older in private households. Perceived health literacy was assessed via computer-assisted personal interviews using the HLS-EU-Q-47 questionnaire. Descriptive analyses, chi-square tests and odds ratios were performed stratified for different age groups.ResultsThe population affected by limited perceived health literacy increases by age. Of the respondents aged 15–29 years, 47.3 % had limited perceived health literacy and 47.2 % of those aged 30–45 years, whereas 55.2 % of the respondents aged 46–64 years and 66.4 % aged 65 years and older showed limited perceived health literacy. In all age groups, limited perceived health literacy was associated with limited functional health literacy, low social status, and a high frequency of doctor visits.ConclusionsThe results suggest a need to further investigate perceived health literacy in all phases of the life-course. Particular attention should be devoted to persons with lower social status, limited functional health literacy and/or a high number of doctor visits in all age groups.

The low health literacy of many Germans can impair communication between doctors and patients and exacerbate existing problems in health policy. In the future, greater effort will have to be made to foster health literacy, make health-related information for patients easier to understand, and intensify research in the field of health literacy.

Zusammenfassung Ziel Durch die Digitalisierung gewinnen digitale Informationen zum Thema Gesundheit zunehmend an Bedeutung. Neben vielfältigen Chancen bringt diese Entwicklung auch Herausforderungen mit sich, denn mit dem wachsenden Angebot steigt zugleich der Bedarf an digitaler Gesundheitskompetenz (DGK). Im nachfolgenden Beitrag werden das Ausmaß der DGK in der Bevölkerung in Deutschland, zentrale Determinanten der DGK und Folgen für die Nutzung digitaler gesundheitsbezogener Informationsangebote analysiert. Methodik Die Analyse basiert auf Daten des zweiten Health Literacy Survey Germany (HLS-GER 2), bestehend aus einer repräsentativen Stichprobe mit n=2151. Die Erfassung der DGK, der Determinanten sowie der Nutzung digitaler gesundheitsbezogener Informationsangebote erfolgte mit einem im Rahmen der internationalen Vergleichsstudie HLS19 erarbeiteten Fragebogens. Es wurden bivariate und multivariate Analysen durchgeführt. Ergebnisse Insgesamt verfügen 75,8% der Bevölkerung über eine geringe DGK. Vor allem geringe literale Fähigkeiten, ein höheres Alter, eine niedrige Bildung sowie ein niedriger Sozialstatus gehen mit einer geringen DGK einher. Die multivariate Analyse weist zudem auf einen starken Zusammenhang zwischen DGK und allgemeiner Gesundheitskompetenz (GK) hin. Geringe DGK ist folgenreich und führt zu einer geringeren Nutzung digitaler gesundheitsbezogener Informationsangebote. Schlussfolgerung Die Ergebnisse unterstreichen die Wichtigkeit der Förderung von DGK der Bevölkerung und besonders von Gruppen mit geringer DGK. Entsprechende Bemühungen sollten die allgemeine GK einbeziehen, denn sie steht in engem Zusammenhang mit der DGK. Auch um die noch geringe Nutzung digitaler Informationsangebote in Deutschland zu erhöhen und generell, um der zunehmenden Digitalisierung des Gesundheitswesens zu entsprechen, stellt die Stärkung der DGK eine gesellschaftlich wichtige Aufgabe dar.
