What is the Prevalence of Low Health Literacy in European Union Member States? A Systematic Review and Meta-analysis

Abstract

Background Many studies have shown that low health literacy (HL) is associated with several adverse outcomes. In this study, we systematically reviewed the prevalence of low HL in Europe. Methods PubMed, Embase, and Scopus were searched. Cross-sectional studies conducted in the European Union (EU), published from 2000, investigating the prevalence of low HL in adults using a reliable tool, were included. Quality was assessed with the Newcastle-Ottawa Scale. Inverse-variance random effects methods were used to produce pooled prevalence estimates. A meta-regression analysis was performed to assess the association between low HL and the characteristics of the studies. Results The pooled prevalence of low HL ranged from of 27% (95% CI: 18–38%) to 48% (95% CI: 41–55%), depending on the literacy assessment method applied. Southern, Western, and Eastern EU countries had lower HL compared to northern Europe (β: 0.87, 95% CI: 0.40–1.35; β: 0.59, 95% CI: 0.25–0.93; and β: 0.72, 95% CI: 0.06–1.37, respectively). The assessment method significantly influenced the pooled estimate: compared to word recognition items, using self-reported comprehensions items (β: 0.61, 95% CI: 0.15–1.08), reading or numeracy comprehensions items (β: 0.77, 95% CI: 0.24–1.31), or a mixed method (β: 0.66, 95% CI: 0.01–1.33) found higher rates of low HL. Refugees had the lowest HL (β: 1.59, 95% CI: 0.26–2.92). Finally, lower quality studies reported higher rates of low HL (β: 0.56, 95% CI: 0.06–1.07). Discussion We found that low HL is a public health challenge throughout Europe, where one in every three to almost one in every two Europeans may not be able to understand essential health-related material. Additional research is needed to investigate the underlying causes and to develop remedies. PROSPERO Registration CRD42019133377

Association between health literacy, general psychological factors, and adherence to medical treatment among Danes aged 50–80 years

“…Self-management strategies, such as taking medications, for successful prevention and management of chronic diseases often require skills to look for and understand essential health information and interact with healthcare professionals [ 2 ]. Low HL levels in this regard is a common challenge shared by many patients globally [ 3 ]. In Europe, on average, 1 in 2 individuals cannot understand essential health information, while slightly lower rates of inadequate HL have been noted in the countries to the north, including Denmark, with around 1 in 5 individuals lacking the ability to understand essential health information [ 3 , 4 ].…”

“…In the last two decades, the number of studies on predictors of HL has increased tremendously, with the majority reporting the association of low HL with poor socioeconomic conditions (e.g., poor educational attainment) as well as poorer health outcomes [ 1 , 3 , 5 – 7 ]. In Denmark, several studies have investigated the association of low HL mainly with poorer health outcomes, e.g.…”

Implementing Public Health Strategies—The Need for Educational Initiatives: A Systematic Review

“…Previous studies in different parts of the world have shown that low or limited health literacy in the US, Southeast Asia, and the European Union are prevalent and consistently associated with several factors such as education, ethnicity, and age. In Europe, one in every two Europeans may not be able to comprehend essential health-related information and materials [72][73][74][75].…”

Association between health literacy and risk of depressive symptoms among Chinese college students

“…A abundant of studies indicated that health literacy level vary greatly in epidemiological investigation among different countries and population, and compared with developed countries from Europe and America, Asian population have a higher proportion of low health literacy. For example, Recent metaanalysis including European Union Member States showed that low health literacy account for 27-48% among European [2]. Similarly, nding from American population-based meta-analysis reported that the prevalence of low health literacy was 26% [3].…”
