Health literacy and the role of social support in different age groups: results of a German cross-sectional survey.

BACKGROUND: Scholars demand more focus on context-related factors of health literacy as the management of health information is seen as a social practice. One prominent factor is social support that is expected to be particularly relevant for persons vulnerable for low health literacy. It was shown that health literacy can differ across the life span and especially older people have been demonstrated to be vulnerable for low health literacy. Therefore, health literacy and the relation of social support on health literacy in different age groups should be investigated. METHODS: In a German nationwide survey 2,151 adults were interviewed face-to-face. General comprehensive health literacy was measured with the HLS19-Q47 which differentiates single steps of health information management - access, understand, appraise, and apply. Social support was measured with the Oslo 3 Social Support Scale. Bivariate and multivariate analyses were performed for all respondents and for five age groups. RESULTS: Health literacy is relatively low in all age groups but particularly low among old-old people (76 + years). Also, the youngest adults (18-29 years) have slightly lower health literacy than middle-aged adults. On average, health literacy is higher among people with higher social support but this association varies between age groups. It tends to be quite strong among younger adults (18-45 years) and young-old persons (65-75 years) but is weak among older middle-aged (46-64 years) and old-old persons. The association also differs between steps of information management. It is stronger for accessing and applying information but there are differences in age groups as well. CONCLUSIONS: Social support is a relevant aspect to improve individuals' health literacy and therefore should be addressed in interventions. However, it is necessary to differentiate between age groups. While both young adults and particularly old-old persons are challenged by health information management, young adults can strongly profit from social support whereas it can barely compensate the low health literacy of old-old persons. In addition, different challenges in information management steps in different age groups need to be considered when designing health literacy interventions. Thus, target group specific services and programs are needed.

[Health Literacy of People with Former Soviet Union and Turkish Migration Background in Germany]. / Gesundheitskompetenz von Personen mit ex-sowjetischem und türkischem Migrationshintergrund in Deutschland.

AIM: So far, there are hardly any data on the health literacy of persons with a migration background in Germany. The aim of the article was to analyse the health literacy of this population group - particularly persons who originate in Turkey and the former Soviet Union (FSU). METHODOLOGY: In summer 2020, face-to-face interviews with 525 persons with FSU and 512 persons with Turkish migration background above the age of 18 were carried out across Germany. The interviews were conducted in German, Russian or Turkish. Health literacy was assessed using the internationally developed HLS19-Q47 instrument. Bivariate and multivariate analyses were carried out for each immigration group separately considering demographic, socioeconomic, linguistic and migration-specific variables. RESULTS: Overall, around half of the respondents had low health literacy, with no differences between the immigration groups. In both groups, low educational levels, socioeconomic disadvantages, limited German literacy skills, older age, multiple chronic illnesses and personal experience of immigration were linked with lower health literacy. In multivariate analyses, associations between health literacy and literacy skills, social status, financial deprivation, and chronic illness remained; however, after adjustment, no significant difference persisted by immigration generation. CONCLUSION: While a significant proportion of persons with Turkish or FSU migration background in Germany have difficulty dealing with health information, compared with existing studies, they do not have a lower health literacy than the population without a migration background. People with a migration background are therefore not to be regarded as vulnerable to low health literacy in general. Particularly socioeconomically disadvantaged subgroups display low health literacy. Interventions should therefore target these subgroups specifically and consider their living conditions. In addition, people with low literacy skills and German proficiency have greater difficulties in processing health information. This highlights the need for multilingual information, but also for multimedia materials in plain language. Structural measures are necessary for a health-literate health system and for reducing health inequalities.

[Digital Health Literacy of the Population in Germany: Results of the HLS-GER 2]. / Digitale Gesundheitskompetenz der Bevölkerung in Deutschland: Ergebnisse des HLS-GER 2.

AIM: While the availability and variety of digital information on health offers a range of opportunities, they also pose a number of challenges, because the need for digital health literacy (DHL) is increasing along with the growing range of information possibilities. The aim of this study was to analyze the extent of DHL in the German population, key determinants, and consequences for the use of digital health information resources. METHODOLOGY: The analysis was based on data from the Second Health Literacy Survey Germany (HLS-GER 2), consisting of a representative sample of n=2,151. A questionnaire developed as part of the international comparative study HLS19 was used to measure DHL, its determinants, and the use of digital health information resources. Bivariate and multivariate analyses were conducted. RESULTS: Overall, 75.8% of the population had low DHL. In particular, low literacy skills, older age, a lower level of education and social status were associated with low DHL. Multivariate analysis also indicated a strong association between DHL and general health literacy (HL). Low DHL led to lower use of digital health information resources. CONCLUSION: The results underscore the importance of promoting DHL in the general population and especially among groups with low DHL. Efforts in this area should include general HL, as it is closely related to DHL. Strengthening DHL is also a socially important task in order to increase the still low use of digital health information resources in Germany and, in general, to meet the increasing digitalization of the health care system.

The effect of self-efficacy on health literacy in the German population.

Concerning the determinants of health literacy (HL) mostly socio-demographic or -economic factors have been considered, much less so psychological factors such as self-efficacy. To date, it has mostly been considered to explain the relationship of HL and health outcomes. However, self-efficacy could also be an important determinant for HL. This study therefore examines the effect of self-efficacy on comprehensive HL within the general population in Germany. Data from the German HL Survey (HLS-GER), a cross-sectional, computer-assisted personal interview study among 2000 respondents aged 15+ years in 2014 were used. Self-efficacy was measured using the German version of general self-efficacy short scale (ASKU), comprehensive HL was measured using the German version of the European Health Literacy Survey Questionnaire (HLS-EU-Q47). Correlation and multi-variate linear regression analyses were performed to analyze independent effects of socio-demographic factors-age, gender, social status, educational level and migration background-functional HL and self-efficacy on comprehensive HL. Self-efficacy and comprehensive HL are statistically significantly correlated (Spearman's Rho = 0.405; p < 0.01), respondents with better self-efficacy had better HL scores. Both concepts are significantly associated with most socio-demographic factors and functional HL. Self-efficacy showed the strongest association with HL in the multivariate analyses (model 2: ß =0.310, p < 0.001). The effect size of the other predictors decreased, when adding self-efficacy into the equation, but remained statistically significant. Self-efficacy is a rather strong predictor of comprehensive HL. Future research and measures to improve HL should therefore take self-efficacy adequately into account.

[DNVF Memorandum Health Literacy (Part 2) - Operationalisation and Measuring of Health Literacy from a Health Services Research Perspective]. / DNVF Memorandum Gesundheitskompetenz (Teil II) ­ Operationalisierung und Messung von Gesundheitskompetenz aus Sicht der Versorgungsforschung.

The "DNVF Memorandum Health Literacy (Part 2): Operationalization and Measurement of Health Literacy from the Perspective of Health Services Research" of the German Network for Health Services Research represents the continuation of the memorandum "DNVF Memorandum Health Literacy (Part 1): Background, Subject and Issues in Health Services Research". In addition to the general requirements for the measurement of health literacy, this memorandum also deals with the specific requirements, such as the differentiation of health literacy from related constructs, the differences between performance-based and self-assessment methods, the differences between generic and specific instruments, the use of screening instruments, and the measurement of health literacy in special populations. Furthermore, special considerations about the measurement of digital health literacy, potentials of qualitative and participatory research approaches as well as research ethics in the measurement of health literacy will be elaborated on. A special emphasis is placed on practical relevance for health services researchers. Finally, the authors will give an outlook on challenges and research desiderata in connection with the measurement of health literacy in the context of health services research.

Health literacy in former Soviet Union immigrants in the US: A mixed methods study.

BACKGROUND: People with limited health literacy may have trouble finding, understanding, and using health-related information and services and navigating the healthcare system. PURPOSE: The purpose of this study was to assess the health literacy of immigrants from the former Soviet Union (FSU) using the Health Literacy Survey (HLS19-Q12 in Russian) and explore associated socio-demographic factors. METHOD: This mixed methods study recruited adult immigrants through social networks and social media and included data from online survey and follow-up interviews. Variance in health literacy was explained using multiple linear regression. Qualitative data were analyzed through modified Grounded Theory approach. FINDINGS: Survey respondents (n = 318) were primarily female college-educated FSU immigrants aged 20-74 from 14 of the 15 FSU countries and distributed across 33 US states. Forty percent scored at or below predefined cut-offs for inadequate or problematic health literacy levels. Social status, social support, and English proficiency were significant variables in explaining variance in health literacy scores while controlling for age, gender, and education. Interviews (n = 24) identified eight themes: English proficiency, social support, health insurance, experience with health care, complexity of the US healthcare system, relevant health information, health beliefs/practices, and trust. DISCUSSION: There is a need to distribute health-related information in the native language (e.g., Russian), potentially through social media and immigrants' social networks. Health providers should be aware of the prevalence of inadequate and problematic health literacy among FSU immigrants and consider associated social factors.

[Health Literacy in Germany before and during the COVID-19 Pandemic]. / Gesundheitskompetenz in Deutschland vor und während der Corona-Pandemie.

AIM: The aim of this study was to compare the general and digital health literacy (HL) of the German population before the outbreak of the COVID-19 pandemic and during its persistence and to investigate different changes in population groups. METHODOLOGY: The analyses are based on population representative cross-sectional data collected in 2019/2020 before and 2020 during the pandemic. An internationally coordinated questionnaire (HLS19) was used. Changes in groups were analyzed bivariate. RESULTS: The results showed that the HL of the population in Germany tended to improve during the pandemic. This effect was especially evident with regard to the evaluation of health information and in the area of digital HL. Women, people with low or medium education, younger people and those with a migration background appeared to have benefited to a more than average extent. For older people, there was no change, and for those with multiple chronic conditions, the results even indicated a worsening. CONCLUSION: The systematic exposure to clearly structured and continuously repeated health information during the COVID-19 pandemic seems to have improved the ability to process health-related information in the German population. In particular, there has been an increase in competence in dealing with digital information media, which are being increasingly used to communicate health information. However, there are some large differences between different population groups.

Breast cancer incidence and mammography screening among resettlers in Germany.

BACKGROUND: European studies showed that women with a migration background are less likely to participate in mammography screenings than autochthonous women. However, the participation in the German mammography screening programme (MSP) among ethnic German migrants from countries of the former Soviet Union (called resettlers) is unclear so far. The aim of this study was to identify possible differences regarding MSP participation between resettlers from the FSU and the general German population. METHODS: Data from two independent, complementary studies from North Rhine-Westphalia, Germany (a retrospective cohort study 1994-2013; a cross-sectional study 2013/14) were used for comparisons between resettlers and the general population: Odds Ratios (ORs) for MSP participation utilizing the cross-sectional data and time trends of breast cancer incidence rates as well as Chi-Square tests for breast cancer stages utilizing the cohort data. RESULTS: Resettlers showed higher Odds to participate in the MSP than the general population (OR 2.42, 95% CI 1.08-5.42). Among resettlers, a large increase in incidence rates was observed during the MSP implementation (2005-2009), resulting in stable and comparable incidence rates after the implementation. Furthermore, pre-MSP implementation, the proportion of advanced breast cancer stages was higher among resettlers than in the German population, post-MSP implementation the proportion was comparable. CONCLUSIONS: MSP participating seems surprisingly high among resettlers. An explanation for the increased willingness to participate might be the structured invitation procedure of the MSP. However, the exact reasons remain unclear and future research is needed to confirm this hypothesis and rule out the possibility of selection bias in the cross-sectional study.

[Health Literacy among People with Chronic Illness]. / Gesundheitskompetenz von Menschen mit chronischer Erkrankung in Deutschland.

BACKGROUND: People with chronic illnesses (Pwci) face a variety of challenges in managing their illness and using health care. Thus, their need for information and health literacy (HL) is high. While the topic has already been addressed in international research, there is a lack of studies on health literacy among Pwci in Germany. OBJECTIVES AND METHODS: The aim was to analyze HL among Pwci in Germany in more detail. For this purpose, cross-sectional data from a total of 499 Pwci of the German Health Literacy Survey (HLS-GER) were used. HL was assessed with the European Health Literacy Survey Questionnaire (HLS-EU-Q 47). Possible differences in the distribution of low HL by socio-demographic characteristics (gender, age, social status, financial resources, educational level and functional HL (assessed with the Newest Vital Sign (NVS)) and disease-related characteristics (number of diseases and disease duration) were tested using chi-square tests. To investigate the influence of these factors on low HL among Pwci, a multiple logistic regression was performed. RESULTS: Low HL was found in 72.7% of Pwci. Low HL differed greatly according the single domains healthcare, prevention and health promotion. Low social status (OR: 4.4 [1.8; 10.7]), low financial resources (OR: 2.0 [1.2; 3.1]), limited literacy skills (OR: 2.7 [1.4; 5.0]), and an intermediate-level of education (OR: 0.5 [0.3; 0.9]) were associated with low HL in multiple logistic regression. Number and duration of chronic illnesses were not significantly associated with low HL. CONCLUSION: The analysis provides initial findings for Germany that need further investigation. However, they already provide important indications for intervention development. It is necessary to develop target group-specific interventions for strengthening personal health literacy of Pwci, specifically addressing people with low social status, low financial resources and limited literacy. To avoid stigmatization, it is also important to address the information demands in the personal environment. Interventions should make it easier to search for, acquire and process information and thus contribute to reducing inequality.

[Health Literacy in Advanced Age]. / Gesundheitskompetenz im höheren Lebensalter.

BACKGROUND: Health literacy is a frequently discussed concept. Previous studies indicate that older people more often experience difficulties in dealing with health-relevant information compared to the general population. However, existing studies consider older people as a homogeneous group. Therefore, there is a research gap on assessment of health literacy among different subpopulations of older adults. OBJECTIVES AND METHODS: The aim of the study is to make a detailed assessment of health literacy in old age. For this purpose, we conducted an age-specific analysis of HLS-GER study data using descriptive analytic procedures. Analysis of variance (ANOVA) was used to assess the association between mean health literacy scores and age. RESULTS: A large proportion of the older population from the HLS-GER sample of 475 persons aged 65 and older has limited health literacy. Perceived difficulties arise in particular in the domains health care as well as in finding and assessing health information. The results also show statistically significant differences between the age groups. Especially those aged 76 and above have a significantly lower level of health literacy in all domains and dimensions than younger older people. CONCLUSION: These results underline the need for more age-differentiated health literacy research. Additionally, more attention needs to be given to age differentiation in the development of interventions as well.

Health literacy in old age: results of a German cross-sectional study.

Health literacy is especially important for older people to maintain or enhance remaining health resources and self-management skills. The aim of the study was to determine the level of health literacy and the association between health literacy, demographic and socio-economic factors in German older adults aged 65 years and above stratified by age group. Health literacy was assessed via computer-assisted personal interviews using HLS-EU-Q47 on a representative sample of the German-speaking population. Descriptive statistics, bivariate analyses and logistic regression modelling stratified by age group were conducted to assess health literacy of 475 respondents aged 65 years and above. Overall, 66.3% of all respondents aged 65 years and above had limited health literacy. Limited health literacy was especially prevalent among respondents above 76 years of age (80.6%). Limited health literacy was associated with financial deprivation (OR: 3.05; 95% CI: 1.99-4.67) and limited functional health literacy (OR: 2.16; 95% CI: 1.29-3.61). Financial deprivation was strongest predictor for limited health literacy in the total sample and stratified by age group. Limited health literacy is a frequent phenomenon in German adults aged 65 years and above. Research on health literacy in old age and the role in health disparities is urgently needed.

Health literacy among different age groups in Germany: results of a cross-sectional survey.

BACKGROUND: Health 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. METHODS: The 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. RESULTS: The 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. CONCLUSIONS: The 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.

Participation in breast cancer screening among women of Turkish origin in Germany - a register-based study.

BACKGROUND: Population-based breast cancer screening programs were implemented to reduce breast cancer mortality and to improve recovery chances. Breast cancer screening participation among migrant women differs from that of autochthonous populations in several European countries. Here we investigate for the first time participation among women of Turkish origin in Germany. METHODS: Data of five screening units covering 2010 and 2011 as well as associated population registries were analysed. Women of Turkish origin were identified using a name-based algorithm. Participation ratios among women of Turkish origin and odds ratios compared to women of non-Turkish origin were calculated. Analyses were stratified and adjusted for age-groups and screening unit. RESULTS: A total of 208,500 participants in the five breast screening units were included, out of 423,649 eligible women in the catchment areas (participation 49.2%). Women of Turkish origin have a slightly higher chance to participate in breast cancer screening than women without Turkish origin (OR 1.17; 95% CI: 1.14-1.21). Only women of Turkish origin aged 65-69 years have a lower chance to participate than women without Turkish origin (OR: 0.71; 95% CI: 0.66-0.75). CONCLUSION: In spite of low participation in preventive measures among migrant populations, the overall breast cancer screening participation among women of Turkish origin in Germany seems to be higher compared to women of non-Turkish origin. Turkish women aged 65 years and above have a lower chance of participation than younger Turkish women. There is need for further research to study factors affecting participation in screening among migrant and non-migrant populations in Germany.

Navigational health literacy among people with chronic illness.

OBJECTIVES: People with chronic illness are particularly dependent on navigating and using the health care system. This requires navigational health literacy (HL-NAV). The article aims to examine the distribution and predictors of HL-NAV in a sample of chronically ill individuals. METHODS: Data of 1,105 people with chronic illness from the general population in Germany were collected in December 2019 and January 2020. HL-NAV was assessed by 12 items (score 0-100). Bivariate and multiple linear regression analysis were performed. RESULTS: HL-NAV score was 39.1 (SD 27.3). In bivariate analyses, HL-NAV was lower among chronically ill persons aged 65 or above, with low education, limited functional health literacy, low social status, financial deprivation, poor social support, multiple chronic conditions, and an illness duration of 6-10 years. In multivariate analyses, advanced age, lower education, less functional health literacy, lower social status, and less social support remained associated with lower HL-NAV. DISCUSSION: The results underline the importance of promoting HL-NAV among people with chronic illness. Strategies should aim at strengthening individual competencies taking into account the social and situational factors but also at reducing the demands placed on chronically ill people by providing user-friendly and trustworthy information on the health care system along the illness trajectory.

Differences in health literacy domains among migrants and their descendants in Germany.

Background: Health literacy (HL) is considered to be an important precondition for health. HL research often identifies migrants as vulnerable for low HL. However, in-depth data on HL among migrants especially in its domains of health care, disease prevention and health promotion and its determinants are still scarce. Objective: The aim of this study was therefore to analyse the current status of HL among migrants and their descendants from Turkey and from the former Soviet Union (FSU) in Germany and factors associated with it. This has not been studied using large-scale data and bilingual interviews. We differentiate between dimensions of HL, namely the domains of health care, disease prevention and health promotion which goes beyond many previous studies. In addition, we explore new mechanisms by testing the explanatory power of self-efficacy and interethnic contacts for migrants' HL. Methods: The study includes 825 first- and second-generation adult migrants from two of the largest immigration groups in Germany, from Turkey and FSU, who were interviewed face-to-face in German, Turkish or Russian in late summer 2020. HL was measured using the HLS19-Q47 instrument. Age, gender, educational level, social status and financial deprivation, chronic illness, health-related literacy skills, self-efficacy, interethnic contacts, migration generation, duration of stay and region of origin were considered as possible determinants. Ordinary least square regressions were estimated. Results: The average general HL score was 65.5. HL in health promotion and disease prevention was lower than in health care. Low financial deprivation, health-related literacy skills, and self-efficacy were positively correlated with each HL domain. Educational level, social status, age, gender, duration of stay and interethnic contacts were positively correlated with HL in some domains. Region of origin was only correlated with the domain of disease prevention until interethnic contact was accounted for. Conclusion: Our study contributes to the existing knowledge by analyzing different domains of HL and testing its correlations with self-efficacy and interethnic contact among migrants. We reveal that migrants cannot generally be considered as vulnerable for low HL, as oftentimes outlined. There is a need for interventions e.g. to enhance the understanding of health information among subgroups with lower HL.

Adaptation of the Health Literacy Survey Questionnaire (HLS19-Q) for Russian-Speaking Populations-International Collaboration across Germany, Israel, Kazakhstan, Russia, and the USA.

The Russian language is the eighth most spoken language in the world. Russian speakers reside in Russia, across the former Soviet Union republics, and comprise one of the largest populations of international migrants. However, little is known about their health literacy (HL) and there is limited research on HL instruments in the Russian language. The purpose of this study was to adapt the Health Literacy Questionnaire (HLS19-Q) developed within the Health Literacy Survey 2019-2021 (HLS19) to the Russian language to study HL in Russian-speaking populations in Germany, Israel, Kazakhstan, Russia, and the USA. The HLS19-Q was translated either from English or from a national language to Russian in four countries first and then critically reviewed by three Russian-speaking experts for consensus. The HLS19 protocol and "team approach" method were used for linguistic and cultural adaptation. The most challenging was the adaptation of HLS19-Q questions to each country's healthcare system while general HL questions were flexible and adaptable to specific contexts across all countries. This study provides recommendations for the linguistic and cultural adaptation of HLS19-Q into different languages and can serve as an example of international collaboration towards this end.

Health Literacy in Germany - Findings of a Representative Follow-up Survey.

BACKGROUND: Studies have shown that the health literacy of the German population is low. The aim of this article is to analyze current developments in health literacy on the basis of recent data. METHODS: The Health Literacy Survey Germany 2 (HLS-GER 2) is a representative quantitative survey of the German-speaking resident population of Germany aged 18 and above. It was carried out in December 2019 and January 2020 by paper- assisted personal oral interview (PAPI). Data on health literacy and socio - demographic characteristics were acquired with an internationally coordinated questionnaire. The instrument for measuring general health literacy consisted of 47 questions that reflect an individual's ability to access, understand, appraise, and apply health-related information. The associations between general health literacy and sociodemographic factors were analyzed using bivariate and multivariate statistical tests. RESULTS: 58.8% of the participants had low health literacy, characterized by rating at least one-third of the questions as "difficult" or "very difficult." Many respondents stated that they had difficulties accessing (48.3%), understanding (47.7%), and applying (53.5%) information, and even more of them (74.7%) reported difficulties appraising information. The correlation coefficients reveal that health literacy is weakly associated with the following variables: age, sex, social status, literacy, level of education, financial deprivation, migration background, and the presence of one or more chronic diseases. CONCLUSION: The findings of the HLS-GER 2 highlight the need for action in pro - moting health literacy in the healthcare system. As the explanation of variance is low, there are presumably other important determinants of health literacy that were not taken into account. Further studies should be performed to investigate societal conditions of supplying health information, for example, or social and personal characteristics.

A Multilingual Integrative Review of Health Literacy in Former Soviet Union, Russian-Speaking Immigrants.

Large diasporas of former Soviet Union (FSU) immigrants are found in the USA, Germany, and Israel. To synthesize evidence, identify limitations, and propose future directions we conducted an integrative review on the health literacy of FSU immigrants, migrants, or refugees in four languages. Following integrative review and PRISMA guidelines, we searched four databases in English and performed supplementary searches in Russian, German, and Hebrew to identify qualitative and quantitative studies on FSU immigrants and health literacy. Six articles met inclusion criteria in English and one in German; the majority were published in the last five years. Only two articles measured health literacy of FSU immigrants, which was lower than the general population. Four articles were about immigrants with a mean age ≥50 years. All articles stressed the value of translated, culturally relevant health information. The health literacy of FSU immigrants is understudied, despite clear needs. Future research should include assessments of FSU immigrants' health literacy and include diverse (e.g., age, gender) yet well-defined populations to determine both barriers and facilitators to their health literacy. This review, an example of a multilingual search, provided a comprehensive understanding of existing literature and is a useful approach for global health literacy research.
