Subjective Generic Health Literacy and Its Associated Factors among Adolescents: Results of a Population-Based Online Survey in Germany.

ABSTRACT: Profound data on adolescent health literacy are needed as a requirement for the development of health literacy promoting interventions. This paper aims to study the level of generic health literacy among adolescents and to explore associations between health literacy and socio-demographic (age, sex, family affluence, migration background), social (social support by family and friends) and personal (self-efficacy) factors. We conducted a representative cross-sectional online survey. Four health literacy dimensions were captured among 14-17 years old adolescents living in Germany (n = 1235) with the "Measurement of Health Literacy Among Adolescents-Questionnaire" (MOHLAA-Q). Descriptive, bivariate and multiple logistic regression analyses were used to analyse the data (n = 1202). We found poor health literacy levels-to varying degrees-in all examined health literacy dimensions: dealing with health-related information (8.41% with many difficulties), health-related communication skills (28.13% with low skills), attitudes toward one's own health and health information (8.81% with passive attitudes) and health-related knowledge (22.73% with low levels). We identified significant associations between poor health literacy levels and all factors studied except for age. Our results indicate a need for the implementation of evidence-based health literacy-related promoting interventions, preferentially in education and training institutions.

Project description:Purpose. There is no gold-standard health literacy measure. The Single Item Literacy Screener (SILS) and Subjective Literacy Screener (SLS) ask people to self-report ability to understand health information. They were developed in older adults, before common use of electronic health information. This study explored whether the SILS and SLS related to objective literacy, numeracy, and comprehension among young adults, and whether specifying "online" or "paper-based" wording affected these relationships. Methods. Eligible individuals (18-35 years of age, English-speaking, US residents) from an online survey company were randomized to 1) original measures; 2) measures adding "paper-based" to describe health information/forms; or 3) measures adding "online" to describe health information/forms. We examined how each measure related to e-Health Literacy (eHEALS), subjective numeracy (SNS), objective numeracy (ONS), and comprehension of a short passage. Results. A total of 848/1342 respondents correctly answered attention-checks and were analyzed. The validated SILS related to comprehension (P = 0.003), eHEALS (P = 0.04), and ONS (P < 0.001) but not SNS (P = 0.44). When adding "paper-based," SILS related to eHEALS (P < 0.001) and ONS (P = 0.003) but did not relate to comprehension (P = 0.25) or SNS (P = 0.35). When adding "online," SILS related to comprehension (P < 0.001), eHEALS (P < 0.001), ONS (P = 0.005), and SNS (P = 0.03). The validated SLS related to comprehension (P < 0.001), eHEALS (P < 0.001), ONS (P < 0.001), and SNS (P < 0.001). When adding "paper-based," the SLS only related to eHEALS (P = <0.001) and comprehension (P = 0.03) but did not relate to ONS (P = 0.13) or SNS (P = 0.33). When adding "online," the SLS related to comprehension (P < 0.001), eHEALS (P < 0.001), and SNS (P = 0.03) but not ONS (P = 0.06). Conclusions. Young adults might interpret subjective health literacy measures differently when prompted to think about electronic or paper-based information. Researchers should consider clearer instructions or modified wording when using these measures in this population.

Project description:IntroductionChildhood vaccination against hepatitis B has been recommended in Germany since 1995. WHO defines a primary vaccination series as successful if the initial hepatitis B surface antibody (anti-HBs) level is ≥ 10 IU/L directly after vaccination. Anti-HBs levels vary depending on the number of doses, type of vaccine, and time interval between the last two doses. In 2021, Germany began to recommend three instead of four doses of polyvalent hepatitis-B-containing vaccines. Our aim was to estimate the proportion of vaccinated children in Germany with anti-HBs levels < 10 IU/L, 10-99 IU/L, and ≥ 100 IU/L by number and type of vaccine, and assess if number of doses and compliance with recommended time interval between the last two doses are associated with an anti-HBs level ≥ 10 IU/L when considering type of vaccine and time since last dose.MethodsWe used data from a national cross-sectional study (2014-2017) of children (3-17 years). We excluded participants with unknown vaccination dates, unreadable or incomplete vaccination cards, and hepatitis B virus (HBV)-positive participants. We defined a recommended schedule as a vaccination series with at least six months between the two last doses and having three doses or more. We calculated weighted anti-HBs sero-prevalence for three anti-HBs levels: < 10 IU/L, 10-99 IU/L and ≥ 100 IU/L. We fitted two logistic regression models to examine the relationship between number of doses and recommended schedule on anti-HBs levels (≥ 10 IU/L and ≥ 100 IU/L) considering time since last dose and type of vaccine (Infanrix, Hexavac, Monovalent).ResultsWe included 2,489 participants. The weighted proportion of vaccinated children per anti-HBs level was < 10 IU/L: 36.3% [95%CI 34.0-38.7%], 10-99 IU/L: 35.7% [33.2-38.2%] and ≥ 100 IU/L: 28.0% [25.9-30.2%]. We did not find an association between a recommended schedule of three versus four doses and anti-HBs ≥ 10 IU/L or ≥ 100 IU/L.ConclusionsAnti-HBs levels in later childhood were about equal, whether children received three or four doses. This implies that the change in the recommendations does not affect the anti-HBs level among children in Germany. Future studies are needed on the association of anti-HBs levels and adequate sustained protection against HBV.

Project description:In Germany, there are no measurement tools to assess the general health literacy of adolescents. The aim of the study "Measurement of Health Literacy Among Adolescents" (MOHLAA) is to develop such a tool for use among adolescents aged 14-17. The German version of the European Health Literacy Survey Questionnaire (HLS-EU-Q47-GER) served as a blueprint for the development of the tool. The present study examined the extent to which the HLS-EU-Q47-GER can be applied to the measurement of general health literacy in adolescents.The applicability of the HLS-EU-Q47-GER for adolescents was tested qualitatively using cognitive interviewing (CI). Purposive sampling was used to achieve an equal distribution of participants regarding age groups, educational backgrounds and gender. CI was standardized on the basis of an interview guide. Verbal probing and the retrospective think-aloud technique were applied. The interviews were audio-recorded, transcribed and analyzed using the criteria of theory-based analysis, which were derived from the model of cognitive processes. The analysis focused on identifying terms and questions that were difficult to understand and on scrutinizing the extent to which the content of the items is appropriate for assessing adolescents' health literacy.Adolescent respondents were unfamiliar with some terms of the HLS-EU-Q47-GER or provided heterogeneous interpretations of the terms. They had limited or no experience regarding some health-related tasks in health care and disease prevention that are addressed by HLS-EU-Q-items. A few items seemed to be too "difficult" to answer due to a high abstraction level or because they lacked any reference to the everyday lives of youth. Despite comprehension problems with some of the HLS-EU items, the respondents assessed the covered health-related tasks as "very easy" or "fairly easy". CI stressed the importance of interpersonal agents, especially parents, in helping adolescents understand and judge the reliability of health information.The results of CI indicated that the applicability of the HLS-EU-Q47-GER to the measurement of general health literacy among adolescents aged 14-17 is limited. In order to prevent biased data, some items of the questionnaire should be adjusted to adolescents' state of development and experiences with health care and disease prevention.
