International Understandings of Health Literacy in Childhood and Adolescence—A Qualitative-Explorative Analysis of Global Expert Interviews

The conceptualization and development of critical health literacy in children: a scoping review

The cognitive and social practices associated with critical health literacy, such as critical appraisal of health messages and participation in political processes to address wider determinants of health, are of lifelong benefit. Understanding how and where critical health literacy development can be supported early in the life course may improve health outcomes now and in the future. This scoping review focuses on how critical health literacy in children is conceptualized and the supportive environments available for its development. Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews guidelines are used in reporting. Evidence retrieved was eligible for inclusion if it contained a substantive conceptual or empirical study of critical health literacy in populations aged 7-11 (middle childhood). From the included 18 peer-reviewed and grey literature sources, schools are identified as the setting most associated with the development of critical health literacy in the target age group. However, the action-oriented dimension of critical health literacy is rarely supported in the school setting. The review concludes that further research is needed to clarify how and where to support children to develop critical health literacy in and outside of school settings.

Impact of digital health interventions for adolescents with type 1 diabetes mellitus on health literacy: a systematic review

BACKGROUND

Evidence shows that living with diabetes mellitus type 1 (T1DM) in adolescent age is particularly challenging and difficult to manage. A high level of health literacy is important to prevent and avoid debilitating complications. Despite the increasing prevalence and incidence of T1DM by adolescent and the large use of digital health interventions, little is known about the association between this use and health literacy. This systematic review provides an overview on the impact of digital health interventions for adolescents with type 1 diabetes on health literacy and derive recommendations for further research.

METHODS

Electronic searches were performed in five databases in Medline (Medline, PubMed + via PubMed), The Cochrane Library, EMBASE (via Ovid), Web of Science and PsycINFO from 2011 to 2021. In addition, grey literature searches were conducted in Google Scholar, OAlster and Trip. Relevant studies that have been missed by electronic and hand-searching strategies were searched in the reference lists of all included studies. The review followed PRISMA guidelines. Two researchers independently screened abstracts for initial eligibility and applied the inclusion and exclusion criteria to the relevant full-text articles. Quality was assessed using the tools RoB2 Cochrane, ROBINS I, NOS (Newcastle-Ottawa Scale), CASP (Critical Appraisal Skills Programme) for primary studies and Amstar-2 for secondary studies.

RESULTS

Out of 981 studies, 22 were included in the final review. Most primary studies included in this review were judged as moderate overall risk of bias or with some concerns and most of the secondary studies as critically low quality reviews. Our findings suggest that the interplay of health care providers (HCP) and patients through social media helps the management of the disease. This corroborates Bröder et al.' (2017) dimension of 'communication and interactions' in their concept of health literacy.

CONCLUSIONS

For adolescents with T1DM, social media may be a specific and beneficial intervention for an improved communication and interaction with their HCP. Further research should investigate what specific form of social media suits best for which adolescents.

TRIAL REGISTRATION

The study protocol was registered on the 15th of November 2021 on Prospero (reg. NR: CRD42021282199).

Health Literacy of People with Intellectual Disabilities: How Meaningful Is the Social Context for a Target Group-Oriented Model of Health Literacy?

Health literacy is primarily understood as an individual construct. People with intellectual disabilities still seem to be a "hidden" population in health literacy research. A target-orientated health literacy approach for this population is needed for developing precise and effective interventions that consider social context dimensions. Therefore, the following research question was answered: Which dimensions influence the health literacy of people with intellectual disabilities? A secondary data analysis containing 38 guided interviews with people with mild to moderate intellectual disabilities was conducted. The analysis followed the content analysis by Schreier (2012). Six main dimensions were inductively outlined, which are "interpersonal relationship", "organizations and communities", "healthcare system", "education", "digital interaction spaces", "politics", and "cultural contexts". All these dimensions influence people with intellectual disabilities on an individual level regarding their level of health literacy. The importance of these single dimensions becomes clear, although for now, the link between all these dimensions is not yet considered. In future research, the focus should be on how to develop interventions considering social context dimensions. Furthermore, analyzing the connection between those dimensions seems promising.

The Forgotten Age Phase of Healthy Lifestyle Promotion? A Preliminary Study to Examine the Potential Call for Targeted Physical Activity and Nutrition Education for Older Adolescents

To date, little research on healthy lifestyle promotion has focused on older adolescents (16–18-year-olds), yet this is a key time that habitual healthy lifestyles could be developed. Ninety-three participants (thirty-nine males; fifty-four females) (mean age = 16.9, (SD 0.4) years), from three low socio-economic high schools in England, completed an online questionnaire on their self-reported: (i) daily physical activity (PA), (ii) active transportation, (iii) active leisure time, (iv) food intake and (v) experiences of how healthy lifestyles are promoted specifically to them. Overall, 60% reached the daily PA recommended guidelines. Yet, 92% used a bicycle/walked for a least 10 min continuously as active transport and of these, 86% undertook this at least 5 days per week. Almost half undertook MVPA as active leisure, but 66% still spent ≥ 5 h sedentary. Seventeen percent met recommended nutritional guidelines for health and 90% (n = 80) did not report school as a place that promoted healthy lifestyles. It is recommended as a public health measure and as an educational policy matter that schools implement more targeted PA and healthy eating initiatives for older adolescents that also include the adolescent voice. Further, gaining a deeper insight into male older adolescents’ health literacy is needed.

Developing Indicators to Measure Critical Health Literacy in the Context of Norwegian Lower Secondary Schools

A critical health literacy (CHL) approach is recommended for promoting health in the school context. This construct is complex and includes three interconnected domains: (A) appraisal of critical information, (B) awareness of the social determinants of health (SDH), and (C) collective action to promote health and well-being. In recent literature reviews, no measurement instrument that covers all three domains of CHL in the school-context was found. Our aim was to develop self-reported measurement scales for each domain of CHL. The development process reported in this study was conducted in two stages. In the first stage, an initial item pool was generated based on literature reviews and focus group interviews (N = 15) with adolescents (steps 1–2). In the next steps, items were adjusted and removed based on the feedback from an expert panel and from representatives from the target group (steps 3–5). In stage two, we aimed to reduce the number of items and develop scales for each domain. We then piloted the current draft, which consists of 28 items (N = 114). A sub-sample (N = 10) of the participants were interviewed after they completed the survey to examine the instrument’s face validity. Cronbach’s α was used to assess the internal reliability of the scales; the reliability was promising for scales A (α = 0.83) and C (α = 0.85) but was below the recommended value for scale B (α = 0.61). The model fit indices were promising (TLI_scaleA = 0.97, RSMEA_scaleA = 0.055, TLI_scaleB = 1.05, RMSEA_scaleB = 0.00, TLI_scaleC = 0.95, RMSEA_scaleC = 0.074). The piloted version of scales A and C were positively correlated with subjective health literacy, health-related quality of life, and subjective health; however, we found no such correlations for scale B. The post-survey group interviews led to some adjustments in scales A and B. The revised version of CHLA-Q must be tested using a larger sample; this will enable more robust statistical testing of the properties of the items and the scale.
