Health Literacy among Older Adults in Portugal and Associated Sociodemographic, Health and Healthcare-Related Factors

Although the health literacy level of the general population was described recently, little is known about its specific levels among older adults in Portugal. Therefore, this cross-sectional study aimed to investigate the levels of health literacy demonstrated by older adults in Portugal and explore associated factors. Using a randomly generated list of telephone numbers, adults aged 65 years or more living in mainland Portugal were contacted in September and October 2022. Sociodemographic, health and healthcare-related variables were collected, and the 12-item version of the European Health Literacy Survey Project 2019-2021 was used to measure health literacy. Then, binary logistic regression models were used to investigate factors associated with limited general health literacy. In total, 613 participants were surveyed. The mean level of general health literacy was (59.15 ± 13.05; n = 563), whereas health promotion (65.82 ± 13.19; n = 568) and appraising health information (65.16 ± 13.26; n = 517) were the highest scores in the health literacy domain and the dimension of health information processing, respectively. Overall, 80.6% of respondents revealed limited general health literacy, which was positively associated with living in a difficult household financial situation (4.17; 95% Confidence Interval (CI): 1.64-10.57), perceiving one's own health status as poorer (7.12; 95% CI: 2.02-25.09), and having a fair opinion about a recent interaction with primary healthcare services (2.75; 95% CI: 1.46-5.19). The proportion of older adults with limited general health literacy in Portugal is significant. This result should be considered to inform health planning according to the health literacy gap of older adults in Portugal.

A Systematic Review of Health Literacy Measurement Instruments in Portugal

<b><i>Introduction:</i></b> Health literacy evaluation is considered a priority issue in the health literacy research field. The complexity of the multiple definitions of health literacy and the diversity of instruments to evaluate health literacy has become a challenge to the establishment of comparisons across different studies. This work aimed to provide a systematic literature review of the existing measurement instruments adapted or developed for different groups of the Portuguese population. <b><i>Methods:</i></b> A comprehensive search of digital databases was conducted to systematize and understand the available knowledge about health literacy measurement in Portugal and to identify assessment tools and studies developed. The selection process was based on PRISMA guidelines. <b><i>Results:</i></b> A total of 17 publications were analysed regarding different aspects, which resulted in the identification of 11 different instruments, that were adapted or developed to measure health literacy in different groups of the Portuguese population, mainly adults, adolescents, and young adults. Seven instruments focusing on general health literacy (including e-health), 2 on mental health literacy, and the other 2 on oral health literacy were identified. <b><i>Discussion/Conclusion:</i></b> This study presents the first general overview of health literacy measurement in Portugal and clearly shows that to deepen our knowledge of health literacy in the Portuguese population it is essential to broaden the scope and the target of health literacy assessment to have a comprehensive understanding that will allow transforming our reality regarding health and disease.

Informal Caregivers' Health Literacy in Lisbon, Portugal: A Profile for Health Promotion Prioritization

Health literacy (HL) allows people to access, understand and evaluate health information. Informal caregivers’ levels of HL may impact long-term care outcomes. ‘Informal caregivers’ profile in Lisbon county: a health community approach’ is a nurse-led research project aiming to assess informal caregivers’ health literacy and associated factors in Lisbon county, as well as to foster the development of a local-specific health literacy strategy. A survey to identify a health/social caregiver profile, including questions about HL (HLS-EU-PT), was submitted to a representative sample of carers. Descriptive and bivariate inferential analysis was developed. Informal caregivers’ level of HL was mostly sufficient (n = 99, 38%). More than 60% of caregivers have limited HL regarding health promotion. ‘Access’, ‘Appraisal’ and ‘Use’ are the information processing stages with lower mean scores of HL. Carers with low HL levels appear to be older and to have less education, low knowledge of community resources and decreased wellbeing (p < 0.05). A strategy focused on health promotion-related HL through primary care resources can potentially improve caregivers’ knowledge, competencies and motivation, as well as health system sustainability. Reported HLS-EU-PT scores deserve special attention. Future work should emphasize the role of HL-associated factors and health outcomes for caregivers and cared-for persons.

National Action Plan Health Literacy in Germany origin, development and structure

Aim

Health literacy has gained increasing importance worldwide. As a result of several studies indicating low health literacy levels in large parts of the population, strategies and action plans promoting health literacy were developed in many countries. The article analyses the origin, development and structure of the German Health Literacy Action Plan.

Subject and methods

In 2016, a civil society initiative was formed, aiming at developing a national action plan in an expert-based and collaborative manner. A group of 15 experts elaborated the core elements of the action plan, based on a literature review on existing health literacy approaches, action plans and empirical evidence. These core elements were further developed collaboratively in workshops with key stakeholders, self-help and patient organizations and individual consultation meetings. Afterwards, the National Action Plan was reviewed and previously formulated recommendations were refined before being published.

Results and conclusion

The National Action Plan Health Literacy in Germany presents 15 recommendations in four areas of action for promoting health literacy in Germany. This bottom-up strategy and the expert-based yet at the same time collaborative approach have proved to be successful when developing a national action plan.

Digital Health Intervention to Increase Health Knowledge Related to Diseases of High Public Health Concern in Iringa, Tanzania: Protocol for a Mixed Methods Study

BACKGROUND

Traditionally, health promotion and health education have been provided to communities in the global south in the form of leaflets or orally by health care workers. Digital health interventions (DHIs) such as digital health messages accessed by smartphones have the potential to reach more people at a lower cost and to contribute to strengthening of health care systems. The DHI in this study focuses on disseminating digital health education regarding 3 disease complexes of high public health concern: HIV/AIDS, tuberculosis, and Taenia solium (neuro)cysticercosis or taeniasis, a parasitic zoonotic disease that requires a One Health approach. The DHI presents the participants with animated health videos (animations) and provides access to information spots (InfoSpots) with a free-of-charge digital health platform containing messages about health to rural Tanzanian communities.

OBJECTIVE

The objective of this study is to measure the effect of the DHI on health knowledge uptake and retention over time in the rural communities.

METHODS

This is a mixed methods study including a nonrandomized controlled trial and qualitative interviews conducted in rural Tanzania. A health platform containing digital health messages for the communities was developed prior to the study. The health messages consist of text, pictures, quizzes, and animations of everyday stories, aimed at disease prevention and early treatment. The baseline and immediate postintervention assessments were completed in Iringa, Tanzania in May 2019. The participants were interviewed by enumerators and completed questionnaires regarding health knowledge. Participants in the intervention group were exposed to 3 different health animations once on a tablet device. The participants' health knowledge was assessed again immediately after the exposure. The first follow-up survey was undertaken in August 2019. The InfoSpots with the digital health platform were thereafter launched in the intervention villages in November 2019. Qualitative interviews were undertaken in February 2020. The second follow-up was completed in June 2020.

RESULTS

A total of 600 participants have been enrolled in the trial. We will assess (1) the difference in knowledge scores between baseline and the immediate postintervention assessments in the intervention group and (2) the difference in knowledge scores between the intervention and control groups at baseline, 3 and 6 months post-DHI rollout. Since a randomized design did not prove feasible, potential confounders (eg, age, gender, education, and time of exposure) may be introduced, and results will be adjusted. Data analysis for the 35 qualitative interviews is currently ongoing, and perspectives and experiences related to use and nonuse of the InfoSpots are being explored.

CONCLUSIONS

The data have been collected, and the analysis is ongoing in this digital health study, aimed at evaluating the effects of a DHI based on relevant health messages. The publications of results can be expected this year.
