Health literacy among adolescents and young adults in the Eastern Mediterranean region: a scoping review.

OBJECTIVES: For adolescents and young adults, most health literacy research has been conducted in Western countries, but few studies have been conducted in the Eastern Mediterranean region (EMR). This review aimed to explore the existing health literacy research in the EMR in addition to the levels of health literacy and its associated factors among adolescents and young adults. METHODS: The search, conducted using the PubMed/MEDLINE, EBSCOhost/CINAHL plus, Web of Science and J-STAGE databases, was initially performed on 16 June 2022 and later updated on 1 October 2022. Studies that targeted 10-25 years old persons, conducted in any of the EMR countries and that used the health literacy concept and/or described its levels or predictors were included in the review. Content analysis was used for data extraction and analysis. Data related to the study methods, participants, outcome variables and health literacy were extracted. RESULTS: The review included 82 studies, most of which were conducted in Iran and Turkey and adopted a cross-sectional design. Half of the studies showed that more than half of adolescents and young adults had low or moderate health literacy. Nine studies applied university-based or school-based health education interventions to improve health literacy, which was also predicted by demographic and socioeconomic factors and internet usage. Little attention was paid to assessing the health literacy of vulnerable people, such as refugees and those with a disability and exposed to violence. Finally, various health literacy topics were investigated, including nutrition, non-communicable diseases, media and depression. CONCLUSION: Health literacy levels were low-to-moderate in adolescents and young adults in the EMR. To promote health literacy, it is recommended to use school-based health education and attempt to reach adolescents and young adults through social media platforms. More attention should be paid to refugees, people with disabilities and those exposed to violence.

Health literacy as a key to improving weight status among Palestinian adolescents living in chronic conflict conditions: a cross-sectional study.

OBJECTIVE: To examine the moderating role of health literacy in the association between direct exposure to violence and weight status among Palestinian adolescents. DESIGN: A household cross-sectional study conducted in 2017. SETTING: A Palestinian district of the West Bank. PARTICIPANTS: Palestinian adolescents aged 11-16 years. RESULTS: After excluding underweight adolescents from the 1200 who were initially recruited, the data of 1173 adolescents were analysed. A high proportion (62%) of adolescents were directly exposed to violence. The prevalence of obesity and overweight was 6.5% and 17.1%, respectively. The odds of obesity and overweight were 2.8 and 1.8 times higher among adolescents who were not exposed to domestic and school violence when they had low health literacy in the communication subscale. The odds of obesity were 62% and 57% lower among adolescents with high functional health literacy when exposed to domestic and school violence and to any form of violence, respectively. Among adolescents who were not exposed to any form of violence, those who had high health literacy in the communication subscale were 72% less likely to be obese compared with those who had low health literacy. CONCLUSIONS: Health literacy moderated the association between direct exposure to violence and weight status. When health literacy levels were higher, lower obesity rates were observed among adolescents who were directly exposed to any form of violence or exposed either to political violence only or domestic and school violence only. The results warrant further investigation of the role of health literacy in adolescent health. It is recommended that policy-makers integrate the health literacy concept into both education and health systems.

Exploring health literacy and its associated factors among Palestinian university students: a cross-sectional study.

Health literacy plays an important role in personal and community health. Since university is a turning point when young adults begin to take responsibility for their own health, understanding university students' health literacy levels is crucial. To this end, we aimed to explore health literacy and its associated factors among Palestinian university students. We conducted a cross-sectional study at Birzeit University in the Ramallah district. We recruited 472 students using convenience sampling at six on-campus cafeterias. The 44-item Arabic version of the Health Literacy Questionnaire was used to measure students' health literacy levels, while a locally developed distress scale was used to measure students' distress levels. We stratified the multiple regression model for the health literacy score by gender. Students' average total health literacy score was 135.3 (SD 20.9), with male students scoring significantly higher than female students. A higher health literacy score was significantly associated with having a father with a higher level of education, a higher frequency of medical checkups, higher self-reported health status, and consulting a higher number of sources for health-related information. High distress levels were associated with lower levels of health literacy, especially among female students. This study provides the first evidence on Palestinian university students' health literacy levels. Tailored health education and promotion are required for students with low parental education and moderate to high distress. Future research is required to explain the gender differences in health literacy and distress among university students.

Psychometric properties of an Arabic-language health literacy assessment scale for adolescents (HAS-A-AR) in Palestine.

OBJECTIVES: Health literacy research in Palestine is limited, and a locally validated tool for use among adolescents has been unavailable until now. Therefore, this study aimed to adapt health literacy assessment scale for adolescents (HAS-A) into Arabic language (HAS-A-AR) and Palestinian context and to investigate its psychometric properties. DESIGN: We conducted a cross-sectional household survey using a stratified random sample and household face-to-face interviews. SETTING AND PARTICIPANTS: We conducted 1200 interviews with sixth to ninth graders in the Ramallah and al-Bireh district of the West Bank, Palestine in 2017. METHODS: We translated and adapted HAS-A to be sensitive to the Palestinian context and tested its psychometric properties. We evaluated face and content validity during the back-translation process and checked for construct validity through exploratory factor analysis (EFA). We tested for internal consistency using Cronbach's alpha, MacDonald's omega test and the greatest lower bound (GLB). Furthermore, we calculated the scale's average inter-item correlation. RESULTS: EFA revealed that HAS-A-AR has a similar structure to the original HAS-A. It extracted three factors (communication, confusion and functional health literacy) whose eigenvalues were >1. Together they explained 57% of the total variance. The proportions of adolescents with high levels of communication, confusion and functional health literacy were 45%, 68% and 80%, respectively. Cronbach's alpha, MacDonald's omega and the GLB values for communication subscale were 0.87, 0.88 and 0.90, and they were 0.78, 0.77 and 0.79 for confusion subscale, while they were 0.77, 0.77 and 0.80, respectively, for functional healthy literacy subscale. The average inter-item correlation for the subscales ranged between 0.36 and 0.59. CONCLUSION: HAS-A-AR is a valid and reliable health literacy measuring instrument with appropriate psychometric properties. HAS-A-AR is currently available for use among adolescents in Palestine and the surrounding Arab countries with similar characteristics as Palestine, including language, culture and political instability.

The effectiveness of counselling interventions in reducing HbA1c concentrations in patients with type 2 diabetes: a modelling study.

BACKGROUND: The burden of type 2 diabetes is increasing rapidly in the occupied Palestinian territory. Different counselling interventions have been applied worldwide to reduce HbA1c concentrations in patients with type 2 diabetes. Achieving good glycaemic control is important for prevention of complications of type 2 diabetes. The aim of this modelling study was to assess the effectiveness of different counselling interventions in improving glycaemic control in patients with type 2 diabetes. METHODS: The scientific literature was reviewed to identify relevant interventions that can reduce HbA1c concentrations in patients with type 2 diabetes. We included articles describing interventions tested at the primary health-care level and targeting patients with type 2 diabetes. Based on WHO's "Best Buys", and taking into consideration their feasibility, acceptability, and potential effectiveness, we identified different forms of counselling interventions at the primary health-care level. The effect of each identified intervention on HbA1c concentrations and the duration of this effect were collected in predefined tables. A regression line was plotted to find an estimate of the effect of each intervention through calculating the correlation between the changes in HbA1c from each intervention versus the duration of the intervention. The unstandardised ß-coefficient was identified for each intervention to predict its effectiveness in reducing HbA1c concentrations. FINDINGS: We identified three main effective counselling interventions at the primary health-care level: (1) individual counselling intervention by multidisciplinary teams of health-care professionals, which provided individual counselling sessions depending on the patients' glycaemic control status; (2) the community health-worker intervention, which provided a set of home counselling visits for patients with uncontrolled type 2 diabetes; and (3) short message service (SMS)-based intervention (sending patients a number of counselling SMS weekly). All interventions were effective in reducing mean HbA1c concentrations in patients with type 2 diabetes. The SMS-based intervention was the most effective (ß=0·65, R2=0·10), followed by the community health-worker intervention (ß=0·27, R2=0·28) and the individual counselling intervention (ß=0·14, R2=0·01). INTERPRETATION: We compared the effectiveness of a set of interventions that are considered relativity low cost and applicable at the level of primary health care (the "Best Buys"). Implementing at least one of these effective interventions within the Palestinian health-care system could help improve glycaemic control and eventually reduce the prevalence of complications associated with type 2 diabetes. Controlling HbA1c concentration will not only reduce the epidemiological burden of type 2 diabetes and its complications but it will also reduce the economic burden within Palestinian health-care system.
