Health literacy as a social vaccine in the COVID-19 pandemic.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a novel virus in the coronavirus family, causing the coronavirus disease (COVID-19). Biomedical vaccines are key but alongside biomedical vaccines, a social vaccine can be similarly useful to prevent infection from SARS-CoV-2, if applied as a health promotion strategy. In order to slow down and control the spread of SARS-CoV-2, applying the social vaccine concept should be considered in parallel. From a health promotion perspective, a social vaccine is a process of social and political mobilization driven by governmental and non-governmental organizations aiming at populations by applying interventions such as health communication, education and mass media campaigns as well as determinant-based programs to address environmental factors influencing personal behavior and community capacities to cope with and overcome the societal burdens of COVID-19. In this context, health literacy is significant, as seen in the role it plays in empowering citizens during the COVID-19 pandemic and enabling them to deal with health information considering COVID-19. As a public health strategy, health literacy as a social vaccine will enable individuals and communities to mitigate the spread of the virus by understanding and applying information as provided through governments and health authorities. The aim of this article is to explore health literacy as a promising social vaccine and opportunity to utilize social vaccination and thus be considered as a key public health approach-both bottom-up and top-down-to support the combat of COVID-19 and future states of emergency.

Building health literacy system capacity: a framework for health literate systems.

The human and social implications of poor health literacy are substantial and wide-ranging. Health literacy represents the personal competencies and organizational structures, resources and commitment that enable people to access, understand, appraise and use information and services in ways that promote and maintain good health. A large-scale societal improvement of health literacy will require political buy-in and a systematic approach to the development of health literacy capacity at all levels. This article builds the case for enhancing health literacy system capacity and presents a framework with eight action areas to accommodate the structural transformation needed at micro, meso and macro levels, including a health literate workforce, health literate organization, health literacy data governance, people-centred services and environments based on user engagement, health literacy leadership, health literacy investments and financial resources, health literacy-informed technology and innovation, and partnerships and inter-sectoral collaboration. Investment in the health literacy system capacity ensures an imperative and systemic effort and transformation which can be multiplied and sustained over time and is resilient towards external trends and events, rather than relying on organizational and individual behavioural change alone. Nevertheless, challenges still remain, e.g. to specify the economic benefits more in detail, develop and integrate data governance systems and go beyond healthcare to engage in health literacy system capacity within a wider societal context.

Health literacy represents the personal competencies and organizational structures and resources enabling people to access, understand, appraise and use information and services in ways that promote and maintain good health. To meet the needs related to impact of poor health literacy, this article introduces a framework for the development of health literacy system capacity with eight action areas including the development of a health literate workforce, health literate organization, health literacy data governance, people-centred services and environments based on user engagement, health literacy leadership, health literacy investments and financial resources, health literacy-informed technology and innovation, and partnerships and inter-sectoral collaboration. Investment in health literacy system capacity ensures a future-proof effort that can be multiplied and sustained over time, rather than relying on organizational or individual behavioural change alone.

[THE CHALLENGE OF HEALTHY AGING WITH DIABETES: THE ISRAELI NATIONAL DIABETES COUNCIL GUIDELINES FOR TREATING OLDER PEOPLE].

INTRODUCTION: The prevalence of diabetes increases with age. Diabetes is a risk factor for many complications such as cardiovascular disease, kidney failure, stroke, neuropathy, and retinopathy. Data from recent years indicate that it is also a risk factor for cognitive impairment, dementia, functional disability and frailty. Diabetes is a disease that requires complex self-care capabilities; the individuals with diabetes are required to take medications on time, examine their feet, exercise, maintain a balance diet, preform daily glucose monitoring, cope with hypoglycemia and understand how differing life situations may effect glucose levels. All of these require intact cognitive and functional abilities. Thus, treatment plans should take into consideration the person's cognitive/functional state. Indeed, in the last several years many professional organizations such as the American Diabetes Association, the International Diabetes Federation, and the American Endocrinology Society have published guidelines for treating older people with diabetes. The Israeli National Diabetes Council, headed by Prof. Itamar Raz, in collaboration with other physician unions and other national councils, have recently authorized the Israeli guidelines for treating older people with diabetes. The Israeli guidelines include categorization of older adults with diabetes in relation to their functional status in order to reach determined treatment targets. According to the Israeli guidelines and in accordance with international guidelines, the treatment targets of the elderly person with diabetes should not be determined by the chronological age of the individuals but rather by their risk for functional deterioration. Older people with diabetes are categorized into three groups according to their risk for functional deterioration. Each category has unique glucose, blood pressure and lipid targets. The guidelines offer valid and reliable tools that, in addition to personal acquaintance with the patient, can help determine the level of risk of functional decline.

Communication, Health Literacy and a Systems Approach for Mitigating the COVID-19 Pandemic: The Case for Massive Vaccine Roll-out in Israel.

COVID-19 has created global challenges that only an effective vaccine, apparently, can lead the citizens of the world back to a sense of normalcy. While safe vaccines were developed, tested and approved at an extraordinary pace, concerns were raised regarding the public's response in accepting the vaccine on the population level. Israel was among the first countries to roll out a massive national campaign for COVID-19 vaccination, positioning Israel as the global lead in vaccine uptake. Priority for vaccination was given to high-risk groups: older and middle-age adults, healthcare workers, senior home residents and caregivers, people with chronic conditions, followed by teachers and soldiers. Contributing to the success of the operation thus far has been a systems approach beyond nationwide accessibility: building public trust through an integrated and familiar health system, a familiar technology (vaccine), transparency regarding vaccine safety information, culturally appropriate messages in digital and offline media, acknowledging diverse health literacy needs, and active participation and role-modeling by political/religious opinion leaders. Vaccine resistance and hesitancy may be encountered as the campaign progresses, and younger groups targeted. Future considerations include perceived benefits offered to people with vaccination and the role of health/digital literacy in preparedness policies. Ethical issues regarding the rights of those vaccinated, as well as those who have not, are explored.

Internal locus of control, health literacy and health, an Israeli cultural perspective.

The association between health literacy (HL) and health outcomes, including self-perceived health (SPH) has been well documented. Yet the complexity of this association is not yet completely clear. Drawing on the Health Literacy Scale (HLS) study in Israel, we examined the association between HL, Internal Health Locus of Control (IHLOC) and SPH among Jews and Arabs. A face-to-face survey was conducted among 242 Arabs and 358 Jews. The questionnaire measured SPH, IHLOC and two measures of HL: a European HLScale (HLS-EU-16) and the Hebrew/Arabic Health Literacy Test (H/AHLT), based on the Short Test Of Functional Health Literacy in Adults. Analysis included multivariable logistic regressions and bootstrapping to identify mediation effects. Among Jews, IHLOC seems to be a significant mediator between HL and SPH. IHLOC was strongly associated with SPH (OR = 6.13; CI = 3.2, 11.8), while HL was not significantly associated directly with SPH. Similar results were observed when using the H/AHLT as a measure of HL. Among Arabs a different pattern emerges; IHLOC was neither associated with SPH nor was it a mediator of the association between HL and SPH. The two measures of HL seem to have different associations with SPH among Arabs, as only H/AHLT was associated significantly with SPH, and not HLS-EU-16. Thus, those with higher levels of IHLOC assess their health as better than those with low IHLOC only among Jews, and not among Arabs. IHLOC seems to be a significant mediator between HL and SPH among some cultures. Among Arabs, only functional HL seems to be positively associated with SPH.

Generic health literacy measurement instruments for children and adolescents: a systematic review of the literature.

BACKGROUND: Health literacy is an important health promotion concern and recently children and adolescents have been the focus of increased academic attention. To assess the health literacy of this population, researchers have been focussing on developing instruments to measure their health literacy. Compared to the wider availability of instruments for adults, only a few tools are known for younger age groups. The objective of this study is to systematically review the field of generic child and adolescent health literacy measurement instruments that are currently available. METHOD: A systematic literature search was undertaken in five databases (PubMed, CINAHL, PsycNET, ERIC, and FIS) on articles published between January 1990 and July 2015, addressing children and adolescents ≤18 years old. Eligible articles were analysed, data was extracted, and synthesised according to review objectives. RESULTS: Fifteen generic health literacy measurement instruments for children and adolescents were identified. All, except two, are self-administered instruments. Seven are objective measures (performance-based tests), seven are subjective measures (self-reporting), and one uses a mixed-method measurement. Most instruments applied a broad and multidimensional understanding of health literacy. The instruments were developed in eight different countries, with most tools originating in the United States (n = 6). Among the instruments, 31 different components related to health literacy were identified. Accordingly, the studies exhibit a variety of implicit or explicit conceptual and operational definitions, and most instruments have been used in schools and other educational contexts. While the youngest age group studied was 7-year-old children within a parent-child study, there is only one instrument specifically designed for primary school children and none for early years. CONCLUSIONS: Despite the reported paucity of health literacy research involving children and adolescents, an unexpected number of health literacy measurement studies in children's populations was found. Most instruments tend to measure their own specific understanding of health literacy and not all provide sufficient conceptual information. To advance health literacy instruments, a much more standardised approach is necessary including improved reporting on the development and validation processes. Further research is required to improve health literacy instruments for children and adolescents and to provide knowledge to inform effective interventions.

Health literacy in childhood and youth: a systematic review of definitions and models.

BACKGROUND: Children and young people constitute a core target group for health literacy research and practice: during childhood and youth, fundamental cognitive, physical and emotional development processes take place and health-related behaviours and skills develop. However, there is limited knowledge and academic consensus regarding the abilities and knowledge a child or young person should possess for making sound health decisions. The research presented in this review addresses this gap by providing an overview and synthesis of current understandings of health literacy in childhood and youth. Furthermore, the authors aim to understand to what extent available models capture the unique needs and characteristics of children and young people. METHOD: Six databases were systematically searched with relevant search terms in English and German. Of the n = 1492 publications identified, N = 1021 entered the abstract screening and N = 340 full-texts were screened for eligibility. A total of 30 articles, which defined or conceptualized generic health literacy for a target population of 18 years or younger, were selected for a four-step inductive content analysis. RESULTS: The systematic review of the literature identified 12 definitions and 21 models that have been specifically developed for children and young people. In the literature, health literacy in children and young people is described as comprising variable sets of key dimensions, each appearing as a cluster of related abilities, skills, commitments, and knowledge that enable a person to approach health information competently and effectively and to derive at health-promoting decisions and actions. DISCUSSION: Identified definitions and models are very heterogeneous, depicting health literacy as multidimensional, complex construct. Moreover, health literacy is conceptualized as an action competence, with a strong focus on personal attributes, while also recognising its interrelatedness with social and contextual determinants. Life phase specificities are mainly considered from a cognitive and developmental perspective, leaving children's and young people's specific needs, vulnerabilities, and social structures poorly incorporated within most models. While a critical number of definitions and models were identified for youth or secondary school students, similar findings are lacking for children under the age of ten or within a primary school context.

Tobacco still a major killer-will we achieve the end game?

The game of tobacco use began in Europe in 1560 when the first tobacco seeds were sent from Lisbon to the king of France, by Jean Nicot. From kings' and nobles' exclusive use, it gradually and progressively became popular among the public, as a new player. Eighty-eight years ago (1929), Fritz Linkint, an extraordinary researcher in Germany, while reviewing existing evidence regarding a wide range of cancers potentially caused by smoking, indicated that smoking was a cause of respiratory disease. Despite the overwhelming accumulated evidence of the negative effects of nicotine intake, the prevalence of tobacco use is not expected to decline in the near future. What have we missed thus far in the game that claims more than seven million deaths annually worldwide? Although tobacco use is recognized as a major health problem, the persistent habit creates a dissonance between public health initiatives to reduce tobacco consumption and the choices citizens are making. To understand this dissonance, consideration first must be given to the social meaning attributed to smoking. Second, the political dissonance between health imperatives and social agendas is discussed with regard to relevant theory. Third, health promotion strategies can make a strong contribution to win the game from a negentropic perspective, that is to say, a public health vision that is structured towards an overarching goal.

The Association of Health Literacy with Health Behavior, Socioeconomic Indicators, and Self-Assessed Health From a National Adult Survey in Israel.

There is a growing need to understand how health literacy influences health outcomes in diverse populations. The aim of this study was to examine the relationship between health literacy, health behavior, sociodemographic indicators, and self-assessed health in the adult population in Israel while identifying populations at risk for low health literacy. A cross-sectional national survey was conducted among 600 adults randomly selected from a national database. The Health Literacy Survey-Europe-Q16 (HLS-EU-Q16) research instrument, adapted for use in Israel, was the basis for home interviews in Hebrew, Russian, and Arabic. Three levels of health literacy were distinguished: More than 31% of the sample had inadequate or problematic health literacy, and 69% showed likely sufficient health literacy. Logistic regression analyses showed that after we controlled for other determinants, years of education (ß = 1.8) and income (ß = 2.2) were significantly associated with health literacy. Multinomial logistic regression analysis showed that health literacy, along with age, was the strongest independent variable associated with self-assessed health. Thus, health literacy, strongly influenced by income and years of education, may play a key role in determining self-assessed health, a proxy health outcome, beyond sociodemographic variables. The study results contribute to understanding the role of health literacy in health disparities and identifying action areas for health promotion.

Developing Healthy Lifestyle Behaviors in Early Age-An Intervention Study in Kindergartens.

Childhood obesity prevention is a leading public health challenge requiring the adoption of healthy lifestyles at an early age. We examined how the kindergarten environment can promote eating sensibly, drinking water and becoming physically active. The effects of an intervention program among 42 Israeli kindergartens (1048 children, aged 4-6) whose teachers participated in a health education training program were compared to 32 kindergartens (842 children) whose teachers did not undergo this training program. An eight-month intervention program focused on knowledge/mathematical/logical/critical thinking, self-regulation/control acquisition, and sensible decision-making abilities. We hypothesized that nutrition and physical-exercise-oriented intervention programs, combining knowledge/mathematical logical thinking, would positively impact the quality of children's mid-morning snack and water consumption, their ability to express feelings following physical exercise, and the adoption of healthy lifestyles at home. The quality of mid-morning snacks and water consumption were observed in both groups pre- and post-intervention. Qualitative interviews documented children's subjective feelings following physical exercise. A significant improvement (p < 0.001) was observed in the mid-morning snacks composition and in water drinking habits in the intervention group; 80% of children offered a physiological explanation regarding energy expenditure processes following intense physical exercise. In conclusion, kindergarten interventions implemented by trained teachers can promote adoption of health behaviors necessary for obesity prevention.

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.

Media Health Literacy (MHL): development and measurement of the concept among adolescents.

Increasing media use among adolescents and its significant influence on health behavior warrants in-depth understanding of their response to media content. This study developed the concept and tested a model of Media Health Literacy (MHL), examined its association with personal/socio-demographic determinants and reported sources of health information, while analyzing its role in promoting empowerment and health behavior (cigarette/water-pipe smoking, nutritional/dieting habits, physical/sedentary activity, safety/injury behaviors and sexual behavior). The school-based study included a representative sample of 1316 Israeli adolescents, grades 7, 9 and 11, using qualitative and quantitative instruments to develop the new measure. The results showed that the MHL measure is highly scalable (0.80) includes four sequenced categories: identification/recognition, critical evaluation of health content in media, perceived influence on adolescents and intended action/reaction. Multivariate analysis showed that MHL was significantly higher among girls (ß = 1.25, P < 0.001), adolescents whose mothers had higher education (ß = 0.16, P = 0.04), who report more adult/interpersonal sources of health information (ß = 0.23, P < 0.01) and was positively associated with health empowerment (ß = 0.36, P < 0.0005) and health behavior (ß = 0.03, P = 0.05). The findings suggest that as a determinant of adolescent health behavior, MHL identifies groups at risk and may provide a basis for health promotion among youth.

Rebranding social distancing to physical distancing: calling for a change in the health promotion vocabulary to enhance clear communication during a pandemic.

Amidst the COVID-19 outbreak, the term 'social distancing' received immense attention in the mainstream and social media and was embraced by governments as a universal precaution to stem the coronavirus pandemic. 'Social distancing' belongs technically to a set of non-pharmaceutical infection control actions intended to stop or slow down the spread of a contagious disease. However, several weeks into the outbreak, scholars discussed whether the term was, in fact, misleading and could be counterproductive. To study the arguments, the study design included (1) analysis of the performance of the concepts 'social distancing' and 'physical distancing' based on Google Trends (15 February-15 June 2020); (2) analysis of the arguments used in media discussions of 'social distancing versus physical distancing' in the period 15 March-15 April 2020, derived from a Google search; and (3) a scientific literature review in PubMed. The study was conducted in English. The trend analysis showed the peak and the decrease of the relative popularity of 'social distancing' and 'physical distancing' during spring 2020. The thematic analysis of Google sources yielded an overview of arguments based on nine themes with two to five sub-themes reflecting on the misleading concept, the historical perspective, the sociological perspective, the public health perspective, alternative proposals regarding the social and the physical dimensions, the distinction of terms, the political choice, and the need for rebranding. Two papers were included in the scientific literature review, which both stressed the need for a change of terminology. In conclusion, the study emphasizes that the choice of terminology matters when life-saving public health messages are designed. It is therefore recommended to rebrand 'social distancing' to 'physical distancing' to enhance clear communication during the current COVID-19 pandemic in order to prepare for future pandemics.

Health Literacy, Primary Care Health Care Providers, and Communication.

BACKGROUND: Decision-makers and health professionals face challenges in providing quality medical services while optimizing diminishing resources. Health literacy is associated with health outcomes and health system costs and influences the way in which communication is managed in the health system. OBJECTIVE: This study examined the association between the level of health literacy of service providers in the community, their awareness of health literacy, their attitudes toward health literacy promotion, and the way in which they communicate with patients with low health literacy. METHODS: A cross-sectional analytic study was conducted among 50 physicians and 50 administrative staff members in community clinics of the Maccabi Health Maintenance Organization in Israel. KEY RESULTS: Significant positive associations were found (p < .05) between the level of health literacy, the attitudes toward health literacy promotion, and the degree to which special communication techniques were used when treating patients with low health literacy. Significant associations were found (p < .01) between the level of awareness, as well as the attitudes toward health literacy promotion and the degree to which communication techniques were applied. Higher health literacy is associated with more favorable attitudes toward health literacy promotion. Additionally, a significant positive association (p < .01) was found between the attitudes toward health literacy promotion and the use of communication techniques. No mediation was found among the research variables. CONCLUSIONS: To the best of our knowledge, this is the first study that examines health literacy among physicians. The results indicate gaps in the awareness of, and attitudes toward, health literacy among community health care providers, thus suggesting the need for developing and applying guidelines for improving efforts of health system providers regarding health literacy and for applying recommended tools for health communication. [HLRP: Health Literacy Research and Practice. 2021;5(3):e194-e200.] Plain Language Summary: This study examined the link between the health literacy of health care providers (e.g., physicians, service administrators), their awareness and attitudes toward health literacy promotion, and how they communicate with patients with low health literacy. The findings showed significant and positive relationships between these aspects of health literacy as well as gaps in the health care system that need to be addressed.

To Adapt or Not to Adapt: The Association between Implementation Fidelity and the Effectiveness of Diabetes Self-Management Education.

Self-management education (SME) is a key determinant of diabetes treatment outcomes. While SME programs are often adapted for implementation, the impact of adaptations on diabetes SME effectiveness is not well documented. This study evaluated the impact of the implementation fidelity of diabetes SME programs on program effectiveness, exploring which factors influence implementation fidelity. Data from 33 type 2 diabetes SME program providers and 166 patients were collected in 8 countries (Austria, Belgium, Germany, Ireland, UK, Israel, Taiwan and USA). Program providers completed a questionnaire assessing their adherence to the program protocol and factors that influenced the implementation. Patients answered a pre-post questionnaire assessing their diabetes-related health literacy, self-care behavior, general health and well-being. Associations between implementation fidelity and outcomes were estimated through logistic regressions and repeated measures MANOVA, controlling for potential confounders. Adaptations of the program protocol regarding content, duration, frequency and/or coverage were reported by 39% of the providers and were associated with better, not worse, outcomes than strict adherence. None of the factors related to the participants, facilitating strategies, provider or context systematically influenced the implementation fidelity. Future research should focus on individual and contextual factors that may influence decisions to adapt SME programs for diabetes.

Health promotion preparedness for health crises - a 'must' or 'nice to have'? Case studies and global lessons learned from the COVID-19 pandemic.

The current COVID-19 pandemic has exposed missing links between health promotion and national/global health emergency policies. In response, health promotion initiatives were urgently developed and applied around the world. A selection of case studies from five countries, based on the Socio-Ecological Model of Health Promotion, exemplify 'real-world' action and challenges for health promotion intervention, research, and policy during the COVID-19 pandemic. Interventions range from a focus on individuals/families, organizations, communities and in healthcare, public health, education and media systems, health-promoting settings, and policy. Lessons learned highlight the need for emphasizing equity, trust, systems approach, and sustained action in future health promotion preparedness strategies. Challenges and opportunities are highlighted regarding the need for rapid response, clear communication based on health literacy, and collaboration across countries, disciplines, and health and education systems for meaningful solutions to global health crises.

Health Literacy in Israel - From Measurement to Intervention: Two Case Studies.

This report focuses on opportunities, challenges and outcomes of health literacy related interventions in Israel, based on health literacy measurement. The importance of a system's and community approaches are discussed, as is cultural appropriateness. Two case studies are highlighted - the first on childhood immunization and the second on self-management of chronic health situations. In the second example, a combination of community, media, digital, and face-to-face interventions comprise a broad approach to intervention. The impact and some findings are presented, including conclusions derived from each initiative.

International Perspective on Health Literacy and Health Equity: Factors That Influence the Former Soviet Union Immigrants.

Among the world's 272 million international migrants, more than 25 million are from the former Soviet Union (FSU), yet there is a paucity of literature available about FSU immigrants' health literacy. Besides linguistic and cultural differences, FSU immigrants often come from a distinct healthcare system affecting their ability to find, evaluate, process, and use health information in the host countries. In this scoping review and commentary, we describe the health literacy issues of FSU immigrants and provide an overview of FSU immigrants' health literacy based on the integrated health literacy model. We purposefully consider the three most common locations where FSU immigrants have settled: the USA, Germany, and Israel. For context, we describe the healthcare systems of the three host countries and the two post-Soviet countries to illustrate the contribution of system-level factors on FSU immigrants' health literacy. We identify research gaps and set a future research agenda to help understand FSU immigrants' health literacy across countries. Amidst the ongoing global population changes related to international migration, this article contributes to a broad-scope understanding of health literacy among FSU immigrants related to the system-level factors that may also apply to other immigrants, migrants, and refugees.

Trends in Tobacco Use among Children and Adolescents in Israel, 1998-2015.

OBJECTIVES: This study aims to measure trends in cigarette smoking among children and adolescents in Israel, focusing on school grade, sex, and ethnicity. We hypothesized that smoking would be higher among boys and Arab-Israelis, rates would grow with age, and there would be a decline over time. METHODS: Data were derived from the Health Behavior in School-aged Children study between 1998 and 2015 in Israel. The total sample included 56,513 students in grades 6, 8, and 10, with 29,411 girls and 27,102 boys. Descriptive analysis described trends of smoking behavior according to grade, sex, ethnicity, family affluence, and year of study. multivariate logistic regression analysis examined predicting variables. RESULTS: Smoking was higher among boys in all grades, ethnic groups, and years of study, with the highest frequencies among Arab-Israelis. Trends over the years show a decline from 1998 to 2004, followed by an increase for both sexes. The increase was more prominent among girls. Logistic regression analysis revealed strong associations between smoking and grade, sex, ethnicity, and year of study. CONCLUSIONS: The results of this study can significantly enhance the development and implementation of smoking prevention and control programs among students in Israel.
