Salt: a narrative review and local policy initiatives in Israel.

High salt intake is a well-known risk factor for cardiovascular disease (CVD). Some recent prospective studies have challenged the salt-CVD link. We conducted a narrative review based on a systematic search and provided a national policy update. We reviewed 14 observational prospective studies in healthy adults, reporting the association between sodium intake and excretion or reduction and CVD incidence. Validated by cohort studies, recommended sodium consumption levels (< 1.5-2 gram per day) are still relevant for the prevention of CVD in adults. We discussed the findings and policy initiatives implemented in Israel. Such initiatives included voluntary and mandatory food labeling, and culturally tailored educational programs. The Ministry of Health in Israel initiated a salt reduction policy in recent years-aimed for the future of the industry as well as the population.

Children in the Anthroposophical Education System Have Lower Rates of Obesity, and Higher Rates of Health Promoting Behaviors.

BACKGROUND: The anthroposophical philosophy is a holistic educational and lifestyle approach. Limited information exists on the health-promoting behavioral norms and obesity rates among children living anthroposophical vs. conventional lifestyles. AIMS: This study aims to compare the prevalence of childhood obesity, and parents' perceptions of their children's food environment, between anthroposophical and conventional education systems. METHODS: We performed a cross-sectional analysis of the National Anthropometric Measurement Survey for first grade students in Israel, comparing anthroposophical schools with matched conventional schools. Additionally, an online survey was distributed among parents of children in both school systems, assessing children's eating norms and dietary intake. RESULTS: Overweight and obesity rates were higher among students in conventional schools (n = 205,500) compared to anthroposophical schools (n = 2247) (11.2% vs. 9.6%, and 7.8% vs. 4.8%, respectively; Pv < 0.001). Anthroposophical schools were perceived by more parents to have health-promoting curricula, health promoting teacher behavior, and health promoting social dietary norms, while their children's dietary intake was perceived as healthier both in school and in the after-school, social, and familial environment (Pv < 0.001). CONCLUSIONS: Children in anthroposophical education exhibited lower overweight and obesity rates, and engaged in more health-promoting behaviors. Further research is needed to explore the relationship between the anthroposophical lifestyle and childhood obesity, and to identify effective anthroposophical strategies for health promotion among children.

Adolescent body mass index and cognitive performance: a nationwide study of 2.48 million Israeli adolescents.

IMPORTANCE: The increased incidence of adolescent obesity over recent decades may be associated with lower cognitive performance than the expected potential. OBJECTIVE: We aimed to assess the association between adolescent body mass index (BMI) and cognitive function. DESIGN: A nationwide, cross-sectional, population-based study. SETTING: Pre-recruitment evaluation for military service during 1967-2018. PARTICIPANTS: All Israeli-born adolescents, 1 459 522 males and 1 027 953 females aged 16 to ≤20 years. EXPOSURES: Weight and height were measured to calculate BMI. MAIN OUTCOME: Cognitive performance was assessed by using a validated intelligence-quotient-equivalent test and was standardized to the year- and sex-Z-score. For 445 385 persons, parental cognitive scores could be identified. Multinomial logistic regression models were applied. RESULTS: Among male adolescents with severe obesity, 29.4% achieved a cognitive score below the 25th percentile, compared with 17.7% among their normal-weight (50th-84th percentile) counterparts. A J-shaped relation was observed between BMI and the odds ratio (OR) for a low cognitive score among male adolescents: underweight, 1.45 (1.43-1.48); overweight, 1.13 (1.12-1.15); mild obesity, 1.36 (1.33-1.39); and severe obesity, 1.58 (1.52-1.64). Similar findings were observed in females. For both sexes, point estimates were overall consistent in models adjusted for sociodemographic confounders, coexisting morbidities, and parental cognitive scores. Examinees with abnormal BMI had higher ORs for a lower-than-expected cognitive score, based on their parents' data as adolescents, in a manner that depends on obesity severity. CONCLUSION AND RELEVANCE: Obesity, is associated with increased odds for a lower cognitive performance, and the inability to fully achieve cognitive potential, regardless of sociodemographic background.

Challenges and obstacles implementing evidence-based food fortification policy in a high-income country.

The World Health Organization (WHO) recognizes food fortification as one of the most cost-effective and beneficial public health measures available. Mass fortification policies and regulations can reduce health disparities, including in high-income countries, by improving micronutrient intake among food-insecure or high-risk populations without changing their diet or behavior. While international health organizations have traditionally prioritized technical assistance and grants to medium and low-income countries, it is important to recognize that micronutrient deficiencies may also pose an important yet underappreciated public health problem in many high-income countries. Nevertheless, some high-income countries, including Israel, have been slow to adopt fortification, due to a variety of scientific, technological, regulatory, and political barriers. Overcoming these barriers requires an exchange of knowledge and expertise among the all stakeholders to achieve cooperation and broad public acceptance within countries. Similarly, sharing the experience of countries where the matter is in play may help inform efforts to advance fortification globally. Here we share a perspective on progress and barriers to achieve this goal in Israel, to inform efforts made to avoid the regrettable waste of unrealized human potential from prevalent yet preventable nutrient deficiency conditions, in Israel and beyond.

The paradoxical effects of professional stereotypes on the quality of care by interprofessional teams: The contingent effects of team faultlines, team stereotypes, and championship behaviors.

Background: Despite calls for interprofessional teamwork to ensure quality care in healthcare settings, interprofessional teams do not always perform effectively. There is evidence that professional stereotypes inhibit effective interprofessional teamwork, but they haven't been explored as a phenomenon that impacts team's performance and quality of care. Objectives: To focus on professional stereotypes emerging in interprofessional teams and examine the contingency effects of interprofessional team's faultlines, professional stereotypes, and leader's championship behaviors on team's quality of care. Methods: A cross-sectional nested sample of 59 interprofessional teams and 284 professionals, working in geriatric long-term-care facilities in Israel. Additionally, five to seven of the residents of each facility were randomly sampled to obtain the outcome variable. Data collection employed a multisource (interprofessional team members), multimethod (validated questionnaires and data from residents' health records) strategy. Results: The results indicated that faultlines are not directly harmful to team's quality of care; instead, they are likely to impact quality of care only when team stereotypes emerge. Furthermore, whereas teams typified by high professional stereotypes require person-oriented championship leadership, for teams typified by low team stereotypes, championship leadership harms the quality of care they provide. Conclusion: These findings have implications for handling interprofessional teams. Practically, leaders must be well-educated to better analyze team members' needs and maintain the appropriate leadership style.

Attitudes and perceived knowledge of health professionals on the food labelling reform in Israel.

OBJECTIVES: To assess the attitudes and perceived knowledge of health professionals regarding the food product judgemental-labelling reform that began in January 2020 in Israel. DESIGN: Cross-sectional survey. SETTINGS: An online survey among health professionals working in the Israeli health system. PARTICIPANTS: 456 participants (118 physicians, 207 nurses, 131 nutritionists). RESULTS: Most respondents (89·9 %) were women, 36 % had over 20 years of professional experience. All nutritionists, 96·6 % of physicians and 94·7 % of nurses reported hearing about the reform, and most (88·9 % of nurses, 76·3 % of physicians and 75·6 % of nutritionists) claimed supporting the reform to a great or very great extent. Most respondents believe they should discuss issues related to healthy eating with their patients (91·8 % of nurses, 94·9 % of physicians and all nutritionists), but only about half (47·5 % of physicians and 57·0 % of nurses) reported that they have sufficient knowledge in this field, particularly about food labelling. Almost two-thirds of nutritionists (60·3 %) reported instructing patients to change their food intake according to labelling v. 40·1 % and 34·7 % of nurses and physicians, respectively. Only some respondents felt that they could influence their patients' nutrition habits. Most participants believe that additional regulatory measures should also be used to promote healthy nutrition. CONCLUSIONS: There is a gap between the desire of physicians and nurses to provide nutritional guidance to the public and their actual knowledge about the labels' meaning as well as their competencies in providing nutrition counselling. When formulating a reform, policymakers should provide clear guidelines about the expectations of implementing it in therapeutic practice.

Impact of the COVID-19 pandemic on breastfeeding in Israel: a cross- sectional, observational survey.

BACKGROUND: Since March 2020, the world has been coping with the COVID-19 pandemic. One group particularly affected were mothers of newborns. The Israeli government imposed three lockdowns, with the first from 14 March to 11 May 2020. It had the strictest rules, with effects among mothers including panic and stress. These mothers coped with new challenges as they were often without help from the extended family, could not meet lactation counsellors in person, and stayed longer on maternity leave. METHODS: A cross-sectional, observational study collected data via an online anonymous survey in Israel. From 27 April 2020 to 11 May 2020, the survey was distributed through Facebook groups for breastfeeding mothers. It contained 32 multiple choice and 10 open questions. Multivariate logistic regression analysis, with adjustment for potential factors, was performed to determine the pandemic-related factors influencing breastfeeding, including the decision to breastfeed longer than planned. RESULTS: Five hundred eighty women participated in the survey. Most mothers were over 30, (mean age 32.55), married with an academic degree (81.5%). 127 (22%) women reported changes in their lactation plans. 85 (15%) responded that due to the COVID -19 pandemic they extended their breastfeeding period and 42 (7%) reported shortening it. A significant relationship was found between this extension and returning to work later than expected adjusted OR = 2.38 95% CI 1.46,3.87). When asked to rank steps national health authorities should take to encourage breastfeeding, the highest agreement (96%) was with maternity leave extension. More than 90% believed that receiving breastfeeding counselling at home and/or in hospital will encourage breastfeeding. CONCLUSIONS: This study demonstrated that most women did not change their breastfeeding patterns because of the lockdown though some did experience difficulties. Some lengthened their breastfeeding period, as, due to the pandemic, they stayed home longer than expected. This finding should be considered for future emergency situations.

Results of the national biomonitoring program show persistent iodine deficiency in Israel.

BACKGROUND: Adequate iodine intake is essential for human health, for normal thyroid function, and for attainment of full intellectual potential in children. In light of Israel's lack of a mandatory salt fortification policy, heavy reliance on desalination and low iodine intake from dairy products and seafood, there is concern in Israel that the population is iodine deficient. Indeed, the first Israeli National Iodine Survey in 2016 found a median urinary iodine concentration (UIC) of 83 µg/L among school age children, falling below the WHO's adequacy range of 100-299 µg/L for children. METHODS: In the framework of the National Human Biomonitoring Program in Israel, spot urine samples and questionnaire data were collected from 166 healthy children aged 4-12 years in 2020-2021. Urinary iodine concentrations were measured at the Ministry of Health National Biomonitoring Laboratory, using mass spectrometry. An international comparison of median urinary iodine concentrations (UIC) was performed taking into consideration the levels of desalinated water per capita, and fortification policies. RESULTS: The overall median (interquartile range [IQR]) UIC was 80.1 µg/L (44.7-130.8 µg/L) indicating that the population's iodine status has not improved in the five years that have passed since inadequacy was first identified. When comparing 13 countries with population size above 150,000, whose desalinated water per capita was at least 1 m3, Israel and Lebanon were the only countries with median UIC below the WHO adequacy range. CONCLUSIONS: There is an urgent need for mandatory salt fortification in Israel. Based on our international comparison, we conclude that the potential impact of desalination on iodine intake can be compensated for using the implementation of salt fortification policy. This study highlights the critical need for public health surveillance of nutritional and environmental exposures using human biomonitoring, with emphasis on vulnerable populations such as pregnant women and children.

The effect of lifestyle intervention on cardiometabolic risk factors in mental health rehabilitation hostel residents at-risk: a cluster-randomized controlled 15-month trial.

OBJECTIVE: Cardiometabolic disorders contribute to morbidity and mortality in people with severe mental illnesses (SMI), yet lifestyle-intervention efficacy in patients with SMI is unclear. Israel's unique mental-health rehabilitation hostels (MHRHs) provide housing to subjects with SMI. We tested how multi-component lifestyle intervention affects cardiometabolic risk-factors in at-risk SMI populations residing in MHRHs. METHODS: In a prospective, cluster-randomized, controlled study, six MHRHs, paired by residents' functioning level, were randomized to lifestyle intervention (nutrition education, physical education), or usual care. Subjects recruited included those with ≥1 of: BMI > 25 kg/m2; plasma triglycerides ≥150 mg/dL; HbA1c ≥ 5.7%; fasting plasma glucose ≥ 100 mg/dL and plasma HDL < 40(men)/ 50(women) mg/dL. Primary outcome was BMI change after 15 months; other outcomes were plasma lipids levels and glycemic control. Low cooperation in one MHRH pair led to their exclusion, the others were assigned to intervention or control. RESULTS: Eighty residents were enrolled to intervention groups and 74 to control. Compared to baseline, intervention-arm participants experienced improvements in BMI (-0.83 kg/m2 [-1.36, -0.29] 95%CI), triglycerides (-30.60 mg/dL [-49.39, -11.82]95%CI) and LDL (-15.51 mg/dL [-24.53, -6.50]95%CI) (all P ≤ 0.003). BMI improvement correlated with number of dietitian consultations (r = -0.30; P = 0.001). No significant differences were found between treatment arms in BMI (-0.46 kg/m2 [-1.11, 0.18]95%CI;P = 0.189), triglycerides (-24.70 mg/dL [-57.66, 8.25]95%CI), LDL (-9.24 mg/dL [-20.50, 2.03]95%CI), HDL and glycemic control. CONCLUSIONS: Lifestyle intervention significantly improved BMI, LDL and triglycerides compared to baseline in at-risk MHRHs residents with SMI, yet compared to usual care the differences did not reach statistical significance. The association between the number of dietitian's consultations and BMI improvement suggests that programs should highlight participants' adherence.

Urban Forest Health Intervention Program to promote physical activity, healthy eating, self-efficacy and life satisfaction: impact on Israeli at-risk youth.

The aim of this study was to evaluate an urban forest intervention program effect on physical activity, healthy eating habits, self-efficacy and life satisfaction (LS) among Israeli at-risk youth. The quasi-experimental study ran from September 2016 to June 2017; participants were randomly selected. There were 76 total study participants: 53 in the intervention and 23 in the control group. Participants ranged in age from 15 to 18 years. Questionnaires were administered to intervention and control groups before and after the intervention. Univariate and multivariable analyses evaluated the intervention effect. Repeated measures analyses of covariance were calculated to assess change in group differences. An increase was found in measures of physical activity in the intervention group (p < 0.001), while no change was noted in the control group. Healthy eating increased in both groups (p = 0.007), with no significant difference between them (p = 0.165). Unhealthy eating decreased significantly in the intervention group (p = 0.002) and increased in the control group (p = 0.007). Self-efficacy increased in the intervention group (p < 0.001), while no change was noted in the control group (p = 0.353). Likewise, LS increased in the intervention group (p < 0.001), while no change was found in the control group (p = 0.657). Findings indicate that the intervention was efficacious in increasing physical activity, healthy eating habits, self-efficacy, and LS. The effectiveness of this intervention among larger samples is warranted in future prospective studies.

Current use of nutrition facts tables and attitudes towards new red and green front-of-package labels among Israeli consumers.

Front-of-package labels (FOPL) are designed to simplify nutrition information and to help consumers make healthier food choices. The Israeli government has implemented new regulations requiring mandatory red warning FOPL for high levels of sodium, sugar, or saturated fats. A voluntary green positive FOPL for products fitting the national nutritional recommendations was concurrently encouraged. In order to characterise adult consumers' current use of Nutrition Facts Tables (NFT) and their attitudes towards the new FOPL, a nationally representative cross-sectional telephone survey was conducted. Most of the 1,042 survey respondents reported frequent NFT use (76.2%) and intentions to purchase fewer red-labelled (81.1%) and more green-labelled products (85.0%). Consumers with higher BMI and lower education expressed higher intentions to use the new FOPL, but not higher current use of NFT. This finding suggests that these high-risk groups, which the new labels are meant to target, may indeed benefit from the new policy.

Methodology and implementation of the WHO European Childhood Obesity Surveillance Initiative (COSI).

Establishment of the WHO European Childhood Obesity Surveillance Initiative (COSI) has resulted in a surveillance system which provides regular, reliable, timely, and accurate data on children's weight status-through standardized measurement of bodyweight and height-in the WHO European Region. Additional data on dietary intake, physical activity, sedentary behavior, family background, and school environments are collected in several countries. In total, 45 countries in the European Region have participated in COSI. The first five data collection rounds, between 2007 and 2021, yielded measured anthropometric data on over 1.3 million children. In COSI, data are collected according to a common protocol, using standardized instruments and procedures. The systematic collection and analysis of these data enables intercountry comparisons and reveals differences in the prevalence of childhood thinness, overweight, normal weight, and obesity between and within populations. Furthermore, it facilitates investigation of the relationship between overweight, obesity, and potential risk or protective factors and improves the understanding of the development of overweight and obesity in European primary-school children in order to support appropriate and effective policy responses.

The role of caloric intake in the association of high salt intake with high blood pressure.

Since current recommendations call for a substantial reduction in overall sodium consumption, we tested whether or not these recommendations are implemented in common large subpopulations such as those with abnormal weight or hypertension in the current high sodium, high-calorie nutritional environment. In a national representative cross-sectional survey of the community-dwelling subjects aged 25-65 years conducted in Israel between 2015 and 2017, 582 randomly selected subjects completed health and dietary questionnaires, underwent blood pressure and anthropometric measurements and collected 24-h urine specimens, to assess dietary sodium intake. Overall mean 24-h sodium excretion was 3834 mg, more than double the recommended upper intake for adults < 1500 mg/day. Sodium excretion was directly related to caloric intake and blood pressure and linked to the presence of hypertension and overweight/obesity. The highest sodium excretion was seen in overweight/obese hypertensive subjects. This recent national survey shows a high consumption of sodium in the Israeli population and a dose-response association between caloric intake and urinary sodium excretion, independent of BMI and hypertension. Nevertheless, overweight/obese subjects with hypertension consume (excrete) more sodium than other BMI/ blood pressure-related phenotypes and may thus comprise a target subpopulation for future efforts to reduce sodium intake.

Health Status, Eating, and Lifestyle Habits in the Long Term Following Sleeve Gastrectomy.

INTRODUCTION: Sleeve gastrectomy (SG) is an established bariatric procedure. However, long-term data on eating and lifestyle behaviors and their effect on weight outcomes are scarce. Therefore, this study aimed to examine these long-term behaviors and their associations to weight outcomes following SG. METHODS: A long-term follow-up study (>5 years post-surgery) of 266 adult patients admitted to a primary SG surgery during 2008-2012 and who participated in a pre-surgery study was conducted. Data on pre-surgery demographics, anthropometrics, and medical status were obtained from the patients' medical records. Data on long-term health status, anthropometrics, lifestyle and eating habits, eating pathologies, follow-up regime, and satisfaction from the surgery were collected by an interview phone calls according to a structured questionnaire. RESULTS: Data of 169 patients were available before and 7.8±1.0 years post-SG. Their baseline mean age was 41.8±11.3 years, and 71.6% of them were females. The mean post-surgery excess weight loss (EWL) was 53.2±31.2%, and 54.2% had EWL of ≥50%. Eating 3-6 meals per day, not having the urge to eat after dinner, separating liquids from solids, avoiding carbonated beverages, and performing physical activity were related to better weight-loss outcomes (P≤0.026). However, frequent need for eating sweets, binge eating, and feeling guilty or sad after eating were related to worse weight-loss outcomes (P≤0.010). Furthermore, only a minority reported taking a multivitamin and participating in follow-up meetings after more than 1 year since the surgery (≤21.3%). CONCLUSIONS: In the long term following SG, approximately half achieved EWL of ≥50%, and physical activity, certain eating patterns, and eating pathologies were related to weight outcomes.

Development of Criteria for a Positive Front-of-Package Food Labeling: The Israeli Case.

Efforts to shape the food environment are aimed at reducing diet-related co-morbidities. Front-of-package labeling (FOPL) may support the consumers to make an informed decision at the point of purchase and encourage industry to reformulate food products. The Israeli Ministry of Health (MOH) implemented a unique FOPL system, using two colors: A mandatory warning (red) label alongside a voluntary positive (green) label. An independent Scientific Committee, from academia, the healthcare system, and MOH was appointed to determine the core principles for the positive FOPL. The criteria were based on the Mediterranean diet principles, with adjustments to the Israeli dietary habits, focusing on the health advantages of the food and considering its processing level. The food products eligible for positive FOPL are foods in their natural form or with added spices or herbs, or those that underwent minimal processing, with no food additives. Based on population consumption data, 19.8% of food products were eligible for positive FOPL; of them, 54% were fruits and vegetables, 20% dairy, and 14% grains. An evaluation plan is needed to assess the degree of acceptance of the positive FOPL by the industry, retailers, and the public, and its impact on food consumption and on public health.

Improved meals service and reduced food waste and costs in medical institutions resulting from employment of a food service dietitian - a case study.

BACKGROUND: A recurring problem in medical institutions is patients not always receiving food meeting their nutritional and medical needs. A proposed contributing factor is non- inclusion of dietitians in food service staff. Recently, positions for food service dietitians in hospitals were created. For the newly defined role of "Food Service Dietitian", comprehensive training courses were developed (70 dietitians participated). OBJECTIVE: To examine the impact of the addition of the role of a "Food Service Dietitian" in medical institutions on suitability of foods served, food costs and food waste. METHODS: A three years (2014-2017) national case study to examine the new role's impact was carried out, in 18 hospitals, nine of which employ a food service dietitian (intervention), and 9 without (control). The number of nutritional analyses of menus was checked, as was the extent of kitchen staff training, and how often night meals were served for all patients. Data were gathered regarding food costs and waste with respect to food distributed to staff and patients. Food costs savings and waste reduction were calculated, based on reduction in provision of unnecessary meals, at a cost of 18 NIS per day per meal. RESULTS: Kitchen staff training was carried out in all intervention institutions, and not in the controls. In most controls, nutritional analyses were not performed, whereas in the intervention hospitals, full analyses were performed and tailoring of menus to specific department requirements improved significantly. In most intervention hospitals, late night snacks were provided, this not being so in the controls. Total food cost savings of $229,569 per annum was seen in the six intervention hospitals, attributable to 4 factors: 1.Meals not delivered to fasting patients, or those receiving parenteral/enteral nutrition- cost savings of 328,500 NIS ($93,857)2.Better tailoring and monitoring of food delivered to the wards and staff (bread, cheese, milk etc)- annual cost savings of 235,000 NIS ($67,142) in the hospitals with a food service dietitian.3.Checking expiry dates of medical foods, and improved communication between the wards, the kitchen and the food distribution centers, has lessened food waste with savings of 5% from the medical food budget per annum of 40,000 NIS ($11,428).4.As a result of dietitian-performed nutritional analyses, tailoring of food provided according to the patient's medical and nutrition needs was improved. In one hospital, after re-evaluation of serve sizes in high protein diets, sizes were reduced while retaining adequacy, with immediate cost savings of 200,000 NIS ($57,142) per annum. CONCLUSIONS: Implementation of the new role of Food Service Dietitian led to cost savings and significant improvements in adherence to the nutritional care plan.

The Relationships between Adolescents' Obesity and the Built Environment: Are They City Dependent?

There is evidence that the built environment can promote unhealthy habits which may increase the risk for obesity among adolescents. However, the majority of evidence is from North America, Europe and Australia, and less is known about other world regions. The purpose of this study was to examine how the number of overweight and obese adolescents may vary in relation to the built environment, area socioeconomic status (SES), physical activity (PA) and nutritional home environment. We performed a telephone survey of 904 adolescents ages 15-18 from three different cities in Israel. The questionnaire included: reported PA, sedentary behaviors and nutritional home environment. Body Mass Index (BMI) was attained from records of Maccabi Healthcare Services (MHS). The built environment measures were calculated by Geographic Information System (GIS). Multivariable logistic regression analysis was performed to identify variables associated with adolescents' overweight and obesity. The highest level of overweight and obese adolescents was in Beer Sheva (29.2%). The three cities did not differ in built environment characteristics, PA and sedentary behaviors. In Haifa, a more positive nutritional home environment was reported (p = 0.001). Boys, in all three cities presented higher rates of overweight and obesity (29%). After adjusting for covariates, adolescents' overweight and obesity was associated with built environment measures only in a low SES peripheral city (OR = 0.72; 95% CI: 0.56-0.92), and positively associated with higher level of sedentary behavior in the total sample (OR = 1.23; 95% CI:1.03-1.47). This may imply a much more complex causal pathway between the built environment, SES and obesity than suggested in previous literature.

Adaptation and predictive utility of a Mediterranean diet screener score.

BACKGROUND & AIMS: There is a substantial body of evidence supporting the health benefits of the Mediterranean diet, which has differing variations across the Mediterranean region. Abbreviated dietary screeners can be adapted and used to assess adherence to the local Mediterranean diet variant. We aimed to describe the process of adapting the Spanish Mediterranean Diet Adherence Screener (MEDAS) for use in Israel, and to test the predictive utility of the adapted score for mortality. METHODS: A professional committee of nutritional policy makers, dieticians and researchers adapted MEDAS to create an Israeli Mediterranean diet screener (I-MEDAS) that reflected the local Mediterranean diet and national dietary recommendations. The Hadera District Study (HDS) was a population-based, prospective cohort study of adults in Israel. Food frequency questionnaire (FFQ) data from the HDS was used to calculate Mediterranean diet adherence according to the I-MEDAS score criteria and evaluate the score's predictive utility. Mortality status was obtained from the national population registry. Cox proportional hazards regression models were used to test the predictive utility of the I-MEDAS score for all-cause mortality. RESULTS: The 14-item MEDAS was adapted to create a 17-item I-MEDAS. According to FFQ data from the HDS cohort (n = 1092 adults; median [IQR] follow-up time = 14 [12-15] years, 179 deaths), the median (IQR) I-MEDAS score was 8 (7-9). In multivariable analysis, every 1-point increase in the I-MEDAS score reduced the hazard of death by 12% (adjusted HR: 0.88; 95% CI: 0.80-0.97). The original MEDAS score was less strongly associated with mortality, and lost significance after adjustment for potential confounders. CONCLUSIONS: I-MEDAS reflects the local Mediterranean diet and national dietary recommendations in Israel. The I-MEDAS score, calculated from FFQ data, demonstrated predictive utility for mortality in a population-based cohort of adults.

Do Israeli health promoting schools contribute to students' healthy eating and physical activity habits?

The Israeli Health Promoting School Network (HPSN) is actively committed to enhancing a healthy lifestyle for the entire school population. This study aimed to explore the contribution of school participation in the HPSN and students' individual characteristics to healthy eating and physical activity habits among Israeli school children aged 10-12 years. A cross-sectional survey was conducted among 4166 students in grades 4-6 from 28 schools. The schools were selected from a sample of HPSN affiliated and non-HPSN schools. The contribution of individual characteristics (grade, gender and subjective self-reported health education activities at school) and school characteristics (school type, population group, deprivation score) to healthy eating and physical activity habits was analyzed using multi-level hierarchical models. Multi-level analysis indicated that student's individual characteristic was significantly associated with healthy eating and physical activity habits. The subjective self-reported health education received at school was statistically significant factor associated with students' health behaviors. The school's affiliation with the HPSN was not associated with higher healthy eating and physical activity scores after adjusting for individual factors. These findings suggest that Israeli HPSN schools do not contribute to children's health behaviors more than other schools. Therefore, health promoting activities in HPSN schools need to be improved to justify their recognition as members of the HPS network and to fulfill their mission.

Taxation of sugar sweetened beverages and unhealthy foods: a qualitative study of key opinion leaders' views.

BACKGROUND: Fiscal policies to fight obesity such as taxation of unhealthy foods or sugar-sweetened beverages (SSBs) have gained considerable attention in recent years. Many studies modelling the impact of various magnitudes of taxes on SSB purchasing and their potential effects on various health outcomes have been published; however, legislation and implementation of such taxes have encountered many obstacles in the countries that have implemented them to date. We investigated the perceptions and views of key opinion leaders, policy makers and various other Israeli stakeholders on taxation of SSBs and unhealthy snacks. We also evaluated the challenges and barriers that may be expected for initiating such a policy. METHODS: A qualitative study based on 39 in-depth interviews with Israeli stakeholders in the fields of health, nutrition, economics, public advocacy and policymaking. RESULTS: All stakeholders viewed obesity as a combined societal and personal issue that should be under government responsibility. Only stakeholders from economic sectors thought that taxation of SSBs and unhealthy snacks would reduce their consumption, while the prevailing notion among non-economists was that such a tax would not be acceptable because the higher price would not decrease consumption. Concerns were raised that the tax would mostly affect individuals from low socioeconomic backgrounds. Some of the stakeholders indicated that they would support such a tax only if its revenue would be directed to specific causes such as health-promoting plans. Potential barriers to taxation include: opposition of various sectors, technical and bureaucratic obstacles impeding tax implementation, difficulties in defining which products to tax, and opposition of the treasury to earmark tax revenue for health education. CONCLUSIONS: Taxation should be a part of a multipronged strategy rather than a sole measure for fighting obesity. Dedicating tax revenues to specific predefined causes should be considered, particularly towards health promotion activities, obesity treatment and prevention, education, and subsidies of healthy food.
