Time to define food salt targets in Italy starting with cereal-based products: A safe and practical way to reduce the heavy burden of cardiovascular disease.

BACKGROUND AND AIMS: Excess salt intake is the leading dietary risk factor for cardiovascular disease in most countries, including Italy. While the cost-effectiveness of interventions aimed to reduce salt intake has been proved, the WHO recommendation to reduce salt intake by 30 % at the global level by 2025 is far from being reached. METHODS AND RESULTS: In Italy, two surveys of the general adult population have established that the average salt intake is still almost twice the WHO recommendation although it was reduced by 1.2 g/day between 2008-12 and 2018-19. Previous investigations had shown that non-discretionary salt added by the industry or by local craft producers represents at least 50 % of the total intake and indicated cereal-based products as the main source of non-discretionary salt. Two recent studies conducted by the Italian Society of Human Nutrition "Young Working Group" have provided updated information on the salt content of almost three thousand cereal-based products currently available on the Italian food market and shown that most of the items evaluated had a sodium content much higher than the sodium benchmarks recently proposed by WHO. CONCLUSIONS: Italy has built the foundations of an effective population strategy for salt intake reduction: it is time however to proceed with full commitment to food reformulation if any substantial further progress has to be made. Salt benchmarks for Italy need to be defined for the food categories most relevant to population salt intake and their implementation should ideally be mandatory after consultation with food producers.

Dietary assessment methods in surveillance systems targeted to adolescents: A review of the literature.

AIMS: The present paper aims to identify ongoing multinational surveillance systems (SURSYSs) assessing diet and nutrition targeted to adolescents, including European surveys involving multiple countries and similar initiatives conducted in non-European countries with developed economies, and to describe the dietary assessment methods used. DATA SYNTHESIS: A total of 13 SURSYSs conducted in Europe, USA, Canada, Australia and New Zealand were identified. Dietary assessment methods commonly used include 24-h recalls (24H-Rs) and questionnaires or interviews. Food frequency questionnaires (FFQs) are used in combination with 24H-Rs in six SURSYSs: only FFQs are used in four SURSYSs; 24H-Rs only in one system and a 24H-R in combination with a general questionnaire/interview in one SURSYS. Eleven systems collect information also on some dietary habits and ten systems on other nutritional indicators such as anthropometric and/or biochemical measures. The FFQs used are not homogeneous and often include limited food or beverage items such as fruits and vegetables or sugar-sweetened beverages. In seven systems, foods specifically consumed by adolescents, such as fast food or snacks, are not assessed; instead, a total of seven systems collect data on supplement intake and just in very few cases on fats, legumes and/or water. CONCLUSIONS: This study detected considerable variability across the systems identified, suggesting the need for a SURSYS targeted to adolescents that gathers as much as possible complete dietary information, with standardised methodology and regular periodicity. The detailed information provided by this review could be useful to national authorities for the choice of protocols to be applied in their own national surveys.

[Project of contrast to avoidable mortality in a metropolitan local health authority]. / Progetto di contrasto alla mortalità evitabile in una asl metropolitana.

INTRODUCTION: The avoidable mortality (ME)represents the share of deaths that occurs at an early age (0-74 aa) for causes that cannot be faced by means of public health or health care measures. The work develops a strategic intervention plan aimed at the reduction of ME by identifying local priority actions based on epidemiologic and social-health data. METHODS: a working group among the Department of Prevention, Health Information Systems and Health District was set up. The databases used were: "State of Health Lazio" of the Department of Epidemiology of the Lazio Region; ASL Roma 2 local health data on general mortality (2014-2016) and the local health profile of the surveillance systems "OKkio alla Salute", Passi and HBSC Lazio. The analysis results in an estimation of Asl Roma 2's data and in a comparison of this data set with the regional level of three indicators: avoidable mortality, prevalence and incidence of chronic diseases and lifestyle profile. RESULTS: in the three-year period (2014-2016) there were about 1,900 avoidable deaths per year; in the ASL Roma2 the ME represents about 16% of the total mortality and 60% of them are borne by the male sex. 51% of ME concerns cancer, 27% is linked to cardio-vascular diseases, 10% to trauma and poisoning. A preliminary comparison of standardized ASL Roma 2 rates of prevalence and incidence with regional values shows higher figures for some pathologies in ASL Roma 2: COPD prevalence (114 vs 107), breast neoplasia incidence (174 vs 153), incidence of lung neoplasia (71 vs 65). Prevalence and incidence of chronic diseases at the District level are not entirely consistent with the regional values according to a two level score. Incorrect lifestyles are widespread in at least 30% of the population and are more frequent in families with low educational level and with reported economic difficulties. CONCLUSIONS: despite the intrinsic limitations of a precise estimate of the data and the possible biases in a process of inference, the method has allowed to identify the priorities to assign in primary and secondary prevention interventions planning and for the improvement of health care; this analysis has been structured in a three years Local Strategic Plan to face the ME and was articulated in general and operational objectives and actions measured by indicators both process and, where possible, outcome evaluation.

From surveillance to development of nutritional guidelines.

In Italy, like in most parts of the world, 30% of children and almost 50% of adults are overweight. This condition is one of the causes of non-communicable diseases responsible for over two thirds of DALYs, deaths and costs for healthcare. Current surveys confirm that overweight and obesity are associated with food habits which have changed, in Italy, in the last fifty years. Fewer and fewer people have been following a Mediterranean diet, which is considered an effective diet for the prevention of many diseases. The consumption of fruit, vegetables, legumes, whole cereals, and EVO oil has decreased, while the consumption of food with high energetic density and rich in sugar, salt, and added fat has increased, especially when eating out. Schools and workplaces are the best places to promote healthy food habits and an active lifestyle. The aim is to involve families (including low-income families), educators, and catering services. This type of intervention is not new to the National Health System and has already led to improvements: however, it is still possible to improve the use of resources and coordination between social, educational, and health services bringing the community to become its own health promoter. Health operators have to be more aware of overweight as a health threat. The National Health Plan represents a commitment for Italy, the country hosting EXPO 2015, to fulfill the targets of the «Action Plan European Strategy for the Prevention and Control of Non-communicable Diseases 2012-2016¼ entrusting the Departments of Prevention with the interventions and development of a network of stakeholders.

Excess body weight and incidence of stroke: meta-analysis of prospective studies with 2 million participants.

BACKGROUND AND PURPOSE: A systematic review of the prospective studies addressing the relationship of overweight and obesity to major stroke subtypes is lacking. We evaluated the occurrence of a graded association between overweight, obesity, and incidence of ischemic and hemorrhagic stroke by a meta-analysis of cohort studies. METHODS: A search of online databases and relevant reviews was performed. Inclusion criteria were original article in English, prospective study design, follow-up > or = 4 years, indication of number of subjects exposed, and number of events across body mass index categories. Crude unadjusted relative risk (RR) and 95% CI were calculated for each study for overweight or obese compared with normal-weight categories. Log-transformed values and SE were used to calculate the pooled RR with random effects models; publication bias was checked. Additional analyses were performed using the multivariate estimates of risk reported in the individual studies. RESULTS: Twenty-five studies were included, with 2 274 961 participants and 30 757 events. RR for ischemic stroke was 1.22 (95% CI, 1.05-1.41) for overweight and 1.64 (95% CI, 1.36-1.99) for obesity, whereas RR for hemorrhagic stroke was 1.01 (95% CI, 0.88-1.17) and 1.24 (95% CI, 0.99-1.54), respectively. Subgroup and meta-regression analyses ruled out gender, population average age, body mass index and blood pressure, year of recruitment, year of study publication, and length of follow-up as significant sources of heterogeneity. The additional analyses relying on the published multivariate estimates of risk provided qualitatively similar results. CONCLUSIONS: Overweight and obesity are associated with progressively increasing risk of ischemic stroke, at least in part, independently from age, lifestyle, and other cardiovascular risk factors.

Salt and Health: Survey on Knowledge and Salt Intake Related Behaviour in Italy.

BACKGROUND AND AIM: Excess sodium intake is a recognised causal factor of hypertension and its cardiovascular complications; there is however a lack of practical instruments to assess and monitor the level of knowledge and behaviour about dietary salt intake and to relate these factors to the population general dietary habits. METHODS AND RESULTS: A self-administered questionnaire was developed to assess the salt and health related knowledge and behaviour of the Italian population through an online survey. A sample of 11,618 Italian participants completed the questionnaire. The degree of knowledge and the reported behaviour about salt intake were both found to be related to age, gender, home region, level of education and occupation. There was a significant interrelation between salt knowledge and behaviour and both were significantly and directly related to the degree of adherence to a Mediterranean-like dietary pattern. A hierarchical evaluation was also made of the relevance of any single question to the overall assessment of knowledge and behaviour about salt intake. CONCLUSIONS: The study population overall appeared to have a decent level of knowledge about salt, but a less satisfactory behaviour. Our findings point to social inequalities and young age as the main factors having a negative impact on knowledge and behaviour about salt intake as part of generally inadequate dietary habits. The degrees of knowledge and behaviour were significantly and directly interrelated, confirming that improving knowledge is a key step for behavioural changes, and suggesting that educational campaigns are crucial for the implementation of good practices in nutrition.

The Domains of Human Nutrition: The Importance of Nutrition Education in Academia and Medical Schools.

Human nutrition encompasses an extremely broad range of medical, social, commercial, and ethical domains and thus represents a wide, interdisciplinary scientific and cultural discipline. The high prevalence of both disease-related malnutrition and overweight/obesity represents an important risk factor for disease burden and mortality worldwide. It is the opinion of Federation of the Italian Nutrition Societies (FeSIN) that these two sides of the same coin, with their sociocultural background, are related to a low "nutritional culture" secondary, at least in part, to an insufficient academic training for health-care professionals (HCPs). Therefore, FeSIN created a study group, composed of delegates of all the federated societies and representing the different HCPs involved in human nutrition, with the aim of identifying and defining the domains of human nutrition in the attempt to more clearly define the cultural identity of human nutrition in an academically and professionally oriented perspective and to report the conclusions in a position paper. Three main domains of human nutrition, namely, basic nutrition, applied nutrition, and clinical nutrition, were identified. FeSIN has examined the areas of knowledge pertinent to human nutrition. Thirty-two items were identified, attributed to one or more of the three domains and ranked considering their diverse importance for academic training in the different domains of human nutrition. Finally, the study group proposed the attribution of the different areas of knowledge to the degree courses where training in human nutrition is deemed necessary (e.g., schools of medicine, biology, nursing, etc.). It is conceivable that, in the near future, a better integration of the professionals involved in the field of human nutrition will eventually occur based on the progressive consolidation of knowledge, competence, and skills in the different areas and domains of this discipline.

Dietary habits among children aged 8-9 years in Italy.

OBJECTIVE: To describe dietary habits and related geographic and socio-demographic characteristics among children aged 8-9 years in Italy. MATERIALS AND METHODS: Data from the 2012 national nutritional surveillance system collected from children, parents and teachers, have been linked to determine the children's eating habits. Logistic regression analyses were used to investigate the association between incorrect dietary habits and their potential predictors. RESULTS: Of the 46 307 children, 8.6% skipped breakfast, 48.8% did not eat vegetables and 28.7% did not eat fruit daily, 64.8% ate an abundant mid-morning snack, 41.4% drank sugary beverages and 12.5% drank carbonated beverages at least once a day. Three or more incorrect habits were found in 43.9% of the children. Incorrect dietary habits were more common among children with lower socio-economic conditions, who were resident in the South of the country and who spent more time watching TV. CONCLUSION: In Italy, unhealthy dietary habits are common among children. The deficiencies identified may well be a harbinger of future public health problems.

Recommending salt intake reduction to the hypertensive patient: more than just lip service.

The average individual dietary salt intake largely exceeds the physiological needs almost worldwide. A direct causal association between salt intake and blood pressure levels has been clearly established. Furthermore, there is increasing evidence for additional blood pressure-independent pathways linking excess salt intake to the process of atherosclerosis. Recent meta-analyses of randomized controlled trials showed that moderate reduction of salt intake is associated with reduction of blood pressure and, in perspective, with reduction of cardiovascular and cerebrovascular events in hypertensive individuals. According to the European Society of Hypertension/European Society of Cardiology (ESH/ESC) guidelines for the management of hypertension, instructions to reduce dietary salt intake to the level of 5 g/day based on the WHO recommendation should be provided to all patients, regardless of their requirement for drug treatment. Unfortunately, the patients' response to this measure is heterogeneous, mainly due to variable compliance with the doctor's prescription and to a lesser extent to different individual BP salt sensitivity. This article discusses the factors affecting the probability of a successful intervention focusing in particular on the doctor's commitment to evaluate the patient's dietary habits, to point out the main sources of salt in the patient's diet, to provide the patient with adequate motivation and with proper instructions to implement gradual reduction of his/her salt intake, not disregarding the need for regular follow-up.

Dietary intake and physical activity of normal weight and overweight/obese adolescents.

Purpose. To evaluate the relationship between overweight/obesity and dietary/lifestyle factors among Italian adolescents. Methods. On a total of 756 adolescents with mean age 12.4 +/- 0.9, body mass index, food consumption, and time dedicated to after school physical activities and to TV viewing were determined. The data were analysed according to age, nutritional status, and gender. The analysis of variance and multiple logistic regression analysis were performed to investigate the association between dietary/lifestyle factors and overweight/obesity. Results. The percentages of overweight and obesity were, respectively, 28% and 9% among boys, 24% and 7% among girls. The overweight/obesity condition in both genders was associated with parental overweight/obesity (P < .001 for mother), less time devoted to physical activity (P < .001 for boys and P < .02 for girls) and being on a diet (P < .001). Direct associations were also observed between BMI and skipping breakfast and the lower number of meals a day (boys only). Conclusions. This pilot study reveals some important dietary and lifestyle behaviour trends among adolescents that assist with identification of specific preventive health actions.
