Food advertising during children's television programmes in Italy.

OBJECTIVE: Previous studies from European countries noted that food products promoted on TV for children did not comply with international guidelines, including the World Health Organization European Nutrient Profile Model (WHO-ENPM) and the EU Pledge Nutrition Criteria (EU-PNC, an initiative developed by leading food companies). We aim to provide new data from Italy. DESIGN: Evaluation of Italian TV advertisements. Data on nutritional values for food product advertised were compared with nutritional standards issued by the WHO-ENPM and the EU-PNC. SETTING: In total, 180 h of TV programmes from six Italian channels, 2016-2017. PARTICIPANTS: Eight hundred and ten consecutive advertisements during children's programmes. RESULTS: Out of 810 advertisements, 90 (11·1 %) referred to food products. Among these, 84·5 % of the foods promoted did not meet the WHO-ENPM and 55·6 % the EU-PNC guidelines. Advertisements promoting sweet and salty snacks (i.e. ≥ 70 % of all foods) v. other food products showed higher non-compliance with both the WHO-ENPM (OR: 73·8; 95 % CI: 4·09, 1330) and the EU-PNC (OR: 9·21; 95 % CI: 2·82, 30·1). CONCLUSIONS: In Italy, most food advertisements during children's programmes are not compliant with European nutritional standards. Almost all the advertisements for snacks do not meet international guidelines. As the WHO-ENPM guidelines do not propose standards for all the food products, including meals, there is an urgent need to define independent and easy-to-read guidelines for food advertisements targeting children. As a first step towards the complete ban of food advertisements targeting children recommended by other researchers, these guidelines should be enforced by all the TV broadcasts.

Nutrient intake in aging infants and toddlers: 3-year follow-up of the Nutrintake study.

We performed a 3-year follow-up of the children enrolled into the Nutrintake Study to evaluate the changes of anthropometry and nutrient intake in aging infants and toddlers. Nutrient intake was assessed using a 7-day weighted food-diary. Of the 390 Nutrintake children, 164 (42%) participated in the present study. Their median (IQR) age was 54 (48; 66) months and their anthropometrical status, expressed as standard deviation scores, remained stable during the follow-up. During the same period, there was no biologically relevant change in the intake of macronutrients expressed as percentage of energy while median increases of 757 mg/day, 0.7 mg/day and 3.1 g/1000 kcal per day were detected for sodium, iron and fibre, respectively. As compared to the Italian reference standards, the Nutrintake children continued to show at the 3-year follow-up an excessive intake of simple carbohydrates, proteins, sodium, and a low intake of iron and fibre.

Snacking in nutrition and health.

Many studies suggest that distributing energy and nutrient intake across 4-5 eating occasions/day (rather than across three standard meals) could favourably affect human health. The inclusion of 1-2 snacks in the daily pattern alleviates the potential digestive and metabolic overload caused by fewer heavier meals and might contribute to meet recommendations for food groups (e.g. fruits, dairy) and nutrients like fibre and vitamins. The snack composition should be evaluated taking into account the whole day's diet. In early and late ages, and for specific population groups, snacking may need to follow particular characteristics in order to be optimal, both in terms of composition and timing. This document, which is the result of a collaboration of experts across several fields of research, intends to provide a review of the current scientific literature on meal frequency and health, highlighting the beneficial effects of correct snack consumption across the human lifespan.

Associations between Dietary Intake, Blood Levels of Omega-3 and Omega-6 Fatty Acids and Reading Abilities in Children.

Lower levels of omega-3 polyunsaturated fatty acids (PUFAs) have been described in individuals with reading difficulties, but the degree and the nature of such deficiencies as well as the role of nutrition are a matter of debate. The aim of the present study was to investigate the associations between PUFA blood levels, nutritional status, and reading/writing/phonological awareness performances in 42 school-age children with varying levels of reading ability. Significant correlations were found between PUFA levels (specific omega-6/omega-3 ratios), the ratio of omega-6-derived calories to the total amount of calories and reading scores. Mediation analysis showed a mediating effect of fatty acids on the association between reading speed scores and nutritional status. Moderation analysis, moreover, showed that the associations of omega-6/omega-3 ratios in the blood and Kcal omega-6/Kcal total in dietary intake were moderated by reading speed performances. Results of the mediation and moderation models confirm that the associations of dietary intake with PUFA levels in the blood vary depending on learning abilities. Reading skills appear to be sensitive to the effects of a complex set of favorable conditions related to the presence of higher omega-3 blood levels. These conditions may reflect the action of dietary as well as genetic and epigenetic mechanisms.

Prevalence and Correlates of Overweight, Obesity and Physical Activity in Italian Children and Adolescents from Lombardy, Italy.

Investigating pediatric overweight and physical activity correlates is essential to design effective preventive programs. We used regional data (Lombardy, northern Italy) from the 2019 survey "OKKio alla Salute" (3093 children aged 8-9 years with measured anthropometric data), and from the 2018 wave of the "Health Behaviour in School-aged Children" survey (2916 adolescents aged 11-15 years with self-reported anthropometric data). In both the surveys, a cluster sampling methodology was used. Unconditional multiple logistic regression models were applied to estimate the odds ratios (OR) and corresponding 95% confidence intervals (CI) of overweight, obesity and poor physical activity. The prevalence of overweight (including obesity) was 22.4% for children aged 8-9 years and 14.4% for adolescents aged 11-15 years. A higher prevalence of overweight was observed among males, children with greater birth weight and those with obese parents. Scant physical activity was higher among females and older adolescents. There was a direct relationship between obesity and increased psychological distress (OR = 2.44; 95% CI: 1.12-5.27) or being victims of bullying (OR = 2.25; 95% CI: 1.17-4.34). Increasing physical activity significantly decreased the frequency of mental health outcomes. Prevention campaigns should be promoted to safeguard childhood physical and psychological wellbeing.

Effect of Vitamin D and Docosahexaenoic Acid Co-Supplementation on Vitamin D Status, Body Composition, and Metabolic Markers in Obese Children: A Randomized, Double Blind, Controlled Study.

Obese children are at high risk of developing vitamin D deficiency. Omega-3 polyunsaturated fatty acids and their derivatives might have a beneficial effect on vitamin D status of obese children, due to their anti-inflammatory action, and increasing its absorption. This multicenter, randomized, double-blind controlled study aims to investigate the effect of vitamin D and docosahexaenoic acid (DHA) co-supplementation for six months on vitamin D status, body composition, and metabolic markers of obese children with vitamin D deficiency. A total of 108 children were enrolled and 73 children completed the study: 33 were supplemented with an oral dose of 500 mg of DHA and 1200 IU/day of vitamin D3 and 41 were supplemented with 1200 IU/day of vitamin D3 + wheat germ oil. At the end of the study, more than 50% of the subjects improved their vitamin D status. However, co-supplementation was not more effective than vitamin D plus wheat germ oil. Fat mass percentage was significantly reduced, and body mass index improved in both groups, even if all the subjects were still obese at the end of the study. Children receiving both vitamin D and DHA presented a higher increase of DHA levels that could be relevant to prevent inflammatory-associated complications of obesity, but they had no effect on vitamin D levels.

Prevalence and Correlates of Overweight and Obesity in 12 European Countries in 2017-2018.

INTRODUCTION: Using data from the TackSHS survey, we aim to provide updated estimates on the prevalence and determinants of overweight and obesity in Europe. METHODS: A face-to-face survey was conducted in 2017-2018 in 12 European countries (Bulgaria, England, France, Germany, Greece, Ireland, Italy, Latvia, Poland, Portugal, Romania, and Spain). Overall, 10,810 participants, representative in each country of the general adult population, provided information on self-reported height and weight. RESULTS: Almost half of participants (48.1%; 95% confidence interval, CI: 47.2-49.1) reported to be overweight or obese (54.1% in men and 42.5% in women) and 12.6% (95% CI: 12.0-13.2) obese (11.3% in men and 13.8% in women). Obesity prevalence was lowest in Italy (7.5%) and France (8.8%) and highest in Greece (19.7%) and Romania (21.1%). Multilevel logistic random-effects analyses showed that prevalence of obesity was related with higher age and lower level of education and socioeconomic status. As compared to northern European countries, Western and Southern European ones showed a significantly lower obesity prevalence. When compared to a companion study conducted in 2010, Eastern and Northern European countries showed an increased trend in obesity prevalence. Conversely, countries with the lowest obesity prevalence (less than 10%), such as Italy and France, showed a decreased trend. CONCLUSIONS: Despite a large heterogeneity across countries, overweight and obesity prevalence estimates in Europe are alarming, with most of the countries reporting obesity prevalence approaching 20% or more, particularly in Eastern and Northern Europe. Since 2010, obesity prevalence increased in most of these countries.

Understanding feeding problems in autistic children: Exploring the interplay between internalizing symptoms and sensory features.

LAY ABSTRACT: This study adds to a growing body of research documenting feeding problems in autistic children. Our results indicate that children aged 1.5-5 years with feeding problems may present with elevated internalizing difficulties and alterations in sensory processing when compared to same-age children without feeding problems. Our study also proposes that sensory processing may be an important, mediating factor in the relationship between autism features and feeding problems. The present work suggests, therefore, that implementers should thoroughly consider the sensory profile of autistic children prior to intervening on feeding behaviors. In particular, based on these preliminary findings, feeding interventions could benefit from environments designed to support children who can find them noisy and overwhelming.

Methodology for longitudinal assessment of nutrient intake and dietary habits in early childhood in a transnational multicenter study.

OBJECTIVES: The aim of this study was to describe developed methods for repeated longitudinal assessment of feeding habits and nutrient intakes of children in a multicenter trial in different European countries and to assess feasibility. PATIENTS AND METHODS: Nutrient intake and dietary habits of formula-fed and breast-fed infants were assessed in 5 European countries (Belgium, Germany, Italy, Poland, and Spain). Prospective age-adapted 3-day weighed food records were used from birth to 2 years of age (1, 2, 3, 4, 5, 6, 7, 8, 9, 12, 18, and 24 months). Standard operating procedures were developed to check each day's food record for quality. Dietitians were trained by using standardized food records. Data entry and nutrient analyses were performed with a dedicated software developed for this project. RESULTS: Of 1368 study participants, at least one 3-day food record was available; of 25,367 1-day food records, data on quality could be evaluated. Overall, between 81% and 97% (depending on the country) of the food records had been completed with high accuracy. The implementation of solid foods and regular family foods decreased the recording quality significantly during the 2-year time course (P < 0.001). The standardized training shows coefficients of variation up to a maximum of about 41%, indicating differences in data entry. CONCLUSIONS: The experiences gathered indicate that collecting dietary and behavioral data in a large number of infants from different cultures is a challenging but feasible task in which permanent supervision and training is vital. However, we conclude that the established methodology is suitable to obtain valuable results on current infant nutrition practice in Europe.

Introduction of potentially allergenic foods in the infant's diet during the first year of life in five European countries.

BACKGROUND: Little information is available on infants' age at first introduction of potentially allergenic foods as part of complementary feeding. We aimed to analyze age at the introduction of potentially allergenic foods in healthy term infants relative to recommendations in 5 European countries. METHOD: Recruitment was conducted from October 2002 to June 2004. A total of 1,678 infants [588 breastfed (BF) and 1,090 formula-fed (FF) infants] were studied. In 1,368 infants, at least one 3-day weighed food diary at the age of 1-9 and 12 completed months was available. RESULTS: Six percent of BF infants and 13% of FF infants consumed some potentially allergenic food already prior to the recommended minimum age of 4 months, and 4% of BF infants and 11% of FF infants had already received gluten. There were significant differences in the timing of the introduction of potentially allergenic foods between the countries at the age of 4-6 months (p < 0.001). CONCLUSION: The time of first introduction of potentially allergenic foods in infants differed significantly between countries, and they were introduced much earlier than recommended in some countries. FF infants received potentially allergenic foods earlier than BF infants. Better information and counseling of parents is desirable.

Towards a More Sustainable Nutrition: Complementary Feeding and Early Taste Experiences as a Basis for Future Food Choices.

The concept of sustainable nutrition considers different fields: from human health to environmental, economic and socio-cultural aspects. Currently, in Europe, the diets that reflect the assumptions of the sustainable diet are the Mediterranean Diet and the New Nordic Diet. They both encourage the consumption of vegetable, organic and minimally processed foods, as well as regional, seasonal and Fair-Trade products, reducing the ecological impact of the production chain. These eating habits could be established starting from the prenatal period and from infancy during the complementary feeding stage, aiding children to accept of a more variable diet in terms of flavor, taste and texture. In particular, the positive parental role model is an effective method for improving a child's diet and behaviors. Two healthy plates representing a sustainable diet in early infancy, at 6 and 24 months, are here proposed, in line with the "Planetary Health Diet" approved by the EAT-Lancet Commission. Our work aims to highlight how a sustainable diet is possible since infancy, since the introduction of solid foods.

Liver fat change in obese children after a 1-year nutrition-behavior intervention.

OBJECTIVES: To evaluate whether a 1-year nutrition-behavior intervention based on normocaloric balanced diet and physical exercise may reduce liver fat in obese children. PATIENTS AND METHODS: Twenty-six obese children (11 boys and 15 girls), aged 6 to 14 years, underwent anthropometric, nutritional, metabolic, and liver magnetic resonance imaging (MRI) examinations at baseline and after a 1-year nutrition-behavior intervention. Anthropometry included weight, height, waist and hip circumference, and total upper arm area. Body mass index z scores were calculated. Biochemistry included serum aminotransferases, lipid profile, glucose, and insulin. Liver steatosis was judged as hepatic fat fraction (FF) by MRI and was > or =9%. RESULTS: Prevalence of steatosis was 34.6% at baseline and declined to 7.7% after intervention (P < 0.0001). Mean (95% CI) reduction of liver FF was 8.0% (4.0%-12.0%). In 77.8% of children with liver steatosis at baseline, the FF declined lower than 9% at the end of intervention, going from a mean (SD) of 18.7% (9.1) to 1.3% (4.1), (P < 0.0001). At the end of the intervention, children showed a mean reduction in body mass index z score of 0.26 (0.11-0.41) and waist circumference of 1.46 (0.34-2.60) cm. Triglycerides, total cholesterol, apolipoprotein A1, apolipoprotein B, ApoA1/ApoB ratio, and gamma-glutamyltransferase plasma values in plasma decreased at the end of intervention (P < 0.05). CONCLUSIONS: The results suggest that in obese children nutritional-behavior interventions may reduce the liver fat.

Introduction of complementary feeding in 5 European countries.

OBJECTIVES: Little is known about the practice of introducing complementary feeding across Europe. We aim at describing times of solid introduction in healthy infants in 5 European countries. MATERIALS AND METHODS: Between October 2002 and June 2004, 1678 healthy term infants were either breast-fed (BF) for at least 4 months (n = 588) or study formula-fed (FF) (n = 1090) with different protein contents. Three-day-weighed food protocols were obtained at ages 1, 2, 3, 4, 5, 6, 7, 8, 9, and 12 completed months. RESULTS: Solids were introduced earlier in FF infants (median 19 weeks, interquartile range 17-21) than BF infants (median 21 weeks, interquartile range 19-24). Some 37.2% of FF infants and 17.2% of BF infants received solid foods at 4 completed months, which is earlier than recommended in Europe. Solids had been introduced at 7 completed months in 99.3% of FF infants and 97.7% of BF infants, respectively. Belgium had the highest percentage of solids feeding in FF infants at 3 (15.8%) and 4 (55.6%) completed months, and in BF infants at 4 (43%) and 5 (84.8%) completed months. Multiple regression showed low maternal age, low education level, and maternal smoking to predictors an early introduction of solids at 3 and 4 completed months. CONCLUSIONS: Complementary feeding is introduced earlier than recommended in a sizeable number of infants, particularly among FF infants. Country- and population-specific approaches to adequately inform parents should be explored.

Prediction of Resting Energy Expenditure in Children: May Artificial Neural Networks Improve Our Accuracy?

The inaccuracy of resting energy expenditure (REE) prediction formulae to calculate energy metabolism in children may lead to either under- or overestimated real caloric needs with clinical consequences. The aim of this paper was to apply artificial neural networks algorithms (ANNs) to REE prediction. We enrolled 561 healthy children (2-17 years). Nutritional status was classified according to World Health Organization (WHO) criteria, and 113 were obese. REE was measured using indirect calorimetry and estimated with WHO, Harris-Benedict, Schofield, and Oxford formulae. The ANNs considered specific anthropometric data to model REE. The mean absolute error (mean ± SD) of the prediction was 95.8 ± 80.8 and was strongly correlated with REE values (R2 = 0.88). The performance of ANNs was higher in the subgroup of obese children (101 ± 91.8) with a lower grade of imprecision (5.4%). ANNs as a novel approach may give valuable information regarding energy requirements and weight management in children.

The relationship of insulin resistance with SNP 276G>T at adiponectin gene and plasma long-chain polyunsaturated fatty acids in obese children.

This study examined the association of insulin resistance with single-nucleotide polymorphism (SNP) 276G>T at adiponectin gene and the plasma long-chain polyunsaturated fatty acids (LCPUFAs) profile in obese children. One hundred thirty-one normolipidaemic obese children aged 8-13 y (53 girls and 68 boys) entered the study. The prevalence of T allele carriers at SNP276 was 48.8%. Mean [SD] values of fasting insulin and homeostasis model assessment-insulin resistance (HOMA-IR) index in noncarriers versus carriers of T allele were 12.4 [6.4] versus 20.6 [6.3] muU/mL (p = 0.039) and 2.6 [1.4] versus 4.5 [1.7] (p = 0.032). Mean [SD] values of plasma C18:3n - 3, C20:5n - 3/C20:4n - 6, and n - 6/n - 3 LCPUFA in phospholipids in noncarriers versus carriers of T allele were 0.10 [0.04] versus 0.08 [0.03] % (p = 0.013), 0.04 [0.01] versus 0.03 [0.01] % (p = 0.045), and 4.4 [0.7] versus 4.9 [0.9] % (p = 0.005), respectively. Insulin resistance was independently associated with SNP 276G>T (p = 0.002) and n - 6/n - 3 LCPUFA (p = 0.042) in plasma phospholipids, and interaction was found between SNP 276G>T and n - 6/n - 3 LCPUFA (p = 0.046). These findings suggest that obese children carriers of the SNP 276G>T may be at increased risk of metabolic complications compared with noncarriers, possibly due in part to a different plasma phospholipids profile.

Infant feeding and later obesity risk.

Some 30 years ago, Günter Dörner proposed that exposure to hormones, metabolites and neurotransmitters during limited, sensitive periods of early development exert programming effects on disease risk in human adults. Early programming of long term health has since received broad scientific support and attention. For example, evidence increases for programming effects of infant feeding choices on later obesity risk. Meta-analyses of observational studies indicate that breast feeding reduces the odds ratio for obesity at school age by about 20%, relative to formula feeding, even after adjustment for biological and sociodemographic confounding variables. We hypothesized that breast feeding protects against later obesity by reducing the likelihood of high weight gain in infancy, and that this protection is caused at least partly by the lower protein supply with breast milk relative to standard infant formulae (the "Early Protein Hypothesis"). These hypotheses are tested in the European Childhood Obesity Project, a randomized double blind intervention trial in more than 1,000 infants in five European countries (Belgium, Germany, Italy, Poland, Spain). Formula fed infants were randomized to receive during the first year of life infant formulae and follow-on-formulae with higher or lower protein contents. Follow-up at 2 years of age shows that lower protein supply with formula normalizes early growth relative to a breast fed reference group and to the WHO growth reference. These results demonstrate that modification of infant feeding practice has an important potential for long-term health promotion and should prompt a review of the recommendations and policies for infant formula composition.

MRI in identifying hepatic steatosis in obese children and relation to ultrasonography and metabolic findings.

OBJECTIVES: The aim of this study was to identify nonalcoholic fatty liver in obese children by magnetic resonance imaging (MRI) and to compare the findings with the data from ultrasonography and from clinical and laboratory testing. PATIENTS AND METHODS: Sixty obese children, 6 to 14 years old, underwent hepatic MRI and abdominal ultrasonography. Biochemistry determinations included serum aminotransferases, lipid profile, glucose, and insulin. Anthropometry included body mass index, total and trunk fat, and fat-free mass obtained by dual-energy radiographic absorptiometry. Hepatic steatosis, judged as hepatic fat fraction by MRI, was >or=9%. RESULTS: By MRI, 14 (23%) children had hepatic steatosis; of those, 5 had a fat fraction of 9% to 18%, and 9 had a fat fraction >18%. At univariate analysis, fat fraction was positively associated with being male, serum alanine aminotransferase, aspartate aminotransferase, and gamma-glutamyltransferase, body mass index z score, insulin, systolic pressure, and total and trunk fat mass. Hepatic steatosis was independently associated with alanine aminotransferase (P < 0.01). Overall, liver echogenicity on ultrasonography correlated well with fat fraction by MRI (correlation coefficient 0.527, P < 0.0001). Among the 27 children with increased liver echogenicity, 13 (48%) had hepatic fat fraction >or=9%, and 89% of children with echogenicity graded 2 or 3 had fat fraction >18%. All of the children (n = 9) with fat fraction >18% had increased liver echogenicity, and in 8 of them it was graded 2 or 3, but the MRI fat fraction ranged greatly (28%-45%). CONCLUSIONS: In obese children, nonalcoholic hepatic steatosis may be associated with the metabolic syndrome. Ultrasonography may be valuable in identifying high hepatic fat accumulation, but its ability to identify lower fat accumulation in the liver is scanty compared with MRI.

Factors Influencing Children's Eating Behaviours.

Relevant factors involved in the creation of some children's food preferences and eating behaviours have been examined in order to highlight the topic and give paediatricians practical instruments to understand the background behind eating behaviour and to manage children's nutrition for preventive purposes. Electronic databases were searched to locate and appraise relevant studies. We carried out a search to identify papers published in English on factors that influence children's feeding behaviours. The family system that surrounds a child's domestic life will have an active role in establishing and promoting behaviours that will persist throughout his or her life. Early-life experiences with various tastes and flavours have a role in promoting healthy eating in future life. The nature of a narrative review makes it difficult to integrate complex interactions when large sets of studies are involved. In the current analysis, parental food habits and feeding strategies are the most dominant determinants of a child's eating behaviour and food choices. Parents should expose their offspring to a range of good food choices while acting as positive role models. Prevention programmes should be addressed to them, taking into account socioeconomic aspects and education.

Early Taste Experiences and Later Food Choices.

BACKGROUND: Nutrition in early life is increasingly considered to be an important factor influencing later health. Food preferences are formed in infancy, are tracked into childhood and beyond, and complementary feeding practices are crucial to prevent obesity later in life. METHODS: Through a literature search strategy, we have investigated the role of breastfeeding, of complementary feeding, and the parental and sociocultural factors which contribute to set food preferences early in life. RESULTS: Children are predisposed to prefer high-energy, -sugar, and -salt foods, and in pre-school age to reject new foods (food neophobia). While genetically determined individual differences exist, repeated offering of foods can modify innate preferences. CONCLUSIONS: Starting in the prenatal period, a varied exposure through amniotic fluid and repeated experiences with novel flavors during breastfeeding and complementary feeding increase children's willingness to try new foods within a positive social environment.
