Nutritional quality of dietary patterns of children: are there differences inside and outside school?

Neophobia, sensory experience and child's schemata contribute to food choices

PURPOSE

The aim of the present review is to analyze dynamic interactions between nutrigenomics, environmental cues, and parental influence, which can all lead to children's neophobic reactions and its persistence in time.

METHODS

We reviewed studies available on electronic databases, conducted on children aged from birth to 18 years. We also considered official websites of Italian Institutions, providing advice on healthy eating during infancy.

RESULTS

Modern day societies are faced with an eating paradox, which has severe and ever-growing implications for health. In face of a wider availability of healthy foods, individuals instead often choose processed foods high in fat, salt and sugar content. Economic reasons surely influence consumers' access to foods. However, there is mounting evidence that food choices depend on the interplay between social learning and genetic predispositions (e.g., individual eating traits and food schemata). Neophobia, the behavioral avoidance of new foods, represents an interesting trait, which can significantly influence children's food refusal. Early sensory experiences and negative cognitive schemata, in the context of primary caregiver-child interactions, importantly contribute to the priming of children's food rejection.

CONCLUSIONS

As neophobia strongly affects consumption of healthy foods, it will be relevant to rule definitively out its role in the genesis of maladaptive food choices and weight status in longitudinal studies tracking to adulthood and, in meanwhile, implement early in life effective social learning strategies, to reduce long-term effects of neophobia on dietary patterns and weight status.

LEVEL OF EVIDENCE

Level II, controlled trials without randomization.

Transgenerational transmission of eating habits

OBJECTIVE

To investigate the relationship between the biopsychosocial environment and eating habits and behaviors that lead to the selection and consumption of certain food from the earliest stages of life. To clarify whether there is an interaction between genetic and epigenetic factors, and how they shape eating habits.

DATA SOURCE

A narrative review based on research in PubMed and Web of Science electronic databases was carried out over the last 10 years, searching the title and summary fields using the keywords Children OR adolescents Feeding Behavior eating OR Dietary Habits OR Eating Behavior OR Eating Habits OR Children obesity.

DATA SYNTHESIS

The generational transmission of eating habits is related to the home, community, and school environments, mainly during the first years of life, and can exert the modulation of habits during all stages of life. During childhood, the family's role in consolidating eating habits is very broad and ranges from choosing foods to prioritizing family meals, including the lifestyle.

CONCLUSIONS

Eating habits are transmitted from parents to children in different ways: environmental, emotional, social, and educational. In cases of obesity, a greater association of genetic influence can be observed.

Consumption of ultra-processed foods and associated factors in six-year-old children

This article aims to estimate the prevalence and weekly frequency of ultra-processed food consumption in six-year-old children and associated factors in a municipality in southern Brazil. Cross-sectional study with 956 children. Data were collected through interviews with mothers in the households. The outcomes were the consumption of candies, chewing gum, lollipops and chocolates; stuffed cookies; artificial juices; and soft drinks using the Índice de Alimentação Escolar (School Feeding Index). The independent variables were gender, type of school, education and maternal occupation, breastfeeding, duration of exclusive breastfeeding and the use of bottle. Bivariate analysis was performed using the chi-square test and the multivariate analysis using Poisson regression. In the multivariate analysis, the weekly prevalence of stuffed cookies consumption was 14% higher in students from public schools and 8% higher in children of mothers with less than eight years of schooling. Artificial juice and soft drink consumption was 7% and 8% higher in public school students respectively and 6% higher in bottle-fed children. Most schoolchildren consumed the ultra-processed foods assessed once or twice a week. Consumption was associated with the independent variables assessed.

Nutrient Intakes among Brazilian Children Need Improvement and Show Differences by Region and Socioeconomic Level

Brazil is the most populous country in South America. Using 24 h dietary data, we compared the nutrient intakes of 4–13-year-olds to reference values and tested for regional and socioeconomic (SES) differences. A considerable proportion reported intakes below the Estimated Average Requirements (EAR) for vitamins E (78.1%, 96.5%), D (100% for both), and calcium (80.5%, 97.7%) for 4–8 and 9–13-year-olds, respectively. Few exceeded Adequate Intakes (AI) for potassium or fiber. Older children reported greater inadequacies and, while there was regional variability, patterns of inadequacy and excess tended to be similar. For vitamin C, the percent of children below EAR in the Northeast and Southeast was lower than in the South. Most children, regardless of SES, had energy intakes within the Acceptable Macronutrient Distribution Ranges (AMDRs) for carbohydrates and protein. Over a quarter reported total energy from fat less than the AMDR, and inversely associated with SES (low 50.9%, moderate 26.0%, and high 15.0%), but also exceeding the percentage of energy recommendation for saturated fat, increasing with SES (low 18.1%, moderate 38.9%, and high 48.8%). The contrast observed between the diets of young Brazilians and recommendations underscores the need for individual and regional environmental interventions to promote healthier dietary patterns.

Low adherence to traditional dietary pattern and food preferences of low-income preschool children with food neophobia

OBJECTIVE

To associate dietary patterns and food neophobia in low-income preschoolers.

DESIGN

This was a cross-sectional study using a semi-structured questionnaire for socio-demographic data, birth conditions and breast-feeding history. Food neophobia was assessed using an adapted version of the Child Food Neophobia Scale. Children's nutritional status was assessed using BMI-for-age and height-for-age Z-scores. Dietary patterns were estimated using a semi-quantitative FFQ through exploratory factor analysis. Multiple linear regression was used to test for an association between food neophobia and dietary pattern adherence.

SETTING

Philanthropic childhood education schools in Aracaju, an urban community in northeastern Brazil, between July and December 2017.

PARTICIPANTS

Two hundred fourteen children aged 3-6 years and their parents.

RESULTS

The percentages of low/medium and high food neophobia among preschoolers were 85·9 % and 11·2 %, respectively. Children with high food neophobia more frequently consumed ultra-processed foods rich in sugars (snacks, filled and unfilled cookies and sweets), as well as protein-rich foods (white meat, cheese and yogurt). Three dietary patterns were identified (traditional, snacks and school snacks). Children with a high level of neophobia had lower adherence to traditional dietary patterns.

CONCLUSIONS

A high level of food neophobia among socially vulnerable preschoolers is an eating behaviour related to unhealthy eating and is associated with the poorest diet in typical foods.

Associated factors with dietary patterns among children under 2 years of age: a study in childcare centres and homes of South Brazil

Identifying dietary patterns in different environments attended by children is relevant to guide public politics. The aim of this study was to analyse the factors associated with dietary patterns of children under 2 years of age in childcare centres and at homes. This transversal study was enrolled in municipal childcare centres of Guaratuba, Paraná, Brazil. Food consumption data from 256 children were obtained by the food record method. From the consumption data, four dietary patterns were identified by factor analysis using the principal component method in each environment. ‘Traditional’ patterns were observed in both environments; the ‘less healthy’ pattern was found only at homes. Other patterns identified in childcare centres include ‘snacks’, ‘nutritive’ and ‘pasta and meats’; at homes, it was possible to identify patterns such as ‘milk and cereals’ and ‘mixed’. Children over 12 months presented higher scores for all the patterns in both environments. Obese children had lower scores for all the patterns in childcare centres. There was an association between maternal age below 21 years and higher adherence to a ‘less healthy’ pattern, maternal level of education less than 8 years and lower adherence to the ‘mixed’ pattern and lower familiar income per capita and higher adherence to the ‘snacks’ and ‘traditional’ patterns in childcare centres. In conclusion, adherence to dietary patterns was associated with socio-economic, demographic variables and nutritional status and further studies are needed, especially those with a longitudinal design, enabling the monitoring of dietary patterns.

Family influence on the nutritional status and eating habits of six to nine year-old children

ABSTRACT Objective To investigate whether caregivers’ attitudes, beliefs, practices, alimentary habits, and nutritional status influence the alimentary habits and nutritional status of children aged six to nine years. Methods This cross-sectional study included 164 children and a family member (caregiver) each (n=164), carried out in the family health units of the municipality of Ribeirão Preto (SP), Brazil. Weight and height measurements were performed; each child was then evaluated by the application of both the Child Feeding Questionnaire and 24h recall (for calculating the Healthy Eating Index Revised), in addition to the assessment of adherence to healthy eating steps of the Ministry of Health, through a questionnaire. Results The results showed that the prevalence of being overweight was 18.3% in children and 32.9% in caregivers, and the prevalence of obesity was 15.9% and 37.9%, respectively. Most of the 56 children categorized as overweight also had overweight caregivers (82.1%; n=46). Concerns regarding children’s weight control were higher among caregivers responsible for overweight children (3.6±1.29). In contrast, caregivers responsible for children below or at normal weight demonstrated a greater tendency toward getting children to eat (3.3±0.97 and 3.9±0.99, respectively). The average score; of the children’s Brazilian Healthy Eating Index Revised (50.0±13.6) was similar to that of their caregivers (56.5±12.1). Conclusions Caregivers have a direct influence on the nutritional status and eating habits of children; therefore, they should be targeted in the processes of nutritional intervention for the prevention and treatment of childhood obesity.

Identification of dietary patterns by principal component analysis in schoolchildren in the South of Brazil and associated factors

Abstract Objectives: to identify dietary patterns (DP) and associated factors in first grade school-children in elementary schools in the South of Brazil. Methods: school-based cross-sectional study, with a non-probabilistic sample of 782 schoolchildren aged 6 to 8. Food intake was assessed by a food frequency questionnaire. DP were identified using the principal component analysis and the prevalence ratios were obtained by Poisson regression with a robust variance. Results: four DP were identified and accounted for 25.3% of the total variance: "fruit, vegetables and fish" (8.5%), "sweets and salty snacks" (7.0%), "dairy, ham and biscuits" (5.0%) and "common Brazilian food" (4.8%). After the adjustment, breakfast habit and lower frequency of meals in front of a screen increased the probability of adherence to a high consumption of DP of "fruit, vegetables and fish". The maternal schooling level was linearly and inversely associated with DP of "sweets and salty snacks" and "common Brazilian food", and positively related to the DP of "dairy, ham and biscuits". Schoolchildren with food inse-curity and sufficiently active had higher probability of adherence to DP of "common Brazilian food". Conclusions: four DP were identified and associated with food insecurity, maternal socioeconomic characteristics and schoolchildren’s behavioral characteristics.

Dietary Patterns of Adolescents from the Chilean Growth and Obesity Cohort Study Indicate Poor Dietary Quality

Diet during adolescence can have lasting effects on nutritional status, health, and development. We hypothesized that dietary patterns with low-quality nutrition are associated with overweightness. We collected data for 882 Chilean adolescents from the Growth and Obesity Cohort Study (mean age: 12 years). Dietary intake was assessed through 24-h recalls and weight status data were obtained during clinical visits. Dietary patterns were obtained through exploratory factor analysis. Multiple logistic regression models were used to examine cross-sectional associations between dietary patterns and overweight (BMI z-score ≥ 1SD). Four dietary patterns were identified: "Breakfast/Light dinner", "Natural foods", "Western", and "Snacking". "Breakfast/Light dinner", "Western", and "Snacking" patterns provided higher energy and excess nutrients (sodium, saturated fat, and added sugar). Moreover, adolescents with higher adherence to "Western" or " Snacking" patterns (third tertile) had higher odds of being classified as overweight (OR = 1.67; 95%CI: 1.103-2.522 and OR = 1.86; 95%CI: 1.235-2.792, respectively) than those with lower adherence (first tertile). "Natural foods" pattern was also associated with overweightness (OR = 1.83; 95%CI: 1.219-2.754). These dietary patterns were associated with overconsumption of nutrients of public health concern. Three of the four main dietary patterns were associated with overweightness. These results highlight the need of prioritizing adolescents on obesity prevention strategies.

Brazilian Children's Dietary Intake in Relation to Brazil's New Nutrition Guidelines: a Systematic Review

PURPOSE OF REVIEW

This systematic review reports the latest scientific evidence, from cross-sectional and cohort studies, describing the dietary intake of children and adolescents from Brazil. The goal of the review was to describe intakes according to Brazil's new food classification system (NOVA) which classifies foods according to the degree of processing, i.e., unprocessed/minimally processed, processed culinary ingredients, processed food, and ultra-processed food. Due to a paucity of data using the NOVA classification system, studies with other intake descriptors were included.

RECENT FINDINGS

Results using the NOVA system showed a somewhat high intake of (ultra-)processed items, than of minimally processed items. Studies using other methods of dietary assessment showed not only high intake of sources rich in fat, sugar, and sodium, most of them processed items (e.g., savory snacks and sweets) but also intake of fruit, vegetables, and whole grains. Overall, the literature was marred by inconsistencies and variation in study definitions and methods making it hard to make firm conclusions regarding the dietary intake of Brazilian children. The development of tools to evaluate the complexities of dietary intake is much needed. Such a tool needs to be accepted and adopted by numerous study groups, to describe dietary status among Brazilian children and devise the most effective, and to evaluate the success of nutrition education programs.

Dietary Patterns and Childhood Obesity Risk: A Systematic Review

Background: Childhood overweight and obesity are recognized as predictors of the risk of obesity in adulthood. The aim of this systematic literature review was to determine the association between dietary pattern and obesity risk among children. Methods: Articles were selected from databases (Cochrane Library, Lilacs, Eric, Livivo, and PubMed/Medline), without limitations regarding language or date. Database-specific search terms included the key words "obesity," "diet," "dietary pattern," "childhood," "children," "adolescents," and relevant synonyms. The review included studies that reported the assessment of the dietary pattern in childhood and that correlated eating patterns with the obesity risk through cluster analysis (CA) and/or factor analysis and/or principal component analysis and presented odds ratios (ORs). The methodology of the selected studies was evaluated using the JBI Critical Appraisal Checklist for Analytical Cross-Sectional Studies. Owing to the heterogeneity among the assessments of the association of dietary patterns and obesity, the results are described narratively. Results: Using a selection process in two phases, 16 articles were included. Fifteen studies used a cross-sectional design, and one case-control study. The included studies showed variation in sample size (range = 232 to 10,187 children/adolescents) and age (range = 1-19 years old). The studies reported between two and five dietary patterns each. The OR for the relationship between the dietary pattern and the risk of childhood obesity ranged from OR = 1.02; confidence interval (95% CI) (0.91-1.15) to OR = 3.55; 95% CI (1.80-7.03). In this study, the dietary patterns identified by the studies were given different names. The food intake patterns identified could, in most factor or CA studies, be categorized as (1) potentially obesogenic foods that increased risk of becoming overweight (including fatty cheeses, sugary drinks, processed foods, fast food, candies, snacks, cakes, animal products, whole milk, and refined grains) or (2) food classified as healthy with the weakest association with the risk of becoming overweight or obese (including low levels of sugar and fat and high levels of fruits, vegetables, whole grains, fish, nuts, legumes, and yogurt). Conclusion: Overall, the results indicated from most studies that a diet with a lower percentage of obesogenic foods should be effective in reducing the risk of developing obesity.

Nutritional Status, Nutrient Intake, and Food Diversity Among Children With Sickle Cell Anemia

Children with sickle cell anemia (SCA) often exhibit nutritional deficiencies and are at high risk of dying before the age of 5 years. Ensuring adequate nutrition is a critical part of health care for such children. This study aimed to investigate the association between nutritional status, nutrient intake, and food diversity in children with SCA. A descriptive cross-sectional study was conducted on 74 children with SCA, between 24 and 71 months of age. Anthropometric measurements, food and nutrients consumption were determined. The prevalence of low weight, stunting, and overweight/obesity were 16.2%, 35.1%, and 16.2%, respectively. Mean folic acid intake was low (49.05%±51.22%), whereas the intakes of protein (426.71%±171.93%), retinol (292.97%±403.88%), phosphorus (204.55%±151.35%), magnesium (233.02%±151.14%), iron (250.76%±165.81%), and zinc (243.21%±148.40%) were high. The dietary phosphorus/protein ratio was high for 31.1% of the children, and 44.6% of the children had low dietary diversity score. No correlation was found between food diversity, nutrient adequacy, and nutritional status. Despite the adequacy of the intake of most micronutrients, diet quality was inadequate, constituting mainly ultraprocessed foods. Knowing the food consumption pattern of these children enables a more resolute nutritional intervention.

Padrões alimentares de adolescentes brasileiros por regiões geográficas: análise do Estudo de Riscos Cardiovasculares em Adolescentes (ERICA)

O estudo teve como objetivo identificar os padrões alimentares de adolescentes brasileiros para cada uma das cinco regiões do país, e verificar se há diferença na adesão dos padrões alimentares de acordo com idade, sexo e tipo de escola. Foram analisados dados de 71.298 adolescentes de 12 a 17 anos que participaram do Estudo de Riscos Cardiovasculares em Adolescentes (ERICA), pesquisa transversal, nacional, multicêntrica e de base escolar. Os dados de consumo alimentar foram obtidos por meio de recordatório alimentar de 24hs, e para a identificação dos padrões alimentares foi aplicada análise fatorial. A associação entre as características dos adolescentes e os padrões alimentares foi verificada por meio de análises de regressão linear, estratificadas por idade e ajustadas por estado nutricional, ingestão energética total e atividade física. Nas cinco regiões foram identificados três padrões alimentares com características similares: padrão tradicional, padrão pão e café e padrão não saudável. A Região Norte apresentou um quarto padrão alimentar caracterizado por alimentos típicos da região: padrão tradicional Norte. Em todas as regiões, os adolescentes do sexo masculino registraram maior adesão ao padrão tradicional e menor adesão ao padrão não saudável. entre os estudantes de escolas privadas foi observada maior adesão ao padrão não saudável e menor adesão ao padrão tradicional. Os resultados sugerem que, entre os adolescentes avaliados, ser do sexo masculino foi associado ao maior consumo de alimentos tradicionalmente brasileiros como o arroz e feijão, já o maior nível socioeconômico esteve associado ao consumo de alimentos não saudáveis como bebidas açucaradas e lanches.

Dietary Patterns of Children and Adolescents from High, Medium and Low Human Development Countries and Associated Socioeconomic Factors: A Systematic Review

The purpose of this systematic review is to assess the associations among education, income and dietary pattern (DP) in children and adolescents from high, medium and low human development countries (HHDC, MHDC and LHDC, respectively). Observational studies that evaluated the association between family income or education with the DP are obtained through electronic database searches. Forty articles are selected for review. In HHDC, education is inversely associated with "unhealthy" DP and positively associated with "healthy" DP. In cross-sectional studies from HHDC, higher income is negatively associated with "unhealthy" DP. In MHDC, there is no association between the socioeconomic variables (SE) and the DPs, although, in some studies, the unhealthy diet is positively associated with SE. Only one study conducted in LHDC showed an inverse association between income/education with "unhealthy" DP and there is no association between the SE and "healthy" DP. In conclusion, children and adolescents living in HHDC with high parental education tend to have a healthier diet. In MHDC, although an unhealthy diet is found among the high-income and educated population, the associations are not clear. Additional research is needed to clarify the associations between income and education with "unhealthy" and "healthy" DPs in MHDC and LHDC.
