Objective: The aim of the current study is to analyze the associations between breakfast consumption and adherence to diet quality index (DQI) and Mediterranean Diet Score (MDS) in European adolescents.
Methods: A multinational cross-sectional study was carried out in 1804 adolescents aged 12.5-17.
One of the current main public health problems is the prevalence of obesity in children. Unhealthy lifestyle behaviors such as poor dietary habits, high sedentary screen time (SST), and low levels of physical activity (PA) have a strong tendency to track from childhood into adulthood. The aim of this manuscript is to assess the association between meeting or not meeting the PA and SST recommendations and the consumption of different food groups.

Aim: To assess the relationship between the family meal environment and food and macronutrient consumption in European adolescents.
Article Synopsis
- The goal of the study was to create a new way to measure how health motivation affects food choices and see how it connects to what people eat and their health indicators.
- Researchers used surveys and health tests from 2954 teens across ten cities in Europe to gather information.
- The new measurement tool, called SOFIE, shows that people who score higher are likely to eat healthier foods like cereals, dairy, meats, and fish, and also have better vitamins in their blood, while lower scores are linked to drinking alcohol.
Aim: From a nutrigenetics perspective, we aim to investigate the moderating role of the Mediterranean diet and each of its subgroups in the association between C-reactive protein (CRP) gene polymorphisms and CRP blood concentration in adolescents.
Methods: In 562 adolescents (13-17 y) of the European HELENA study, data was available on circulating CRP levels as inflammatory biomarker, three CRP gene SNPs (rs3093068, rs1204, rs1130864), food intake determined by a self-administered computerized 24 h-dietary recall for 2 days, and body composition. A 9-point Mediterranean diet score and each food subgroup were tested as moderator via SNP*diet interaction.
: The aim of this study was to identify dietary patterns (DPs) in European adolescents and to examine the association between perceptions of healthy eating and the obtained DPs. A multinational cross-sectional study was carried out in adolescents aged 12.5 to 17.

This study aimed to evaluate the association between intake of total polyphenols, polyphenol classes and the 10 most consumed individual polyphenols with MetS risk in European adolescents.
Methods: Of the cross-sectional HELENA study, 657 adolescents (54% girls; 14.
Objectives: To delineate the clustering of energy balance-related behaviors in adolescents and investigate whether these behaviors are associated with the household socioeconomic status and parental education level.
Methods: Two cross-sectional studies assessed information on sedentary behavior, physical activity, sugar-sweetened beverages and fruit and vegetable consumption, and sleep duration by self-reported questionnaires in adolescents (12.5-17.
Background Adolescents having early puberty (EP) are more likely to have obesity and increased cardiometabolic and inflammatory markers and atherosclerosis risk. We aimed to assess the indirect and mediated effects of leptin and adiposity on the relation between EP and cardiometabolic and inflammatory markers in European adolescents. Methods A sample of 511 adolescents with EP (12.
View Article and Find Full Text PDFObjective: To examine the associations between adolescents' diet quality and their perceived relatives' and peers' diet engagement and encouragement.
Design: Cross-sectional study performed in European countries. Diet quality was scored using the Diet Quality Index for Adolescents (DQI-A) based on four components: quality, diversity, balance and meal frequency.
Purpose: Knowledge about polyphenols intakes and their determinants among adolescents might be helpful for planning targeted prevention strategies at an early age.
Methods: In the European multicenter cross-sectional HELENA study of 2006-2007, 2428 subjects (47% boys) had data on dietary intake of polyphenols from 2 non-consecutive 24 h recalls via linking with the Phenol-Explorer database. Differences by sex, age, country, BMI, maternal education, paternal education, family affluence, smoking status, alcohol use, and physical activity were explored by linear regression.
Aim: To assess if a healthy diet might attenuate the positive sedentary-inflammation relation, whereas an unhealthy diet may increase the effect of sedentary behaviors on inflammatory biomarkers.
Methods: In 618 adolescents (13-17 years) of the European HELENA study, data were available on body composition, a set of inflammation markers, and food intake assessed by a self-administered computerized 24 h dietary recall for 2 days. A 9-point Mediterranean diet score and an antioxidant-rich diet z-score were used as dietary indices and tested as moderators.
Aim: Our aim is to demonstrate that a healthy diet might reduce the relation between adiposity and inflammation, whereas an unhealthy diet may increase the effect of adiposity on inflammatory biomarkers.
Methods: In 618 adolescents (13-17 years) of the European HELENA study, data were available on body composition, a set of inflammation markers, and food intake determined by a self-administered computerized 24-h recall. A 9-point Mediterranean diet score and an antioxidant-rich diet score were used as dietary parameters and tested as moderator.
Background: Sedentary behavior is associated with health risks in adults. The potential benefits of reducing sedentary time may be dependent not only on decrease per se, but also on the type of activity it replaces. Few longitudinal studies have investigated the effects on mortality when replacing objectively assessed sedentary time with another physical activity (PA) behavior.

Design: Longitudinal prospective cohort study.
Methods: Data from 851 persons (56% women) ≥35 years at baseline were included.
The aim of this study was to assess physical activity (PA) awareness of adolescents and to identify anthropometric and psychosocial factors that can lead to under or overestimation of PA. This study included 2044 adolescents. Participants wore a uniaxial accelerometer for 7 days to measure PA and completed a self-rated questionnaire about PA.
View Article and Find Full Text PDFObjective: To investigate dietary sources of Ca and vitamin D (VitD) intakes, and the associated sociodemographic and lifestyle factors, among European adolescents.
Design: Linear regression mixed models were used to examine sex-specific associations of Ca and VitD intakes with parental education, family affluence (FAS), physical activity and television (TV) watching while controlling for age, Tanner stage, energy intake and diet quality.
Setting: The Healthy Lifestyle in Europe by Nutrition in Adolescence (HELENA)Cross-Sectional Study.
Aim: To test whether the Mediterranean diet score and each food-subgroup is associated with inflammatory biomarkers in European adolescents.
Methods: In 464 adolescents (13-17 years) of the European HELENA study, data were available on body composition, inflammation markers, and food intake determined by two computerized 24-h recalls. The Mediterranean diet score and its food-subgroups (Vegetables, Fruits and Nuts, Pulses, Cereal and Roots, Monounsaturated/Saturated fat ratio, Dairy, Fish, Meat and Alcohol) were evaluated.
Purpose: Childhood obesity is one of the major concerns in the last years due to the association with future health problems and all-cause mortality. However, there is a subset of adolescents with overweight/obesity who present a metabolic healthy profile. Therefore, the aim of this study was to examine the prevalence of metabolically healthy but overweight/obese adolescents and whether sedentary time, physical activity, and fitness differ between metabolically healthy and nonmetabolically healthy phenotypes.

- - The study aimed to explore the relationship between amino acid (AA) intake and physical fitness in European adolescents, considering whether any associations were affected by carbohydrate intake.
- - Among boys, certain amino acids (tryptophan, histidine, and methionine) showed a positive link to lower limb fitness, but these associations disappeared when controlling for carbohydrates; girls had a weaker association with proline and leucine.
- - Ultimately, after adjusting for multiple tests, no significant connections between amino acid intake and physical fitness were established, suggesting that the initial findings were not robust.
Purpose: To examine the underlying reasons for the positive relation between socio-economic status (SES) and the diet quality of adolescents.
Methods: In 2081 adolescents (12.5-17.
Objectives: To examine the association of health-related physical fitness components and accurate measures of fatness with attention in European adolescents.
