Show Abstract
Hide Abstract
High levels of sedentary behavior are often measured in preschoolers, but only a few interventions have been developed to counteract this. Furthermore, detailed descriptions of interventions in preschoolers targeting different forms of sedentary behavior could not be located in the literature. The aim of the present paper was to describe the different steps of the Intervention Mapping Protocol used towards the development of an intervention component of the ToyBox-study focusing on decreasing preschoolers' sedentary behavior. The ToyBox-study focuses on the prevention of overweight in 4- to 6-year-old children by implementing a multi-component kindergarten-based intervention with family involvement in six different European countries.

EURRECA-Evidence-based methodology for deriving micronutrient recommendations.
Crit Rev Food Sci Nutr
PUBLISHED: 08-20-2013
Show Abstract
Hide Abstract
The EURopean micronutrient RECommendations Aligned (EURRECA) Network of Excellence explored the process of setting micronutrient recommendations to address the variance in recommendations across Europe. Work centered upon the transparent assessment of nutritional requirements via a series of systematic literature reviews and meta-analyses. In addition, the necessity of assessing nutritional requirements and the policy context of setting micronutrient recommendations was investigated. Findings have been presented in a framework that covers nine activities clustered into four stages: stage one "Defining the problem" describes Activities 1 and 2: "Identifying the nutrition-related health problem" and "Defining the process"; stage two "Monitoring and evaluating" describes Activities 3 and 7: "Establishing appropriate methods," and "Nutrient intake and status of population groups"; stage three "Deriving dietary reference values" describes Activities 4, 5, and 6: "Collating sources of evidence," "Appraisal of the evidence," and "Integrating the evidence"; stage four "Using dietary reference values in policy making" describes Activities 8 and 9: "Identifying policy options," and "Evaluating policy implementation." These activities provide guidance on how to resolve various issues when deriving micronutrient requirements and address the methodological and policy decisions, which may explain the current variation in recommendations across Europe.

EURRECA-Framework for Aligning Micronutrient Recommendations.
Crit Rev Food Sci Nutr
PUBLISHED: 08-20-2013
Show Abstract
Hide Abstract
There is currently no standard approach for deriving micronutrient recommendations, and large variations exist across Europe, causing confusion among consumers, food producers, and policy makers. More aligned information could influence dietary behaviors and potentially lead to a healthier population. Funded by the European Commission, EURRECA (EURopean micronutrient RECommendations Aligned) has developed methods and applications to guide Nutrient Recommendation Setting Bodies through the process of setting micronutrient reference values. The EURRECA approach is crystallized into its framework that outlines a standard process for deriving and using dietary reference values for micronutrients in a transparent, systematic, and scientific way. The 9 activities of the framework can be clustered into four stages (i) defining the problem, (ii) monitoring and evaluating, (iii) deriving dietary reference values, and (iv) using dietary reference values in policy making. The EURRECA framework should not be interpreted as a prescriptive description of a linear process, but as a structured guide for checking that all issues essential for deriving requirements have at least been considered.

Psychosocial Determinants and Perceived Environmental Barriers as Mediators of the Effectiveness of a Web-Based Tailored Intervention Promoting Physical Activity in Adolescents: the HELENA Activ-O-Meter.
J Phys Act Health
PUBLISHED: 05-10-2013
Show Abstract
Hide Abstract
BACKGROUND: The aim was to examine if psychosocial determinants (attitudes, self-efficacy, social support from a sports partner) and perceived environmental barriers (PEB) of physical activity (PA) mediated the effect of a 3-month internet-based intervention on PA in European adolescents. METHODS: A random sample of 536 adolescents (51% boys) aged 12-17 years were randomly assigned to intervention or control condition. Questionnaires were used to assess different PA behaviours, psychosocial determinants and PEB at baseline and at 3-months follow-up. Mediating effects were assessed with the bootstrapping method. RESULTS: PEB regarding neighbourhood safety mediated the effect of the intervention on all PA indices. PEB regarding sports facilities availability at neighbourhood and PEB regarding sport-related facilities availability at school mediated the effect of the intervention on moderate to vigorous PA (MVPA) and moderate PA (in leisure time and at school, respectively). Social support from a sports partner suppressed the effect of the intervention on vigorous PA and MVPA. No other factor had a mediation effect. CONCLUSIONS: All PEB measures appear to mediate PA behaviours of different intensities and in different contexts. Interventions promoting PA in adolescents should also focus on improving the targeted PEB as mediators of engagement in PA to bring the desired effects in actual behaviours.

Hide Abstract
Evidence has grown supporting the role for short sleep duration as an independent risk factor for weight gain and obesity. The purpose of the present study was to examine the relationship between sleep duration and dietary quality in European adolescents. The sample consisted of 1522 adolescents (aged 12.5-17.5 years) participating in the European multi-centre cross-sectional ‘Healthy Lifestyle in Europe by Nutrition in Adolescence’ study. Sleep duration was estimated by a self-reported questionnaire. Dietary intake was assessed by two 24 h recalls. The Diet Quality Index for Adolescents with Meal index (DQI-AM) was used to calculate overall dietary quality, considering the components dietary equilibrium, dietary diversity, dietary quality and a meal index. An average sleep duration of ? 9 h was classified as optimal, between 8 and 9 h as borderline insufficient and < 8 h as insufficient. Sleep duration and the DQI-AM score were positively associated (? = 0.027, r 0.130, P< 0.001). Adolescents with insufficient (62.05 (sd 14.18)) and borderline insufficient sleep (64.25 (sd 12.87)) scored lower on the DQI-AM than adolescents with an optimal sleep duration (64.57 (sd 12.39)) (P< 0.001; P= 0.018). The present study demonstrated in European adolescents that short sleep duration was associated with a lower dietary quality. This supports the hypothesis that the health consequences of insufficient sleep may be mediated by the relationship of insufficient sleep to poor dietary quality.

FADS1 genetic variability interacts with dietary ?-linolenic acid intake to affect serum non-HDL-cholesterol concentrations in European adolescents.
J. Nutr.
PUBLISHED: 05-18-2011
Show Abstract
Hide Abstract
Two rate-limiting enzymes in PUFA biosynthesis, ?5- and ?6-desaturases, are encoded by the FADS1 and FADS2 genes, respectively. Genetic variants in the FADS1-FADS2 gene cluster are associated with changes in plasma concentrations of PUFA, HDL- and LDL-cholesterol, and TG. However, little is known about whether dietary PUFA intake modulates these associations, especially in adolescents. We assessed whether dietary linoleic acid (LA) or ?-linolenic acid (ALA) modulate the association between the FADS1 rs174546 polymorphism and concentrations of PUFA, other lipids, and lipoproteins in adolescents. Dietary intakes of LA and ALA, FADS1 rs174546 genotypes, PUFA levels in serum phospholipids, and serum concentrations of TG, cholesterol, and lipoproteins were determined in 573 European adolescents from the HELENA study. The sample was stratified according to the median dietary LA (?9.4 and >9.4 g/d) and ALA (?1.4 and >1.4 g/d) intakes. The associations between FADS1 rs174546 and concentrations of PUFA, TG, cholesterol, and lipoproteins were not affected by dietary LA intake (all P-interaction > 0.05). Similarly, the association between the FADS1 rs174546 polymorphism and serum phospholipid concentrations of ALA or EPA was not modified by dietary ALA intake (all P-interaction > 0.05). In contrast, the rs174546 minor allele was associated with lower total cholesterol concentrations (P = 0.01 under the dominant model) and non-HDL-cholesterol concentrations (P = 0.02 under the dominant model) in the high-ALA-intake group but not in the low-ALA-intake group (P-interaction = 0.01). These results suggest that dietary ALA intake modulates the association between FADS1 rs174546 and serum total and non-HDL-cholesterol concentrations at a young age.

Show Abstract
Hide Abstract
Obesity treatment is by large ineffective long term, and more emphasis on the prevention of excessive weight gain in childhood and adolescence is warranted. To inform energy balance related behaviour (EBRB) change interventions, insight in the potential personal, family and school environmental correlates of these behaviours is needed. Studies on such multilevel correlates of EBRB among schoolchildren in Europe are lacking. The ENERGY survey aims to (1) provide up-to-date prevalence rates of measured overweight, obesity, self-reported engagement in EBRBs, and objective accelerometer-based assessment of physical activity and sedentary behaviour and blood-sample biomarkers of metabolic function in countries in different regions of Europe, (2) to identify personal, family and school environmental correlates of these EBRBs. This paper describes the design, methodology and protocol of the survey.

FTO genotype and adiposity in children: physical activity levels influence the effect of the risk genotype in adolescent males.
Eur. J. Hum. Genet.

Show Abstract
Hide Abstract
Studies of the fat mass and obesity-associated (FTO) gene provide compelling evidence of genetic variation in the general population that influences fat levels and obesity risk. Studies of the interaction between genetic and environmental factors such as physical activity (PA) will promote the understanding of how lifestyle can modulate genetic contributions to obesity. In this study, we investigated the effect of FTO genotype, and interactions with PA or energy intake, in young children and adolescents. In all, 1-5-year-old children from the Growth, Exercise and Nutrition Epidemiological Study in preSchoolers (GENESIS) study (N=1980) and 11-18-year-old Greek adolescents (N=949) were measured for adiposity-related phenotypes and genotyped at the FTO single-nucleotide polymorphism (SNP) marker, rs17817449. Adolescents were classified as physically active or inactive based on self-reported levels of PA. In adolescents, FTO genotype influenced weight (P=0.001) and BMI (P=0.007). There was also a significant SNP(*)PA(*)gender interaction (P=0.028) on BMI, which reflected the association between FTO genotype and BMI in males (P=0.016), but not females (P=0.15), and significant SNP(*)PA interaction in males (P=0.007), but not females (P=0.74). The FTO genotype effect was more pronounced in inactive than active males. Inactive males homozygous for the G allele had a mean BMI 3?kg/m(2) higher than T carriers (P=0.008). In the GENESIS study, no significant association between FTO genotype and adiposity was found. The present findings highlight PA as an important factor modifying the effect of FTO genotype.

Hide Abstract
The aim of the current study was to compare the association of several anthropometric indices, with insulin resistance (IR) proxy measures in European adolescents. The present study comprises 1,097 adolescents aged 12.5-17.5 from ten European cities participating in the HELENA study. Weight, height, waist circumference (WC) and hip circumference, skinfolds thickness, fat mass (FM), fasting plasma glucose (G(F)) and serum insulin (I(F)) levels were measured. HOMA (as indicator of IR body mass index (BMI), waist to hip ratio (WHR) and waist to height ratio (WHtR) were calculated. I(F) and HOMA were statistically significantly related to BMI, WC, skinfold sum, WHtR, WHR and FM. BMI, WC, WHtR, skinfold sum and FM displayed similar correlation with I(F) and HOMA as opposed to WHR where lower correlation with IR indices was detected in the overall sample. Similar results were found for boys, girls and underweight/normal weight adolescents. On the other hand, WC and WHtR were found to be more strongly associated with IR proxy measures compared to the rest of anthropometric indices among overweight/obese subjects. Based on the current findings, WC and WHtR could be used, alternatively, to identify the overweight/obese adolescent at risk for developing IR. In addition, all aforementioned anthropometric indices, except WHR, could be used among the underweight/normal weight adolescents.

Hide Abstract
Prevention of early childhood obesity requires a clear understanding of its determinants. This study examined perinatal, parental, and lifestyle determinants of childhood obesity and how these factors are associated with maternal misperceptions of their childrens weight status. The current work presents a cross-sectional analysis of 2,374 children, age 1 to 5 years, living in Greece (April 2003 to July 2004). The 2000 Centers for Disease Control and Prevention growth charts were used to classify children as overweight (?85th and <95th body mass index [BMI]-for-age percentile for children older than 24 months) and obese (?95th weight-for-length percentile for children younger than 24 months and ?95th BMI-for-age percentile for children older than 24 months). Maternal perceptions about their childrens weight status were assessed via interviews with the mothers. Early infancy growth data were obtained from pediatric medical records. The present study showed that the prevalence of overweight and obesity was 16.2% and 17.5%, respectively. Each unit increase of maternal and paternal BMI significantly increased the likelihood of childhood obesity by a factor of 1.03 (95% confidence interval [CI]: 1.01 to 1.07) and 1.15 (95% CI: 1.10 to 1.20), respectively. Furthermore, children with a rapid weight gain in infancy were 1.9 (95% CI: 1.3 to 2.7) times more likely to be overweight and 1.5 (95% CI: 1.2 to 1.9) times more likely to have their weight status underestimated by their mother. In conclusion, rapid infancy weight gain and higher parental BMI were the main determinants of obesity in preschool years. Maternal underestimation of childrens weight status was more likely for children with rapid weight gain in infancy.

Hide Abstract
The rise of asthma prevalence in children observed the last years might be related to several dietary factors/components as suggested by several researchers. We aimed to evaluate the potential relationship between certain nutrients intake and asthma occurrence in a population of pre-school children. In the framework of the cross-sectional study Growth, Exercise and Nutrition Epidemiological Study In pre-schoolers, data were collected from 1964 children, aged 24-72 months, living in five different counties in Greece. The International Study of Asthma and Allergies in Childhood questionnaire was used to assess asthma related outcomes. Dietary intake was assessed with 3 days diet records. The prevalence of ever wheeze, current wheeze and diagnosed asthma was 37.7%, 27.5% and 10.5% respectively. Dietary intake of magnesium had a 0.5% and 0.6% increase in the reported risk of current wheeze and diagnosed asthma respectively. On the contrary a decrease in the prevalence of ever (OR: 0.997, 95% CI: 0.995-1.000) and current wheeze (OR: 0.996, 95% CI: 0.993-0.999) was associated with vitamin C intake. Calcium intake slightly decreased the risk of current wheeze (OR: 0.999, 95% CI: 0.998-0.999). An increase of 2% of the risk of reporting ever or current wheeze was associated with mono-unsaturated fatty acid intake. Magnesium intake was the only independent predictor for doctors diagnosed asthma. We conclude that dietary intake of vitamin C and calcium seem to have a protective effect on the incidence of wheeze in pre-school children, whereas magnesium and mono-unsaturated fatty acid may have a harmful role.

The aim of the current study was to evaluate the association between television (TV) viewing time and dietary habits of preschoolers. A representative sample of 2,374 Greek children aged 1-5 years was examined (GENESIS study). The majority of participants (74.0%) spent less than 2 h/day watching TV. Children spending > or =2 h/day watching TV seem to have higher energy intake compared to children watching TV less than 2 h/day, even after adjustment for potential confounders (p < 0.001). Furthermore, it was detected that the former were more likely to consume more than 5, 2, and 1.5 exchanges of fat, meat, and other carbohydrates per day, respectively, compared to the latter. In conclusion, the current findings indicate that prolonged TV viewing time may be associated with increased consumption of high-fat and high-sugar foods resulting in increased daily energy intake. Therefore, interventions aiming to modify childrens TV viewing behaviour might need to be implemented.

Hide Abstract
Environmental tobacco smoke (ETS) is a significant risk factor for the presence and increased severity of asthma- and allergy-related symptoms in children. Smoking during pregnancy has detrimental effects on asthma-associated outcomes in childhood. Whether passive exposure of pregnant women to ETS may also lead to asthma in their offspring, is not known. The aim of this study was to investigate the association of passive exposure of pregnant women to ETS and asthma- and/or allergy-related symptoms in Preschool children. Cross-sectional data were collected with questionnaires from 2374 Preschool children, recruited from public and private nurseries and day-care centers. Parental smoking was significantly associated with wheezing symptoms in their children. Mothers active smoking during pregnancy significantly increased the risk for occurrence of asthma symptoms and/or medically diagnosed asthma in Preschool children in a dose-dependent manner. Passive exposure to ETS, mainly during the third trimester of pregnancy, was significantly associated with asthma- and allergy-related symptoms after adjusting for several confounders in a multivariate analysis (current wheeze: OR = 1.42, 95% CI = 1.06-1.91, pruritic rash ever: OR= 1.45, 95% CI = 1.01-2.08). Passive exposure of pregnant women to ETS during the third trimester is positively associated with asthma- and allergy-related symptoms in their Preschool age children. Public health policies should be oriented not only towards smoking cessation, but also reinforce elimination of ETS exposure of pregnant women.

Hide Abstract
The aim of the current work was to evaluate the effect of preschoolers television (TV) watching time on the prevalence of obesity even after controlling for their total energy intake and their physical activity status. A representative sample of 2,374 Greek children aged 1-5 years was examined ("Growth, Exercise and Nutrition Epidemiological Study in preSchoolers", GENESIS study). Childrens TV watching time on a usual weekday and at a usual weekend was recorded. The overall mean of childrens TV viewing time was 1.32 h/day. The majority of participants (74.0%) spent <2 h/day watching TV whereas only 3.1% spent >4 h/day in front of a TV set. Overall, 65.2% of participants were normal weight, 17.2% were overweight, and the rest 17.6% were obese. The prevalence of obesity was significantly higher among those with TV viewing time >or=2 h/day (21.7%) compared to those watching TV <2 h/day (16.1%, P = 0.003). TV viewing time remained significantly associated with the likelihood of being obese even after controlling for potential confounders (i.e., socio demographic and other characteristics and physical activity status) only among children aged 3-5 years. However, further adjusting for childrens total energy intake revealed that the association between the TV viewing time and the probability of being obese was no longer statistically significant. On the other hand, physical activity status continued to be an independent factor of being obese. The current findings support the hypothesis that the effect of TV viewing time on childhood obesity is independent of physical activity status and may be attributed to the increased total energy intake during TV watching.

Show Abstract
Hide Abstract
OBJECTIVE: The current study aimed to evaluate the effect of fortified milk combined with a lifestyle and counselling programme on several CVD risk factors after a 3-month dietary intervention. DESIGN: Hypercholesterolaemic adults were randomized to a group supplemented with low-fat milk that was enriched with phytosterols, ?-linolenic and linoleic fatty acids, vitamins and antioxidants (enriched milk group, EMG: n 40), a placebo milk group (PMG: n 36) or a control group (CG: n 25). The EMG and PMG consumed respectively 500 ml of enriched milk or placebo milk daily and attended biweekly counselling sessions over a 3-month period. SETTING: Harokopio University, Athens, Greece. SUBJECTS: A sample of 101 hypercholesterolemic adults aged 40-60 years. RESULTS: Regarding lifestyle changes, total and saturated fat intakes decreased significantly in both intervention groups compared with the CG (P < 0·005). Furthermore, total steps were increased (P = 0·029) and BMI was decreased (P = 0·017) significantly in both intervention groups compared with the CG. Regarding biochemical indices, EPA content in erythrocyte membranes increased (P < 0·001) while serum C-reactive protein decreased (P = 0·003) significantly in both intervention groups compared with the CG. Finally, significant increases in plasma folic acid and vitamin B12 levels and a significant decrease in homocysteine levels were observed in the EMG compared with the PMG and CG (all P < 0·001). A favourable change in LDL cholesterol:HDL cholesterol was also observed in the EMG and tended to be significant compared with the PMG and CG (P = 0·066). CONCLUSIONS: The present study showed that consumption of fortified milk accompanied with lifestyle counselling induces extra benefits in terms of LDL cholesterol:HDL cholesterol and serum homocysteine levels.

Validation of the Diet Quality Index for Adolescents by comparison with biomarkers, nutrient and food intakes: the HELENA study.
Br. J. Nutr.
Show Abstract
Hide Abstract
Food-based dietary guidelines (FBDG) aim to address the nutritional requirements at population level in order to prevent diseases and promote a healthy lifestyle. Diet quality indices can be used to assess the compliance with these FBDG. The present study aimed to investigate whether the newly developed Diet Quality Index for Adolescents (DQI-A) is a good surrogate measure for adherence to FBDG, and whether adherence to these FBDG effectively leads to better nutrient intakes and nutritional biomarkers in adolescents. Participants included 1804 European adolescents who were recruited in the Healthy Lifestyle in Europe by Nutrition in Adolescence (HELENA) Study. Dietary intake was assessed by two, non-consecutive 24 h recalls. A DQI-A score, considering the components dietary quality, diversity and equilibrium, was calculated. Associations between the DQI-A and food and nutrient intakes and blood concentration biomarkers were investigated using multilevel regression analysis corrected for centre, age and sex. DQI-A scores were associated with food intake in the expected direction: positive associations with nutrient-dense food items, such as fruits and vegetables, and inverse associations with energy-dense and low-nutritious foods. On the nutrient level, the DQI-A was positively related to the intake of water, fibre and most minerals and vitamins. No association was found between the DQI-A and total fat intake. Furthermore, a positive association was observed with 25-hydroxyvitamin D, holo-transcobalamin and n-3 fatty acid serum levels. The present study has shown good validity of the DQI-A by confirming the expected associations with food and nutrient intakes and some biomarkers in blood.

A review of methods to assess parental feeding practices and preschool childrens eating behavior: the need for further development of tools.
J Acad Nutr Diet
Show Abstract
Hide Abstract
We reviewed tools developed to measure parental feeding practices and eating behavior and food intake or preferences of children aged 0 to 5 years. Two electronic literature databases (Medline and Psycinfo) were used to search for both observational and experimental studies in human beings. The articles selected for review were those presenting tools with data on internal consistency and/or test-retest reliability and/or construct validity. A total of 3,445 articles were retrieved, and further searching of reference lists and contact with experts produced an additional 18 articles. We identified three tools on the qualitative dimension of childrens eating behavior, two tools on food intake or preferences, and one tool on parental feeding practices with rigorous testing of internal consistency, construct validity, and test-retest reliability. All other tools presented in this review need further evaluation of their validity or reliability. Because major gaps exist, we highlight the need for more tools on parental attention to childrens hunger and satiety cues, and the need to evaluate the degree of control allowed to children younger than age 2 years in feeding events. Food avoidance (ie, behaviors or strategies to take away and to reject food) and food approach (ie, attractiveness for food stimuli) have not been assessed in children aged 12 to 24 months. Food preference tests based on sensory aspects rather than nutritional quality may be worth investigating. We identified a need for further evaluation of quality, especially test-retest reliability and construct validity, for most tools developed for use in studying children aged 0 to 5 years.

What is Visualize?

JoVE Visualize is a tool created to match the last 5 years of PubMed publications to methods in JoVE's video library.

How does it work?

We use abstracts found on PubMed and match them to JoVE videos to create a list of 10 to 30 related methods videos.

Video X seems to be unrelated to Abstract Y...

In developing our video relationships, we compare around 5 million PubMed articles to our library of over 4,500 methods videos. In some cases the language used in the PubMed abstracts makes matching that content to a JoVE video difficult. In other cases, there happens not to be any content in our video library that is relevant to the topic of a given abstract. In these cases, our algorithms are trying their best to display videos with relevant content, which can sometimes result in matched videos with only a slight relation.
