Clustering of energy balance-related behaviors and parental education in European children : the ENERGY-project

Background:Recent research and literature reviews show that, among schoolchildren, some specific energy balance-related behaviors (EBRBs) are relevant for overweight and obesity prevention. It is also well known that the prevalence of overweight and obesity is considerably higher among schoolchildren from lower socio-economic backgrounds. This study examines whether sugared drinks intake, physical activity, screen time and usual sleep duration cluster in reliable and meaningful ways among European children, and whether the identified clusters could be characterized by parental education. Methods: The cross-sectional study comprised a total of 5284 children (46% male), from seven European countries participating in the ENERGY-project ("EuropeaN Energy balance Research to prevent excessive weight Gain among Youth"). Information on sugared drinks intake, physical activity, screen time and usual sleep duration was obtained using validated self-report questionnaires. Based on these behaviors, gender-specific cluster analysis was performed. Associations with parental education were identified using chi-square tests and odds ratios. Results: Five meaningful and stable clusters were found for both genders. The cluster with high physical activity level showed the highest proportion of participants with highly educated parents, while clusters with high sugared drinks consumption, high screen time and low sleep duration were more prevalent in the group with lower educated parents. Odds ratio showed that children with lower educated parents were less likely to be allocated in the active cluster and more likely to be allocated in the low activity/sedentary pattern cluster. Conclusions: Children with lower educated parents seemed to be more likely to present unhealthier EBRBs clustering, mainly characterized by their self-reported time spent on physical activity and screen viewing. Therefore, special focus should be given to lower educated parents and their children in order to develop effective primary prevention strategies

Fluid intake habits of spanish children and adolescents: an update of the Liq.In7 survey

Insufficient and unhealthy total fluid intake (TFI), especially in early stages of life, may have negative health impact [1]. Understanding how fluid consumption may differ throughout the day or as a function of location could help drive policy initiatives to encourage healthier drinking habits, especially in young population groups, so this study assesses current patterns of fluid consumption in children and adolescents in Spain, including drinking occasions and locations and to compare TFI with the adequate intake of water from fluids recommended by the European Food Safety Authority (EFSA)..

Blood cells as a source of transcriptional biomarkers of childhood obesity and its related metabolic alterations: results of the IDEFICS Study

Background: IDEFICS (Identification and Prevention of Dietary-and Lifestyle-Induced Health Effects in Children and Infants Project) is a European multicenter study on childhood obesity. One of its goals is to define early biomarkers of risk associated with obesity and its comorbid conditions. Objective: We considered blood cells as a new potential source of transcriptional biomarkers for these metabolic disorders and examined whether blood cell mRNA levels of some selected genes (LEPR, INSR, CPT1A, SLC27A2, UCP2, FASN, and PPAR alpha) were altered in overweight children and whether their expression levels could be defined as markers of the insulin-resistant or dyslipidemic state associated with overweight. Design: Blood samples were obtained from 306 normal-weight and overweight children, aged 2-9 yr, from eight different European countries. Whole-blood mRNA levels were assessed by quantitative RT-PCR. Results: LEPR, INSR, and CPT1A mRNA levels were higher in overweight compared with normal-weight children (the two latter only in males), whereas SLC27A2 mRNA levels were lower in overweight children. Significant associations were also found between expression levels of LEPR, INSR, CPT1A, SLC27A2, FASN, PPAR alpha, and different parameters, including body mass index, homeostasis model assessment index, and plasma triglycerides and cholesterol levels. These associations showed that high expression levels of CPT1A, SLC27A2, INSR, FASN, or PPAR alpha may be indicative of a lower risk for the insulin-resistant or dyslipidemic state associated with obesity, whereas low LEPR mRNA levels appear as a marker of high low-density lipoprotein cholesterol, independently of body mass index. Conclusions: These findings point toward the possibility of using the expression levels of these genes in blood cells as markers of metabolic status and can potentially provide an early warning of a future disorder

Breakfast characteristics and their association with energy, macronutrients, and food intake in children and adolescents: A systematic review and meta-analysis

Breakfast plays an important role in health because it has been associated with overall health, which includes a high daily nutrient intake and a low risk of chronic diseases. For this reason, we investigated the associations between breakfast consumption and daily energy, macronutrients, and food and beverage consumption. We systematically searched peer-reviewed articles in three datasets (Pubmed, Scopus, and Cochrane). Two independent reviewers evaluated 3188 studies against the inclusion criteria using the Appraisal tool for Cross-Sectional Studies (AXIS) critical appraisal and Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) methodologies. The meta-analysis was performed by comparing results based on type of breakfast consumed (ready to eat cereal breakfasts or other types of breakfasts). Ultimately, 38 studies were included in the review and 7 of them in the energy and macronutrients intake meta-analysis. In the Systematic Review, breakfast consumers had higher energy intake (EI), fibre intake, and higher consumption of fruits and vegetables and lower consumption of soft drinks than breakfast skippers. In the Meta-Analysis, breakfast consumers had a higher carbohydrates intake (MD, -8.21; 95%CI: -11.37, -5.05) and fibre intake (MD, -8.43; 95%CI: -12.63, -4.23) than breakfast skippers. However, breakfast consumers had a lower fat intake (MD, 4.59; 95%CI: 2.04, 7.15). Our review suggests that breakfast consumption is associated with better macronutrient intake and healthier food and beverage consumption

Solvent-Driven Supramolecular Wrapping of Self-Assembled Structures

Self‐assembly relies on the ability of smaller and discrete entities to spontaneously arrange into more organized systems by means of the structure‐encoded information. Herein, we show that the design of the media can play a role even more important than the chemical design. The media not only determines the self‐assembly pathway at a single‐component level, but in a very narrow solvent composition, a supramolecular homo‐aggregate can be non‐covalently wrapped by a second component that possesses a different crystal lattice. Such a process has been followed in real time by confocal microscopy thanks to the different emission colors of the aggregates formed by two isolated PtII complexes. This coating is reversible and controlled by the media composition. Single‐crystal X‐ray diffraction and molecular simulations based on coarse‐grained (CG) models allowed the understanding of the properties displayed by the different aggregates. Such findings could result in a new method to construct hierarchical supramolecular structures

Persistence, clearance and reinfection regarding six high risk human papillomavirus types in Colombian women : A follow-up study

Background: The design of new healthcare schemes which involve using molecular HPV screening means that both persistence and clearance data regarding the most prevalent types of HR-HPV occurring in cities in Colombia must be ascertained.Methods: This study involved 219 HPV positive women in all of whom 6 types of HR-HPV had been molecularly identified and quantified; they were followed-up for 2 years. The Kaplan-Meier survival function was used for calculating the time taken for the clearance of each type of HPV. The role of a group of independent variables concerning the time taken until clearance was evaluated using a Cox proportional-hazards regression model or parametric (log-logistic) methods when necessary. Regarding viral load, the Wilcoxon rank-sum test was used for measuring the difference of medians for viral load for each type, according to the state of infection (cleared or persistent). The Kruskal-Wallis test was used for evaluating the change in the women's colposcopy findings at the start of follow-up and at the end of it (whether due to clearance or the end of the follow-up period).Results: It was found that HPV-18 and HPV-31 types had the lowest probability of becoming cleared (1.76 and 2.75 per 100 patients/month rate, respectively). Women from Colombian cities other than Bogotá had a greater probability of being cleared if they had HPV-16 (HR 2.58: 1.51-4.4 95% CI) or HPV-58 (1.79 time ratio: 1.33-2.39 95% CI) infection. Regarding viral load, HPV-45-infected women having 1 × 106 to 9.99 × 109 viral copies had better clearance compared to those having greater viral loads (1.61 time ratio: 1.01-2.57 95% CI). Lower HPV-31 viral load values were associated with this type's persistence and changes in colposcopy findings for HPV-16 gave the worst prognosis in women having low absolute load values.Conclusions: HPV infection clearance in this study was related to factors such as infection type, viral load and the characteristics of the cities from which the women came. Low viral load values would indicate viral persistence and a worse prognosis regarding a change in colposcopy findings. © 2014 Soto-De León et al.; licensee BioMed Central Ltd

Evaluación de acolchados para el control de la flora arvense en un cultivo de tomate: dos años de resultados

En el presente proyecto se estudian alternativas al uso de acolchado plástico con polietileno, el cual es un residuo de difícil gestión tanto en producción hortícola ecológica como en convencional. Durante los años 2006 y 2007 se han llevado a cabo diez ensayos de campo en tomate de industria regado por goteo en cinco distintos lugares de España. Se han ensayado diferentes materiales biodegradables: dos plásticos biodegradables (Mater-Bi y Biofilm), un plástico oxobiodegradable (Enviroplast), dos papeles (papel negro Mimcord y marrón Saikraft), un acolchado de paja de cebada y dos testigos (sin desherbar y con control manual de las malas hierbas). Todas las películas fueron colocadas con máquina acolchadora, y los papeles requirieron un ajuste especial para evitar roturas. En todas las localidades y en ambos años el control de la flora arvense fue bueno o muy bueno para todos los acolchados, menos para la paja. Respecto al rendimiento de tomate, éste fue muy similar para todos los acolchados en ambos años, aunque ligeramente inferior que para el polietileno. En algunas localidades fue difícil mantener la paja en el suelo debido a su dispersión con el viento, mientras que en otras se mantuvo durante todo el ciclo. A pesar del peor control de la flora arvense, la paja dio buenos rendimientos en algunas localidades. El plástico oxobiodegradable mostró un comportamiento muy irregular entre localidades en cuanto a su degradación y cabe destacar la ausencia de degradación de la parte enterrada en todos los casos. Los plásticos biodegradables se degradaron de forma correcta cuando el cultivo ya cubría parte del suelo. El papel Mimcord fue más elástico permitiendo una más fácil colocación en el suelo pero es sensiblemente más caro que el marrón. En 2007 el rendimiento fue ligeramente menor para el papel marrón en 2007, posiblemente debido a que se trató de un año más frío. Los diferentes materiales biodegradables y el papel negro han sido los tratamientos más productivos y que mejor han controlado la flora arvense. Se concluye que existen alternativas técnicamente viables para sustituir el acolchado con polietileno en el cultivo de tomate de industria. No obstante, el elevado coste de la mayoría de estos materiales es el principal factor limitante para su adopción.Publishe
