Abstract
BACKGROUND The eating patterns of school-aged children rarely meet recommendations: meal frequency is irregular and the consumption of vegetables is lower and sugar-sweetened products higher than recommended. Although school is an excellent arena for nutrition education to support pupils eating patterns, teachers usually lack efficient tools. The present study aimed to develop a curriculum for nutrition education to be used by teachers and to examine its efficacy in the school environment with respect to the eating patterns of pupils. METHODS The curriculum was developed in collaboration with school teachers using self-determination theory as a theoretical standpoint. The Health at Every Size concept and sensory-based food education were utilised in the curriculum. Self-reported questionnaires were used to assess the feasibility and impact of the curriculum. Fourteen teachers implemented the curriculum during 2012-2013 with 194 pupils aged 10-13 years (fifth and sixth grades). The control schools included 140 pupils of the same age not following the curriculum. RESULTS The teachers reported that the curriculum was easy to integrate in the school environment. The fifth graders improved their breakfast frequency, increased their consumption of vegetables and reduced their consumption of ice cream, sweets and sugar-sweetened drinks. No improvement was found in the fifth graders at the control schools. In the sixth graders, no dietary changes were detected in the intervention or control schools. CONCLUSIONS The pupils in the fifth grade appeared to comprise a responsive target group for nutrition education at schools. The curriculum offers a promising approach for developing healthy eating patterns among fifth graders. Collaboration with teachers in developing the curriculum likely enhanced its feasibility and teacher commitment for implementation.

Abstract
Obesity and its medical complications represent a significant problem throughout the world. In recent decades, mechanisms underlying the progression of obesity have been intensively examined. The involvement of both the behavioral aspects, such as calorie-rich diet, low physical activity and sleep deprivation, and the intrinsic factors, including adipose tissue deregulation, chronic inflammation, oxidative stress, and chronodisruption, has been identified. The circadian disturbances of the adipose tissue endocrine function have been correlated with obesity. Leptin and adiponectin are adipokines strongly associated with glucose and lipid metabolism and with energy balance. Their synthesis and secretion display circadian rhythms that are disturbed in the obese state. Hyperleptinemia resulting in leptin resistance, and hypo-adiponectinemia have been linked to the pathophysiology of the obesity-related disorders. A deficiency of melatonin, one of the consequences of sleep deprivation, has also been demonstrated to correlate with obesity. Melatonin is a pineal secretory product involved in numerous actions, such as regulation of internal biological clocks and energy metabolism, and it functions as an antioxidant and as an anti-inflammatory agent. There exists a substantial amount of evidence supporting the beneficial effects of melatonin supplementation on obesity and its complications. In the current review, the results of studies related to the interactions between melatonin, and both leptin and adiponectin are discussed. Despite the existence of some inconsistencies, melatonin has been found to normalize the expression and secretion patterns of both adipokines. These results support the concept of melatonin as a potential therapeutic agent for obesity and related disorders.

Abstract
The purpose of this article was to review primary prevention interventions targeting childhood obesity implemented in the after school environment from 2006 and 2011. A total of 20 interventions were found from 25 studies. Children in the interventions ranged from kindergarten to middle schoolers, however a majority was in the 4th and 5th grades. Most of the interventions targeted both physical activity and dietary behaviors. Among those that focused on only one dimension, physical activity was targeted more than diet. The duration of the interventions greatly varied, but many were short-term or brief. Many interventions were also based on some behavioral theory, with social cognitive theory as the most widely used. Most of the interventions focused on short-term changes, and rarely did any perform a follow-up evaluation. A major limitation among after school interventions was an inadequate use of process evaluations. Overall, interventions resulted in modest changes in behaviors and behavioral antecedents, and results were mixed and generally unfavorable with regards to indicators of obesity. Recommendations for enhancing the effectiveness of after school based childhood obesity interventions are presented.

Abstract
AbstractObjectiveTo assess the short-term impact of a nutritional intervention aimed at reducing childhood overweight in German pre-school children.DesignUsing a cluster-randomized study design with waiting-list controls, we tested a 6-month intervention administered once weekly by a nutrition expert consisting of joint meal preparation and activities for children and parents such as tasting and preparing nutritious, fresh foods. At baseline, 6 and 12 months, a parent-completed questionnaire assessed fruit and vegetable intakes (primary outcomes) and water and sugared drinks consumption (secondary outcomes). Direct measurement assessed BMI, skinfold thickness and waist-to-height-ratio. An intention-to-treat analysis used random-effects panel regression models to assess the intervention effect, adjusted for each child's age, gender, immigrant background and maternal education.SettingEighteen pre-schools from three south German regions.SubjectsHealthy children aged 3–6 years.ResultsThree hundred and seventy-seven (80 %) eligible pre-school children participated in the study. Of these, 348 provided sufficient data for analysis. The sample mean age was 4·26 (sd 0·78) years; the majority (53·2 %) were boys. Children's fruit and vegetable intakes increased significantly (P < 0·001 and P < 0·05, respectively); no significant changes in the consumption of water, sugared drinks or anthropometric measurements were noted.ConclusionsNutritional interventions in pre-schools have the potential to change eating behaviours in young children, which in the long term might reduce risk for developing overweight.

Abstract
A worldwide increase in the incidence of obesity indicates the unsuccessful battle against this disorder. Obesity and the associated health problems urgently require effective strategies of treatment. The new discovery that a substantial amount of functional brown adipose tissue (BAT) is retained in adult humans provides a potential target for treatment of human obesity. BAT is active metabolically and disposes of extra energy via generation of heat through uncoupling oxidative phosphorylation in mitochondria. The physiology of BAT is readily regulated by melatonin, which not only increases recruitment of brown adipocytes but also elevates their metabolic activity in mammals. It is speculated that the hypertrophic effect and functional activation of BAT induced by melatonin may likely apply to the human. Thus, melatonin, a naturally occurring substance with no reported toxicity, may serve as a novel approach for treatment of obesity. Conversely, because of the availability of artificial light sources, excessive light exposure after darkness onset in modern societies should be considered a potential contributory factor to human obesity as light at night dramatically reduces endogenous melatonin production. In the current article, the potential associations of melatonin, BAT, obesity and the medical implications are discussed.

Abstract
O objetivo da pesquisa foi identificar casos de excesso de peso em adolescentes de escolas particulares de Fortaleza - Brasil. Foram investigados 794 estudantes entre 12 e 17 anos de idade, de 12 escolas privadas, nos meses de março-junho e agosto-setembro de 2007. A prevalência de sobrepeso e obesidade foi, respectivamente, de 20% e 4%. O sobrepeso foi maior, e duplicado os casos de obesidade, naqueles que mantinham o hábito de assistir tevê durante as refeições (p= 0, 000). Cerca de 28% dos jovens ativos apresentavam excesso de peso (p < 0, 001). No combate à adiposidade juvenil, cabe a enfermagem, principalmente, realizar as ações preventivas, pois atenuam diversas repercussões patológicas, relacionados com o acúmulo de peso corporal.

Abstract
Overweight and obesity continue to be health concerns facing today’s adolescent population. Along with metabolic and physical problems associated with obesity, today’s obese adolescents also face many psychological issues such as high rates of depression, anxiety, and social discrimination. Obesity is commonly recognized as having many causes, such as genetic, lifestyle and environmental. There are four major modalities for management of overweight and obesity in adolescents: dietary management, increasing physical activity, pharmacological therapy, and bariatric surgery. The purpose of this study was to conduct a review of novel and emerging approaches for preventing and managing adolescent obesity. It was found that while not always the case, theory driven approaches are being better utilized in newer interventions especially by those directed toward prevention. New theories that are being used are the theories of reasoned action, planned behavior, intervention mapping, and social marketing. Schools are found to be the most common place for such interventions, which is appropriate since virtually all children attend some form of private or public school. Limitations found in many studies include the underuse of process evaluations, the low number of studies attempted, environmental or policy changes, and that not all studies used a similar control group for comparison.

Abstract
Background With rates of childhood obesity increasing, physical activity (PA) promotion especially in young children has assumed greater importance. Given the limited effectiveness of most interventions to date, new approaches are needed. The General Systems theory suggests that involving parents as intervention targets may be effective in fostering healthier life styles in children. We describe the development of a parent-focused participatory intervention and the procedures used to evaluate its effectiveness in increasing daily PA in preschoolers. Methods/Design Thirty-seven South German preschools were identified for this study and agreed to participate. Using a two-armed, controlled cluster-randomized trial design we test a participatory intervention with parents as the primary target group and potential agents of behavioural change. Specifically, the intervention is designed to engage parents in the development, refinement and selection of project ideas to promote PA and in incorporating these ideas into daily routines within the preschool community, consisting of children, teachers and parents. Our study is embedded within an existing state-sponsored programme providing structured gym lessons to preschool children. Thus, child-based PA outcomes from the study arm with the parent-focused intervention and the state-sponsored programme are compared with those from the study arm with the state-sponsored programme alone. The evaluation entails baseline measurements of study outcomes as well as follow-up measurements at 6 and 12 months. Accelerometry measures PA intensity over a period of six days, with the mean over six days used as the primary outcome measure. Secondary outcomes include childrens' BMI, a sum of averaged skin fold thickness measurements across multiple sites, and PA behaviour. Longitudinal multilevel models are used to assess within-subject change and between-group differences in study outcomes, adjusted for covariates at the preschool and individual levels. Teacher qualitative interviews monitor the intervention implementation process. Discussion Participatory approaches that actively involve parents have the potential to promote PA in ways that might be better tailored to local needs and more sustainable. Our mixed methods approach to assess the intervention efficacy and implementation employing both quantitative and qualitative measures within a cluster-randomized controlled trial may serve as a framework for evaluating public health interventions in preschool settings.
