Filter by:This research focuses on overweight, sedentary children whose health, cognition, and academic performance are therefore at risk, and who may be particularly responsive to exercise interventions. This study will determine whether regular exercise per se (i.e. compared to attention control, or placebo, condition) benefits children's cognition and achievement, and will provide insight into neural mechanisms. A substudy will examine exercise-induced changes in brain structure. Provision of comprehensive evidence for the benefits of exercise on children's health may reduce barriers to vigorous physical activity programs during a childhood obesity epidemic by persuading policymakers, schools and communities that time spent in physical activity enhances, rather than detracts from, learning.
This study aims to make a proper scientific assessment on the dietary intake and physical activity levels of a representative sample of the urban population of 8 Latin American countries (Argentina, Brazil, Chile, Colombia, Costa Rica, Ecuador, Perú and Venezuela). The study was based on complex, multistage sample design, stratified by conglomerates, being all regions of each country represented, and random selection of main cities within each region according to probability proportional to size method. Sample will be stratified by gender, age (15 to 65 years old), and socioeconomic level. Socioeconomic levels will be balanced and divided in three strata (high, medium and low) based on national indexes used in each country. All the study sites are university-based and will adhere to a common study protocol for training, implementation of fieldwork, data collection and management, and quality control procedures to be performed simultaneously. All participants will be required to provide a written informed consent. A pilot study at small scale will be performed in each country in order to test procedures and tools involved in ELANS. Anthropometric variables, including body weight, height, waist, hip and neck circumferences will be measured according to a standardized protocol. Nutritional intake evaluation will be performed using two 24-hour dietary recalls, with 'multiple pass' procedure and a food frequency questionnaire. Nutritional data will be entered in Nutrition Data System for Research (NDS-R, Minnesota University) after a harmonization process between local foods and NDSR database. Physical activity and energy expenditure will be assessed by IPAQ-long version questionnaire and 7-day accelerometry.
Primary objective is to determine absorption profile of a sugar-based beverage on inflammatory mechanism by timing of beverage consumption relative to meal intake. Secondary objective is to determine absorption profile of a sugar-based beverage on oxidative and metabolic mechanism by timing of beverage consumption relative to meal intake. The results will be served as an internal reference or negative control group to compare with polyphenol containing studies from other studies. Each subject will receive 3 identical placebo drinks at each time points: fasting (0h), with standardized breakfast meal (2h), and 2 hours after the breakfast meal (4h). A planned size of 12 will be recruited into this part of the study. This study is a single-arm design utilizing a multiple sampling, and repeated measures paradigm to evaluate timing influence of consumption of sugar-based beverage associated acute effect on inflammatory markers.
Evaluate the impact of a 12-week behavioral weight management program on body weight and quality of life. We hypothesize that participants will lose body weight and see improved quality of life after program completion.
The metabolic syndrome is rising worldwide as a consequence of the continued obesity epidemic. The current obesogenic environment makes the regulation of energy intake difficult and impedes the maintenance of weight loss. Dietary patterns and/or ingredients that curb hunger and reduce energy intake are critically needed. We hypothesize that inclusion of protein and prebiotic fiber in the diet will reduce adiposity in overweight and obesity adults.
The current project is designed as a 30-day pilot trial to demonstrate the safety and tolerability of resveratrol therapy in overweight adolescents to decrease liver fat, and improve insulin sensitivity to prevent type 2 diabetes.
The main objective of this study is to investigate in detail how a high-(prebiotic)fibre diet and a high-PUFA diet affect the gut microbiota composition in a metabolic challenged population, and if the diet-induced modulation of the gut microbiota mediates changes in metabolic risk markers. Intake of both experimental diets over 4 weeks are expected to induce beneficial changes in the gut microbiota composition and to affect markers for insulin sensitivity, lipid metabolism and inflammation. The investigators hypothesize that the effect of both interventions on the metabolic risk markers will be partly mediated by the diet-induced changes in the gut microbiota composition.
The purpose of this study is to determine the effect of interactive video game in management of overweight in children. The investigators will evaluate the effect of product versus standard physical activity.
In order to address and curb the high prevalence of childhood obesity in Malaysia, a school-based intervention program, MyBFF@school is developed for implementation in all schools in the country. The program is specific for overweight and obese students and it is hypothesized that by participating in this program, students will be able to control their body mass index.
While eating the majority of energy earlier in the day appears to have a positive effect on weight and cardiometabolic outcomes, it is not clear how eating earlier in the day influences other behaviors that have a circadian rhythm (sleep), other energy balance behaviors important for weight loss (physical activity), and self-reported feelings of appetite control (hunger and fullness). Thus the purpose of this study is to examine the influence of timing of eating on sleep patterns, physical activity, and self-reported feelings of appetite control. It is hypothesized that those who eat the majority of their calories earlier in the day will have greater weight loss than those who eat the majority later in the day.
