Active clinical trials for "Obesity"

High levels of the hormone insulin are associated with risk for heart disease and diabetes, and may make it hard to lose weight. The types of food eaten may affect insulin levels. The purpose of this study is to determine if manipulation of dietary carbohydrate content improves insulin sensitivity (Si), augments weight loss, and promotes weight loss maintenance in healthy adults.

The purpose of this study is to test the hypothesis that a low-carbohydrate diet will impact hormones and other factors that regulate appetite and energy balance, and result in lower energy intake and greater weight loss, than a high complex carbohydrate diet.

The purpose of the E-LITE Study is to evaluate the feasibility and potential effectiveness of two lifestyle interventions in a community based primary care setting. The study aims to assess how changes in diet, exercise, and behavioral self-management affect weight and related risk factors for adults at risk for diabetes and cardiovascular disease.

Self-care behaviors are decisions and actions that people can take to improve their health or cope with a health problem. It is important for people with long-term illnesses to develop and maintain effective self-care behaviors. This study will evaluate the usefulness and practicality of the Collaborative Management in Pediatrics (CMP) program, which is a training program developed to encourage pediatric resident doctors to promote self-management of illness and behavior change among children with asthma or obesity and their families.

The purpose of this study is to investigate the effect of calcium on postprandial lipid profile and appetite.

With the rapid development of society and economy, children's simple obesity is the rising in the world and has become a chronic disease which is one of the biggest public health challenges in the world. It is a serious threat to the health of children and their adulthood. The overweight and obesity is induced by the genetic and environmental factors. The environmental factors are very important, while the dietary factors are the driving factors of many chronic diseases including obesity. This study focus on the dietary intervention of childhood obesity to build healthy intestinal flora. The interventing food was based on a natural health food - fruit and vegetable fermentation liquid, and combined with other probiotic dietary factors, dietary fiber and oligosaccharides. The implementation of the study will help to reveal the fuction mechanism of intestinal bacteria in the obese children and normal children, and to construct healthy micro environment of intestinal flor. According to the positive effect factors, the study will propose a healthy diet and nutrition intervention model for obese children, which is significant to social health especially to children's health. To investigate the accuracy of MRI in quantifying liver fat with magnetic resonance spectroscopy (MRS) as a reference. A secondary goal was to assess the prevalence of nonalcoholic fatty liver disease in overweight and obese Chinese children and adolescents.

Clinics will be randomized to the use of the care pathway for obese pregnant women or standard care. Women who are (1) up to 20 weeks + 6 days gestation into their pregnancy, (2) are carrying one baby (not twins) that is healthy (no life threatening anomalies) and (3) have a Body Mass Index ≥ 30 kg/m², will be included. Data will be obtained from the Ministry of Health's Antenatal Records, charts, and for those in the intervention group, the care path (filled out by the practitioners - the participants' obstetrician, midwife, or family doctor). At the end of the study, practitioners will complete a survey, participate in structured interviews to understand barriers, facilitators, and motivators of using the care path. Primary Objective: To evaluate the feasibility of implementing and testing a clinical care pathway for obese pregnant women in a pilot cluster randomized controlled trial (RCT) Secondary Objectives: To obtain pilot data on A) process outcomes (steps of the pathway, e.g. what % of obese women receive a screen for diabetes) B) clinical outcomes (e.g. what % of obese women receive a diagnosis of diabetes), C) provider outcomes (e.g. Is the intervention acceptable, feasible & efficient? Barriers & facilitators to use, effectiveness? [Structured interviews])

The Feeding-Exercise Trial in Adolescents (FETA) was a randomised controlled intervention study designed to promote healthy weight in overweigh and obese adolescents through a professional-delivered, community-based program with active parents' involvement, focused on supervised physical activity and structured nutritional education. The aim of FETA was to test the efficacy of two intervention groups- physical activity in isolation and combination of physical activity with provision of dietary information- for improving overweight and obesity in adolescents. Our primary hypothesis was that a combined program would be more efficacious than activity in isolation and that activity alone would also be effective compared to control group in improving adiposity profiles in overweight and obese adolescents as well as family activity and feeding habits.

The purposes of the study are: Study Aim 1. To assess the mechanisms underlying the biological effects of short-term walnut consumption on appetite with functional magnetic resonance imaging (fMRI) and assessing neurocognitive function/memory Study Aim 2. To investigate the effects of walnut consumption (48g per day over 5 days) on appetite and satiety by analyzing molecules which regulate energy homeostasis such as adipokines, as well as resting metabolic rate which measures energy expenditure. Study Aim 3. To investigate the effects of walnuts (48g per day over 5 days) on insulin resistance, lipids, and inflammatory markers in obesity as well as the effect of walnuts when consumed as part of a mixed meal, on glucose excursions, insulin secretion and the excretion of gut peptides and free fatty acids.

Obesity is considered one of the most troubling chronic diseases for public health because of its rapid growth in the population. Many are the causal factors of this epidemic, and in recent years studies suggest the involvement of genetic factors in the etiology of obesity as a risk factor for its development. Polymorphism of the FTO gene is being studied in the past eight years and has been indicated as a predictor of obesity in the population, as well as associations in food intake, raising the possibility of influence in the regulation of hunger and satiety. Accordingly, researchers observed changes in levels of postprandial leptin and ghrelin, which can promote appetite and change the quantity and quality of food intake in subjects with the polymorphism FTO.
