Filter by:Adolescent overweight and obesity have increased dramatically in the past several decades. High schools are well-positioned to deliver weight loss treatment to overweight and obese adolescents, as they have the facilities and staff to deliver a physical activity program, school nurses with the skills to provide counseling, and are easily accessible by adolescents. This exploratory study will test the feasibility and ability of a school-based intervention, consisting of school nurse counseling and a school-based exercise program, to reduce BMI and improve dietary quality, physical activity, and sedentary behaviors in overweight and obese adolescents. If effective, this could prove to be a cost-effective and relatively easy intervention to disseminate widely for significant public health impact.
The main purpose of our study is to examine the physiological adaptations in oxygen transport chain for high-intensity exercise and moderate exercise in overweight and obese humans. The main goals are: 1. To investigate the most effective short-and long-interval training in terms of VO2max, pulmonary diffusion, cardiac output, endothelial function and mitochondrial function. 2. How these physiological adaptations affect the aerobic endurance and performance, and how this training can reduce the risk of cardiovascular diseases related to overweight and obesity.
The purpose of the Deaf Weight Wise study is to test a 16 week, evidence-based, comprehensive program to change obesity-related health behaviors in Deaf people who use American Sign Language (ASL) as their primary language. Participants will be randomized to one of two study arms - immediate intervention or delayed intervention. In addition to the intervention activities, participants will also take part in five study visits over the course of two years. At these study visits, the investigators will administer several surveys as well as conduct biometric assessments. The investigators primary hypothesis is that the immediate intervention group will increase their levels of physical activity and reduce their caloric intake and body weight immediately following the intervention, compared to the delayed intervention group.
Individuals have a significant capacity to adapt to different environments by changing their core metabolic pathways. This adaptation is especially important in regards to diet. Epidemiological research over the last several decades have shown that diets high in saturated fats have a greater ability to cause insulin resistance and the 'metabolic syndrome' while diets low in saturated fats (or a so called 'Mediterranean Diet), reduces the risk for cardiovascular disease. In humans, experimental diets high in unsaturated fats, as compared to high carbohydrate or high saturated fat diets, result in increased insulin sensitivity and improved lipid profiles. In this application, the investigators propose to systematically assess the effects of two diets enriched in either saturated or unsaturated fatty acids and determine the cellular and molecular mechanisms of the apparent increase in insulin sensitivity. The investigators hypothesize that individuals will 'adapt' to the different diets and the investigators will be able to generate predictive alterations in gene expression and metabolites that underlie the alterations in metabolism. In parallel, the investigators will test the ability of these different diets to affect the release of gastrointestinal hormones that may be critical to modulation of appetite.
The purpose of the study is to determine whether calcium plus vitamin D supplementation is conducive to weight and fat loss during energy restriction in very-low calcium consumers.
Prader-Willi Syndrome (PWS) is one of the most common genetic causes of obesity. Obesity is a major source of morbidity and mortality in this population. It can lead to sleep apnea, cor pulmonale, diabetes mellitus, and atherosclerosis. PWS has distinct characteristics that set it apart from other forms of obesity including insatiable appetite and food-seeking behavior which can be disruptive to home and school activities, and can cause severe social and psychological turmoil within families. PWS is also associated with unique hormonal abnormalities, most notably hyperghrelinemia. Ghrelin is a gut hormone produced in the stomach that stimulates food intake during a fast. It is hypothesized that the extremely high ghrelin levels in patients with PWS may cause or contribute to their insatiable appetite. Exenatide, a medication used in the treatment of type 2 diabetes mellitus in adults, appears to suppress ghrelin levels and cause weight loss. It was designed to mimic glucagon-like peptide 1 (GLP-1), an incretin hormone that stimulates insulin secretion and delays gastric emptying, among other effects. In the present study, the investigators will investigate the effects of a 6 month trial of exenatide in overweight adolescents with PWS. The investigators will quantify the changes in weight and body composition, as well as subjective measures of appetite, and concentrations of appetite-associated hormones. The investigators hypothesize that exenatide will improve weight, body composition, appetite, and plasma ghrelin levels during the treatment period.
Increasing physical activity continues to be a challenge among many individuals, particularly those who are overweight. Recent data from the National Health and Nutrition Examination Survey (NHANES) showed that individuals who reported engaging in a variety of activities were more likely to meet national physical activity recommendations compared to those who reported no variety. Incorporating a variety of activities into a physical activity program may be a way to increase physical increase physical activity levels. One method to increase variety in physical activities is to use active videogames. Videogames that use motion sensors allow a gamer to physically perform a variety of activities. Thus, the purpose ot this laboratory-based investigation is to conduct a study to examine the effect of engaging in a greater variety of active videogames on energy expenditure in 30 non-obese, regularly active adults.
Cardiovascular disease (CVD) is the leading cause of death for women in the United States. CVD disproportionately affects underserved populations, specifically low-income, minority, and rural women who have higher obesity rates and experience other health disparities. There is a need for replicable, evidence-based programs that target women, particularly midlife and older women who represent an increasing proportion of the U.S. population, to reduce their CVD risk . StrongWomen - Healthy Hearts is a 12-week, community-based program that has demonstrated effectiveness at improving CVD risk factors, including body weight, diet quality, and physical activity in a controlled, randomized trial conducted with midlife and older overweight and obese subjects in Arkansas and Kansas. The central objective is to rigorously evaluate dissemination of the StrongWomen - Healthy Hearts Program using the RE-AIM framework to achieve maximal public health impact. Expanded dissemination will occur through the Cooperative State Research, Education and Extension Service (CSREES) This partnership will leverage a long and successful collaboration between Tufts University and CSREES that provides strength training programs to older women in 41 states.
The purpose of this study is to compare ways of giving advice and providing support to improve diet and physical activity in adult primary care patients with elevated body mass index and dysglycemia.
To date, there is no clinical evidence on the efficacy and safety of Glucosanol in maintaining weight loss beyond the study duration of 12 weeks. The rationale for this open-label study is to assess the efficacy in preventing regain of loss body weight and safety of Glucosanol in subjects who are overweight or obese over a longer period after the initial weight loss.
