Filter by:The aim of the study is to find new clinico-biological and medical imaging parameters associated with non alcoholic steatohepatitis in overweight and obese patients.
The aim of this study is to investigate the effects of acute and short-term intervention with fish oil on inflammatory markers in overweight subjects.
A large proportion of the adult population in the United States qualifies for weight loss treatment based on the NIH treatment recommendations, but traditional clinic-based weight loss treatments have a number of limitations. For example, access to healthcare facilities is limited among people living in rural communities and people of low socioeconomic status, yet a disproportionate number of these people would benefit from services. Internet-based weight loss interventions have been used to deliver services to these populations, but these "e-Health" interventions suffer from a number of limitations and produce only modest weight loss. The limitations associated with internet-based interventions include decreased use of the internet application over time; patients must logon to the internet to receive treatment recommendations, yet few patients regularly logon to the application and this negatively affects treatment outcome. An additional limitation is the quality of self-reported food intake, exercise, and body weight data that participants enter into the internet application or report to their online counselor. Self-reported data are associated with error and accurate data are needed to formulate effective treatment recommendations for participants. Lastly, most applications rely on asynchronous communications between the patient and the counselor, and patients do not always receive personalized treatment recommendations in a reasonable amount of time (1 to 3 days), which limits the extent to which the recommendations result in behavior change and weight loss. The purpose of the proposed pilot and feasibility project is to test the efficacy of the Remote Intervention for Diet and Exercise (RIDE) e-Health application at promoting weight loss compared to a control condition. The RIDE e-Health application addresses the limitations of internet-based interventions that are noted above. The application relies on novel technology to collect near real-time food intake, body weight, and exercise data from participants while they reside in their free-living environments. These data are transmitted to the researchers in near real-time: food intake data are collected and transmitted with camera and Bluetoothenabled cell phones using the Remote Food Photography method that was developed by this laboratory, body weight data is automatically transmitted daily from a bathroom scale using the same phones, and accelerometry is used to collect exercise data that is transmitted via the internet. These data are analyzed and personalized treatment recommendations are sent to the participant in a timely manner, e.g., every 1 to 3 days, using the cell phones. The RIDE e-Health application was developed based on learning and behavioral theory to maximize behavior change and weight loss. The findings of this study will have significant implications for the affordable delivery of effective weight management interventions to patients with limited access to health care.
The study seeks to discover whether peer rejection increases the value of food relative to peer interaction in overweight individuals. After playing a computer game that randomly simulates peer rejection or peer acceptance, participants will play another computer game that will assess the value of food and social interactions. Overweight individuals may be more likely to resort to food in moments of distress and less likely to choose to interact with a peer to reestablish their sense of belongingness.
This study is designed to evaluate the feasibility and provide preliminary evidence for efficacy of a 12-week contingency management intervention to promote weight loss in overweight and obese low income adults in a community-based clinic. The study has three primary goals: (a) to determine if the contingency management treatment can be effectively applied to a new application, weight loss; (b) to obtain preliminary evidence for contingency management's efficacy in promoting weight loss and improving treatment retention, diet quality, physical activity levels, and self efficacy; and (c) to identify barriers and challenges to implementing contingency management for weight loss among low income patients.
The purpose of this study is to evaluate the effectiveness of a life style counseling programme designed for overweight and obese children and their parents in groups compared to traditional individual counseling in the pediatric outpatient clinic and the community. The two interventions are both hospital and community based.
This purpose of this study was to test the use of chewing gum as an adjunct to lifestyle modification to facilitate appetite control and weight loss in overweight and obese individuals.
The purpose of this study is to determine if a low fructose intake could have an impact on weight loss, uric acid levels and the components of the metabolic syndrome (glucose, cholesterol, triglycerides, insulin resistance, high blood pressure).
The goal of this study is to determine the association between genotypes and diet. The weight and weight loss data are already available from the previously completed study called: A to Z Study - Benefits and Risks of Alternative Weight Loss Strategies - A Clinical Trial, which was performed from 2003-2005 at Stanford University. In the present study, Interleukin Genetics will obtain DNA samples from the previously enrolled study subjects to investigate genetic influence of the response to macronutrient compositions of low caloric diets to weight loss.
The purpose of the study is to examine the extent to which two different reward systems implemented in the context of a multi-family pediatric weight management group differentially promote adoption of healthy eating and activity habits among overweight and obese 8-17 year old youth. Participants will be randomly assigned to one of two reward conditions: rewards for attendance only or rewards for attendance and goal attainment. We hypothesize that all participants will demonstrate significant increases in healthy nutritional choices and physical activity and significant reductions in sedentary activity from pre-intervention to post intervention. We expect that participants in attendance plus goal attainment reward condition will demonstrate significantly greater improvements than participants in the attendance only condition.
