Filter by:This study seeks to look into the effects of oligofructose supplementation on appetite, energy intake, and body weight and body composition in overweight subjects. Compared to a placebo product (cellulose) oligofructose is hypothesised to suppress hunger and thereby reduce food intake moderately leading to a decrease in body weight.
The purpose of this study is to determine if 14-19 year old African American adolescents are able to take a daily vitamin D supplement daily for about 4 months and how well a daily dose of 400 IU or 2000 IU vitamin D supplement raises their vitamin D blood level.
The increasing prevalence of childhood overweight has been found to be related to decreased levels of physical activity (PA) and increased energy content of the diet. Childhood offers an opportunity to develop and support health-promoting behaviors. Pacific Kids DASH for Health (PacDASH) is a community-based intervention that links food, PA, and health, and targets overweight children in Hawaii with a goal of preventing further weight gain. Components of the intervention include a food and PA prescription delivered by physicians at community-based health centers complemented with a toolbox of activities, behaviorally tailored messages, and PacDASH educational materials. This project will extend and apply the nationally recommended DASH eating pattern to children and the growing population of Asians and Pacific Islanders. The investigators will incorporate culturally preferred foods, recipes, and PA messages that meet DASH and other national guidelines. The approach will target child food behaviors and social and environmental cues that are important to making healthy food and PA choices and will provide steps to behavior change. Farmers markets at participating health centers are a support resource for activities. Providing access to, coupons for, and guidance about selecting and preparing fresh fruits and vegetables at a convenient health center farmers market will support increased intake of nutrient-rich foods among these children who are overweight and at risk for obesity. Pacific Islanders are among the world's most obese populations while Asians, although of relatively low body mass index (BMI), carry much of their body fat in the upper body and exhibit greater health risk at the same BMI. Through this project, the investigators hope to learn more about body size and composition in children of the Pacific Region for whom there are few national data. In addition, evaluate the effectiveness of a community-based intervention within a health care system on managing overweight in children.
You are invited to participate in a research study to understand more about childhood obesity and how to prevent it. We hope to learn how families influence each others eating habits.
This randomized clinical trial of weight loss treatment will examine if adding personalized, one-on-one treatment session to standard behavioral group treatment will result in greater weight loss, less weight regain after weight loss, and better adherence to the treatment protocol. Everyone who enrolls in the study will receive information on healthy eating, how to increase their physical activity and develop healthy exercise habits and ways to change their eating so that they will lose weight. This information will be provided at evening group sessions. There will be a total of 20 group meetings over an 18-month period that will be held: - every week during the first month of the study, - every other week for the second month - once a month for months 3-12 - every 6 weeks for months 13-18 Participants in the self-efficacy group will also be asked to participate in one-on-one lifestyle counseling sessions with a study interventionist throughout the study. Everyone will be asked to complete questionnaires, two 24-hour dietary recalls over the phone, and have blood tests done every six months (at the beginning of the study, at 6, 12, and 18 months) a total of 4 times for the study.
This study will examine a contingency management (CM) intervention designed to provide incentives for losing weight versus participating in a manual-guided behavioral weight loss intervention alone. Participants in the CM condition will earn the opportunity to win prizes by losing weight and completing activities that contribute to weight loss, such as keeping daily food and physical activity diaries, choosing healthy foods, exercising, and using other weight loss strategies. The investigators will determine if the CM improves weight loss relative to the usual care manual-guided intervention alone.
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.
