HyperphagiaPrader-Willi SyndromeThe purpose of this study is to determine the effects of transcranial direct current stimulation (tDCS) as it modifies hyperphagia in obese subjects, non-obese subjects, and subjects with Prader-Willi syndrome (PWS).
Family Based Treatment for Weight Loss With Breakfast Prescription
ObesityOverweight3 moreThe purpose of this study is to evaluate whether a behavioral weight loss group in conjunction with a prescribed breakfast can help children between 8 and 12 years of age change their behaviors to help them lose weight and become healthier.
Oxytocin vs. Placebo for the Treatment Hyperphagia in Children and Adolescents With Prader-Willi...
Prader-Willi SyndromeHyperphagiaThe investigators propose a randomized double-blind 8 week treatment trial of intranasal oxytocin (IN-OXT) vs. placebo in 24 subjects aged 5 to 18 years with PWS in order to assess IN-OXT's affect on (1) Eating behaviors (2) Repetitive and disruptive behaviors and (3) Salivary OXT levels.
Taking Action to Thrive - A Healthy Lifestyle Intervention Pilot Study
OverweightObesity and Other HyperalimentationThere have been some preliminary studies, primarily in animals, that suggest that exposure to some of the chemicals in our everyday environment, such as the chemicals found in plastics, may cause weight gain. It is not clear whether this also happens in humans, or whether decreasing exposure to these chemicals can improve success with weight loss when people adopt healthy lifestyle changes. The THRIVE Study is a 4-week group healthy lifestyle education program that is designed to determine whether: changes in dietary habits and the types of personal care products used can decrease a person's exposure to chemicals in our environment that have been suggested to cause weight gain whether any measurable changes in body composition (fat tissue vs. lean tissue) can be seen as a result of participating in the healthy lifestyle program.
Decreasing Stress and Improving Self-control With "Stress in Control" (Sync) Training
StressObesity1 moreThis is a study of treatment approaches aimed to improve self-control and decrease stress and unhealthy/maladaptive behaviors such as drinking, overeating, and smoking. High levels of stress may make it harder to maintain self-control, especially when trying to control our unhealthy behaviors. Training on improving self control and decreasing stress may help decrease unhealthy behaviors. The goal of this new training program will be to decrease a subject's unhealthy behavior by helping them better manage their stress and improve their self control over unhealthy habits.
Understanding the Role of Gut Microbiota in Hyperphagia in Prader-Willi Syndrome
Prader-Willi SyndromeObesityThis study aims to use a high-fiber supplementation, an intervention known to create shifts in the gut microbiota towards a healthier structure, to explore the relationship between gut microbiota, appetite control and feeding behavior in PWS patients.
The Play With Me Study
High Food ReinforcementOvereating2 moreThe obesity epidemic continues to be a major public health concern, with 38% of US adults and 17% of children obese. One factor that has been highlighted as a robust predictor of weight outcomes is the relative reinforcing value (RRV) of food, or how rewarding one finds eating compared to alternative activities. An emerging body of literature has built upon the observed relationship between the RRV of food and weight by hypothesizing that the promotion of alternative reinforcers, or rewarding activities that could take the place of eating, offers a novel approach to decreasing excess energy intake and combatting obesity. We aim to integrate distinct bodies of literature and fill a gap in the evidence by testing whether parenting intervention messages delivered and practiced in the context of shared activities can decrease the RRV of food by making parent-child interactions more rewarding. The ultimate goal of this research is to demonstrate that such an intervention can increase children's motivation to interact with their parent instead of eating a favorite food, demonstrating the potential for positive parent-child interactions to become an alternative source of pleasure.
Individual Differences in Children's Susceptibility to Overeating
ObesityThe portion size of foods has been identified as an important determinant of energy intake in children. It remains to be determined to what extent child weight status and the relative reinforcing value of food may interact with the obesogenic food environment to affect energy intake. The primary aim of this study was to compare energy intake at a meal in normal-weight and obese children when the portion size of palatable, energy-dense foods and a sugar-sweetened beverage was systematically increased. We hypothesized that increasing the portion size of all foods and the beverage at a meal will lead to a significant increase in energy intake in both normal-weight and obese children. Obese children, however, will show a significantly greater increase in energy intake than will normal-weight children. A second aim of this study was to test if children's response to increases in portion size was affected by how reinforcing they find food to be. We hypothesized that, when controlling for BMI, children who find food very reinforcing relative to nonfood alternatives will show a significantly greater increase in energy intake than will children who find food less reinforcing.
