This goal of this randomized controlled effectiveness trial is to compare the effectiveness of a peer-led health lifestyle intervention (Peer GLB) versus usual care services in two supportive housing agencies in New York City (Pathways to Housing [PTH] and Federation Employment and Guidance Service [FEGS]) serving diverse clients with serious mental illness who are overweight or obese. The intervention follows the Group Lifestyle Balance curriculum derived from the Diabetes Prevention Program and that has been shown to help people achieve clinically significant weight loss (equal to or greater than 5% weight loss of initial weight). The intervention will be delivered by trained peer-specialists employed at the supportive housing agencies and supervised by the study team. Peer GLB is a 12-month group intervention that focuses helping people lose weight by improving people's diet and increasing their physical activity and consists of weekly core group sessions (3 mo.), bi-monthly transitional group sessions (3 mo.), and maintenance monthly sessions (6 mo.). We plan to enroll 300 clients with serious mental illness who are overweight/obese (BMI equal to or greater than 25) from our two supportive housing agencies. Clients will be randomized to either the Peer-led healthy lifestyle intervention or usual care conditions. The primary outcome for this study is achieving clinically significant weight loss (equal to or greater than 5% weight loss from baseline weight) at 12 and 18 months post randomization. The secondary outcomes for this study include overall reductions in weight, waist circumference, blood pressure, and improvements in physical activity, self-efficacy, recovery and health-related quality of life. Repeated assessments will be at baseline, 6, 12 and 18 month post randomization. Primary Hypothesis: Peer GLB participants will have a higher proportion of persons achieving clinically significant weight loss (equal to or greater than 5% weight loss) at 12 and 18 months than UC participants. Secondary Hypothesis: At 6, 12, and 18 months post-randomization, there will be significant reductions in average weight, waist circumference, blood pressure, and significant improvements in physical activity, self-efficacy, recovery, and health-related quality of life in Peer GLB compared to UC.

A 20 episode video game called Mommio simulates parent-child feeding interactions for parents of 3-5 year old children within a storyline addressing a problem commonly reported by parents (getting their 3-5 yo to taste a vegetable, which is often a first step toward eating the vegetable), thereby training parents in effective food parenting practices. This research evaluates whether the 20 episodes targeting barriers identified by parents across five levels of difficulty influences vegetable parenting practices and children's dietary intake.

This study will examine whether hesperidin, a major component of citrus fruits, affects how the body responds to insulin in healthy and obese people. Laboratory studies suggest that hesperidin treatment lowers blood pressure, lowers blood sugar and increases blood flow. This study will see if hesperidin improves insulin resistance or insulin's effects on blood flow in people with insulin resistance. Healthy normal weight or overweight people between 21 and 65 years of age may be eligible for this study. Participants are randomly assigned to take hesperidin or a placebo (inactive dummy pill ) for a 4-week treatment phase.

This project is a randomized controlled trial to compare the efficacy of two interventions- one based on Acceptance and Commitment Therapy (ACT) and one based on Self-Regulation (SR)- and a control group (called weight loss only (WLO)) on 24-month weight loss outcomes. All participants will first participate in an initial 4-month standard behavioral weight loss program. Participants will be randomized into 1 of 3 groups and receive a 3-part workshop; the ACT workshop will teach ACT skills including acceptance and mindfulness techniques designed to promote behavior change and health behavior persistence consistent with one's core values. The SR program will focus on self-regulation, regular weighing, and modeling behavior on successful maintainers. The WLO group will receive a control workshop focused on cooking demonstrations and general nutrition topics.The primary outcome is weight loss at 24 months. The secondary outcome is change in psychological flexibility, a critical component of ACT interventions and a potential innovative mediating mechanism. Primary Hypothesis: At 24 months, the ACT group will show significantly greater weight loss as compared to the SR and WLO groups.

The goal of this pilot clinical study is to perform a randomized placebo-controlled study to assess the beneficial effect of a 3 month-treatment with DUAVEE vs. placebo on glucose homeostasis and body composition in 20 post-menopausal women. The recruitment will be performed at Tulane Health Sciences Center.

Obesity



Insulin Resistance and Reward

November 2014 - December 2018
Obesity is a common problem in the veteran population as at least 1 in 3 Veterans are obese. When obese people eat food they have less response in areas of the brain that sense pleasure (reward). Decreased pleasure response to food predicts future weight gain. It is not known if this poor brain response is reversible or why obese people's brains respond this way. Insulin in the brain regulates the brain's sensing of pleasure. As people gain weight the function of insulin becomes impaired. We will study if impaired function of insulin is related to a poor brain response to food and if this brain response predicts voluntary intake of food and response to a diet. We will also study if improving the function of insulin with weight loss improves the brain response. These studies will improve the understanding as to why weight loss is difficult and inform us if improving insulin signaling is a potential way to treat obesity.

The purpose of this study is to examine how physical activity and lifestyle factors influence postoperative recovery and postoperative complications after bariatric surgery. The hypothesis is that physically active people, with a healthy alcohol consumption and non smokers have shorter lengths of hospital stay, shorter sick-leave, fewer re-hospitalizations and fewer re-operations, fewer complications as well as a faster recovery after a surgical procedure. The investigators also hypothesize that possible risk factors for non-surgical postoperative complications e g abdominal discomfort are also life-style related factors such as smoking, high alcohol consumption, low level of physical activity, as well as other risk factors such as prior frequent abdominal pains (e g irritable bowel syndrome symptoms), high levels of anxiety and/or depression, difficulties with coping with the changed food intake regimen after obesity surgery, and generally high sensitivity for painful-sensations and nausea. First aim of this study is to investigate how life style factors prior to obesity surgery are related to hospital stay, sick-leave, immediate postoperative complication rates and the rate of resumption of QoL and normal physical function. The second aim of the study is to identify risk factors for the development of chronic abdominal discomfort and dumping symptoms after obesity surgery.

The purpose of this research study is to see whether wearing a weighted vest during a period of active weight loss can decrease the loss of muscle and bone that occurs during weight loss. We will also determine if study participants who wear the weighted vest will have greater improvements in physical function and self-reported disability, pain, stiffness, fatigue and quality of life. This knowledge could impact weight loss programs designed for older adults. Hypothesis: Participants randomized to VEST will experience similar weight loss, but less loss of lean mass and bone density, than participants randomized to Control.
