Active clinical trials for "Weight Loss"

The prevalence of overweight and obesity in youth with serious emotional disturbance (SED) exceeds the epidemic levels of overweight and obesity for children in the general population. Associated cardiovascular (CVD) risk factors such as glucose intolerance, hypertension and lipid abnormalities frequently already exist in obese children. Thus, focusing on overweight/obesity in youth with SED is critical to prevent their premature CVD. In 2015 the American Heart Association called attention to mental illnesses in youth as important risk conditions for early CVD and declared the need for transformational change in screening and management of overweight and obesity. Despite this, studies of healthy weight interventions in youth with SED are noticeably absent, and interventions will likely need to be tailored for this population who frequently have impulsivity, oppositional behavior and/or mood symptoms. In the general population, successful interventions targeting youth obesity often include active parental participation. Community mental health programs serving youth typically engage parents as part of routine treatment and therefore provide an unappreciated but potentially important opportunity to address overweight and obesity. The objective of this study is to design and rigorously test an innovative, scalable healthy weight intervention in youth with SED that incorporates parental engagement and provider support. The CHAMPION Trial is a two-arm trial partnering with community mental health organizations in Maryland. We will perform population-based screening to identify youth with overweight and obesity, and recruit and enroll 120 ages 8-18 years with SED with a BMI at or above the 85th%tile. The study will stratify by sex and site and randomly assign participants to receive a) usual care plus educational materials on healthy weight, or b) the 12-month CHAMPION intervention with a health coach who provides healthy lifestyle counseling and support for weight management, a healthy diet and increased physical activity incorporating techniques to engage both the youth and parents. The intervention's first 6 months will include frequent contacts, followed by a 6-month maintenance phase. The primary outcome will be decreased BMI z-score compared to control at 12 months; secondary outcomes include waist circumference, blood pressure, glucose, lipid levels, quality of life, and psychiatric symptoms at 6 and 12 mo. Antecedents of CVD begin early in youth, and those with SED are at particularly high risk. Breaking this cascade of risk factors leading to premature CVD will require capitalizing on the window of opportunity to intervene on overweight and obesity in youth with SED. The CHAMPION Trial will test an innovative, yet practical approach that could be readily incorporated into overall care of youth with SED.

The overall aim is to study the multiple factors determining the variation of weight loss after Roux-en-Y Gastric Bypass (RYGB) and Sleeve surgery. The specific aims are to evaluate: a) what explains the large individual differences in weight loss seen after RYGB and Sleeve surgery, b) if it is possible pre-operatively to identify which patients will not obtain beneficial effects of bariatric surgery in relation to weight loss and quality of life and c) if patients in need of improved care can be identified pre- and/or early post-operatively.

Obesity has become a global epidemic with huge public health implications. Although clinical significant weight loss can be achieved by a combination of diet and behavioral modification, strong metabolic adaptations, with increased appetite and suppressed energy expenditure, are activated, which compromise weight loss maintenance and increase the risk of relapse. The aim of this project is to compare the effects of intermittent versus continuous energy restriction on the compensatory responses previously described using two low calory diets, with a similar macronutrient distribution. More specifically, this study will analyze, in the short-term, if an intermittent energy restricted diet is associated with less appetite and low reduction in energy expenditure when compared with a continuous energy restricted diet. This project can bring large practical benefits concerning the design of weight loss programs to minimize weight relapse.

The potential role of small bowel bacterial overgrowth (SBBO) in weight loss occurring in patients with Parkinson's Disease (PD) has not previously been examined. Our hypothesis was that SBBO is an important contributor to the development of weight loss in individuals with PD. The investigators proposed to 1) examine the role of SBBO in weight loss occurring in patients with PD and 2) determine the response to its treatment with a poorly absorbed antibiotic. The investigators performed a prospective, observational case-control study (Part 1) with an open-label therapeutic component (Part 2). Cases were defined as those PD patients who experienced significant weight loss while Controls were defined as those PD patients who did not experience significant weight loss.

The aim of this study is to evaluate if an internet-based CBT (Cognitive Behavioral Therapy) programme for weight stability after LCD (Low Calorie diet) treatment for obesity, can reduce weight gain and improve weight stability, self reported health, pain, eating behavior, fatigue and mood. Adults with obesity and health problems in primary health care are invited to be part of the study. The geographical area is Orebro county which has in all 29 primary health care centers. Population is 276 000, and according to population studies around 15% of the adult population has a BodyMassIndex (BMI) over 30, which is characterized as obesity according to WHO. Specific objectives are; To evaluate if internet-based CBT treatment after LCD improves weight stability after 1 and 2 years. To evaluate if weight loss improves metabolic parameters such as HbA1c, blood glucose, Cholesterol, Low density lipoproteins (LDL),High density lipoproteins (HDL) , triglycerides (TG) and Bloodpressure (BP) To evaluate weight loss influence on quality of life, body pain, eating behavior, obesity related problems, fatigue and mood, and to see if CBT program for weight stability also improves these factors To evaluate if LCD treatment is a possible treatment for obesity in ordinary primary health care Patients taking part in the study, undergo a 12 week period of Low Calorie Diet (LCD) treatment, followed by a 12 week reintroduction to ordinary food. During this period the patient has contact with the primary health care nurse and doctor. After 24 weeks of treatment, the patient who follows the study is supposed to have lost around 10% of initial weight.All patients losing more than 7% weight during the first 24 weeks, are randomized to either ordinary follow up (group 1) or an internet-based CBT programme for weight stability (group 2). All patients in the study are followed at 1 year by doctor, and at 2 year by nurse visit.

Based on the creation of a somato-autonomic reflex, the stimulation of sensory nerve terminals located in dermatome T6 may cause a reflex, whose efferent pathways end in vagal nerve branches stimulating the gastric wall, similarly to the gastric pacemaker. The aim of this study was to evaluate the effect of percutaneous electroneurostimulation (PENS) of T6 dermatome on appetite, weight loss and dietary compliance.

The purpose of this study is to test the effect of a mobile phone-assisted lifestyle intervention on weight loss at 6 months among overweight/obese Chinese adults, as compared to a control group.

A contributing factor to the rising prevalence of obesity may be increased portion sizes. However, the effect of portion size has not been studied independent of the effect of quantity of food in the context of a behavioral weight loss program. Providing pre-portioned single servings of food may make it easier to reduce caloric and dietary fat intake improving weight loss. In addition, breakfast skipping is associated with obesity and breakfast consumption is associated with weight loss success. Therefore, the objective of the proposed study is to investigate the effect of portion size on consumption of provided breakfast foods in the context of a behavioral weight loss program. Participants will be randomized to 1 of 2 standard 12-week behavioral obesity interventions. The first intervention, serving as a control, will provide participants with breakfast foods in non-portioned containers (Standard). A second intervention will provide participants with the same type and quantity of breakfast foods but they will be provided in pre-portioned single servings (Portion). Dependent variables include the number of calories consumed from the provided foods as well as overall caloric and fat consumption. If the provision of food in pre-portioned servings is effective at decreasing intake, future directions include conducting longer interventions to improve long-term weight loss outcomes in standard behavioral interventions.

The Internet has been used effectively in behavioral weight loss programs. Most of these programs have involved a therapist who provides email counseling. The purpose of this study was to determine whether a computer-assisted weight loss program could be developed (that would use pre-programmed computer generated messages rather than human generated messages) and whether this program would be as effective as the therapist-assisted weight loss program.

The purpose of this study is to determine whether adding a peer-based intervention based on an outward bound model is more effective than a standard behavioral weight intervention for helping adolescents lose weight.
