Active clinical trials for "Obesity"

A randomized clinical trial comparing the effect on weight reduction and cardiometabolic risk factors of intermittent energy restriction and a isocaloric continuous energy restriction in obese subjects.

Pediatric obesity has become a critical health problem worldwide, increasing the premature onset of obesity-related morbidities. This phenomenon has induce an increase in the incidence of serious health complications starting in childhood and adolescence. Lifestyle interventions, including diet and regular physical activity, are the cornerstone of current medical management. Unfortunately, these interventions are often ineffective in providing a meaningful and long-lasting weight loss necessary to change health outcomes. It has been demonstrated that an early intervention in obesity in children and adolescents, inducing weight loss by performing bariatric surgery in carefully selected patients, can dramatically reduce the risk of adulthood obesity and obesity-related diseases, including non-alcoholic fatty liver disease (NAFLD). Recent evidence suggest that bariatric surgery can improve metabolic complications and liver involvement in patients affected by morbid obesity.

The aim of this study is to evaluate the effect of cavitation ultrasound focused on localized adiposity and its effects associated with stereodynamic lymphatic drainage. The investigators aim also to know if this procedure will influence the biochemical profile of the individuals concerned, as well as whether it will be found difference between the group that will receive focused ultrasound cavitation associated with stereodynamic drainage and the group will receive only focused cavitation ultrasound.

People with serious mental illness such as schizophrenia and bipolar disorder experience high rates of physical illness and die earlier than people without serious mental illness (WHO, 2005). Health differences seem to be worse among African Americans (Weber, Cowan, Millikan & Niebuhr, 2009). High rates of obesity among this group contribute to health and wellness concerns (de Hert et al., 2011), with African American women at higher risk of obesity than men. Behavioral weight loss interventions (BWLIs) may promote diet and physical activity that lead to weight loss, but healthy food and safe physical activity options are less available in low-income neighborhoods. Peer navigators have been found to be effective in addressing health differences, and may help people living in low-income communities find healthy food and activity resources (Fischer, Sauaia, & Kutner, 2007). In addition, traumatic experiences are common among persons with serious mental illness as well as African Americans, and may impact weight. Through this project, investigators will test two interventions designed to address overweight and obesity among African Americans with serious mental illness. The first is a BWLI designed for persons with serious mental illness and adapted to meet the needs of African Americans. This program has 8-month intervention phase and 4-month maintenance phase. The intervention includes group weight management classes, group physical activity, individual visits to address barriers to meeting weight goals, and weigh-ins. The second intervention is a peer navigator program that assists people with serious mental illness in meeting their health needs in the community. Two-hundred and seventy (270) research participants will be recruited and randomly assigned to one of three conditions: BWLI program, BWLI program plus peer navigator, and treatment as usual (integrated physical and mental health care). Investigators will evaluate these interventions over a 12-month period, and will track weight change, health behaviors, physical and mental health, recovery, and quality of life. Investigators also seek to understand the impact of gender and trauma on outcomes. Investigators hypothesize that peer navigators will improve outcomes over the BWLI program alone. Findings will advance knowledge and services to reduce racial disparities in obesity and comorbid health conditions for African Americans with serious mental illnesses.

Research purpose: The purpose of this pilot study is to assess obese clients for two phenotypes, those testing positive and those testing negative for Food Addiction (FA) (Yale Food Addiction Scale, YFAS) and determining the efficacy of four treatments: usual care (IC, dietary and physical activity instruction), individual motivational interviewing alone (MI), individual MI with pharmacotherapy (MI+P) for improving outcome measures within each phenotype, and pharmacological therapy (P). Background/significance: Obesity has long been an epidemic in the U.S. and other countries. Numerous approaches have been tried to address obesity with limited success. The YFAS is a relatively new, validated instrument that can help researchers and practitioners assess obese clients for food addiction. Meeting the YFAS diagnosis criteria for FA suggests the need for a stronger intervention with close monitoring to assist these clients in self-management of their eating and physical activity behaviors. Proposed methods/approach: The investigators propose assessing obese clients with the YFAS as part of their intake once they are referred to the Healthy Behaviors Clinic by Regional West physicians/practitioners. A nurse researcher with expertise in MI and a nurse practitioner will perform intake assessments, obtain consent and randomly assign participants in each phenotype (positive or negative for FA) to one of three treatment groups (usual care, individual MI alone, and individual MI with pharmacotherapy). Interventions will occur over 6 months. A clinical psychologist with expertise in the YFAS (University of Michigan) will serve as a consultant on this project and a registered dietitian (University of NebraskaLincoln) will serve as a co-investigator. Expected outcomes: The investigators expect that MI and MI+P and P will be more effective in improving outcome measures than IC. We also expect that response to the treatments will differ between the two obesity phenotypes (those testing positive and those testing negative for FA).

A phase II, randomized, double-blind, placebo-controlled, in parallel groups clinical trial to assess the safety and efficacy of dietary supplementation with tryptophan to achieve weight loss, and its neuropsychological effects in adolescents with obesity.

The purpose of this study is to find out which of two programs, MH MOVE! or the enhanced usual care MOVE! program is most effective in improving participation in and completion of MOVE! among Veterans with depression, anxiety, and PTSD. One of the treatments, MH MOVE! provides the standard MOVE! weight management program plus a workbook containing education for management of depression, anxiety and PTSD symptoms to be used during 10 phone based clinician led CBT sessions. The enhanced usual care MOVE! provides the standard MOVE! weight management program plus a workbook containing education for management of depression, anxiety and PTSD symptoms but not phone calls are provided.

The purpose of this study is to determine whether the modulation of dietary lipids are effective in the treatment of obesity and comorbidities.

MOD-6031 is a long-acting reversibly PEGylated oxyntomodulin (OXM) therapeutic. The active moiety is a gastrointestinal neuropeptide with a sequence identical to endogenous human OXM and is an agonist for both glucagon-like peptide-1 (GLP1) and glucagon (GCG) receptors. The peptide is a natural appetite suppressant, secreted by L-cells in the digestive system following food intake leading to a decrease in gastric emptying, satiety after crossing the blood-brain barrier, and regulation of insulin and glucose levels. Thus, MOD-6031 is being developed as a treatment for high risk subjects (obese) to increase weight loss, reduce food intake and increase glycemic control.

The aim of the study is to determine the effect of whole body electromyostimulation (WB-EMS) and/or nutritional on body composition and functional tasks in elderly females with sarcopenic obesity. Seventy-five, non-sportive, independently living women 70 years and older with Sarcopenic Obesity were randomly assigned to either a WB-EMS group ( n=25), a WB-EMS/nutritional supplements (n=25) or a semi-active control group (an=25). The WB-EMS protocol applied one session of 18 min/week of WB-EMS (bipolar, 85 Hz). Nutritional strategy based on a high protein supplement.
