Active clinical trials for "Obesity"

This study has been expanded to a four center, open-label, 2-group randomized pilot study evaluating a treatment for obesity.

When delivered online, behavioral obesity treatments have the potential to reach large numbers of individuals with overweight/obesity and produce significant improvements in health and wellbeing. In order to maximize the public health benefit of disseminating these treatments online, this study will use the Multiphase Optimization Strategy (MOST) framework to most quickly and efficiently determine which, if any, of 5 innovative intervention components, alone or in combination, increases the proportion of patients achieving a ≥5% weight loss, and mean weight loss, after a 12-month online behavioral obesity treatment.

Even when they know it can improve health, many individuals with loss of control eating struggle when they are trying to make and sustain new health habits for weight loss and maintenance of weight loss. Impulsivity, characterized by lack of foresight and planning and excessive risk taking, and compulsivity, characterized by inability to break old habitual behaviors, may play a role in refractory obesity. The primary objective of this pilot study is to investigate the effect of a novel neuroplasticity based intervention, cognitive training coupled with transcranial direct current stimulation (tDCS), on measures of impulsivity and compulsivity in individuals with obesity.

This is an interventional research study about clinical, psychosocial, and behavioral factors that impact weight loss, weight maintenance, and cardiovascular disease in socially disadvantaged persons.

Despite standardized intervention strategies, weight loss and weight loss maintenance largely differ from person to person. Factors which may contribute to these individual differences is current object of research. In order to investigate predictors and barriers for weight management and to investigate two different dietary interventions and two different digital tools for weight maintenance, the LION-Study was designed as follows: Step I (screening, baseline phenotyping), step II (weight loss intervention with formula diet), step III (weight maintenance intervention with 4 intervention groups: low carb/newsletter; low carb/app; low fat/newsletter; low fat/app) and step IV (follow-up). Participants are required to attend visits at seven time points. At screening (month 0) a telephone-based screening interview takes place, in order to test eligibility of the potential participant. If the person is eligible, two consecutive baseline face-to-face visits are planned during step I. After completion of the eight weeks weight loss intervention (month 3), an additional visit takes place followed by three consecutive visits in the weight maintenance step (month 6, 9 and 15). The study ends with a final visit after the follow-up (month 27). Additional contacts (face-to-face and telephone) take place during the weight loss intervention step. Participants will regularly receive a bag with the required formula diet meals. During these "pick up" appointments, the study team actively get in face-to-face contact with participants. At the different visits, data are collected by questionnaires, medical investigations (e.g. MRI, motor function, resting metabolic rate), blood withdrawal as well as urine, feces and saliva sampling. Primary objective is to evaluate the effect of two diets (low carb/low fat) and two digital tools (app/newsletter) on long-term weight loss maintenance 12 months after weight loss. Secondary objective is to identify genetic, epigenetic, physiological, psychological and lifestyle factors that predict the success of weight loss and weight loss maintenance.

The main study objective: To evaluate long-limb gastric bypass (150 cm alimentary limb) vs. "distal" gastric bypass (common channel 150 cm) in the treatment of superobesity (BMI 50-60 kg/m2). The main study hypothesis: Distal bypass accomplish an estimated 10-20 % larger weightloss than long-limb gastric bypass 1 year after surgery. Patients subject to distal bypass have more gastrointestinal side effects and more extensive nutritional deficiences compared to long-limb gastric bypass.

This research study is being performed to begin to determine the effectiveness of two dominant bariatric surgery procedures versus an intensive lifestyle intervention to induce weight loss in patients and promote improvements in Type 2 diabetes mellitus (T2DM) in moderately obese patients. T2DM is currently the 6th leading cause of mortality in the United States and is a major cause of kidney failure, blindness, amputations, heart attack, and other vascular and gastro-intestinal dysfunctions. Traditionally, treatments include intensive lifestyle modifications with or without glucose lowering agents. Neither treatment alone, or in combination, results in complete resolution of diabetes and its potential long-term complications. Bariatric surgery has been proven as an effective treatment to accomplish sustained and significant weight loss for those with severe obesity and has been shown to induce long-term remission of T2DM. However, despite enthusiasm for these potential treatment options, it is not clear whether diabetes is influenced by the type of surgery or by the amount of weight lost or if bariatric surgery is more effective than non-surgical weight loss induced by diet and physical activity in T2DM patients with moderate BMIs (30-40kg/m2; Class I and Class II obesity, or approximately 65-95 pounds overweight depending on your height). More well-controlled studies are needed to more completely inform health care decision making and clinical practice in this area. This research study aims to obtain preliminary information regarding the effectiveness of two major types of bariatric surgery, Laparoscopic Roux-en-Y Gastric Bypass and Laparoscopic Adjustable Gastric Banding versus an intensive lifestyle intervention to induce weight loss with diet and increased physical activity.

This is a randomized, double-blinded, placebo-controlled trial designed to assess the effect of the GLP-1 receptor agonist, semaglutide, on visceral and ectopic fat, insulin resistance, inflammation markers, and the downstream effect of cardiovascular risk in people with HIV. The primary endpoints will be visceral and ectopic fat changes over the study period. The secondary endpoints will include changes in markers of inflammation, immune activation, gut integrity, and cardiovascular disease risk assessment.

This study aims to developed an empirically validated psychological intervention protocol for smoking cessation among individuals with excess weight. Participants will be assigned to one of the two following conditions: 1) Cognitive-Behavioral Treatment (CBT) for smoking cessation + a Weight Gain Prevention module (WGP); 2) the same treatment alongside Contingency Management (CM) for smoking abstinence. The main goals are: 1) to assess smoking abstinence rates in each condition at post-treatment and one, three, six and twelve month follow-ups, 2) to assess the effect of treatment conditions and abstinence on weight at each assessment point, 3) to analyze the potential moderating effect of individual variables: socio-demographic characteristics, severity of nicotine dependence and demand, disordered eating, impulsivity and emotional regulation.

Childhood obesity is a significant public health concern worldwide. In China, childhood obesity has dramatically increased as the economy has grown quickly over the past decades. Nonalcoholic fatty liver disease (NAFLD) is tightly associated with obesity, in China, the prevalence of NAFLD in obesity children is 40.0%，the main interventions for NAFLD are lifestyle interventions. Effective strategies to helping students lose weight and alleviate NAFLD through lifestyle interventions may help promote the physical and mental health of obese students. This study aimed (1)to assess the effectiveness of the intervention compared with the usual practice in treating childhood overweight and obesity; (2) to determine the sustainability of the treatment in preventing overweight and obesity; (3) to help alleviate or reverse NAFLD in obesity children. Children with overweight and obesity in six primary schools in Ningbo City, Zhejiang Province will be seleted and randomly divided into two groups: the treatment group and the usual practice group. The participants of the study were students in the third grade of primary school, and the treatment will last for one academic year. This treatment activity on lifestyle interventions will target the dietary and exercise factors of childhood obesity.
