Active clinical trials for "Obesity"

The purpose of this study is to determine the efficacy and safety of 3 combinations of naltrexone and bupropion SR compared to naltrexone alone, bupropion SR alone or placebo.

The primary objective was to assess the effect of SR141716 on weight loss and weight maintenance over a period of one year when prescribed with a hypocaloric diet in obese patients with or without comorbidities. The main secondary objectives were to assess the effect of SR141716 on lipid parameters (HDL-C, TG), glucose tolerance status, the rate of patients with metabolic syndrome, waist circumference, glycemic parameters.

Obesity and osteoarthritis (OA) co-exist in an increasing part of the population. The two diseases intertwine in several ways. The evolution in the population shows a tendency towards deterioration of both by increasing general age and weight. The two diseases share pathogenetic features and the development of one disease increases the risk of the other and may be the onset of a vicious circle. There is a link between treatments of these two diseases as well. There is now solid (gold) evidence that by treating effectively the obesity of patients with co-occurring OA, the functional status is dramatically ameliorated; the short-term results are equal to that of a joint replacement. The long-term efficacy of a weight loss remains to be shown. OA is definitely one of many diseases in which obesity must be taken seriously into account when planning a correct treatment of patients. This trial is an extension of the former CAROT trial NCT00655941. The participants of this trial are recruited for a prolongation of the dietary intervention consisting of a group therapy with low-energy diet in a randomized, two group (each n = 75 patients) study of maintenance of weight loss by continuing with supplementary either 3 x 5 weeks dietary supplements only or once-daily supplement. The hypothesis is that maintenance of the already induced weight loss is most efficiently ensured by the once-daily program.

The purpose of this study is to investigate whether 6 months treatment with the cholesterol-lowering drug rosuvastatin may reduce visceral fat tissue in obese middle aged men.

More and more Americans are becoming overweight. The rates of overweight are especially high in rural areas of the country. Until now, there has been little access to weight management programs in rural areas. This study will examine ways to help individuals from rural counties to manage weight and improve fitness. To do this, three doses of lifestyle treatment (Low, Moderate and High)will be compared to an education control condition. Our principal hypothesis is that both the Moderate and High conditions will have greater weight loss at two years than either the Low or Control conditions.

The study is evaluating the effect of a 14-session cognitive behavioural treatment for childhood obesity. The treatment is family based and 49 families with children with obesity, aged 8-12, will be recruited. Outcome measures are: BMI, waist circumference, self-esteem, social- and psychological functioning, cholesterol, glucose and insulin values, activity level (actigraphs) and a measure of food intake.

The purpose of this study is to objectify the effect of diet and exercise on early markers of atherosclerosis in obese children.

Primary objectives: evaluate the efficacy of noninvasive ventilation (NIV) treatment versus continuous positive airway pressure (CPAP) and life style modification treatment in Obesity Hypoventilation Syndrome (OHS), with PCO2 (first phase) and days of hospitalization (second phase) analyzed as a primary variables and percentage of dropouts for medical reasons and mortality as operative variables. As secondary variables: Measure functional and clinical improvement during sleep and wakefulness, quality of life, echocardiography and the incidence and blood pressure and evolution of cardiovascular events. Objectives secondaries:role of apneogenic sleep events on molecular inflammation, endothelial damage and the genesis of diurnal hypercapnia. Methods:prospective, randomized controlled trial. Patients with OHS will be divided initially into two groups based on their apnea-hypopnea index (AHI) score, >=30 and < 30, using conventional polysomnography. The AHI >=30 group will be randomized to CPAP, NIV or life style modification treatments. The AHI <=30 groups will be randomized to NIV or life style modification treatments. Treatment efficacy at the medium- and long-term will be analyzed by comparing groups. The role of apneic events and leptin in the genesis of daytime alveolar hypoventilation will be analyzed by comparing the daytime PCO2/AHI coefficient between responders and non-responders to CPAP treatment, and the evolution of leptin levels in the four branches of the study. The role of apneic events in metabolic and biochemical alterations and endothelial dysfunction will be analyzed by comparing basal and post-treatment levels of related substances between groups, with and without significant AHI.

The purpose of the Swedish Obese Subjects (SOS) study is to examine the long-term effects of bariatric surgery on overall mortality and obesity-related co-morbidities.

The purpose of this study is to learn whether overweight children who participate in an after school sports program improve their health as much as overweight children in a more traditional health education program.
