Active clinical trials for "Obesity"

The activity of drug-metabolizing enzymes and transporters evolutes after Roux-en-Y gastric Bypass. Primary aim : To study the intra individual evolution of phenotypical markers of different drug metabolizing enzymes and one transporter (CYP1A2, CYP2D6, CYP2C9, CYP2C19, CYP3A4 and P-gp), using a cocktail phenotypic approach, after Roux-en-Y gastric Bypass.

To assess the potential benefits on mechanical ventilation plateau pressure of pressure controlled mode versus volume controlled mode for laparoscopic bariatric surgery in obese patients (BMI > 35). High plateau pressures encountered in obese patients due to their reduced pulmonary compliance could be lowered using pressure controlled mechanical ventilation.

This is a comparison of metformin versus placebo in NASH patients receiving bariatric surgery for obesity.

This study evaluates the families' and health care professional's experience from using a web based support system including mobile applications for self-monitoring weight and physical activity. Changes in BMI standard deviation score are compared between usual care (control) and usual care with complementary web-based support system (intervention).

This study seeks to investigate why some individuals exercise more than others by focusing on feelings related to exercise. This two part study first examines whether regular exercisers (n=30) and non-exercisers (n=30) differ in how a 30-minute moderate-intensity exercise bout makes them feel. All participants will walk on a treadmill for 30 minutes on two separate occasions and will be asked to report on how they feel before, during, and after exercise, how they anticipate that exercise will make them feel, and how they remembered feeling during exercise. In addition, after exercise session #2, non-exercisers will be randomized to: 1) a brief intervention focused on providing general information about the physical activity guidelines, or 2) a brief intervention which provides general information about physical activity guidelines, but also focuses on affective responses to physical activity. Non-exercisers will complete an identical, third exercise session approximately 1-week following this intervention. Further, all participants will receive a 12-week, Internet-delivered weight loss program following all exercise visits and physical activity will be assessed before and after the weight loss program.

This study aims to evaluate if a web-based support system with daily self-monitoring of weight, use of an activity measuring wrist-band, and communication between the clinic and the parents gives better results on degree of obesity compared with usual care. Changes in BMI standard deviation score (SDS) are compared between usual care (control) and usual care with complementary web-based support system (intervention).

To evaluate a standardized weight-loss program as treatment option for obesity and type 2 diabetes, changes in body composition and metabolic control are investigated in obese patients with diabetes.

In 2014, 24% of UK men were obese. However men rarely participate in weight loss programmes. This study looks at whether two interventions which show promise can help obese men lose weight and keep it off. INTERVENTION 1: Sending text messages to a mobile phone. These will be written as though they come from other men who are also losing weight and include 'how to do it' diet and physical activity tips, combined with friendly humour and support. INTERVENTION 2: The same texts plus promising men money at the start contingent on weight loss achievement. The money will vary over a year according to whether weight targets are met. This is called an endowment incentive and is based on research showing that modest payment helps people change their diet and physical activity. At the 3, 6 and 12 month weighing appointments, men will have the option of continuing with the original weight loss targets of 5%, 10% and 10% or setting lower targets of 5% of body weight at 6 months and 5% at 12 months. This is to maintain motivation and hope for men who do not meet the more ambitious weight loss targets. This study examines if the texts work better with incentives than alone. Both interventions are delivered from a computer and have potential to reach large numbers, including men who don't use health services. This work is done together with obese men and a charity for men to help us find the best ways to deliver the interventions to as many men as possible, including men in difficult life situations. This study will examine whether it is acceptable and feasible to randomise obese men to three groups: texts only; texts and incentive; or to a 'control group' who wait a year and then get the texts for 3 months. The feasibility of recruiting 105 obese men from two regions of Scotland will be assessed. Half of the men will get an invitation letter from their GP. The other half will be approached in the community, given information about the study and invited to take part. Men can take part if their waist circumference is 40 inches and more or their Body Mass Index is 30 or higher. The study examines how long it takes to find 105 obese men who want to take part, how many come back to suitable venues at 3, 6 and 12 months to get weighed and answer questions about their quality of life, lifestyle and motivation. At the end participants will report about their experiences of weight loss and of being in the study.

Unhealthy eating habits inside and outside the home lead to developing obesity, leading to clinical and metabolic disorders, such as insulin resistance, metabolic syndrome, and chronic degenerative diseases, which are the leading causes of death in adult life. The present study compared changes in dietary habits, behaviors and metabolic profiles of obese children whose mothers attended group sessions, with those who received the usual nutritional consultation. The hypotheses were: The mother's training in healthy eating methods, eliminating foods and nutrients that represent metabolic and cardiovascular risk, will change the consumption of these foods in the family, reducing them by 20% and increasing the consumption of food in the same proportion. beneficial, compared to the family of the child who only receives individual consultation. Children with obesity who modify or eliminate metabolic and cardiovascular risk foods and nutrients from their normal diet will have a weight loss of -1.5 BMI compared to children who only receive the usual consultation. Randomized clinical trial, 177 mother/obese child pairs participated, 90 in the intervention group (IG) and 87 in the control group (CG). The intervention group attended six group education sessions to promote healthy eating and 87 received the usual nutritional consultation, over a three-month period. Frequency of food consumption, behaviors during feeding in the house and metabolic profile was evaluated. Data was compared using Student's t or X2.

The purpose of this study is to evaluate whether the Noom Healthy Weight Program, a digital behavior change weight loss intervention, creates a positive relationship with food, compared to a waitlist control group.
