Active clinical trials for "Obesity"

The combination of high blood pressure and having central obesity is an increasing important factor for heart disease in men and women. It can also lead to the early development of hardening of the arteries and increased risk of a stroke. This study will analyze patients' genetic make up to identify who may be at greater risk for heart disease and strokes in relationship to high blood pressure and central obesity.

The primary objective of the study is to test the hypothesis that prolonged re-feeding after VLED induced weight loss improves weight maintenance and eating behaviour

The purpose of this study is to evaluate the efficacy and safety of two doses of VI-0521 compared to placebo in treatment of obesity in an adult population with BMI ≥ 35.

This study is to demonstrate the safety and efficacy of the use of the LAP-BAND surgery in the morbidly obese adolescent population.

The primary objective of this study was to evaluate the efficacy and the safety of sibutramine vs. placebo in combination with a hypocaloric diet on weight-loss in overweight and obese Malaysian subjects.

In the pilot study, Testing Strategies for Weight Loss, we tested two different approaches using financial incentives to encourage weight loss. In the first, we built on previous work showing the effectiveness of 'deposit contracts', in which subjects are given the opportunity to put their own money at risk if they do not lose weight. In this incentive condition, subjects received a direct payment conditional on daily weight loss, and an optional additional payment based on their own contributions to the deposit contract. We matched their contribution 1:1 to make the option of depositing their own money attractive to this predominantly low SES population. In the second approach we built on our own prior work using lotteries to promote drug adherence. In this incentive condition, participants are entered into a daily lottery, and receive any payoffs they earn from the lottery only if they stay on track with their weight-loss goal. Given their popularity in the general population, lotteries hold the promise of providing a cost-effective means of motivating weight loss and making efforts to lose weight more salient to obese patients. Results from this trial indicate significantly higher weight loss in the incentive arms of the trial than in the control group. The low lost to follow-up rates suggest that this approach to providing daily feedback to keep weight loss salient among participants is feasible. Incentive participants who completed the study called in their daily weights an average 95.8% of the time. 17/19 (89.4%) of subjects deposited money in their deposit contracts and 14/17 participants who made initial deposits either held constant or increased their contributions each month. Subjects in both incentive groups lost significantly more weight on average than subjects in the control group (4.0 lbs) (lottery 13.1 lbs, p = 0.015; deposit contract 14.0 lbs, p = 0.003). Of the subjects not lost to follow-up in the two incentive arms (32 out of 38), all of them lost weight. Based on this promising preliminary evidence and supplemental funding from the Hewlett Foundation, we propose an 8-month study with 2 intervention arms to further examine the effect of incentives on long term weight loss success. This study will build on the work to date to examine which intervention is most successful in promoting sustained weight loss. The proposed 3-arm extension will enroll 66 participants from Philadelphia VA with BMIs between 30 and 40, starting with those potential participants who were placed on a waiting list for our previous study after an overwhelming response to the initial mailing.

Obesity is a major public health problem. At least 15 million American adults are obese, and the number is rising. Childhood obesity is also increasing in prevalence and currently affects approximately 11-22 percent of children aged 6 to 11. Childhood obesity is associated with serious negative physical, emotional, and social consequences. Obese children are at high risk for becoming obese as adults; 24-44 percent of obese adults were obese as children. The risk of an obese child becoming an obese adult is especially high when at least one parent is obese. To date, adult obesity is known to be resistant to treatment. In contrast, promising long-term effects have been found with children who received behavioral family-based weight loss treatment. However, even with state-of-the-science programs, a substantial percentage of children (i.e., over 40 percent) regain all or most of the weight lost once treatment ends. The proposed study examined the efficacy of two intervention strategies designed to improve the long-term maintenance of weight loss in children relative to discontinued treatment contact following an active weight loss treatment phase (no maintenance treatment control (NTC).

Primary : effect on weight loss and weight maintenance over 9 months when prescribed with a hypocaloric diet in obese patients. Secondary : effect on HDL-Cholesterol, triglycerides, fasting-insulin, fasting glucose, waist circumference - safety and tolerability

This research study is to evaluate the effectiveness, tolerability, and safety of lamotrigine therapy in the treatment of binge eating disorder associated with obesity. Lamotrigine has been approved by the Food and Drug Administration for the treatment of bipolar disorder, but has not been approved for use in the treatment of binge eating disorder with obesity.

Lifestyle choices,including diet,are conducive to healthy body weights in children. Dairy products and calcium supplementation have been associated with moderation of body weight and body fat. This study was designed to test the following hypotheses with overweight and obese adolescents consuming a controlled diet: Dietary calcium supplementation as calcium carbonate or dairy calcium modulates energy balance in adolescents. Increased calcium in the diet of adolescents will increase fecal fat excretion and thereby decrease fat absorption. Calcium and dairy product supplementation will increase lipid oxidation resulting in an increase in energy expenditure.
