Active clinical trials for "Obesity"

The primary aim of this study is to determine whether reduced intensity behavioral weight loss treatment (rBWL) + Peer Health Coaches yields significantly greater weight loss than rBWL + Mentor Health Coaches and rBWL alone.

The purpose of this study is to evaluate the impact of the 10-week Active and Healthy Families (AHF) intervention on body mass index (BMI) in Latino youth aged 5-12 years.

The purpose of this study is to evaluate the impact on body mass index (BMI) of a 5-session childhood obesity intervention for African American families among children aged 5-12 years. We hypothesize that children participating in the program will experience a reduction in BMI.

Single macronutrients will be consumed before sleep by obese men. Overnight lipolysis will be measured with the microdialysis technique by measuring glycerol concentration and blood flow in abdominal adipose tissue. Morning fat oxidation will be measured with indirect calorimetry. The investigators hypothesize that carbohydrate intake will blunt the overnight lipolysis rate compared to casein protein and a non-caloric placebo. The investigators also hypothesize that casein and placebo will not be significantly different from each other in terms of overnight lipolysis.

Faster recovery from anesthesia is important for obese patients because they are at high risk of respiratory complications following tracheal extubation. Isoflurane has several properties that make it a preferable agent for anesthesia in obese patients. Its main limitation is a longer recovery time due to slower elimination in comparison to other agents. Elimination of isoflurane from the lungs can be accelerated by increasing in patient's minute ventilation, which decreases the level of CO2 in blood (hypocapnia).Isocapnic Hyperpnoea (IH) is a method allowing increased ventilation and therefore enhancement of the elimination of inhalation agents while maintaining a normal blood CO2 level. The investigators will compare recovery time from isoflurane anesthesia in obese patients during standard anesthesia management protocol (control) to a group treated with IH.

The primary objective of this study is to describe the single- and multiple-dose pharmacokinetic profiles of two novel formulations of topiramate and commercially available immediate release topiramate, all dosed with immediate release phentermine.

This study will assess the impact of a national, community-based after-school program promoting physical activity (America SCORES) on obesity, fitness and important cardiovascular risk factors among minority children. The investigators central hypothesis is that established community-based programs, such as America SCORES, can reduce obesity and cardiovascular risk among participants. The 1-year study followed 158 children from 6 public schools, 3 of which were randomized to have SCORES and 3 to "usual care" after-school program. Primary outcomes are change in body mass index (BMI), physical activity (measured by accelerometer), and fitness (aerobic capacity assessed with the 20-meter shuttle test). Cardiovascular outcomes include blood pressure, body composition (assessed using bioelectrical impedance) and waist circumference. The investigators will also measure academic outcomes.

In children treated for intracranial lesions, the 2 factors of the obesity are : the location of the lesion (hypothalamic-pituitary region) and craniopharyngiomas

The purpose of this study is to determine whether participation in a group-based health education curriculum is superior to receipt of standardized health educational materials for children who are overweight or at risk for overweight with regard to achievement of a healthier body weight and improvement of key eating and physical activity behaviors.

More than 1,000 obese people are screened for genetic mutations (MC4R). Those with positive screenings as well as 320 randomly selected people without MC4R mutations are randomized to 2 consultation types: one including recommendations for eating and physical activity behavior, the other with an additional part on genetic determinants and actions in obesity. It is hypothesized that obese people with obesity-specific genetic mutations, and obese people with a family history of obesity, benefit more if the consultation includes additional elements on genetic determinants.
