Active clinical trials for "Overweight"

This randomized, controlled trial is proposed to study the effect, in a cohort of racially and ethnically diverse group of overweight and obese pregnant women, of an Intensive Lifestyle Intervention (ILI) which utilize cognitive behavioral strategies to help participants achieve and maintain changes in dietary intake and physical activity habits compared to Usual Care (UC) on gestational weight gain (GWG), infant fatness, and mothers' post-delivery weight retention. The hypothesis is that the percent body fat at birth will be significantly less in offspring from ILI mothers than UC mothers.

Overweight and obesity, which afflicts ~65% of the U.S. population and more than 1 billion people worldwide, increases the risk of developing hypertension. Activation of the renin angiotensin system (RAS) is an important mechanism by which obesity leads to hypertension. In addition to its vasoconstricting and sodium retaining actions, angiotensin II also has potent pro-inflammatory actions including macrophage infiltration and expression of proinflammatory cytokines in target tissues. Adipose tissue and skeletal muscle appear to be a key sites for the generation of proinflammatory cytokines. Although angiotensin II receptor blockade reduces inflammation in many tissues, the effects on adipose tissue and skeletal muscle in humans are not clear. Importantly, the chronic low grade inflammatory state that accompanies obesity complicates hypertension by contributing to insulin resistance and accelerating cardiovascular disease. Therefore, the general aim of the present proposal will be to determine the influence of angiotensin II receptor blockade on adipose tissue and skeletal muscle inflammation and its relation to improvements in insulin sensitivity, if observed, in obese hypertensive humans. To address these aims, 44 obese (BMI>30 kg/m2) hypertensive (BP>140 systolic and/or 90 diastolic) individuals (age=50-65 years) will be randomized to receive 8 weeks of either the angiotensin II receptor antagonist, olmesartan medoxomil, or no treatment in a crossover manner. Subcutaneous adipose tissue and skeletal muscle biopsies will be obtained and insulin sensitivity (intravenous glucose tolerance tests) will be assessed at baseline and following 8 weeks of each intervention. A two week washout period will separate the interventions.

Inclusion of foods rich in fiber, such as flaxseed, is a nutritional strategy for treating obesity. The hypothesis of this study is to compare the effects of three types of flaxseed flour - whole brown flaxseed flour, brown defatted flaxseed flour and golden flaxseed flour in the sensations of appetite and satiety, lipid profile, pressure levels and associated costs in overweight and obese women.

The purpose of this study is to investigate the effect of three diets different in type and amount of fat in weight maintenance and prevention of life-style diseases in obese subjects.

The aim of this study is to determine the prevalence of Insulin Resistance (IR) among overweight and obese adolescents using HOMA-IR scores and identify lifestyle risk factors in the IR and Non-IR group.

An observational, multicenter, national study with retrospective real-life data collection on the combined treatment of sibutramine and topiramate (off-label use) for the treatment of overweight with comorbidity(ies) or obesity. Data from all adult patients, of both sexes, for whom combination treatment with sibutramine and topiramate, both at any dose/dosage, were prescribed between the year 2011 and the beginning of the study will be included in the study.

The purpose of this study is to determine whether robotic assistance can help facilitate adherence, engagement, and weight loss in participants enrolled in a behavioral weight loss program. All participants will be enrolled in the same Web-based weight loss program and take part in "robotic assistance sessions" either early or late in the five-week study. These robotic assistance sessions involve speaking one on one with a robot about diet-related progress.

Examine clinical results of an interdisciplinary weight management program that includes medical evaluation, nutrition counseling, exercise, and behavioral interventions.

This study seeks to assess how different incentive strategies may reduce the initial attrition gap when implementing weight management in a primary care clinic predominantly serving African American patients. This will be done through an innovative research-practice partnership involving primary care, research expertise, and a small business. Participants will be randomly assigned to one of four financial incentive conditions respectively tied to: weight loss, weigh-ins, weigh-ins and weight-loss, and incentive choice. Participants will be followed for 3 and 6 months to assess program reach, sustaining the reach after initial weigh-in, and weight loss outcomes based on records on participant enrollment and subsequent weigh-ins automatically collected through a kiosk at the clinic.

The purpose of this study is to evaluate pedometer use by overweight women during pregnancy. The study will show if a pedometer will help women to limit weight gain during pregnancy. It will also show if it there are other benefits such as decreased diabetes, decreased high blood pressure, decreased rates of cesarean section, and decreased complications for the baby.
