Active clinical trials for "Overweight"

The Diabetes Prevention Program (DPP) is highly effective in promoting weight loss in overweight and obese individuals (e.g., 7% average loss of body weight), and thereby reducing the risk of developing weight-related health consequences. One-on-one DPP sessions, however, are costly and the group-delivered DPP version, the Group Lifestyle Balance program (GLB), is less effective (4% average loss of body weight). The aim of this two-arm parallel randomized controlled trial is to increase the effectiveness of the GLB by integrating habit formation techniques, namely if-then plans and their mental practice, into the program. The study will provide evidence-based data on the effectiveness of an enhanced GLB intervention in promoting weight loss and in reducing weight-related risk factors for chronic health problems.

Background: Diabetic kidney disease (DKD) is chronic and often progresses to kidney failure,heart disease and premature death. Unfortunately, the best medical therapies available for DKD today are ultimately unable to prevent its progression, especially in obese patients.Surgical rerouting of food within the gut with a gastric bypass operation (RYGB), improves diabetes and some of its complications. The investigators propose to investigate whether RYGB in combination with best medical therapy in patients with DKD and obesity prevent further deterioration of kidney function over a 3 years follow up period. Study design: This is an international collaboration with leading centres in Sweden and Switzerland in which100 obese type 2 diabetic patients with established DKD will volunteer to be randomly assigned to receive best medical therapy with RYGB or best medical therapy without surgery. Participants will be 18-65 years with type 2 diabetes and impaired kidney function. Yearly measurements of kidney function will then be done over a period of 3 years as a primary outcome to determine whether differences in DKD can be detectable. The study will also examine and compare a) safety of the interventions, b) the health economic impact on direct healthcare costs and Quality of Life in patients as well as c) the value of a new marker of DKD in determining which patients are most likely to benefit from surgery. Overall the study will strengthen the evidence base guiding clinical decisions about the usefulness of RYGB as an add on therapy to best medical therapy in stopping progressive DKD in patients with obesity and diabetes.

This randomized clinical trial studies the feasibility of tailored physical activity intervention that is administered using Interactive Voice Response technology and cell phones. Interactive voice response and health coach support may motivate overweight postmenopausal women to stick to their exercise regimen to reduce the risk of getting breast cancer.

The overall objective of FAME is to examine the metabolic and behavioral links between dietary intake and its subsequent effects on circulating appetite regulating hormones and physical activity levels in Hispanic and African American adolescents.

Hypovitaminosis D is highly prevalent in the general population, particularly in obese individuals. Besides being associated with obesity, vitamin D deficiency seems to be involved in the pathogenesis of insulin resistance and low-grade chronic inflammation. In addition, it has been reported that individuals with low vitamin D levels are at increased risk for cardiovascular diseases. A healthy diet and weight loss are cornerstones in the prevention of cardiovascular diseases. Vitamin D supplementation could increase the beneficial effects of these lifestyle interventions. The purpose of this study is to assess whether vitamin D supplementation in conjunction with a hypocaloric diet improves the cardiometabolic profile of overweight/obese subjects to a greater extent than diet alone.

Our objective in this pilot study is to test the combined effect of a) replacing office workers' sedentary workstations with active workstations (LifeBalance Station) and b) optimizing computer workstation ergonomics on daily occupational sedentary time, cardiometabolic risk factors, musculoskeletal symptom health outcomes and work productivity.

This study is designed to evaluate the effect of koji-extracted beverage fermented with Pediococcus pentosaceus LP28 on BMI and body fat in overweight subjects.

The current project is designed as a 30-day pilot trial to demonstrate the safety and tolerability of resveratrol therapy in overweight adolescents to decrease liver fat, and improve insulin sensitivity to prevent type 2 diabetes.

To examine whether a lifestyle program results in weight loss and thereby delays or prevents progression of pre-diabetes to diabetes, we propose a pilot randomized controlled trial of 6 weeks duration with 30 participants held at Stephanie Tubbs Jones Health Center. Participants are randomized to receive all of the following: nutrition education, exercise instruction, stress management instruction, and culinary education or follow usual care. Outcomes include: blood sugars and cholesterol, weight, waist circumference, blood pressure, diet, physical activity, perceived stress, and class attendance. Analysis is by Intention to treat analysis of variance. Results will be used to help design larger randomized trial in the future.

Pilot study to determine whether daily consumption of blackraspberry powder (high in polyphenols) can reduce markers of inflammation and to determine whether genetics influence baseline levels of inflammatory markers as well as individual's response to polyphenols. A total of 10 males participated in this cross-over study.
