Filter by:This project will examine the effectiveness of a primary care based intervention to help overweight teen girls adopt healthy lifestyle practices. Participants will be adolescent females from Kaiser Permanente Northwest primary care clinics with a body mass index above the 90th percentile. Teens will be randomly assigned to (1) a behavioral weight control program (enriched intervention), (2) brief primary care counseling (low intensity intervention), or (3) usual-care (control). For both of the project's active intervention arms, teens' primary care providers will be given customized plans describing the teen's eating and physical activity habits and instructions on how to best work with these teens and their families. The behavioral weight control program will be specifically tailored for teen girls and will include separate group meetings for teens and parents, follow-up telephone contacts with their group leader, and coordinated feedback from the teen's primary care provider.
This study will evaluate the effects of a drug called betahistine on appetite and food intake in overweight women. Betahistine has been used for many years to treat vertigo (dizziness). It was taken off the market in the United States in 1970 because it was thought to be ineffective for vertigo, but is still used for this purpose in many other countries. Some research suggests that betahistine may reduce appetite and food intake. Healthy overweight women between 18 and 50 years of age may be eligible for this study. Candidates must have a body mass index (BMI) between 30 and 40 and weigh less than 300 pounds. They are screened with a medical history and physical examination, blood and urine tests, electrocardiogram (EKG), breathing test and eating behavior questionnaires. Participants are admitted to the NIH Clinical Center for a 3-day/2-night stay for the following procedures: - Medication: Subjects take either betahistine (in one of three possible doses) or placebo capsules one time on the days of admission to the Clinical Center (day 1), three times on day 2 and two times on day 3. - Blood tests and 24-hour urine collection. - Resting metabolic rate: Subjects rest quietly for 1 hour after awakening and then rest again under a clear plastic hood or while wearing a face mask, breathing normally for about 25 minutes. - DEXA scan to measure body fat, muscle, and bone mineral content: Subjects lie on a table above a source of X-rays while a very small dose of X-rays is passed through the body. - Meal studies: Subjects food intake is measured on days 2 and 3. - Questionnaires: Subjects complete questionnaires about how hungry or full they are feeling and rate how much they liked the foods they ate.
In the county of Oppland, Norway, questionnaires addressing physical and mental health and socioeconomic status is issued to all (1960) families who meet for the pre-school assessment at the public health clinics in 2007. Particularly growth, physical activity and diet is addressed. Families who have children with a BMI >18.9, which corresponds to BMI>30, and living in selected municipalities in the county are invited to participate in a 5 year intervention program in order to avoid future overweight conditions in children. Similarly overweight children from the rest of the county serve as controls.
The purpose of this study is to determine whether a combination of naltrexone SR and bupropion SR is safe and effective in treating obesity and leads to greater weight loss when given with a group lifestyle modification program than with group lifestyle modification alone.
After a three month weight loss phase involving the use of meal replacements, participants are randomized into different weight loss maintenance conditions. Aim 1: To test the hypothesis that the meal replacement (MR) and reduced energy density eating (REDE) interventions, when added separately to the LEARN program, will produce superior weight loss maintenance compared to a LEARN-only intervention. Aim 2: To test the hypothesis that the weight loss maintenance condition that combines MRs and REDE will produce better maintenance of weight losses than either individual component and than the LEARN-only condition. Aim 3: To test the hypothesis that the two conditions receiving the REDE intervention will experience longer-lasting improvements in the energy density and nutritional composition of the diet compared to the two non-REDE conditions.
Metabolic syndrome consists of a group of co-occuring conditions that increase an individual's risk of developing heart disease, stroke, and diabetes. The purpose of this study is to evaluate the long-term effectiveness of chloroquine, a protein-activation medication, at reducing the progression of atherosclerosis in patients with the metabolic syndrome. Sub-study: Vascular endothelial growth factor(VEGF)and Cardiometabolic Risk, The purpose is to determine if the association of VEGF with atherosclerosis indicates that it should be a marker of the disorder.
Metabolic syndrome consists of a group of co-occuring conditions that increase an individual's risk of developing heart disease, stroke, and diabetes. The purpose of this study is to evaluate the short-term effectiveness of chloroquine, a protein-activation medication, at improving metabolic syndrome.
The purpose of the study was to design a weight management program for Mexican American youth and to determine the effectiveness of the program for weight management compared to a self help program. 1. At the end of 6 months, individuals randomly assigned to Intensive Intervention (II) (instructor/trainer led intervention) will lose more weight than individuals assigned to Self Help (SH) only. 2. At the end of 1 year, individuals randomly assigned to II will maintain their weight losses better than individuals assigned to SH. Secondary hypotheses will include examination of main effects and interactions at the end of 6 months with the following secondary dependent measures: treatment adherence (e.g., attendance, food diaries, exercise diaries), blood levels, changes in percent body fat, overall psychological functioning (PEDS-QL 4.0), and eating behaviors as assessed by food frequency checklists.
This study will determine whether resting beta cells (cells in the pancreas that produce insulin) for 2 weeks will improve the ability of patients with Type 2 diabetes mellitus (T2DM) to make insulin. Beta cells can rest by giving patients insulin shots. The study will also examine how teenagers with T2DM feel about having diabetes and explore differences between young people with and without T2DM. This study includes patients 12 to 25 years of age with T2DM who are overweight and who were diagnosed within 2 years of enrolling in the study. Healthy individuals of normal weight or who are overweight are also eligible. Candidates are screened with a medical history, physical examination and laboratory tests. Participants with T2DM are assigned to one of two groups. Group 1 takes an anti-diabetes medicine called metformin and follows a diet prescribed by a study staff dietitian for 2 weeks. Group 2 takes metformin, follows the prescribed diet, and receives insulin through a pump under the skin for 2 weeks. During these two weeks, all participants have the following tests: - Frequent blood sugar checks. - Oral glucose tolerance test (routine diabetes test in which blood samples are drawn before and several times after the subject drinks a sugary solution). - Arginine stimulation to test the response of the body to arginine, a normal ingredient of food that stimulates the release of insulin. Two catheters are placed into veins in the arms, one to administer a liquid containing arginine, the other to draw the blood samples. - Ultrasound of the blood vessels in the neck to check for hardening of the arteries. - Metabolism test to measure the amount of oxygen used during rest. The subject breathes normally during rest while wearing a canopy over his or her head for about 20 minutes. - MRI scans of the abdomen to examine the amount of fat in the belly (at the beginning and end of the study) - DEXA scan to determine percent body fat. - Tests to explore quality of life and feelings about health, work or school, friends and family. - Exercise testing on a treadmill or stationary bicycle. - Genetic studies for information on diabetes and obesity. Normal volunteers have blood draws, oral glucose tolerance testing, MRI scan, DEXA scan, psychological testing, exercise testing, and genetic testing. ...
This exploratory study is designed to evaluate various pharmacodynamic effects of subcutaneously (SC) infused or injected pramlintide in obese, nondiabetic male and postmenopausal female (not on hormone replacement therapy) subjects. The study will also assess the safety and tolerability of pramlintide administered by SC infusion or injection.
