The Worksite Nutrition Study is 22-week translational study aimed at determining how well a worksite-based nutrition program, as compared to a control group, is able to 1) produce clinically significant weight-loss, 2) improve cardiovascular factors, 3) decrease work absenteeism, 4) improve overall quality of life, 5) improve diabetes control in participants with diabetes, and 6) promote dietary adherence and acceptability. The nutrition program for the intervention group consists of once-weekly group meetings where participants will receive group support and nutrition education on a low-fat, vegan diet.
This study is designed to evaluate the efficacy of two diets, a low glycemic load diet and a low saturated fat diet, in the treatment of adolescents with some heart disease risk factors associated with being overweight, such as high blood pressure, pre-diabetes, and cholesterol problems. The objective of the study is to determine which diet improves these risk factors more. The design of the study is a modified feeding study, which requests that the participants eat all and only the food provided by the study for 8 weeks, most days per week. Dietary counseling by phone will continue between 2 and 6 months of the study and the effects of this maintenance period will be assessed at 6 months time.
A randomized controlled trial to test the efficacy of an after school ethnic dance program plus a culturally-tailored, home-based screen time reduction intervention to reduce weight gain (body mass index) among lower socioeconomic status, pre-adolescent Latina girls.
The purpose of this study is to investigate whether beverages sweetened with fructose promote overconsumption of calories as compared to beverages sweetened with glucose or a non-caloric sweetener.
The purpose of this study is determine whether the combination of naltrexone SR and bupropion SR is safe and effective in treating obesity in subjects with type 2 diabetes.
Rationale: The global prevalence of diabetes, along with its devastating effects on life expectancy and quality of life, continues to increase. Worldwide, the total number of people with diabetes is projected to rise from about 171 million in 2000 to 336 million in the year 2030. Type 2 diabetes accounts for about 85 percent to 95 percent of all diagnosed cases of diabetes and is associated with a number of serious long-term complications, which are a major cause of morbidity, hospitalization and mortality in diabetic patients. More evidence is becoming available that both lifestyle and clinical intervention in the pre-diabetic condition are effective in slowing down progression of pre-diabetes to overt diabetes. Over many centuries, several forms of traditional medicine have developed which are often based on fundamental principles that differ from those of "Western" medicine. One of the most prominent characteristics of Traditional Chinese Medicine (TCM), is a more holistic approach to the functioning and disfunctioning of living organisms. Every healthy organism is in a Yin Yang balance and is considered to be a complex interplay between body and mind. Western medicine relies on detailed classification of diseases, empirical investigations and treatments targeting those disorders. However, "Western medicine" is showing an increased interest in traditional forms of medicine. Objectives: The primary objective of the present study is to determine consistency in classification of DM type 2 in three categories as defined by Traditional Chinese Medicine (TCM) in pre-diabetic subjects. Secondary objectives are to find relationships between diagnosis according to TCM and risk profile according to Western approach (fasting glucose and HbA1c in plasma, age, BMI, waist circumference). Another objective is to find relationships between classification of risk for DM type 2 according to TCM and objective parameters.
The purpose of this study is to examine and compare the effects of alternate-day reductions in calorie intake or daily calorie restriction on the risk for cardiovascular disease and cancer.
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.
