Filter by:Type 2 diabetes and prediabetes, which are mainly caused by a lack of physical activity and excess weight, put people at an increased risk of cardiovascular disease. This study will compare the effects of a weight loss diet versus a weight loss diet plus an exercise program on body composition and cardiovascular factors that are early predictors of future cardiovascular disease in overweight and obese people with type 2 diabetes and prediabetes.
To evaluate the effects of a family-based intervention program intended for parents of pre-school children (4-6 y) with overweight and obesity (according to Cole et al), and to investigate if treatment has an effect on metabolic parameters. In a randomised controlled trial evaluate the three separate family based intervention programs and to investigate if treatment has an effect by correlating the parameters described above with BMI, before and after the intervention program.
This study seeks to look into the effects of oligofructose supplementation on appetite, energy intake, and body weight and body composition in overweight subjects. Compared to a placebo product (cellulose) oligofructose is hypothesised to suppress hunger and thereby reduce food intake moderately leading to a decrease in body weight.
The purpose of this study is to determine if 14-19 year old African American adolescents are able to take a daily vitamin D supplement daily for about 4 months and how well a daily dose of 400 IU or 2000 IU vitamin D supplement raises their vitamin D blood level.
Participants will be randomly assigned in one of two groups. Group A: oral supplementation with 4,000 IU of vitamin D (cholecalciferol). Group B: oral supplementation with 400 IU of vitamin D (cholecalciferol). Both treatments will be consumed daily for 6 months. Outcomes will be evaluated at baseline, three and six months. Variables related to leptin resistance will be evaluated. The main hypothesis is that vitamin D will diminish leptin resistance in overweight and obese women. If the hypothesis is confirmed, women will show a reduction in the Resting energy expenditure: serum Leptin ratio (REE: Leptin ratio), as well as a reduction of hunger, body weight, body and abdominal fat and an increase in resting energy expenditure.
The increasing prevalence of childhood overweight has been found to be related to decreased levels of physical activity (PA) and increased energy content of the diet. Childhood offers an opportunity to develop and support health-promoting behaviors. Pacific Kids DASH for Health (PacDASH) is a community-based intervention that links food, PA, and health, and targets overweight children in Hawaii with a goal of preventing further weight gain. Components of the intervention include a food and PA prescription delivered by physicians at community-based health centers complemented with a toolbox of activities, behaviorally tailored messages, and PacDASH educational materials. This project will extend and apply the nationally recommended DASH eating pattern to children and the growing population of Asians and Pacific Islanders. The investigators will incorporate culturally preferred foods, recipes, and PA messages that meet DASH and other national guidelines. The approach will target child food behaviors and social and environmental cues that are important to making healthy food and PA choices and will provide steps to behavior change. Farmers markets at participating health centers are a support resource for activities. Providing access to, coupons for, and guidance about selecting and preparing fresh fruits and vegetables at a convenient health center farmers market will support increased intake of nutrient-rich foods among these children who are overweight and at risk for obesity. Pacific Islanders are among the world's most obese populations while Asians, although of relatively low body mass index (BMI), carry much of their body fat in the upper body and exhibit greater health risk at the same BMI. Through this project, the investigators hope to learn more about body size and composition in children of the Pacific Region for whom there are few national data. In addition, evaluate the effectiveness of a community-based intervention within a health care system on managing overweight in children.
You are invited to participate in a research study to understand more about childhood obesity and how to prevent it. We hope to learn how families influence each others eating habits.
This randomized clinical trial of weight loss treatment will examine if adding personalized, one-on-one treatment session to standard behavioral group treatment will result in greater weight loss, less weight regain after weight loss, and better adherence to the treatment protocol. Everyone who enrolls in the study will receive information on healthy eating, how to increase their physical activity and develop healthy exercise habits and ways to change their eating so that they will lose weight. This information will be provided at evening group sessions. There will be a total of 20 group meetings over an 18-month period that will be held: - every week during the first month of the study, - every other week for the second month - once a month for months 3-12 - every 6 weeks for months 13-18 Participants in the self-efficacy group will also be asked to participate in one-on-one lifestyle counseling sessions with a study interventionist throughout the study. Everyone will be asked to complete questionnaires, two 24-hour dietary recalls over the phone, and have blood tests done every six months (at the beginning of the study, at 6, 12, and 18 months) a total of 4 times for the study.
This study will examine a contingency management (CM) intervention designed to provide incentives for losing weight versus participating in a manual-guided behavioral weight loss intervention alone. Participants in the CM condition will earn the opportunity to win prizes by losing weight and completing activities that contribute to weight loss, such as keeping daily food and physical activity diaries, choosing healthy foods, exercising, and using other weight loss strategies. The investigators will determine if the CM improves weight loss relative to the usual care manual-guided intervention alone.
The purpose of this study is to conduct a randomised controlled trial to assess the sustained effects on weight, selected risk factors and sense of well-being of offering individualized weight management advice in the primary care setting to patients who wish to lose weight; and to identify the key factors influencing the success of the intervention.
