Filter by:A total of 75 subjects will be recruited for this study (25 normal weight, 25 overweight, 25 obese). In each subject blood volume will be determined using the minimally invasive carbon monoxide-rebreathing method (substudy 1) and iron absorption will be measured from a test meal labeled with stable iron isotopes. The effect of ascorbic acid on iron absorption will further be determined using a second labeled test meal (substudy 2). In addition, inflammation, hepcidin and iron status will be determined. In order to study the effect of body fat content on blood volume and iron absorption weight and height will be measured, and body fat will de determined by dual energy X-ray absorptiometry.
Morbid obesity and its associated metabolic diseases are on the rise in the United States. Currently, the best treatment for obesity is bariatric surgery where both roux-en-Y gastric bypass and sleeve gastrectomy offer substantial weight loss. Unfortunately, 20% of patients who undergo bariatric surgery fail to lose enough weight defined as less than 50% of excess body weight loss or regain of weight. For those patients who fail to lose weight after bariatric surgery and have failed maximal medical therapy and diet supervision, the treatment is re-operation and revision. Re-operation of the abdomen carries significant postoperative morbidity and mortality. The investigators propose to use the Apollo OverStitch endoscopic suturing device that has already been approved by the FDA as an option for bariatric surgery revision without having to re-operate on the patient. The investigators believe that the endoscopic technique may be able to provide weight loss without having to re-operate on the patient.
The major goal of this project is to evaluate an innovative approach to obesity involving modification of the home environment. The project also will evaluate if home environment modification is more effective when supplemented with distress tolerance and related skills training.
Childhood obesity has more than tripled in the past 30 years. From 1980 to 2008, the prevalence of obesity among adolescents aged 12 to 18 years, increased from 5.0% to 18.1%.1 Although several pediatric weight management programs are available, access to these programs may not always be possible. The proposed study will be an ongoing research program with approximately 40 children ages 12-18 years enrolled into the study over a year. All study participants will participate in a baseline evaluation which will include body composition measures, aerobic testing, as well as nutrition and physical activity questionnaires. Study participants will be assigned to the clinic-based group. The clinic- based group will participate in a 12-week multi-disciplinary weight management program. All study participants will then participate in a 12-week follow-up evaluation similar to the baseline visit. New participants will be enrolled every 12 weeks. Every 12 weeks, active participants (those that have completed a minimum of 12 weeks) will have the option to continue in the program or, discontinue their active participation in the program and enroll into the maintenance phase which will consist of measures only every 12 weeks. The objective of the proposed study includes examining the efficacy of the clinic-based, multi-disciplinary, pediatric weight management program.
Individual food preferences are not considered in designing weight-loss therapies. This project will determine if short-term weight-loss is improved by matching participants with diets that reflect their genetically-determined food preferences.
The specific objective of this research proposal is to determine the short-term efficacy of a primary care-based weight control intervention in which successful volunteer peers deliver a group-based program. The purpose of the study is to conduct a pilot randomized controlled trial (RCT) of a successful volunteer peer-led weight control program compared to a control condition to determine intervention efficacy at 3 months. Six peer leaders from 2 primary care clinics will be recruited and trained to conduct the intervention. Overweight and obese patients (n=80) will be recruited (randomized by individual) to determine weight loss at 3 months (primary outcome). The program consists of 12 weekly weight loss sessions led by a successful volunteer peer leader using an adaptation of the Diabetes Prevention Program to help participants lose weight.
The purpose of this study is to determine if use of a virtual reality platform, Second Life, is more effective than traditional face-to-face methods for maintaining weight loss in overweight and obese individuals.
Randomized cross-over design with 10 male subjects and 3 campaigns to test whether the negative effects of bed rest (6º head-down tilt) on the various systems of the body and the consequences to health of simulated weightlessness can be counteracted by the use of a defined training programme.
The study purpose was to evaluate the effects of portion sizes on body weight and energy intake in a free-living setting. 223 healthy adults were recruited from an urban worksite and randomized to one of four groups for a six-month period. The groups were: 1) 400 kcal box lunch; 2) 800 kcal box lunch; 3) 1600 kcal box lunch; or 4) no box lunch. Participants were required to pick up a box lunch every week day for six months. Control participants did not receive a box lunch and were instructed to eat their usual lunch. Participants were weighed and dietary intake measured at baseline, one, three and six months. It was hypothesized that at six months, participants in the 1600 kcal box lunch would gain more weight and have higher energy intake than those in the other groups.
This 3-armed randomized controlled trial aims to evaluate the effectiveness of The Microclinic Behavioral Health Program in improving obesity and diabetes risk factors through a behavioral intervention program structured to enhance and promote social-network interactions and social support. The full version of the Microclinic Behavioral Health Program (Full MCP) with program-activated social-network interactions-with shared access to diabetes education, technology, and group support to promote weight and metabolic control through diet, exercise, medication adherence, and blood pressure management. Participants play a role in the collective effort to combat diabetes and solidifying self-management behavioral skills through peer-monitoring and encouragement of lifestyle behaviors. The study may yield valuable information on the impact of social support and social network interactions for enhancing body weight and blood sugar control. We compare the full MCP intervention, to a basic MCP intervention with more limited classroom interaction, and to an parallel monitoring control arm. And we aim to understand how metabolic changes over time relate to the cross-propagation of health behaviors between persons in social networks. This Microclinic Behavioral Health Program was established in collaboration with the Royal Health Awareness Society (RHAS) and the Jordanian Ministry of Health (MoH).
