Filter by:The management of obesity is challenging and obesity surgery is by far the most effective treatment currently available. Recent medical research indicates that it also improves the management of blood glucose levels in people with type 2 diabetes. Obesity surgery carries different risks and benefits and it is important to balance these by choosing the right procedure for each patient. Therefore new effective strategies to prevent and reduce obesity and its complications such as type 2 diabetes mellitus are needed. This study is designed to see whether a new device called the EndoBarrier Gastrointestinal Liner helps patients manage their blood sugar levels and lose weight. It is a randomised, placebo controlled trial which compares the potential of the EndoBarrier device with conventional drug therapy, diet and exercise for obesity related type 2 diabetes, and their effectiveness on metabolic state (HbA1c reduced by 20% and blood pressure below 135/85), weight loss, and quality of life. It will further evaluate whether any other conditions that may be related to obesity could become less severe and collect information about complications to determine the safety of the device. The study will also perform various measurements and tests to understand the underlying mechanism of the device. After an initial screening visit to determine patients eligibility, they will be invited for 14 subsequent visits. Patients will be randomised into either having the EndoBarrier device or standard medical therapy treatment for 12 months followed by another 12 months follow-up period. They will also be routinely seen by specialist dietitian who will provide dietetic support throughout the study.
The purpose of this study is to determine the effect of a spousal support enhanced weight loss program on weight loss among African American men.
The purpose of this study is to preliminarily validate a parent-focused obesity intervention program for parents of low-income, African American preschoolers who are currently overweight (> 85th BMI %tile). Half of the participants will receive an intervention that is eight sessions in length and carried out in the participant's home. The sessions will target the nutrition and physical activity knowledge of parents and their motivation for changing parenting related to family eating habits and activity level. The remaining participants will receive an attention comparison control condition (ACCC), which includes one home visit, 7 newsletters and 4 monthly support phone calls. It is hypothesized that children of parents receiving the intervention will have decreases in BMI %tile, consume more fruits/vegetables and fewer sugary beverages, and engage in more activity as compared to ACCC.
This study is a randomized clinical trial with two interventions: control group and intervention interdisciplinary group, without cross-over. Control Group (CG): In this type of intervention, the focus will be the development of skills through educational activities on health using the pedagogy of transmission. Interdisciplinary Intervention Group (IG): In this type of intervention, the focus will be the development of skills through educational activities on health that provide the development of autonomy and empowerment for behavior change, based on interdisciplinary motivational strategies. All topics will be focused on the major cardiovascular risk factors considered modifiable. The staff is trained to the techniques of motivational interviewing and transtheoretical model of change and the health issues related to the modification of lifestyle. So this interdisciplinary intervention with adolescents seeks to measure the result of an educational proposal using the techniques of motivational interviewing and transtheoretical model of change, for all professionals involved independent training in health issues related approach to lifestyle modification and the inclusion of family in this process.
The aim of this study is to design and evaluate an educational and behavioral intervention focused on improving nutrition and physical activity habits among preschoolers in Cuenca, Ecuador, with the overarching goal of preventing overweight/obesity and promoting the formation of healthy nutrition/physical activity habits.
Obesity, with its associated co-morbidities, is a major public health challenge. It is estimated that by 2050, 60% of men and 50% of women will be clinically obese. Obesity is associated with increased risk of developing diabetes, cardiovascular disease, and certain cancers. The increasing epidemic of obesity has necessitated the study of the complex mechanisms underlying energy homeostasis. Food intake, energy balance and body weight are tightly regulated by the hypothalamus, brainstem and reward circuits, on the basis both of cognitive inputs and of diverse humoral and neuronal signals of nutritional status. Several gut hormones, including glucagon-like peptide-1 (GLP-1) and peptide YY3-36 (PYY), have been shown to play an important role in regulating short-term food intake. Peripheral administration of PYY or GLP-1 enhances satiety and reduces food intake in animals and man. PYY, GLP-1 along with a host of other hormones are produced by the gut in response to nutrient availability in different regions of the gut and provide an exquisite mechanism of nutrient sensing in response to dietary intake. These hormones therefore represent potential targets in the development of novel anti-obesity treatments. A novel and attractive strategy to induce appetite regulation is the enrichment of foods with components that stimulate the release of GLP-1 and PYY. The short chain fatty acids (SCFA) produced by microbial fermentation of dietary fibre in the colon have been shown to stimulate the release of PYY and GLP-1 from rodent enteroendocrine L cells, via stimulation of the G-protein coupled free fatty acid receptors (FFAR) on colonic L cells. However, it is not known whether the three SCFA, acetate, butyrate and propionate, differentially affect appetite and glucose control. The aim of this study is to compare the effects of increased colonic delivery of acetate, butyrate and propionate on appetite and glucose control in overweight men in a randomised crossover study.
The purpose of this study is to evaluate the accuracy of a new device that may be used for the evaluation and management of malnourished infants and children. The device will measure the levels of two hormones made by fat tissue: leptin and adiponectin.
The investigators aimed to study the effect of supplementation with species of Lactobacillus on anthropometric measurements, body composition, appetite and serum lipid profile in overweight and obese adults
The objective of this randomized, single blinded cross-over study is to investigate effects of daily egg versus yolk-free egg substitute consumption on High Density Lipoprotein (HDL) composition and function in a population of overweight and obese postmenopausal women.
The purpose of this study is to evaluate the effectiveness of a technology-based behavioral Healthy Lifestyle intervention on adiposity (body mass index z-score), blood pressure (mean clinic systolic BP), and heart size (LVM) in comparison to standard care.
