Active clinical trials for "Obesity"

This study will test an intervention program designed to provide developmentally appropriate guidance to parents of infants on responsive parenting and healthy lifestyle to see if that intervention will prevent rapid weight gain in infancy and overweight at age 3 years. Further, compared with control infants, intervention infants will have lower body mass index (BMI) percentiles at age 3. The investigators also hypothesize that control infants will gain weight more rapidly over time.

This study will describe the phenotype (physical and behavioral traits) of overweight and obese people. It will characterize the hormones, metabolism, food preferences, fitness and physical activity levels, sleep patterns and thought processes in people with and without weight problems. Genetic material will be collected for studies of the internal codes that influence body weight. People over 18 years of age from all weight categories (lean, overweight, obese) who are reasonably healthy may be eligible for this study. Participants undergo the following tests and procedures: Physical exam, electrocardiogram, blood and urine tests, instructions for recording food intake for 7 days Metabolic studies for menstruating women. Resting metabolic rate to study how many calories the body burns at rest. Mixed meal test to measure hormones such as insulin that regulate blood sugar. Glucose tolerance test to determine how sensitive the body is to insulin. 24-hour energy expenditure to measure the amount of oxygen breathed in and the amount of carbon dioxide breathed out. Repeat 24-hour energy expenditure. Diurnal blood sampling and temperature assessment to study the body s internal clock. Air-displacement plethysmography (Bod Pod) to measure body composition. Dual energy x-ray absortiometry (DEXA) to measure body fat and bone density. Repeat Bod Pod and DEXA. Anthropometric measurements and bioelectrical impedance to measure height, weight, and circumferences, skinfold thickness, fluid status and percentage body fat. Bromide dilution to measure the amount of water not in cells in the body. Doubly labeled water to measure the amount of calories burned in a 7-day period. 24-hour diet reports. Endothelial reactivity to measure how the blood vessels stretch or dilate for assessing cardiovascular health. Treadmill or bicycle exercise capacity test. Physical activity monitor. Unicorder to detect any breathing difficulties that may interfere with sleep. Fat and muscle biopsy to look for variations in gene expression in fat tissue and muscle. Neurocognitive testing to check memory, decision-making, hand-eye coordination, and reasoning. Evaluation of mood problems and assess personality type. Evaluation to assess the quantity and quality of pain experienced. Taste testing to determine the response to bitter, salty, sweet and sour substances. Occupational therapy evaluation to explore the subject s adaptations, if any, for performing personal, social or professional activities; the subject s views on his or her weight, body size and shape, and strategies to control weight.

The investigators will conduct a 2-arm randomized controlled pilot, feasibility feeding study in which 28 participants will be randomized to receive either a calorie-restricted Dietary Approaches to Stop Hypertension (DASH) diet or a calorie-restricted standard American diet provided by the study for 4 weeks. Participants will be non-Hispanic black or white, generally healthy females (14 black, 14 white). The investigators will collect fecal samples at multiple time points before, during, and after the dietary intervention to analyze for changes in the gut microbiota and functional-level metabolic products. This work will be led by an interdisciplinary team including expertise in bio-behavioral science, microbiology, nutrition science, bioinformatics, and biostatistics all with cross-cutting expertise in health disparities, prevention research, nutrition, the gut microbiota, inflammation and other biomarkers. The rationale for the proposed research is that once the interactions between race, diet, and the gut microbiota are more fully understood, targeted diet modifications may provide new and innovative approaches for the prevention and treatment of obesity and obesity-related diseases.

The aim of this study is to compare the 1-year total body weight loss outcomes for Class 1 and Class 2 Obesity patients who have undergone endoscopic sleeve gastroplasty (ESG) in contrast to medical treatment with glucagon-like peptide-1 (GLP-1) analogues.

Will a laparoscopic Single-Anastomosis Duodenal-ileal Bypass with Sleeve Gastrectomy produce similar or superior results when compared to a laparoscopic Duodenal Switch, as a primary surgical procedure for weight loss in bariatric patients over a 5 year period?

The purpose of this trial is to determine whether a stretching intervention is superior to a usual care control condition (moderate/vigorous activity 30 minutes daily, 5 days per week) for pregnant women from 27 to 37 gestational weeks.

This study examines a redesign of pediatric primary care overweight/obesity treatment, augmenting typical in-person visits with: (1) direct-to-patient video telehealth to tailor counseling advice to families, (2) that leverages certified health coaches as a part of the care team, and (3) creates skills building in real-time within the home environment.

The purpose of this study is to analyse the potential benefits of ingesting a commercially available pre-workout multi-ingredient supplement providing ~90 Kcal. for 25g of powder: carbohydrates -isomaltulose, fructose, maltodextrin- 15 g, essential amino-acids -Beta-alanine -L-arginine AKG, L-Leucine, Taurine, L-citrulline- 6.8 g, Creatine monohydrate: 2g, Guarana Extract: 800mg, total caffeine: 160mg, and Magnesium: 112.5mg) vs Placebo CHO intake on body composition, physical performance, Happiness Score (specially designed by our sponsor company, including different self-reported and validated tests on their short form) and every workout: Self-perceived energy feeling and adherence to the intervention.

This study aims to compare the percentage of total weight lost in long-term follow-up after two surgical interventions (SADIS and OAGB) in patients with morbid obesity BMI between 45-49.9.

The purpose of this pilot study is to conduct a 12-week pilot feasibility study testing usability of the adapt learning tool (AdaptRL)in a weight loss intervention (ADAPT study). Building upon a previous just-in-time adaptive intervention (JITAI), a reinforcement learning tool will generate decision rules regarding which behavior change techniques, in which contexts, are most efficacious for promoting weight loss in a sample of 20 adults.
