Active clinical trials for "Overnutrition"

Today the majority of pregnant women in the United States are either overweight or obese at conception with their offspring having greater adiposity at birth, a 2-fold greater risk of later obesity, and neonatal insulin resistance. It was long thought that breast milk composition was fairly uniform among women, having been optimized through evolutionary time to provide adequate sole nutrition for the growing infant regardless of the environmental circumstances. However, recent evidence shows that breast milk is a highly complex fluid with significant inter-individual variation in hormonal and cytokine concentrations. Pervasive maternal obesity is an evolutionarily novel condition for the human species but little effort has yet been made to systematically examine how this novel condition is associated with breast milk adipose-tissue derived hormone and cytokine (adipocytokine) variation, or whether that variation relates to infant metabolic status. The objective of this study is to comprehensively assess the "lactational programming" hypothesis, that is, whether or not recently documented variation in breast-milk composition is related to both maternal adiposity and to infant metabolic status. The central hypothesis is that a graded, dose-response relationship between maternal adiposity and adipocytokine concentrations in breast milk exists and that milk adipocytokine concentrations are associated with altered body composition in their exclusively breast-fed offspring. The results of the study will be used to design interventions to reduce maternal weight during pregnancy and lactation and to augment lactation education materials to focus on the needs of obese breast-feeding women.

Up to 50% of obese patients are not interested in, or ready for, weight loss. Clinical practice guidelines clearly recommend that these patients avoid gaining weight. However, despite this clinical guideline, weight gain prevention interventions are not available in primary care practice. Balance is a pragmatic, randomized controlled effectiveness trial for weight gain prevention for patients within rural community health centers, using a digital health platform.

Obesity and diabetes are a significant global burden and there is an immediate need for novel treatments and management strategies. Our laboratory determined that avocado derived 17 carbon polyhydroxylated fatty alcohols (PFAs) are inhibitors of fatty acid oxidation (FAO) that impart minimal toxicity in mice. FAO is altered in numerous disease states including obesity and diabetes. In these chronic diseases, excessive FAO in muscle and liver mitochondria cause metabolic overload and inefficiency which drives obesity-associated glucose intolerance and insulin insensitivity. The increased FAO that occurs in obese and diabetic individuals depletes several substrates and intermediates of the Krebs cycle, making them less efficient at using oxidative phosphorylation for energy, which can ultimately lead to glucose insensitivity and weight gain. For these reasons, inhibition of FAO is now an established therapeutic approach for the treatment of type II diabetes as reducing FAO: i) improves cellular metabolism to shift towards the more thermogenic oxidative phosphorylation and glycolysis, and ii) reduces hyperglycemia via inhibiting liver gluconeogenesis while improving glucose homeostasis. In collaboration with an industry partner, Advanced Orthomolecular Research (AOR; Calgary, AB), the investigators have developed a supplement containing a blend of 17-carbon PFAs found inside a commercially available food grade avocado powder. The primary objective of this clinical trial is to determine if the avocado derived supplement is safe for oral consumption compared to a placebo-controlled group.

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.

Poor feeding practices during infancy contribute to obesity risk because they interfere with infant feeding self-regulation and appropriate growth patterns as infants transition from human milk and/or formula-based diets to solid foods. The goal of the project is to provide an educational intervention that fosters appropriate maternal responsiveness, feeding styles, and feeding practices via infant-centered feeding.

The goal of this cluster randomized controlled trial is to determine the effect of double duty interventions on double burden of malnutrition, dietary diversity score, and frequency of morbidity among secondary school adolescents in Debre Berhan City, Ethiopia. The main aim is to answer the following questions. What is the effect of double duty interventions on double burden of malnutrition among secondary school adolescents? What is the effect of double duty interventions on dietary diversity score among secondary school adolescents? What is the effect of double duty interventions on among secondary school adolescents?

The purpose of this study is to compare ways of giving advice and providing support to improve diet and physical activity in adult primary care patients with elevated body mass index and dysglycemia.

The purpose of this study is to determine energy expenditure and sleep in response to protein/carbohydrate and fat ratio of the diet over a short-term and long-term period of time.

The purpose of this study is to determine whether a messaging campaign affects the calories ordered for and consumed by children in a quick serve restaurant setting.
